After the flood, if your plastic thermoforming machine is unfortunately flooded, please refer to the following correct treatment methods to minimize the loss. It is recommended to contact professional maintenance personnel for the following treatment methods, and then power on and test the machine after the detection is normal. Before turning on the machine, please start the manual mode, test whether each control action unit is normal, and then turn on the automatic mode.

Electrical part (especially important)

① Disconnect the power supply, and after all the following steps are confirmed to be OK, the power can be turned on again under the guidance of professionals!

Disconnect all power sources, hang a no-closing operation sign on the main switch, and do not work on the plastic thermoforming machine until the power is disconnected.

②Check whether the PLC main board and touch screen have water.

If the PLC main board and touch screen get into water, the internal battery needs to be removed as soon as possible. Otherwise, individual components will remain energized, which will worsen the damage of wetted components.

③ Check whether the electric box is filled with water

If the electric box is soaked in water, ask professionals to remove the electrical components in the entire electric box, open the shell and clean the circuit board and metal contacts with circuit board cleaning solution, including I/O board, 24V power supply, 5V power supply, transformer, AC Contactors, air switches, solid state devices, etc.; locations and components that cannot be cleaned, use flushing. After rinsing, make sure that the circuit board is completely dry before installing it again. If a single unit capacitor or transistor is damaged, you can contact the manufacturer to replace it.

④Dry all electrical components

Use a hair dryer or dryer to fully dry all components. The decomposed and cleaned components can be layered into dry materials. The drying temperature is 50~60℃, and the drying time is 8~10 hours. It is better to choose low temperature for a long time. After drying, test whether the insulation resistance value meets the requirements. It is recommended to use a multimeter for 24V low-voltage lines and components with a resistance range of 100K or higher (the higher the range, the better), and a megohmmeter for 220V and above lines and components to judge whether they are damaged and dry completely.

⑤Electrical components are individually energized and checked

Professionals are required to energize and inspect the completely dry electrical components, and they can be installed and used after the inspection is in good condition.

⑥Other

If the failure of electrical components cannot be avoided after the above operations, please stop using it immediately, and contact the manufacturer's service personnel for replacement or repair before starting the plastic thermoforming machine.

Hydraulic part

①Check whether the motor oil pump has water

If the motor oil pump is soaked in water, the motor oil pump cannot be turned on, because the water entering the hydraulic oil after turning on the motor may enter the hydraulic pipeline system of the machine, causing the metal hydraulic components to rust.

②Check whether the hydraulic oil has entered water

Open the plug at the bottom of the oil tank on the rack, release a small amount of oil, and ignite it with a piece of paper. If it cannot be ignited or there is a crackling sound during the combustion process, it means that there is water in the hydraulic oil; anhydrous copper sulfate test can also be used to see Whether it will turn blue, if it turns blue, it means water. If the oil contains water, the entire hydraulic oil in the tank needs to be replaced. Wipe the tank with a clean cloth before changing the oil. At the same time, check the hydraulic components and pipelines, and deal with them in the same way.

Other parts

①Check all servo motors and drivers

Ask professionals to separate the stator and rotor of the motor, dry the stator winding (the rotor of the servo motor has a strong magnetic force, please pay attention to safety), and use a 100W incandescent lamp to extend into the motor shell for at least 8 hours of drying treatment. After drying, use Shake the meter to detect the insulation resistance must ensure ≥ 0.4MΩ. At the same time, remove the motor bearing and clean it with gasoline to check whether it can be used, otherwise replace the bearing of the same specification.

②Check the lubrication pump

Separate the rotor, stator and pump bladder of the lubricating pump motor. The fixed windings can be dried with a drying hopper. The insulation resistance must be guaranteed to be greater than or equal to 0.4MΩ. Derusting, the gears in the pump can rotate flexibly. Lubricate the lubricating parts to check whether the lubrication is good.

③ Inspection of the whole machine

Check the whole machine, do a good job of cleaning and anti-rust treatment, test each action one by one when starting up, and observe whether there is any abnormality in the action process!

Safety warning

It is recommended to contact professional maintenance personnel to handle the above steps, and then power on and test the machine after the inspection is normal. Before starting the machine, please test whether each control action unit is normal in manual mode, and then open the automatic mode.

LITAI MACHINERY Co., Ltd. was established in 2001, is a professional manufacturer of automatic multi-station plastic thermoforming machine, plastic cup production line, BOPS plastic thermoforming machine, mold, PET sheet extruder and multilayer PP/PS sheet We are a source manufacturer integrating production, R&D, manufacturing and sales of industry and trade. Welcome new and old customers to come to consult!

The thickness of the products of the full-automatic plastic suction machine varies greatly. Some are as thin as paper, as thin as a cultivation flower pot, etc., and they are broken when poked; some are as thick and strong as a bathtub, and can be used for decades without damage. So how to choose a fully automatic press according to the thickness of the product?

According to the thickness of the product, the full-automatic plastic suction machine can be divided into two types: thin plate full-automatic plastic suction machine and thick plate full-automatic plastic suction machine. The automatic sheet blister machine is our common full-automatic plastic suction machine. The thickness of the sheet of the full-automatic plastic suction machine is usually 0.12-2mm, and the source of the board is wide, such as PS, PET, PVC, APET, PE, recyclable materials, etc. There are medicine, hardware, cosmetics, food, etc.; the thickness of the thick sheet full-automatic plastic suction machine is 1.5-8 mm, and the main products produced are light box advertisements, home appliance back shells, refrigerator liner, bathtub and so on. Some products can replace injection molding products, but compared with the injection molding process, the mold cost of the thick plate full-automatic plastic suction machine is lower, the mold production time is shorter, and the efficiency is higher than that of the injection molding machine.

When choosing a fully full-automatic plastic suction machine, you must fully consider your own product characteristics. If you have any doubts during the purchase process, you should make more references. Why is cooling important for the production of full-automatic plastic suction machines? As we all know, in the forming process of the full-automatic plastic suction machine, it is necessary to make the plate contact with the mold for vacuum forming. The mold is repeatedly exposed to the heated sheet and accumulated heat during operation, and when the temperature reaches a higher temperature, it is necessary to wait for the mold to drop to a lower temperature before continuing production. At this point, a cooling system will be used to accelerate mold cooling. During the product forming process, the full-automatic plastic suction machine has a cooling process to enhance the product strength and help the product form. A mold with a built-in cooling structure is the ideal purchase at present, and cooling is required both inside and outside the product in contact with the mold. The semi-full-automatic plastic suction machine is mainly water-cooled and air-cooled, it cools the paper by spraying water mist or blowing cold air. Although spraying water mist and blowing cold air can achieve the cooling effect, the cooling speed from the outside to the inside is slow, but it has the characteristics of wide material adaptability. Non-metallic materials such as plaster and wood can be used.

1. Lubrication: All columns, chains and bearings should be kept in good lubrication condition. Running without lubrication can severely damage the machine and cause column deformation.

2. Water filter and lubricator: observe and record various indicators, and regularly refuel and change water.

3. Keep the working environment clean and hygienic. Scrap around the fuselage, oil stains inside the machine, etc. need to be dealt with every shift.

The annual output value reaches 8 billion to 10 billion yuan.

From the market analysis of plastic products, combined with the full play of my country's original production capacity of plastic machinery products, from 2001 to 2010, the average annual growth rate of domestic market capacity of plastic machinery products in my country is about 6%. In 2000 and 2005, it was 8 billion yuan and 11 billion yuan respectively, and it is expected to reach 14.5 billion yuan in 2010. With the improvement of my country's product quality and the increase of varieties, the share of plastic machinery products in the domestic market will also increase, which is expected to be 70%, 75% and 80% respectively; the total industrial output value of plastic machinery products is 5.6 billion yuan. , 8.25 billion yuan and 11.6 billion yuan. With the increase of my country's product exports, it is estimated that in 2010, the total industrial output value of my country's plastic machine products will reach 14 billion yuan, 2.33 times that of 2000, with an average annual growth rate of about 9%, of which the growth rate from 2001 to 2005 is 10% , the growth rate from 2006 to 2010 was 8%.

From the analysis of the number of plastic machinery products, in 2000 and 2005, there were 55,000 and 75,000 units respectively. 5%, and 35% for other presses.

2. My country's plastic machinery manufacturing industry exports

In addition to meeting domestic demand for general plastic equipment in my country, the export volume of equipment is also increasing year by year. In the past three years, my country's export of plastic machinery products has been in the fastest growing period in history. For a long time, the foreign exchange earned by exports has been around 50 million US dollars. It exceeded 100 million US dollars for the first time in 1998 and increased to 238 million US dollars in 2001, an increase of 31.09% over 2000.

Relevant experts analyzed that, in the future, the export of plastic machinery products in my country will be dominated by injection molding machines. From the analysis of the export quantity, it is estimated that the proportion of various types of machines is: 60.4% for injection molding machines, 6.8% for extruders, 11.7% for blow molding machines, and 21.1% for other plastic machines. In terms of foreign exchange earnings from exports of plastic machinery products, injection molding machines accounted for 74.1%, extruders accounted for 8.1%, blow molding machines accounted for 8%, and other plastic machinery products accounted for 9.8%.

In 2002, the total export value of the plastic machinery industry was higher than in 2001.

What is an automatic plastic cup thermoforming machine? Well, this is a question everyone who is new to this industry would ask. Simply, this is a machine for manufacturing plastic cups. But there are other questions we might encounter. In this article, Litai, automatic plastic cup thermoforming machine supplier, would focus on questions of automatic plastic cup thermoforming machine, aiming to enable you to understand this machine clearly. Besides, automatic plastic cup thermoforming machine of Litai would be introduced at the end of this article, you could click here to turn to corresponding product page to be familiar with this machine. If you want to know more about details of shipping and after-sales service, contacting us directly is welcomed.

Automatic plastic cup thermoforming machine (also known as flat vulcanizing machine, rubber vulcanizing machine, small tablet press, automatic tablet press) is a kind of molding machine, suitable for polymers in the rubber and plastic industries such as PVC, masterbatch and other chemical raw materials It can be used as the basis for batching before mass production in the factory. The plastic or rubber raw material is placed in the mold, sandwiched between the upper and lower electric heating plates, and pressure is applied under the intelligent constant temperature of the electric heating plate to make the raw material shape.

The commonly used materials for plastic water cups are space glass and AS plastic. Space glass, also known as PC engineering plastics, is a widely used material around the world, and its main component is polycarbonate. Lightweight and durable, this material has excellent insulation, elongation, dimensional stability, chemical resistance, and high strength, heat and cold resistance. It also has the advantages of self-extinguishing, flame retardant, non-toxic, and colorable. The disadvantage is that it has insufficient hardness compared with metal, which makes its appearance easier to scratch. 

AS plastic is a copolymer of acrylonitrile (A) and styrene (S). It has moderate weather resistance and is not affected by high humidity environments. It is resistant to general grease, detergents and mild alcohol. It has poor fatigue resistance and is not easy to It cracks due to internal stress, and the material has high transparency. It is often used to make plastic products such as trays, water cups, tableware, toothbrushes, instrument mirrors, and packaging boxes.

The injection molding of the automatic plastic cup thermoforming machine uses the thermophysical properties of the plastic to add the material from the hopper into the barrel, which is heated by a heating ring outside the barrel to melt the material. The material is gradually plasticized, melted and homogenized under the double action of screw shearing. When the screw rotates, the material will push the melted material to the head of the screw under the action of the friction force and shearing force of the falling groove. 

At the same time, the screw retreats under the reaction of the material, so that the head of the screw forms a storage space and completes the plasticization process. Then, under the action of the injection cylinder piston, the screw injects the molten material in the storage chamber through the nozzle at high speed and high pressure. In the cavity of the mold, after the molten material in the cavity has been pressure-maintained, cooled, solidified and shaped, the mold opens the mold under the action of the clamping mechanism, and the shaped product is ejected from the mold through the ejector device.

This is the end of this article, more questions and corresponding answers would be listed in the next article.

WORKING MECHANISM OF PLASTIC THERMOFORMING MACHINE

TYPES OF PLASTIC MOLDING MACHINE PROCESSING EQUIPMENT

2022 is a crucial year for the "14th Five-Year Plan". Whether it is to expand domestic demand to promote new infrastructure, or to replace domestic production to build plastic recycling, technological innovation is the source of living water, and it is also the foundation and "golden key" to consolidate the development of dual recycling. Accelerating scientific and technological innovation and upgrading and transformation has become an inevitable move for rubber and plastics enterprises to seize the commanding heights of the future and market competition.

Asia-Pacific Chinaplas will be held from July 18 to 21, 2022, with 12 major exhibition halls, with an exhibition area of 120,000 square meters, with 2,000+ global high-quality suppliers, and a huge amount of mechanical technology and innovative materials will be unveiled. Qingdao World Expo City International Convention and Exhibition Center. It is expected to attract 150,000+ professional visitors from the rubber and plastics application industry. Standing at this new starting point, let us gather at CHINAPLAS 2022, seize the golden development opportunities of the market, seek new situations in the changing situation, and jointly explore the development path under the dual cycle of internal and external.

LITAI MACHINERY

The injection molding of the plastic thermoforming machine uses the thermophysical properties of the plastic to add the material from the hopper into the barrel. The outside of the barrel is heated by a heating ring to melt the material. The barrel is equipped with a screw driven by an external power motor to rotate. The material is gradually plasticized, melted and homogenized under the double action of screw shearing. When the screw rotates, the material will push the melted material to the head of the screw under the action of the friction force and shearing force of the falling groove. At the same time, the screw retreats under the reaction of the material, so that the head of the screw forms a storage space and completes the plasticization process. Then, under the action of the injection cylinder piston, the screw injects the molten material in the storage chamber through the nozzle at high speed and high pressure. In the cavity of the mold, after the molten material in the cavity has been pressure-maintained, cooled, solidified and shaped, the mold opens the mold under the action of the clamping mechanism, and the shaped product is ejected from the mold through the ejector device. 

A mold that uses plastic plates and sheets as raw materials to form some simpler plastic products. In the case of softening, it is deformed and attached to the cavity of the mold to obtain the desired molded product, which is mainly used in the production of some daily necessities, food and toy packaging products.

Due to the low pressure during molding, the mold material is mostly made of cast aluminum or non-metallic materials, and the structure is relatively simple.

Both thermosetting plastics and thermoplastics can be produced by injection molding machines. If thermosetting plastics are produced, the injection molding machine needs to be slightly modified. That is, the nozzle of the injection molding machine needs to be replaced, the nozzle is enlarged, and the backstop ring needs to be replaced. The backstop ring is used to prevent the plastic from flowing back.

Thermoset yellowstone is used very little these days, and I have hardly heard of it. A long time ago, more than ten years ago, I heard that the reflectors of our car lights use that thermosetting plastic, and some bread machines, ovens, etc., also use some thermosetting materials. But it is rarely used now, because many are replaced by thermoplastics.

Thermosetting plastics are cumbersome and expensive. I don't know the price of thermosetting material, but it is definitely more expensive than ordinary PP. Thermosetting plastics cannot be crushed and remolded. If there is a problem with a waste product, it is useless, you smash it, and it cannot be melted again. Thermoplastic, it can be crushed and reused, you can crush it and reuse it, and crush it and reuse it. There are also thermosetting materials, many of which require baking paint and electroplating on the surface. If there is waste, it may be scrapped.

Injection molding machines that produce thermoset materials are generally modified from very old injection molding machines. Because it is easy to produce and does not need debugging, it is heated by a heating rod mold and has no waterway, so it is usually an old machine to be modified to produce thermosetting plastic products.

Plastic molding processing equipment is developed on the basis of rubber machinery and metal die-casting machines. Plastic thermoforming machine is a kind of molding machine. The plastic or rubber raw material is placed in the mold, sandwiched between the upper and lower electric heating plates, and pressure is applied under the intelligent constant temperature of the electric heating plate to shape the raw materials.

Types of plastic molding machine processing equipment

Plastic Thermoforming Machine

There are only three types of plastic thermoforming methods for thermoforming machines, namely female mold forming, male mold forming and paired mold forming. The thermoforming machine should be able to repeat the thermoforming production cycle according to a certain program to make exactly the same product. There are many types of thermoforming machines, there are manual, semi-automatic and automatic thermoforming machines.

Thermoforming products are large in volume and small in quantity, so semi-automatic or manual thermoforming machines are suitable. On the contrary, if the volume of the product is small and the quantity is large, it is more appropriate to use an automatic thermoforming machine. It is suitable for the mixing, processing and batching test of chemical raw materials such as PVC and masterbatch in the rubber and plastic industries to detect whether the required color and quality are achieved, which can be used as the basis for batching before mass production in factories.

Plastic Injection Molding Machine

Plastic injection molding is a molding method of injection and molding, and its equipment is called plastic injection molding machine, or injection molding machine for short. Plastic injection molding machines are the main molding equipment for making thermoplastics and thermosets into various plastic products. Ordinary plastic injection molding machine refers to the most widely used single-screw or plunger horizontal, vertical or angle single-station injection molding machine for processing thermoplastics.

And other types of injection molding machines, such as thermosetting plastics, structural foaming, multi-component, reactive, exhausted and other injection molding machines, refer to some of the materials to be processed and the structural characteristics of the machine that are quite different from ordinary plastic injection molding machines. Injection molding machine. About 30% of the world's plastic raw materials are used for injection molding, and injection molding machines account for about 40% of the total output of plastic machinery, and have become an important part of the plastic processing industry and plastic machinery industry, which is the growth of plastic machinery products. One of the fastest models with the largest variety of specifications and the largest production quantity.

Plastic extruder

In the plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent equipment plastic extrusion molding machine is called the auxiliary machine. After more than 100 years of development, plastic extruders have been derived from the original single-screw, twin-screw, multi-screw, and even no-screw models. Plastic extruder (host) can be used with various plastic forming auxiliary machines such as pipe, film, holding material, monofilament, flat wire, packing belt, extruding mesh, plate (sheet) material, profiled material, granulation, cable coating and so on. Match to form various plastic extrusion molding production lines to produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used models in the plastic processing industry.

Plastic blow molding machine

Blow molding consists of two basic steps: first molding the parison, and then using compressed air (and a stretch rod) to radially inflate (and axially stretch) the parison to make it close to (stretch) blow molding Mould cavity, giving the shape and size of the cavity to the product, and cooling it.

Multilayer blow molding

There are two types of molding: co-extrusion blow molding and co-injection blow molding; stretch blow molding includes injection stretch blow molding and extrusion stretch blow molding. Stretch blow molding can be divided into one-step method and two-step method.

Presses and Transfer Molding Machines

Compression molding and transfer molding are the main molding methods for thermosets. The press for compression molding and the transfer molding machine for transfer molding are the main molding equipment for thermosetting plastics to make various plastic products. The function of the press is to apply pressure to the plastic through the plastic mold. If a fixed mold is used, it also has the function of opening and closing the mold and ejecting the product. The presses used for compression molding are divided into two categories: mechanical presses and hydraulic presses.
