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.
