Plastic forming machine processing equipment is opened on the basis of rubber machinery and metal die-casting machine. Since the emergence of polymer injection moulding technology and simple moulding equipment in the 1970s, as an industry, it was not opened quickly until the 1930s. Plastic moulding equipment has gradually been commercialized. Injection moulding and extrusion moulding have become industrialized processing methods. Blow moulding is the third largest plastic moulding method after injection moulding and extrusion, and it is also a kind of plastic moulding method with faster opening.

Plastic injection moulding is a method of both injection and moulding. Its equipment is called plastic injection moulding machine, or injection moulding machine for short. Plastic injection moulding machine is the primary moulding equipment for making thermoplastics and thermosetting plastics into various plastic products. The general plastic injection moulding machine refers to the horizontal, vertical or angular single-station injection moulding machine with single screw or plunger for processing thermoplastic materials, which is widely used.

Other types of injection moulding machines, such as thermosetting plastics, structural foaming, multi-component, reactive and exhaust injection moulding machines, refer to some injection moulding machines whose structural characteristics are quite different from those of ordinary plastic injection moulding machines. About 30% of plastic raw materials are used for injection moulding, and injection moulding machine accounts for 40% of the total output of plastic machinery. It has become an important part of plastic processing industry and plastic machinery industry. It is one of the machines with fast growth, standardized types and large output.

Plastic extruder

In the plastic extrusion equipment, the plastic extruder is generally called the main machine, and its supporting follow-up equipment, the plastic extrusion molding machine is called the auxiliary machine. After more than 100 years of opening, plastic extruders have been derived from single screw, twin screw, multi-screw and even no screw. Plastic extruder (main machine) can match various plastic forming auxiliary machines, such as pipe, film, holding material, single wire, flat wire, packing belt, extrusion net, sheet (sheet) material, profiled material, granulation, cable cladding, etc., to form various plastic extrusion forming production lines and produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used machines in the plastic processing industry.

Plastic Blow Molding Machine

Blow moulding consists of two basic processes: first forming the billet, then using compressed air (and stretching rod) to blow the billet radially (and axially) to make it close to (stretch) the blow moulding cavity, giving the shape and standard of the cavity to the product, and cooling it.

Multi-layer blow molding

There are two kinds of blow moulding: co-extrusion blow moulding and co-injection blow moulding, while stretch blow moulding has two kinds: injection stretch blow moulding and extrusion stretch blow moulding. Drawing blow moulding can be divided into one-step method and two-step method.

Press and transfer moulding machine

Compression and transfer moulding are the primary moulding methods of thermosetting plastics. Press and transfer moulding machine for compression moulding are the primary moulding equipment for thermosetting plastics to be made into various plastic products. The effect of the press is to exert pressure on the plastic through the plastic mould. If the fixed mould is selected, it also has the effect of opening and closing the mould and ejecting the product. Presses used for compression moulding are divided into two categories: motor press and hydraulic press. Because the manufacture, operation and repair of the motor press are more messy than the hydraulic press, and it is not suitable for pressing large plastic parts, so it is gradually screened. The press used is essentially hydraulic. Pressure medium of hydraulic press generally includes oil and water, the former is widely used in small and medium-sized equipment. Transfer moulding equipment can be used in the same hydraulic press as compression moulding, or special transfer moulding machine. The transfer moulding machine is actually a double-pressure hydraulic press with two hydraulic cylinders. According to its structure, it can be divided into upper and lower double pressure type and right angle type.

Thermoforming machine

Thermoforming machine plastic thermoforming methods only need three kinds, i. e. negative, positive and opposite moulding. Thermoforming machinery should be able to repeat the production cycle of thermoforming in accordance with relative procedures to produce the same products. There are many types of thermoforming machines, including manual, semi-automatic and automatic thermoforming machines. The volume of thermoforming products is large and the quantity is small. 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 choose the automatic thermoforming machine.
