1, Plastic injection molding machine
Plastic Injection Molding cup machine is a injection molding of a method, this equipment is called Plastic injection molding machine, referred to as injection molding machine. Plastic Injection molding machine is the thermoplastic and thermosetting plastics into a variety of plastic products, one of the main molding equipment. Ordinary Plastic injection molding machine is currently the most widely used, the processing of thermoplastic single screw or plunger horizontal, vertical or angular type of one-station injection molding machine. and other types of injection molding machine such as thermosetting plastic, structural foaming, multi-component, reactive, exhaust type injection molding machine, refers to the processing of materials and machine structure characteristics and ordinary plastic injection molding machine has a great difference in some injection molding machine. At 2011 around 30% of the world's plastic materials are used for injection molding, and injection molding machine accounted for about 40% of the total production of plastic machinery, and has become a plastic processing and plastic machinery industry, an important part of the plastic machinery products in the fastest growing, variety specifications, production of the largest number of machines in one.
2. Plastic Extruder
In plastic extrusion molding equipment, plastic extruder is usually referred to as the host, and its ancillary follow-up equipment plastic extrusion machine is called auxiliary machine. Plastic extruder After more than 100 years of development, has been derived from the original Single-screw twin-screw, multi-screw, and even no screw and many other models. Plastic extruder (host) can be used with tubing, film, holding material, monofilament, flat wire, packing belt, squeeze NET, plate (piece) material, profile, granulation, cable cladding and other plastic molding auxiliary machine matching, forming a variety of plastic extrusion production lines, production of various plastic products. Therefore, plastic extrusion machinery, whether now or in the future, are widely used in plastic processing industry one of the machine.
3, Plastic blow molding machine
Blow Molding Cup Making machine consists of these two basic steps: First molding the billet, and then using compressed air {with the tensile rod} to radial blown {and axial tensile} type billet, so that it snaps to {stretch} Blow mold cavity, the mold cavity shape and size of the product, and wait for cooling. According to the molding method of Parison, blow molding is divided into two kinds: extrusion blow molding and injection blow moulding. Extrusion blow molding equipment (especially the mold) its cost and energy consumption is low, this is one of its advantages, can be formed large volume containers and complex shapes of products, injection blow molding containers, have a higher dimensional accuracy, do not form joint seam, Usually will not produce the appearance of scrap, greatly saving material expenditure.
4. Multi-layer Blow moulding
Multi-layer blow molding of the production Cup machine, respectively, a total of extrusion blow molding and a total injection blow molding two, stretch blow molding has injection stretching blow molding and extrusion stretch blow molding two kinds. The tensile blow molding can be divided into one step and two steps. In one step, the molding, cooling, heating, stretching and blowing of the parison and the removal of the container are completed in one machine, the equipment cost and energy consumption is low, can be used for small batch production, in two steps, because the molding of the Parison and the reheating of the billet, stretching and blow molding respectively on two machines, high yield, suitable for mass production. Plastic blow molding machinery can be said that the plastic processing industry in the fastest growing, widely used in one of the machine, the evaluation is also high.
5, press and transfer molding machine
Plastic molding and transfer molding of the cup-making machine is the main molding method of thermosetting plastics. Mainly for the compression molding press and transfer Molding transfer molding machine is thermosetting plastic made of a variety of plastic products, the main molding equipment. The role of the press is through plastic mold on the plastic pressure, if the use of fixed-mode, but also has the opening and closing molds and the role of the ejector products. The presses for moulding are divided into two categories: motor presses and hydraulic presses. Because of the mechanical press of the manufacture, operation and repair are more complex than the hydraulic press, and not suitable for compacting large plastic parts, so gradually eliminated. Currently used presses are basically hydraulic presses. The pressure medium of hydraulic press usually has two kinds of oil and water, the former is widely used in medium and small-sized equipments. Transfer molding equipment can be used with the same hydraulic press molding, but also can be used for special transfer molding machine. The transfer molding machine is actually a double pressure hydraulic press with two hydraulic cylinders. According to its structure can be divided into upper and lower double pressure type and right angle type two kinds.
