An Injection moulding machine is the main moulding equipment that uses thermoplastic or moulded plastic moulds to produce plastic products of various shapes. It is widely used.
1. Manufacture of various plastic products
Consumer electronics shell: such as mobile phone shells, tablet PC shells, headphone shells and so on. These products need precise size and good appearance quality. The injection moulding machine can produce shells with complex appearance and internal structure quickly and efficiently according to the designed mould shape.
Automotive parts: including automotive interior parts (such as dashboard panels, door panels, seat adjustment buttons, etc.) and some small exterior parts (such as rear-view mirror housings, air intake grills, etc.). Automotive interior parts require good tactility, high strength and beautiful appearance. The interior parts produced by injection moulding machines can be made with different additives to achieve various textures.
Daily necessities: like plastic tableware (e.g. bowls, plates, spoons, etc.), toys, stationery (e.g. pens, eraser housings, etc.), and a variety of household items (e.g. bins, storage boxes, etc.). Taking toys as an example, injection moulding machines can produce toys in a wide variety of shapes and colours. Whether they are simple block toys or electric toys with complex action structures, they can all be achieved by injection moulding. For plastic tableware, injection moulding machines can ensure that the hygiene standard and mechanical properties of the products meet the requirements of people's daily use.
Industrial fittings: such as a variety of plastic pipe fittings, valves, motor housings, tool handles and so on. In the industrial field, these plastic fittings need to have certain strength, corrosion resistance and dimensional accuracy. Plastic pipe fittings produced by injection moulding machines can be used to convey various liquids or gases, and their sealing and corrosion resistance can be achieved by selecting suitable plastic materials and injection moulding processes. The motor casing requires good heat dissipation and mechanical protection, and the injection moulding machine can manufacture products to meet these requirements.
2. Processing and moulding test of plastic materials
Material performance testing: In the research and development of new plastic materials, injection moulding machines can be used to process new materials into standard test specimens to test the material's physical properties (e.g. tensile strength, bending strength, impact strength, etc.) and thermal properties (e.g. heat distortion temperature, Vicat softening point, etc.). By changing the injection parameters (e.g. temperature, pressure, speed, etc.), it is possible to study the effect of these parameters on the properties of the material after moulding, so as to optimise the formulation and processing of the material.
Mould testing and optimisation: For newly designed injection moulds, the injection moulding machine can be used to carry out a trial mould. During the mould trial, problems in the mould design and manufacturing process can be found, such as whether the gate position is reasonable, whether the demoulding is smooth, whether the cavity filling is uniform, etc. By constantly adjusting the mould and injection parameters, the mould reaches the best working condition, providing reliable technical support for mass production.
3. Small batch production and customised production of plastic products
Small batch production: For some plastic products with small market demand or fast product replacement, the injection moulding machine can carry out small batch production. For example, limited edition toys for special festivals and customised gifts for promotional activities. The injection moulding machine can complete the production of small-lot products in a shorter time to meet the diversified needs of the market.
Customised production: With the increase in consumer demand for personalised products, injection moulding machines can be used to customise the production of plastic products. For example, consumers can customise products with special shapes, colours or logos according to their design requirements. By changing moulds and adjusting process parameters, injection moulding machines can quickly respond to this customised demand and produce products that meet customer requirements.
