Production Definition Of Rotational Moulding Plastic Products

In recent years, with the rapid development of plastics industry and the constant progress of general and engineering plastics in strength and precision, the application scope of plastic products is also expanding, such as: household appliances, instrumentation, construction equipment, automobile industry, daily hardware and many other fields, the proportion of plastic products is increasing rapidly. A well-designed plastic can often replace many traditional metal pieces. The trend of plastics in industrial products and daily-use products is increasing.Rotational Moulding Plastic Products

The general definition of mold: In the industrial production, with a variety of pressure machine and the special tools installed on the press, through the pressure of metal or non-metallic materials to produce the required shape of the parts or products, this special tool collectively known as the mold.Rotational Moulding Plastic Products

Injection process Description: Mold is a tool for the production of plastic products. It consists of several sets of parts, the combination of which has a molded cavity. Injection molding, mold clamping on the injection molding machine, melt plastic is injected into the molding cavity, and cooling in the cavity stereotypes, and then the upper and lower mold separation, after the top of the system will be products from the mold cavity top out of the mould, the final mold closed to the next injection molding, the entire injection process is cycle.Rotational Moulding Plastic Products

Injection molding is the most commonly used method in plastic processing. The method is suitable for all thermoplastic and partially thermosetting plastics, the number of plastic products produced by other molding methods behind, as one of the main tools of injection molding process of injection mold, in the quality of precision, manufacturing cycle and injection molding process of production efficiency, and so on, directly affect the quality of products, Production, cost and product updates, but also determine the enterprise in the market competition in the responsiveness and speed.Rotational Moulding Plastic Products

Hot Runner Mold: This type of mold structure and fine water mouth is roughly the same, the biggest difference is that the runner is in one or more of the constant temperature heat runner plate and nozzle, no cold material stripping, runner and gate directly in the product, so the flow path does not need demoulding, this system is also known as the water-free system, can save raw materials, suitable for raw materials, Products require a higher situation, design and processing difficulties, mold cost is higher.Rotational Moulding Plastic Products
