What is injection molding?
Plastic injection molding is refers to the plastic particles melt into liquid, and then to squeeze the liquid into the cavity of the mould.Injected into the shape of the plastic will keep the mold cavity and cavity wall surface texture.After setting the optimization of injection molding and cooling stage, the curing ejection molding plastic products, mass products manufactured in this cycle the processing steps.Molding cycle according to different product size and product design, molding resin, can be from a few seconds to a few minutes.
The advantage of injection molding
- Selection of thousands of kinds of plastic injection molding materials, these materials have all kinds of engineering properties and appearance.
- In view of the mass production, injection molding is more economic.If it is a small batch production, we suggest that according to the product characteristics adopts CNC, complex mode shape or Milling-turned Machining and other production methods.
- A mould can injection thousands of products
- Surface quality of the products have all kinds of polishing and texture effect to choose from
- For a product contain a variety of different types of plastic, we will use a package plastic injection technology.The injection molding technology is suitable for light weight, corrosion resistance of the product.
Mould manufacturing
Such as aluminum alloy 7075, hardening tool steel P20 and fully hardened tool steel H13, is the most commonly used material in the mould manufacturing.Choose to use what kind of material manufacture of moulds, depends on how you plan to make several large quantities of products.
Aluminum alloy mold
Aluminum alloy mold is one of the most rapid and economic die.Aluminum alloy hardness is weaker, suitable for small batch of mold production.And for mass production, very strong corrosion resin, there is a thin blade or bone or product structure, in order to strong and durable it is better to use hardness strong metal mold.
Steel mold
Relative to other moulds, steel moulds are very strong and durable, and long processing cycle.Steel mould is suitable for mass production or injection of those of higher plastic aluminum alloy mold corrosion and wear.
- Pre hardened tool steels used for mass production of more than 100000.Depends on the different plastic raw materials and products of the complexity of the structure, YUYAO GOOD PLASTIC HARDWARE use P20 Or steel NAK80 annealing.
- Hardened tool steel is one of the most durable material, up to millions of times of injection molding production.H13 hardened steel is very suitable for mass production or injection of wear resistant engineering grade plastic.
