Automotive Mould Manufacturers

Our company mainly customizes various styles of auto parts moulds . The following is a detailed description of the manufacturing process of auto parts moulds :
【mould steel】The cavity & core of the auto parts mould steel is generally made of materials above 718 and NAK80, and it is necessary to use high-hardness mould steel. The hardness of this type of steel reaches 35 degrees. If customers need better materials, we will purchase mould steel according to customer requirements.
【mould design software】The company uses UG, CAD, PRO/E and mould flow software, etc.
【mould processing equipment】Mainly are: radial drilling machine, flying knife grinder, gantry CNC milling, engraving machine tool, deep hole drilling machine tool, EDM machine tool, Haitian injection moulding machine for mould trial. The models of injection moulding machines for auto parts moulds are all 500T-2000T equipment.
【mould ejection system】The ejector of the auto parts mould uses the ejector pin plus the ejector block, etc., so the material used for the ejector pin is very critical, generally SKD61 is used.
【mould cooling system】For auto parts moulds , the cooling quality of the moulds determines the output of auto parts moulds and therefore the unit price of the products. Generally, the moulding delivery time of this mould is about 60 to 180 seconds.
【mould gate system】The gates of auto parts moulds all use hot runners to feed glue, and there are also needle valve hot runner gates that require the highest quality, which depends on the customer's choice.
【mould air vent system】mould air vent is also very important. If the air vent don't make good, the product is prone to poor air vent, especially for auto parts moulds, because it is a high-speed production and the air vent must be done well.
【mould steel hardness treatment】The mould steel hardness treatment is also very important, and the surface of the auto parts mould will be electroplated.
【mould life】The life of the auto parts mould is determined by the material, generally 718 can reach more than 500,000 shots.
【mould transportation method】Before the auto parts mould is shipped, the surface of the mould will be treated with anti-rust material, and the mould will be locked with a safety lock, and then wrapped in film.
【mould production delivery time】The delivery time of small and medium-sized moulds is about 45-180 days.
