Our company mainly customizes various styles of plastic bathtub moulds . The following is a detailed description of the manufacturing process of plastic bathtub moulds :
【mould steel】Plastic bathtub mould steel cavity & core is generally made of materials above P20, and needs high hardness mould steel. The hardness of this type of steel reaches 25-30 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 injection moulding machine models of plastic bathtub moulds are all 500T-1000T equipment.
【mould ejection system】The ejector of the plastic bathtub mould uses the ejector pin and the valve, so the material used for the ejector pin is very important, generally SKD61 is used.
【mould cooling system】For plastic bathtub moulds , the cooling quality of the mould determines the output of plastic bathtub moulds and therefore the unit price of the product. Generally, the moulding delivery time of this mould is about 35 to 45 seconds.
【mould gate system】The gates of plastic bathtub moulds all use the big hot runner gates , and there are also the most high-quality needle valve hot runner gates. This 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, it is easy to have poor air vent, especially for plastic bathtub moulds , because it is a high-speed production, so air vent must be done well.
【mould steel hardness treatment】The mould steel hardness treatment is also very important, and the surface of the plastic bathtub mould mould will be electroplated.
【mould life】The life of the plastic bathtub mould is determined by the material. Generally, P20 can reach more than 300,000 shots.
【mould transportation method】Before the plastic bathtub 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 45-65 days.
