Industry knowledge development
Our company mainly customizes various styles of plastic stool moulds . The following is a detailed description of the manufacturing process of plastic stool moulds :
【mould steel】Plastic stool mould steel cavity & core is generally made of P20 and above 718H materials. 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 stool moulds are all large-scale equipment around 500T-1000T.
【mould ejection system】The ejector pins of the mould must be made of SKD61 high-quality material. The ejection of the plastic stool mould needs to be connected with the ejection structure of the injection moulding machine, so that the ejection of the mould can be reset smoothly. And an electronic limit switch needs to be added to ensure the normal production of the mould.
【mould cooling system】For plastic stool moulds , the cooling quality of the mould determines the output of the plastic stool mould and therefore the unit price of the product.
【mould gate system】The gate of the plastic stool mould is generally designed in the middle hole, so as to avoid the defects caused by the gate.
【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 stool moulds . Because there are many points in this mould, there will be many fusion wiring positions, so air vent it matters.
【mould steel hardness treatment】The mould steel hardness treatment is also very important, because this is directly related to the service life of the mould. The mould analysis surface needs laser quenching, the depth of the hardness is 2mm, and the surface can reach about 50 degrees.
【mould life】The life of the plastic stool mould depends on the material. Generally, the hardness of P20 is about 25 degrees and the life of this mould is basically 200,000 shots. While the hardness of 718 material is about 30 degrees and the life is basically 400,000 shots. The better the material, the longer the mould life.
【mould transportation method】Before the plastic stool 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.
