Our company mainly making various styles of plastic chair moulds. The following is a detailed description of the manufacturing process of plastic chair moulds :
【mould steel】Plastic chair mould
steel cavity & core is generally made of materials above P20 and 718H, and 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 mouldflow 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 mould machine for chiar moulds normally need about 1000 Tons.
【mould ejection system】The mould ejector pins must be made of SKD61 high-quality material. The ejection of the plastic chair mould needs to be connected with the ejection structure of the injection moulding machine so that it 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 chair moulds , the cooling quality of the mould determines the output of the plastic chair mould and therefore the unit price of the product.
【mould gate system】The gate of the injection chair mould is generally designed under the back of the seat cushion, and this position can hide the defects of the gate well.
【mould air vent System】mould air vent is also very important. If the air vent don't make good, it is easy to cause poor air vent, especially for chair moulds. Because the number of mould points is large, 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 chair mould depends on the material. Generally, the hardness of P20 is about 25 degrees, the life of this mould is basically 200,000 shots. The hardness of 718 material is about 30 degrees, and the mould life of this material is basically at 400,000 shots. The better the material, the longer the mould life.
【mould transportation method】Before the injection moulding chair 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, then wrapped in film.and final with wooden package.
【mould production delivery time】The delivery time of small and medium-sized moulds is about 65 days.
The above is a simple introduction of injection chair moulds production of Dunhai mould Factory. Welcome to inquire.
