The manufacturing of plastic stools is an injection molding process. The selection of raw materials can be determined according to demand! Injection process
I. Temperature control
⒈Barrel temperature: The temperature to be controlled in the injection molding process includes barrel temperature, nozzle temperature and mold temperature.
⒉ Nozzle temperature: The nozzle temperature is usually slightly lower than the maximum temperature of the barrel. This is to prevent the "salting" of the melt in the straight-through nozzle.
⒊ Mold temperature: The mold temperature has a great impact on the intrinsic performance and apparent quality of the product.
Second, pressure control The pressure in the injection molding process includes two kinds of plasticizing pressure and injection pressure, which directly affect the plasticization of plastics and product quality.
⒈Plasticizing pressure: (back pressure) When a screw-type injection machine is used, the pressure on the top of the screw when the screw rotates and retracts is called plasticizing pressure, also known as back pressure.
⒉Injection pressure: In the current production, the injection pressure of almost all injection machines is based on the pressure exerted on the plastic by the top of the plunger or screw (converted from the oil pressure).
