Polishing Of Pet Preform Mould

1 polished / skin texture Polishing of Pet Preform Mould is the last part of mold making. Polishing is directly reflected on the plastic parts, so this is the working side. Polishing can also help and complement the mold movement, especially for demolding. Often some molds are not smooth, because the lighting is not in place, the resistance is too great, even the white hat, the peeling is difficult, and the roof is cracked. 2 mold components With the assembly of the mold assembly machine, each part of each screw can not be mistaken, otherwise the consequences will be very serious, from the product defects to the production, serious damage is completely the mold, resulting in scrap. Therefore, the General Assembly must live very carefully. During the assembly process, especially in the mold cleaning work, especially the water, the screw holes must be blown clean inside the iron, otherwise the customer will be very angry. 3 hot runners or cold runners This has the least impact on mold quality, as hot runners are usually customer-specified brands, especially some large customers. Well-known foreign brands have done a good job in quality or after-sales service, so there is no problem with the overall quality. Only some domestic hot players have very different road quality. In order to save costs and strive for price advantage, individual small enterprises use some heat and conductive parts to fly, which is easy to issue. The main problem with cold runners is how to ensure the balance of injection, gate size, injection pressure, etc. 4 cooling water People with mold experience know how important cooling molds are. Due to the increase in prices and human wages, it is unthinkable to have no time to reduce the profit generated by a one-second injection cycle when producing products on a large scale. However, accelerating the production cycle will increase the mold temperature. If there is no effective control, the mold will not be formed due to overheating, and even the mold deformation will fail. Therefore, good water design is particularly important, including water distribution density, diameter, and interconnection. 5 mold maintenance Mold maintenance is mainly maintenance and maintenance during the production process. The mold is like a car, and if it is not repaired for a long time, it may lead to scrapping. Therefore, each mold must be fully maintained after use, especially to form part of the rust, the main part of the rust. Because the mold may be sleeping on the mold during installation or disassembly due to water in the production process, we must ensure that the mold is dry and then brushed with a layer of oil.
