Taizhou Huangyan Rongwei Plastic Mould Co., Ltd. is located in Huangyan, the hometown of moulds in China. We have the most advanced mold manufacturing equipment and the most qualified trained employees. dustbin mould is one of our main products. Let's introduce how the mold is made.
Mold assembly is just like assembling a machine. Every part and every screw cannot be wrong, otherwise the consequences will be quite serious, from the slightest to the product defect, affecting the production, and the other to completely damaging the mold and causing scrap. So the assembly work must be very meticulous. During the assembly process, pay attention to the cleaning of the mold, especially the waterway and screw holes. The iron filings must be blown out, otherwise the customer will be very angry and the consequences will be very serious.
Hot runner or cold runner, this actually has the least impact on mold quality, because hot runners are generally designated brands, especially some large customers. The quality and after-sales service of well-known foreign brands are all done very well, so there are generally no major problems in quality. It's just that the quality of some domestic hot runner brands is quite different. In order to save costs and strive for price advantages, individual small companies use unreliable heating and conduction accessories, which are prone to problems. The main problem of cold runner is how to ensure injection balance, gate size, injection pressure and so on.
Cooling water, anyone who has mold experience knows how important cooling is to a mold. Due to the increase in raw materials and wages of workers, in mass production, the profit brought by every one second of time reduction is unimaginable, but speeding up the production cycle will also cause the mold temperature to rise, if not effectively controlled If it is too hot, the mold will not be able to form due to too much heat, and even cause the mold to deform and fail. Therefore, a good waterway design is particularly important, including the arrangement density and diameter of the waterway.
Mold maintenance is mainly maintenance and maintenance during the production process. The mold is like a car, if it is not used for a long time without maintenance, it may cause the mold to be scrapped. Therefore, every time the mold is used, a comprehensive maintenance must be carried out, especially the rust prevention of the forming part and the rust prevention of the main moving parts. Because the mold needs to receive water during the production process, water may get onto the mold during the installation or disassembly process, so make sure that the mold is dry, and then brush a layer of oil protection.
