Plastic Dustbin Mould have very high requirements. Generally, environmental protection PP materials are mostly used, which can produce a bright surface and then do film printing and other treatments. It becomes a high-end trash can, but it is not necessary to make a good trash can. It's easy. First of all, the quality of the mold must be controlled, including mold design, mold assembly, hot runner and cold runner selection, etc. As the saying goes, the layman sees the excitement and the expert is the doorway. If we want to become a professional expert, we must understand the trash can. How to better control the problems of the mold, mainly as follows:

（1） Mold assembly

Mold assembly is just like assembling a machine. Every component and every screw cannot be wrong, otherwise the consequences will be very serious, from the slightest to the product defect, affecting the production, and the other to completely damaging the mold and causing scrap. Therefore, the assembly work must be very meticulous. In the assembly process, pay special 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.

（2）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. Because the quality and after-sales service of foreign well-known brands are very well done, 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.

（3）cooling water circuit

Anyone who has mold experience knows how important cooling is to a mold. Due to the increase in special prices and labor wages, it is impossible to imagine the profit that does not reduce the attention cycle of one second when referring to the production of products. However, while accelerating the production cycle, the temperature of the mold will rise. If it is not effectively controlled, the mold will be too hot to form, and even cause the mold to deform and fail. Therefore, a good waterway design is particularly important, including the arrangement density, diameter, thought of the previous links, and so on.

（4） Mold maintenance

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, it may sleep on the mold during the installation or disassembly process, so make sure the mold is dry, and then brush a layer of oil protection.
