The production requirements of plastic trash can mold are very high, generally using environmentally friendly pp materials,Can hit a bright surface and then do film printing and other processing, become a high-grade trash can,But it is not easy to make a good trash can. First of all, the quality of the mold should be well controlled, including the mold design, mold assembly, the selection of hot flow channels and cold flow channels, and so on.Leiao molding tells you how to better control the problems in the process of plastic mold:
1. Mold assembly
Mold assembly is just like the assembly of machines, each part, each screw can not make mistakes, otherwise the consequences will be quite serious, light will lead to product defects, affect the production, heavy is complete damage to the mold, resulting in scrap.So the assembly work must be very meticulous.In the assembly process, we should pay attention to the cleaning of the mold, especially the water, screw holes, must blow clean the iron scraps inside, otherwise the customer is very angry, the consequences are also very serious.
2.The hot runner or the cold runner
In fact, this has the least impact on the quality of the mold, because the heat flow channel is generally the designated brand, especially some big customers.Foreign well-known brands regardless of the quality or after-sales service are very in place, so the quality generally will not have a big problem.Just some domestic hot flow channel brand on the quality is very different. Individual small enterprises in order to save costs, to strive for the price advantage, with some unreliable heating and conduction accessories, it is easy to have problems. And the main problem of the cold flow channel is how to ensure the injection balance, pouring size, injection pressure and so on.
3. Cooling waterways
Anyone who has mold experience knows how important cooling is for a mold.Due to the increase of raw materials and workers’ wages, the profit of each second reduction during mass production is unimaginable, but accelerating the production cycle will lead to the rise of mold temperature,If it is not effectively controlled, the mold is too hot to form, and even lead to the mold deformation and scrap.Therefore, excellent waterway design is particularly important, including the waterway arrangement density, diameter and so on.
4. Maintenance of the mold
Mold maintenance is mainly the maintenance and maintenance in the production process. The mold is just like a car. If it is not used for a long time, it may lead to the rejection of the mold.So each mold should be fully maintained, especially the molding part of the rust, the main action parts of the rust.Because the mold needs to be connected water in the production process, there may be water to the mold in the process of installation or disassembly, so we must ensure that the mold is dry, and then brush a layer of oil to protect.
