Plastic trash can mold production requirement is very high, generally adopt environmental protection PP materials, can play bright surface and then do sticker printing processing, become a good trash can, but to make a good trash can is not easy, first mold to control good quality, including mold design, mold assembly, hot flow and cold flow and so on, etc., Leo mold tell you how to better control the plastic mold problems in the process of processing?
01 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 detailed. 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.
02 Cooling water
Anyone who has mold experience knows how important cooling is for a mold. Due to the growth of raw materials and workers’ wages, in mass production, each second to reduce the profit is unimaginable, but speed up the production cycle at the same time will lead to mold temperature rise, if not effective control will make the mold because too hot to molding, and even lead to mold deformation failure scrap. Therefore, excellent waterway design is particularly important, including the waterway arrangement density, diameter and so on.
03 The flow channel is hot or cold
In fact, this has little impact on the quality of the mold, because the heat flow channel is generally the designated brand, especially some big customers. Foreign famous 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 fight 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.
04 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. Therefore, after the use of the mold, all aspects of maintenance should be carried out, especially the rust of the molding part and the rust of the main action parts. 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.
Leiao mold is good at manufacturing plastic molds, plastic products, home appliance molds, daily necessities molds, industrial molds and so on. Leiao mold has a full range of CNC machining center, large gantry milling machine, vertical milling machine, CNC engraving machine, EDM machine, wire cutting machine, etc., with cad / cam / cae design technology, making us have the ability to manufacture large size mold, complex mold, multiple cavity mold, thin wall mold and high precision mold.
