Why do injection molds need manual provincial polishing!

Injection molding products transform design concepts into real objects through mold injection molding and injection molding processing, in which injection molds play a decisive role. Injection mold processing has many processes. Today, the injection mold manufacturer will introduce the mold preservation and polishing process to you.

After the mold is processed, the CNC machining knife pattern or discharge spark pattern will be left on the mold surface. At this time, it is necessary to save the mold and polish the mold. Saving on mold polishing can improve the smoothness of injection molded products, and the mirror spark machine can also do this.

However, generally speaking, injection molding manufacturers will manually save the mold polishing, and repeat the same seemingly simple actions every day. In fact, it is very stressful. First of all, saving mold polishing has two purposes: 1. In order to improve the surface finish of the mold and make the produced product more beautiful 2. In order to better release the mold, improve efficiency and prevent the product from sticking to the mold, if the mold surface roughness is poor , is easy to stick to the mold. In order to produce better and more beautiful products and improve production efficiency, it is very important to do a good job of polishing to save molds.

The mirror surface effect can be achieved by using mirror spark machining parts. Both mirror spark machine and manual die saving can improve the smoothness of the die. The difference is that the mirror spark machine is mainly used for precision machining of the surface of the complex mold cavity, which can shorten the production cycle, but the processing cost is also higher than that of the ordinary spark machine.

Manual die saving is used to save some parts that cannot be done by mirror spark machine. Manual die cutting, high yield and long cycle time. In the early stages of processing, manual polishing is very rigorous.

Each polishing technician must carefully complete the operation, and must check each processing procedure.
