These points must be noted when injection molding tooling

Recently, a lot of partners have asked what points must be paid attention to when injection molding, today Shanghai Pronounced to take a look at what points must be paid attention to when injection molding!

1、The shrinkage coefficient of each material is different, the injection mold needs to have a reasonable shrinkage rate.

2, the injection mold needs to have enough rigidity, otherwise the mold will be closed when the pressure will be deformed, causing "flying edge.

3、If the product is ejected while the mold is open, the ejector page of the injection molding machine can be set.

4, we need to choose a reasonable method of demoulding and a reasonable location and number of ejector bars to ensure that the product is not damaged in the ejection process.

5、The cooling in the injection molding tool is related to the product size, shape, plastic nature, holding time and other factors.

6、The injection mold should choose a reasonable exhaust position and its amount of control. Otherwise bow| up plastic injection is not enough and the product "lack of material"

7, the injection mold and injection molding machine fixed way to be reasonable, to be reliable and solid, to prevent the mold to close the position and lead to|accidents. And to disassemble easily.

8, injection mold in the case of no return spring with the moving part of the mold - together with the injection molding machine to move, is the mold ejector plate and the machine ejector rod connected together (commonly known as strong top).

9, injection channel should be selected reasonably, so that the material can evenly reach each - and there should be enough storage capacity to ensure that the plastic in the shrinkage process to replenish the plastic.

10, injection mold material post-treatment is not required, because: plastic soft, do not need any special requirements such as hardness, and heat treatment process may cause mold deformation.

11, injection mold cavity roughness level need to be able to "mirror level", otherwise the product is difficult to demold, the product ejected if the force will lead to damage to the product.
