How do injection mold factories solve the problem of product whitening?
During the injection molding process, injection mold factories often encounter the problem of whitening. When many injection mold factories encounter this problem, they have to use mold release agents to temporarily solve it in order to rush the goods. However, the use of mold release agents will directly affect the appearance of the product, and even excessive use will destroy the plasticity of the product, thereby reducing the future use effect of the product. In addition, the use of mold release agents also increases production costs. Therefore, injection mold factories should start with the ejection structure of the mold to solve the whitening phenomenon of the product.
In order to completely solve the problem of product whitening, injection mold factories must check whether the ejector pin can be added to the whitening part, whether there is a bone position that is not smooth, and if there is a bone position and there is a fire pattern that is not clean, it is easy to cause whitening. Z. Another reason is that the draft angle of a part of the product is not enough. If this is the reason, rework is necessary. Only with a sufficient draft angle can the whitening phenomenon be cut off, otherwise no matter how you save smoothness or add ejectors, the whitening can be completely solved.
