Analysis and solution of white spots in injection molding

In the process of injection molding, there are often some problems, among which the white spot problem is a more common one. White spots refer to the irregular white markings on the surface of the product during injection molding, which seriously affect the quality and appearance of the product. So, what is the cause of white spots in injection molding? How to solve it?


There are many reasons for the appearance of white spots in injection molding, including materials, equipment, technology and so on. For example, there may be impurities or undesirable substances in the material, resulting in white spots on the surface of the product; Aging or improper maintenance of equipment, resulting in white spots on the surface of the product; There may be unreasonable temperature, pressure and other parameters in the process, leading to white spots on the surface of the product.

For the problem of white spots in injection molding, we can take the following measures to solve it:


1. Improve material quality: Choose materials with stable and uniform quality to avoid impurities or undesirable substances in the materials.

2. Update the device: Check and maintain the device regularly to ensure the normal operation of the device and avoid white spots on the product surface caused by aging or improper maintenance of the device.

3.. Adjust the process parameters: adjust the process parameters according to the actual situation to ensure that the temperature, pressure and other parameters are reasonable to avoid white spots on the product surface.

In addition to the above measures, other methods can be used to solve the problem of white spots in injection molding, such as the use of spraying materials, coating tape and other methods to cover white spots. However, it should be noted that these methods are only suitable for minor white spot problems. For serious white spot problems, more professional methods are needed to solve them.
