The advantages of plastic mold injection molding method are fast production speed, high efficiency, operation can be automated, variety of colors, shapes can be from simple to complex, size can be from large to small, and the product size is accurate, the product is easy to update, and can be shaped Complicated parts, injection molding is suitable for mass production and molding processing fields such as products with complex shapes
Generally speaking, there are three main aspects in evaluating the performance of plastic products:
First, the appearance quality, including completeness, color, gloss;
Second, the accuracy between size and relative position, that is, size accuracy and position accuracy;
Third, the mechanical properties, chemical properties, electrical properties, etc. corresponding to the purpose, that is, functional
Therefore, if there is a problem in any of the above three aspects, it will lead to the production and expansion of product defects.
The plastic mold injection molding process involves many factors such as mold design, mold manufacturing, raw material characteristics and raw material pretreatment methods, molding process, injection molding machine operation, etc., and is closely related to processing environmental conditions, product cooling time, and post-processing technology. Complex processing flow. Therefore, the quality of the product is not only determined by the injection accuracy and measurement accuracy of the injection molding machine, or only by the pros and cons of the mold design and the accuracy level of the mold processing.
