The purpose of mold design and manufacture is to produce high-efficiency and high-quality mass production of injection molded parts. To produce high-quality plastic parts, firstly, the mold must be good. Quality, high-level, high-precision plastic molds can be viewed from the following aspects

Smoothness of the injection surface of the mold

The polishing of the mold surface is very important, which is one of the most important links that determines the success or failure of mold manufacturing. The surface of the mold is not smooth enough, and its surface is uneven, and the surface of the injection molded plastic product will have skin textures and sand particles. Generally, it is better to polish the surface into a mirror surface. In addition to the choice of mold steel, the polishing personnel, time, and technology will affect the polishing effect. A professional mold polishing master is required, and the experience must be particularly rich to accurately grasp the polishing time to ensure that The effect of the mold after mirror polishing.

Precision of the mold

The accuracy of the mold determines the dimensional accuracy of the plastic parts. Mold manufacturing must first have high-precision measurement conditions, such as two-dimensional detectors, three-dimensional detectors and other testing instruments. The object imaging principle is used to accurately calculate the size and spatial position of the object. Detect the difference of 0.02mm and accurately measure the product size and injection volume.

Fitting degree of mold production

Although the mold industry has certain operating standards, there will be slight differences in the molds and injection molding of different mold manufacturers. For example, mold opening and injection molding are not the same manufacturer. Due to the different mechanical equipment and production methods of each manufacturer, there will be risks in production. , Which affects product quality and production efficiency. In order to reduce this risk, it is generally better to choose the same manufacturer for mold opening and injection molding. From mold opening to injection molding manufacturers can control themselves, and problems can be solved in time.
