Influence of plastic mold quality on injection molding production

The purpose of mold design and manufacture is to mass-produce injection parts with high efficiency and high quality. To produce high-quality plastic parts, the first step is to have a good mold. A good plastic mold is not only good in appearance, but also if you want to make a high-quality plastic mold. Quality, high-level, high-precision plastic molds, from the following aspects:

The smoothness of the injection surface of the mold

The polishing of the mold surface is very important, which is one of the very important links that determines the success or failure of mold manufacturing. The surface of the mold is not smooth enough, the surface is uneven, and the surface of the injection molded plastic product will have skin lines and sand grains. In general, it is better to polish the surface into a mirror surface. In addition to the choice of mold steel, polishing personnel, time and technology will have an impact on the polishing mirror effect. Professional mold polishing masters are required, and they must have rich experience to accurately grasp the polishing time. The effect after mirror polishing of the mold.

Precision of the mold

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

The fit of the upper mold of the mold

Although there are certain operating standards in the mold industry, there will be slight differences between 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. , affecting 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.
