The Influence of Plastic Mold Quality on Injection Molding Production

The purpose of mold design and manufacturing is for the mass production of injection parts with high efficiency and high quality, to produce high-quality plastic parts, the first mold is good, a good set of plastic molds is not just a good look, want to do a set of high-quality, high level, high precision plastic molds, from the following aspects.

1. The smoothness of the injection mold surface

The polishing of the mold surface is very important, which is one of the most important links to determine the success or failure of mold manufacturing. The surface of the mold is not smooth enough, its surface is uneven, and the surface of the plastic parts injected will have skin lines and sand grains. Generally, the polishing surface into a mirror is good, in addition to the choice of mold steel, grinding personnel, time, technology will have an impact on the polishing mirror effect, requiring a professional mold polishing master, experience to be particularly rich in order to accurately grasp the polishing time, to ensure the effect of mold mirror polishing.

2. Accuracy of mold

The precision of the mold determines the dimensional accuracy of the plastic parts, mold manufacturing must first have the conditions of high-precision measurement, such as quadratic detector, three-dimensional detector and other detection instruments, using the object imaging principle to accurately calculate the size and spatial position of the object, can detect the difference of 0.02mm, accurate measurement of product size and injection volume.

3. Fit degree of mold production

Although the mold industry has certain operating standards, the mold and injection molding of different mold manufacturers will have small differences, such as mold opening and injection molding are not the same manufacturer, due to the different mechanical equipment and production methods of various manufacturers, there will be risks in production, affecting product quality and production efficiency, in order to reduce this risk, generally choose to open mold and injection molding in the same manufacturer is better. From mold opening to injection molding manufacturers can control themselves, and problems can be solved in time.
