Injection Molding

Improving measures when the matte surface of PVC injection molded parts is serious

Under normal circumstances, the serious problem of dullness on the surface of PVC injection molded parts (the gloss is not enough) is usually solved. Most of them are solved by increasing the temperature of the melt and the mold. Appropriately increasing the melt back pressure can also make the surface of the injection molded parts [...]

Extending the flow channel to reduce the injection mark and vibration mark of PC injection molded parts

Sometimes because the flow channel is too long, the melt at the forefront is cooled too much, which leads to injection moldings with radial lines and shock lines, and the performance of PC materials in this regard is particularly prominent, followed by transparent PVC. This is why sometimes the melt temperature has risen so high [...]

The reasons and solutions for shrinkage problems in PC plastic parts

According to the principle of material solidification, the reason for the formation of internal shrinkage holes and surface shrinkage of the injection molded part is that the melt needs to continuously shrink during the cooling process. When the shrinkage is concentrated to the position where the injection molded part is finally solidified, and the melt [...]

The reasons for the lack of edges and corners in the production of POM plastic parts

POM are easily decomposed by heat, and there is a troublesome problem. When the raw materials are decomposed by heat, impurities will be generated in the dead corner of the mold. For a long time, the accumulation of more and more, the dead corner will be filled with impurities, resulting in lack of injection molding [...]

8 ways to eliminate the black spots on transparent plastic parts or light-colored plastic parts

When producing transparent plastic parts, it often happens that the injection molding takes more than ten hours, or even a few days, and the black spots cannot be removed. Not only waste a lot of production time, but also waste a lot of the company's raw materials. Therefore, how to prevent the problem of many [...]

Injection machine adjusting techniques to prevent gas lines when fast filling is required

Difficult to fill raw materials and injection parts with larger and thinner sizes usually need to be filled with a faster injection speed to fill the cavity. However, many injection-molded parts will produce obvious ridges or gas lines around the gate, and problems such as scorching after injection of the injection parts. Especially when spraying [...]

The reasons and elimination of tiny pits on the bright plastic parts surface

When pitting occurs, it is easy to think about whether the mold is rusty. However, upon closer inspection, it was found that the mold was still quite bright and there were no small marks. After increasing the melt temperature and back pressure to improve the quality of the melt, the situation will improve, but sometimes [...]

Adjusting method for severely flashing of injection parts

Most of the junior and intermediate injection molding technicians only use the first-level injection method for injection molding production. Many problems such as overflow and shrinkage in production can be solved with only one-stage injection adjustment. As a result, it gradually became a habit that has not changed for many years. When there are some [...]

Important process to ensure the surface brightness of injection molded parts

In the production of injection molding, the appearance quality of the surface of the injection molded parts, such as matt color, insufficient brightness and insufficient transparency, is often encountered. In addition to the mold cavity surface must first have a good brightness, the main reason for this problem in production is that during the injection [...]
