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 [...]

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 [...]

3 key process parameters affecting the strength of injection molded parts

1, Increasing the injection pressure can improve the tensile strength of PP injection molded parts. PP material is more elastic than other rigid plastics. Therefore, the density of injection molded parts will increase with the increase of pressure. This feature is relatively obvious. When the density of plastic parts increases, its tensile strength will naturally [...]

How to control the assembly and disassembly force of injection parts by adjusting the machine

Two injection molded parts that can be assembled and disassembled are commonly known as male parts and female parts. When the injection pressure and injection time of the male part increase, or the injection pressure and injection time of the female part decrease, the outer diameter of the male part increases, the inner diameter of [...]

The problems that should be noted in injection molding of transparent thick-walled plastic parts

Due to special functions, some thick-walled transparent injection parts are often encountered during injection molding. Because to performance reasons, these plastic parts use PC as the raw material, and the average wall thickness More than 6mm, the maximum wall thickness exceeds 12mm. For such plastic parts, two problems often occur during injection molding, one is [...]
