How to solve the shrinking problem of thick wall plastic parts-surface shrinkage

The shrinkage problems of hard plastic parts (surface shrinkage and internal shrinkage) are mostly due to defects caused by insufficient melt supplement when the thicker parts are cooled. It is often the case that increasing the pressure, increasing the gate, and extending the injection time, the shrinkage problem cannot be solved. Among the commonly used [...]

That process to improve the dimensional accuracy of plastic injection parts

In the production of certain important injection parts that require relatively accurate dimensions, the allowable tolerance range of the size of each plastic part is very small, and even requires only 0.01 to 0.02 mm of tolerance. In the production process, the main factor that usually affects the dimensional accuracy of injection parts is the [...]

How is the color matching pigments influence the strength of injection parts

1, Strength defects caused by color matching Because the colors are mixed with the raw materials in the heating cylinder of the injection molding machine after melting, unlike the toners that have been mixed with the raw materials in the feeder in advance, the color matching of the colors will easily cause the mixing of [...]

You have to pay more attention in color calibration and production of purple PVC parts

The injection of purple PVC plastic parts is relatively troublesome, and the color cannot be checked immediately after forming, because the color is definitely wrong and the deviation is very large. This is because such injection-molded parts will continue to change color after being produced for a period of time, and they become more purple, [...]

Top 10 Influencing factors that cause color instability in injection part production

In injection molding production, sometimes the color changes once every few days, or even a few color deviations within a day. There are many factors that cause color instability. The main factors that will cause color instability are listed below to improve the control during production. 1, The temperature of the injection machine is unstable. [...]

How to eliminate the color deviation of injection plastic parts by adjusting the temperature

The color of the injection molded part will be changed by the melt temperature during plasticization. Usually the temperature difference is about 10 ℃, you can already see the color deviation of the injection molded parts. Therefore, when the deviation between the color of the injection molded part and the sample is not very large, [...]

The Solutions and adjustment techniques when the color mixing of injection parts is serious

In general, when color mixing occurs in injection molded parts, appropriately increase the back pressure of the melt or increase the melt temperature up to 10°C ~15 °C, or add some diffusion oil for color matching and increase the amount of secondary recycled materials to improve the mixing operation. If the screw speed is too [...]

Must To Know The Settings Of Injection And Pressure On Produce Plastic Parts

Injection and holding pressure have the same place, but also have a big difference. At the operational level, injection and holding pressure have the following similarities. Unless the injection servo valve is used, the injection directional valve is open during injection and pressure running, and will not be closed during it (of course, it will [...]

Pay Attention To 13 Process That Affect The Quality Of Injection Molding

1, The barrel temperature (raw material temperature) The thickness of raw materials and products. In general, the barrel temperature should be set at 10°C to 20°C above the rated melting temperature of the raw materials. Amorphous raw materials such as PS and ABS do not have a definite melting point, so the barrel temperature should [...]
