Hello everyone, thanks for attention. We’ve discussed about the temperature control system earlier, now we are going to talk about the mold venting information in following 11 articles, from the...

The gas in the injection mold includes not only the air in the cavity, but also the air in the gate and the decomposition gas generated by the plastic melt, and the steam which caused by plastic in...

During the injection molding process, the front end of the slight ribs may be air trapped and plastic burnt, and also cause the molded part may become black and carbonized. The mechanism of air...

The air trapping in cavity is usually in the following places: 1. Thin-wall structure cavity, the end of melt flow; 2. The junction of two or more melts; 3. The last area where the melt in the cavity...

The exhaust system should ensure that the gas in the cavity is smoothly discharged, and also prevent the material from entering and exhausting channels from causing flashing of the product or blockage...

The exhaust system of plastic molds is also very important, if the product has air trapping or exhaust system is not suitable will have a big impact on injection molding production and product...

The exhaust slot on the parting surface is easy to clean and processing, also not easy to be blocked, and has a good exhaust effect, it is the main area where the gas is exhausted, so the exhaust from...

There are a large amount of gas in the main and sub channel, these gas are discharged through the pull rod (push rod) during injection processing, a part of gas come out from exhaust slot on parting...
