There are different tuyeres every year, but I have never seen so many tuyeres and so fierce transformation in manufacturing industry of this year!
Mr. Yan of Jinhua was not moved when the wind of masks started blowing. When the tuyere of the melt-blown-cloth comes quietly, he didnāt start the business; But when his old business of injection molding helmets began to be popular, he was finally moved.
When the mold and injection molding machine finally arrived in his factory, Mr. Yan started production but find various problems during the production. T There were always black spots on his plastic helmet whose main material was ABS. He adjusted it for two consecutive nights and found a lot of problems, which can hardly be solved.
In fact, in view of Mr. Yan's problems, we have shared many times in the previous articles of Taili Plastic Machinery. The key point is to determine what causes the black spots.
1. Non-mold injecting to eliminate the problem of storage section
To deal with this problem, the first step is to use the non-mold injecting method, move the injection seat back, and turn on the motor for non-mold injection, and observe whether there are black spots in the material. If there are spots, the problem may lie in the impurities in the raw materials, the three small parts of the screw or other parts of the barrel. Further inspection can be made to determine the key part with impurities.
2. Adjusting process parameters
In the injection process, the causes of black spots are as follows. Firstly, the sol temperature is so high that the raw materials decompose. Secondly, when the back pressure is so high that the melt part decompose large shear force. Thirdly, the injection speed is too high, resulting in air trapping. We can further adjust the parameters to determine the cause.
3. Mold factor
This factor is often ignored by the adjusting technicians. For the black spots caused by the high temperature friction of the mold and the residual melting material in the runner, the location of the black spots should be carefully observed. Generally, the black spots on the product surface are mostly caused by mold problems, so we should further investigate the mold.
Mr. Yan finally found that the cause lies in the mould. At that time. However, he had wasted too much time checking the process and materials. In fact, it's really hard to be a fair goer. In order to succeed, we should do the right thing, not the simple thing.
Taili Plastic Machinery always keeps in mind that what a good injection molding machine factory should do is to help improving the capacity and boosting the profits, rather than offer the similar products the customers need. This is also what Taili Plastic Machinery keeps doing.
