Best season for production of perforated plastic sheet
In North China, spring is coming and the weather is getting warmer and warmer. From March to May is the best production season for perforated plastic sheets,because the temperature keeps between 17 to 25 centi-degree. In this kind of situation,the shrink and grow of the plastic sheet will be the least,so we can keep the exact size of the finished perforated plastic sheets.
As a reliable manufacturer of perforated plastic products,we have tested the change of the size affected by the temp. in the production. If you have strict requirement on the size, the temp. is absolutely an important factor that you have to pay attention to. The change of the temp of 1-2 centi-degree. will bring about 0.1mm change in the size.
In June, the temp. will grow to more than 30 centi-degree,the perforated plastic products will shrink greatly when they are used in a place with lower temp.
