If you are a manufacturer of UPVC pipe fittings, you may often face problems such as rough and matte pipe fitting surfaces, difficulty in injection molding under high injection pressure, failure to mold, scorching and black lines on surface, and poor demoulding. In most cases, the problem can be improved by adjusting the machine parameters. There are also some reasons for the PVC raw material compounds. There may be some defects in your raw material formula. Some UPVC granule suppliers will reduce the amount of stabilizers and lubricants added in order to save costs, which will lead to difficulty in injection molding.
Since our engineers have more than 20 years of experience and are very familiar with the injection molding process, you can come for consultation if you encounter such problems. At the same time, if you use our UPVC pellets, the production process will be smoother.
Our PVC provide you with a larger processing window, which means it is more convenient for your production and processing. For example, the processing temperature range of starPVC COMPOUND can reach 160-188 degrees Celsius, you can get the finished pipe fittings without adjusting too many machine parameters.
