The things you should know about mold test

        Record and analyze data as a need to modify molds and production conditions, and provide reference for future volume production. 1. Make the processing time longer to stabilize the melt temperature and hydraulic oil temperature. 2. If the size of all finished products is too large or too small to adjust the machine conditions, if the shrinkage rate is too high and the finished product appears to be insufficient shot, reference can also be made to increase the gate size. 3. If the size of the mold cavity and the door are correct, correct the machine conditions such as mold filling rate, mold temperature, and pressure of each part, and check certain molds. Whether the filling point is slower. 4. According to the situation of each mold cavity or the mold core shift, to be individually amended, perhaps try again to adjust the mold filling rate and mold temperature, in order to improve its uniformity.

5. Check and modify the failure of the injection machine, such as oil pump, oil valve, temperature controller, etc. will cause changes in processing conditions, even the perfect mold can not play a good work efficiency in poorly maintained machines. After reviewing all recorded values, retain a set of samples in order to check if the corrected samples have improved. Safekeeping of all records during sample testing, including various pressures in the processing cycle, melt and mold temperature, feed pipe temperature, injection action time, screw feed time, etc. In short, all future help should be preserved It is possible to successfully establish data for the same processing conditions in order to obtain products that meet quality standards.

            At present, the mold temperature is often neglected during the test of the mold, and the mold temperature is the least easy to grasp in the short-term mold test and future mass production. The incorrect mold temperature can affect the size, brightness, shrinkage, rhythm and under-charging of the sample. If you do not use a mold temperature controller to grasp future mass production, difficulties may arise.
