The performance and quality of plastics directly affect the quality of plastic parts, especially for many of the strength, flexibility and the use of the special requirements of the plastic parts are particularly important. Therefore, in order to carry out mass production, should be used to conduct a comprehensive inspection of the performance and quality of plastic, including:
Whether the varieties, specifications and grades of the raw materials used in the test are consistent with the required parameters.
Check the appearance of raw materials, including the color of raw materials, particle size and uniformity, etc..
Check the process performance of raw materials, such as melt index, fluidity, thermal performance, shrinkage, water content, etc..
