Raw Material Inspection
First and foremost, we carefully examine the incoming raw materials. This involves checking their physical properties like hardness, color, and particle size. Chemical analysis is also carried out to confirm that the materials match the specified grades and have no impurities. For example, when using plastic pellets for injection molding, we test their melt flow index to ensure they will flow properly during the molding process. Only materials that pass these strict inspections are allowed to enter the production line.
