Found this kind of phenomenon should be timely and equipment manufacturers. 10, if the main parts have not found what problem, after cleaning the parts should wear protective oil. Screw packages tied up and hanging in ventilated place. Normal injection molding machine injection molding machine factory factory, general won't appear the quality problem of the big. The use of equipment unit, the important is through the equipment acceptance test, well test data record, in case of equipment maintenance in the future when as reference in inspection.
