Plastic injection moulding process

plastic injection moulding process: First, check whether the masterbatch resin species matching, measurement accuracy, followed by adjusting the temperature or speed of the machine, there are still problems such as should masterbatch manufacturer. Same masterbatch, the resin and formulation of different injection moulding machine injection out why the product color shades? This is often the plastic injection moulding machine causes. Different plastic injection moulding machine for the manufacture, use or maintenance of the status of the different time,Cheap Nike Shoes resulting in differences in the state machinery, especially the heating elements and the barrel close to the degree of difference, so that the dispersion of masterbatch in the barrel in the state are not the same The above phenomenon will appear. For another brand of resin, the masterbatch and the same formula, the color has changed, why? Different grades of resin density and melt index are different, so there will be differences of resin performance, compatibility with the masterbatch will be a difference, and thus the color change occurs, in general, as long as its density and melt index does not vary large, then the color difference will not be too large, you can adjust the amount of masterbatch to a more positive colors.China Wholesale Masterbatch during storage occurred in the phenomenon of pigment migration will affect the quality of products? Some masterbatch pigment content (or dye) is high,Wholesale Sunglasses in this case, the migration phenomenon is normal. In particular, the masterbatch is added dye, the migration phenomenon will be serious. But this does not affect the quality of the products, as injection into a masterbatch products, the pigments in the product in a normal color concentration.
