Tips for injection molding of nylon cable ties Apr 10, 2020
1. Pay attention to mold temperature If the lower temperature of the heat-resistant and abrasion-resistant nylon cable ties in the production, the faster the material cooling rate in the mold cavity, so that it can greatly shorten the take-out time of the product and improve the efficiency of the molding operation. However, if the temperature is too low, it will easily cause the appearance of the ...
