How to deal with the problem of fusion line?
Reason analysis: From the perspective of plastics, the melting line is essentially caused by the incomplete melting of two plastic flow fronts. Solution: To eliminate or reduce the melting line, plastics must have low viscosity, high temperature, sufficient pressure and enough time to melt completely. Usually, in the case of good exhaust, accelerating the filling and feeding speed and increasing the pressure as soon as possible after the combination of two plastic flow fronts will help to solve the melting line problem.
