Plastic mold factory is how to deal with white spots, white?

Plastic mold manufacturer how to deal with white lace. Generally do not understand the industry's first consider the gas. Why do you say that? Because this is a lot of people who don't understand the injection all know method, but this approach has a fault, is a waste. In addition to gas, there is no other solution? So how is the white lace?
white lace is modified polyethylene and organic glass of a kind of special injection molding defects, appear on the edge of the near the parting surface parts. White is made up of many perpendicular to the flow direction stretch orientation of molecules and the collection of small distance between them. White edge direction have polymer connection phase, so the white is not a crack. Under the proper heating has the potential to stretch after the state of molecular return to natural curly, make white fade.
plastic mold manufacturer's solution:
in the process of production, we should pay attention to keep the agreement template parting surface closely, especially the area around the cavity, must be under the real enough clamping force, to avoid the mould of longitudinal and lateral expansion.
lower injection pressure, injection time, injection volume and molecular orientation.
in the mold white painted oily demoulding agent, surface heat transfer in the position of the difficulty, high temperature for longer. On the other hand, it makes the inhibition of white lace and it possible to reduce the appearance of white edge.
improve the mold design. For example, if the mould made of elastic deformation of materials, can strengthen the cavity wall and bottom plate mechanical bearing capacity, can withstand the impact of high pressure injection and working temperature has risen sharply, the white edge prone to give higher temperature compensation, change the direction of material flow, make the flux distribution inside the cavity is reasonable.
