What cause Glass Fiber Streaks?

Cause:

Based on the length of the glass fiber and the front direction and matching relationship between the melting flow during the flow. And the flow speed and cooling

The speed  is poorly arranged by the glass and iron, some vertical and some oblique standing, so the floating surface of the glass domain (glass fiber distribution

The present situation of unevenness, in addition to the poor appearance, will reduce the engineering structure of injection plastic parts.

Improvement method:

a) Plastic

.. Replace short glass fiber materials

..Change glass beaded material

b) Mold

.. Change the size of injection gate

C) Injection Molding machine parameter

.. Increase injection speed

.. Increase the Mold temperature

.. Increase the plastic melt temperature

.. Increase the holding pressure time

.. Increase holding pressure

.. Check whether the temperature of injection nozzle is enough.
