High Precision Machining Actuator Housing,
this part is an adjustable spring seat, which is used on the chassis system, the carried Die Casting criterion is Grade GB-CT5, this part is produced as cast.
In addition, the part required surface finish of electrophoresis coating, in order to improve the appearance condition of the part, making all the parts more consistent, we choose to develop corresponding trim mold for removing the injection gate, slag trap, overflow gate and flash around the parting line.
But this part maybe have the quality issue of Bad surface.
Features: during the filling process due to temperature of liquid or alloy mold temperature is too low, in similar to the small spots under pressure under the condition of the casting surface formed like distribution area.
Causes
1. When filling, the metal is dispersed into concentrated droplets, and the wall is impacted at high speed.
2. The gate thickness is too small.
Exclusion measures
1, the correct design of gating system, to avoid metal liquid splash, improve exhaust conditions, to avoid liquid flow into excessive gas, reduce the gate speed and improve the mold temperature.
2. Properly adjust the gate thickness.
