Plastic Parts

Customized plastic parts: This is a set of hard plastic molds in a set of overmolding molds, this set is also set of beer hardware, the product is relatively simple. Solutions to injection molding problems 6. Water Wave Effect

reason:

The injection molded parts encountered poor cooling conditions during the inflow process, the injection speed was too low, or the melt temperature was too low.

To produce water ripples. Another reason is that the plastic is rapidly cooled while entering, and it cannot move smoothly to press the plastic against the mold.

The wall, and the plastic enters in the form of radiation, and the surface after cooling makes it like a water ripple/finger pattern.

Improve methods:

a) Plastic

. Replace with a higher flow level

b) Mould

. Increase gate diameter

. Increase the diameter of the runner

c) Injection molding machine conditions

. Increase Wang Su speed

. Increase the temperature and plastic pressure (first stage)

. Increase plastic melt temperature

. Increase mold temperature

Note: Use mold temperature control machine and remember to add mold heat insulation board. For customized plastic parts, please contact Shenzhen Qunxingwang Mould Technology Co., Ltd., China: qxwmould_co_ltd@163.com
