Technical Problem 1 from Fiberglass Compression Molding:cavities unfully filled


 Technical Problem 1 from Fiberglass Compression Molding:cavities unfully filled

Description 1:Not fully filled at the edge of Fiberglass Compression Mold
1.Reason:Insufficient feeding Fiberglass SMC material---Solution:Increase the quantity of feeding
2.Reason:Molding temperature is too high--Solution:Decrease molding temperature.
3.Reason:The closing time of SMC Pressure Machine is too long, and the Fiberglass SMC is solidified before the mold is filled.--Solution:Shorten closing time.
4.Reason:Molding pressure is too low--Solution:Increase molding pressure.
5.Reason:Feeding area is too small--Solution:Increase feeding area

Description 2:Not fully filled in small area on the edge of the Fiberglass Compression Mold
1.Reason:Insufficient feeding--Solution:Increase the quantity of feeding.
2.Reason:Material loss before mold closing--Solution:More careful discharge.
3.Reason:The distance between upper and lower cavities is too large or the fitting length is too short.--Solution:Reduce the fitting clearance and increase the fitting length.If the defect is small,increase the molding temperature or add excess Fiberglass SMC material.

Description 3:Although the entire edge is full filled but some areas are not full filled
1.Reason:Insufficient feeding--Solution:Increase the quantity of feeding.
2.Reason:Air failed to drain--Solution:Improve feeding method.
3.Reason:Air in the blind hole cannot be discharged--Solution:Use three-half mold structure or allow air to be discharged from the ejector pins.If the defect is small to increase the pressure.
