PP Glass Fiber Reinforced Application
Problem Phenomenon
【Problem Phenomenon】Need PP to be lightweight and increase rigidity, glass fiber reinforcement evaluation
Cause Analysis
Glass fiber reinforced PP greatly improves rigidity, strength and heat resistance while maintaining light weight; used in automotive structural parts, home appliance frames, and industrial components; shrinkage is reduced; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solution
Select glass fiber PP for structural parts; LFT long glass fiber has better performance; select fiber content according to rigidity requirements; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PP glass fiber reinforcement is light and rigid, the main force of automotive structural parts; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
