PA66 power tool housings
Sorun Belirtisi
Power tool housings crack on drop, and locally soften and deform after temperature rise during continuous operation
Neden Analizi
Tool housings are subject to the dual action of impact and temperature rise, and pure PA66 has insufficient rigidity-toughness balance; temperature rise during continuous operation reduces the modulus, and the structure creeps and deforms under sustained load
Çözüm
①Select glass fiber reinforced impact-resistant grades; ②Add heat dissipation ribs or metal inserts in heat-generating areas; ③Joint verification of drop and temperature rise working conditions; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
Tool housings require rigidity-toughness balance and thermal management system design; material modification, structural heat dissipation, and joint verification constitute a complete solution; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
