Injection Molding

Insufficient strength of PBT injection molded parts (unreinforced)
Sorun Belirtisi
Pure PBT injection molded products easily break when stressed, and the strength does not meet the requirements.
Neden Analizi
Pure PBT resin itself has limited strength and modulus (tensile strength about 55MPa), no reinforcing materials such as glass fiber are added, and there is internal stress.
Çözüm
Switch to glass fiber reinforced grades (30%GF tensile strength can reach more than 130MPa); optimize the molding parameters to reduce internal stress.
Temel Çıkarım
PBT engineering applications usually require glass fiber reinforcement to meet strength requirements.
