일반적인 플라스틱 재료 문제에 대한 실질적인 답변

11636 질문
Q
MP insufficient mixing
A
insufficient mixing is caused by improper screw design; increasing the mixing section is key
Processing Machinery MP insufficient mixing screw mixing section kneading block side feeding
Q
MP poor fatigue resistance
A
poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is key
Molds & Tooling MP fatigue resistance crosslinking degree molecular weight stress concentration
Q
MP length out of tolerance
A
length out of tolerance is caused by unstable shrinkage rate; precise shrinkage compensation is key
Molds & Tooling MP length out of tolerance shrinkage rate mold compensation full cooling
Q
MP obvious surface color difference
A
color difference is caused by uneven dispersion and orientation; masterbatch method and stable processing are key
Injection Molding MP color difference color masterbatch dispersion pigment orientation temperature stability
Q
MP vacuum section material overflow
A
material overflow is caused by low melt viscosity; lowering temperature and adding a baffle are key
Extrusion & Post MP vacuum section overflow melt viscosity temperature lowering vent baffle
Q
MP surface orange peel texture
A
orange peel texture is caused by rapid cooling and solidification; raising mold temperature and holding are key
Injection Molding MP orange peel texture mold temperature holding pressure surface solidification
Q
MP stress cracking
A
stress cracking is caused by stress-accelerated chemical attack; annealing and high MW are key
Production & Quality MP stress cracking environmental stress annealing high molecular weight
Q
MP severe internal stress concentration
A
internal stress is caused by fast injection and uneven cooling; reducing speed, uniform cooling and annealing are key
Injection Molding MP internal stress orientation stress annealing uniform cooling
Q
MP surface dense pitting
A
pitting is caused by raw material impurities and mold damage; pure raw material and mold maintenance are key
Extrusion & Post MP surface pitting impurity particles mold repair raw material purity
Q
MP difficult purging
A
difficult purging is caused by MP strong adhesion; PE flushing and lowering temperature are key
Processing Machinery MP difficult purging adhesion PE flushing special purging compound
