Q
EMA Extrusion Screen Pack Frequent Clogging
A
Screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are key
Extrusion & Post EMA extrusion screen clogging gel particles stepped screens automatic screen changer
Q
EMA Processing Moisture Causes Silver Streaks
A
Silver streaks are caused by moisture vaporization and stretching; drying and venting are the main countermeasures
Material Drying EMA injection silver streaks moisture drying venting back pressure
Q
EMA '2079851475616104452 Cold Slug Marks
A
Cold slug marks are caused by solidified residual material in the nozzle; increasing nozzle temperature and cold slug well design are key
Injection Molding EMA injection cold slug marks nozzle temperature cold slug well injection pressure
Q
EMA Extruded Film Wrinkling During Winding
A
Film wrinkling is caused by tension fluctuation and uneven thickness; automatic tension control and uniformization are key
Extrusion & Post EMA film winding wrinkling tension control thickness uniformity guide roller parallelism
Q
EMA '2079851475616104452 Flow Marks
A
Flow marks are caused by unstable injection front and rapid cooling; multi-stage injection and high mold temperature are key
Injection Molding EMA injection flow marks injection speed mold temperature gate area
Q
EMA '2079851475616104452 Sink Marks
A
Sink marks are caused by insufficient holding and wall thickness differences; high-pressure holding and multiple gates are the core countermeasures
Injection Molding EMA injection sink marks holding pressure wall thickness difference gate design
Q
EMA Performance Decay After Repeated Processing
A
Performance decay after multiple processing is caused by thermo-mechanical degradation; limiting regrind and supplementing antioxidants are key
Production & Quality EMA recycling performance decay antioxidant supplementation thermal degradation shear degradation
Q
EMA '2079851475616104452 Multi-Cavity Filling Imbalance
A
Multi-cavity filling imbalance is caused by runner design; balanced runners and mold flow analysis are key
Injection Molding EMA injection multi-cavity balance runner design gate size mold flow analysis
Q
EMA Injection Molded Product Ejector Whitening
A
Q
EMA Extrusion Unstable Feeding
A
Unstable feeding is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core
Extrusion & Post EMA feeding bridging loss-in-weight feeder pelletizing feeding screw
