The Biggest Feature Of HDPE In Injection Molding Is Its Good Fluidity And Wide Processing Temperature Range. It Can Quickly Fill Complex Molds In The Molten State And Is Suitable For Producing Thin-Walled Or Finely Structured Products. The Cooling And Solidification Speed Is Fast, Which Can Shorten The Production Cycle, But The Cooling Shrinkage Rate Is High, And It Is Easy To Have Shrinkage Marks Or Deformation, Which Needs To Be Improved By Adjusting The Holding Time And Pressure.
HDPE Is Sensitive To Mold Temperature During Injection Molding. Properly Increasing The Mold Temperature Can Reduce Internal Stress And Surface Defects, But Too High A Temperature May Cause Demolding Difficulties. Its Material Has Good Toughness But Weak Rigidity. It Is Often Used To Manufacture Lightweight Products Such As Daily Containers And Toys That Do Not Require High Strength. The Mold Design Needs To Reserve Shrinkage Allowance And Optimize The Demolding Angle To Ensure Stable Quality Of The Finished Product.

HDPE
HDPE (High-Density Polyethylene) Has Good Corrosion Resistance And Flexibility. It Is Often Used In The Injection Molding Production Of Various Containers, Daily Necessities And Other Plastic Products. It Is Heated And Melted And Then Injected Into The Mold For Rapid Molding, Which Is Suitable For Efficient Mass Production.
