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 Skal forbedres ved at justere holdingstid og tryk .
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 Skimmeldesign skal reserverer krympningsgodtgørelse og optimere den demoldende vinkel for at sikre en stabil kvalitet af det færdige produkt .
