POM

 

POM(Polyoxymethylene) Has Moderate Fluidity And A Fast Crystallization Speed. During The Molding Process, The Mold Temperature And Cooling Rate Must Be Controlled To Avoid Surface Defects Or Internal Shrinkage Marks. Overheating And Decomposition To Produce Gas Must Be Prevented. The Shrinkage Rate Is High After Demolding. The Mold Design And Process Adjustment Can Ensure Dimensional Stability. Pay Attention To Exhaust During Processing To Avoid Porosity Problems.

Homopolymer

POM

Polyoxymethylene (POM) Is Easy To Decompose At High Temperatures, And The Processing Temperature Needs To Be Strictly Controlled. It Has A Fast Crystallization Speed And A High Shrinkage Rate. It Is Easy To Shrink In Size Or Have A Concave Surface. It Has Low Water Absorption. Proper Drying Helps To Improve Fluidity. The Mold Exhaust Design Needs To Be Reasonable To Avoid Defects Caused By Residual Gas.

General Homopolymer POM Properties

Copolymer

POM

Copolyoxymethylene (Com) Has Good Fluidity, Can Easily Fill Complex Molds, And Has High Molding Efficiency; It Has Low Shrinkage, And The Finished Product Size Is Relatively Stable, Which Is Suitable For Precision Parts Manufacturing. It Has Strong Heat Resistance, Is Not Easy To Decompose At High Temperatures, And Can Adapt To Longer Processing Cycles. It Is Slightly Sticky, So Pay Attention To The Demoulding Slope Or Surface Treatment To Reduce The Risk Of Sticking. The Overall Process Control Is Relatively Simple And Suitable For Mass Production.
