POM short shot

Short shot = racing against solidification.

Molds & Tooling POM；short shot；solidification；injection speed；mold temperature

POM '2079851475616104452 flash

Flash of low-viscosity material = pressure and gaps.

Injection Molding POM；flash；low viscosity；clamping

POM sink marks and voids

POM feeding = gate freeze time management.

Molds & Tooling POM；sink marks；voids；gate freeze；holding pressure

POM weld line weak strength

POM weld lines = racing against crystallization speed.

Molding Process POM；weld line；crystallization；melt temperature；gate

POM surface streaks/silver streaks

For POM silver streaks, check degradation first, then moisture.

Material Drying POM；silver streaks；streaks；degradation；drying

POM sticking to mold

Molds & Tooling POM；mold sticking；crystallization；mold temperature；draft

POM warpage

Warpage = a lesson in balancing crystallization shrinkage.

Molds & Tooling POM；warpage；crystallization；mold temperature；holding pressure

POM product dimensions too small (post-shrinkage)

POM dimensions = only the dimensions after 24 hours count.

Molds & Tooling POM；post-shrinkage；dimension；crystallization；measurement aging

POM trapped air burning

Burning = check both venting and temperature.

Molds & Tooling POM；trapped air；burning；venting；decomposition

POM mold deposits (mold fouling)

POM mold fouling = a high-frequency maintenance item, and venting is the line of defense.

Molds & Tooling POM；mold fouling；deposition；venting；maintenance
