Basics of The Injection Molding

Here are Some Typical Complications.

Burned or Scorched Parts: Melt temperature may be too high. Polymer may be becoming trapped and degrading in the injection nozzle. Cycle time may be too long allowing the resin to overheat.

Warpage of Parts: Uneven surface temperature of the molds. Non-uniform wall thickness of mold design.

Surface Imperfections: Melt temperature may be too high causing resin decomposition and gas evolution (bubbles). Excessive moisture in the resin. Low pressure causing incomplete filling of mold.

Incomplete Cavity Filling: Injection stroke may be too small for mold (ie. not enough resin is being injected). Injection speed may be too slow causing freezing before mold is filled.

All of this just are the basics of the injection molding. And for the injection molding, we have to focus on the process to make the high quality products.
