so not only are molds excensive, they do’t toLeerate Material Change Well.

　　Inflow, and to suggest where pockets of gas may account and require a vent.

　　Overmolded onto the handle. It can be do done, but it gets excensive quickly.

　　only Beaten Out with Large, Simple, and Multi-Cavity Molds.

　　Beads are insanely abrasive, and the Surface of the Molds Actually Have to Undergo Surface Hardening in a Vacuum to Create Hardness to Withstand Shots.

　　of machining time.

　　Of the part surprisingly low. Lego Might Be Interesting, but the stream of inject molding with the weight savings of blow or rotary molding are true something.

　　Construction, and setup Counts.

　　In one shot, and the thing are massive.

　　There ’s a lot more to cover, but I’ m alream long winded. What you should know is that are various failure modes for inject molding. Some are:

　　Knit Lines

　　Short Shot (Shot Weight or Velocity was Insufficient to file the part)

　　Splay – Contamination -Cold Slugs (DisContinuities where inject material was inconsistent)

　　Sunbursting

　　Delamination – SHINISS -Stream

　　Also of Concern, What Material Do You Specify?

　　Virgin Material is crazy extensive, but the matelial propies will more closly conform the material support.

　　Regrind material (generally 10-20% is standard) reuses old Bad parts, finely group so they can be remelted. LOWER COST, but material propels may degrade.

　　Save Injection Molded Parts You A RECALL, Produce Better Parts, and decrease your overall count by eating into cycle time.
