Plastic Injection Molded Parts Quality Control Procedures We Follow:
1. Machine Inspection (On-The-Spot Inspection)
Parts are initially inspected directly out of our molding machine. Our machine operators are trained to identify and rectify the following defects:
1.1.Sink marks that form when the outer plastic shell hardens before the internal plastic has had an opportunity to cool.
1.2.Short shots caused when there is an inadequate amount of plastic material to fill the mold.
1.3.Burn marks caused by trapped compressed air during the molding process.
1.4.Flash marks, which is the excess plastic that extends from the end of the molded part
2. Finishing Station Inspection
Parts at the finishing station are inspected for consistent finishes and textures prior to silkscreen or pad printing.
3. Quality Control Department Inspection
Finished parts undergo one final inspection to ensure tolerances are met for every part. Optical projector and digital calipers measure for part accuracy to within =/-.005mm.
Why You Should Also Consider Importing Injection Molds to Your Own Country for Mass Production?
Not ALL plastic injection molds are necessarily cheaper to stay in China for mass part production, otherwise China would not have become the world’s largest mold exporter.
The following conditions will justify your bringing the molds to your own country for mass production:
If the plastic part or product you intend to develop and produce falls under none of the above conditions, the chances are that it’s better to leave the injection molds in China for production.
