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.
