Designing a manufacturing tool involves multiple stages. Teams can follow this workflow: Throughout this tooling design process, clear communication between designers, manufacturers, and end users helps manage expectations on cost, timing, and performance.

Injection molding defects refer to undesirable phenomena in the appearance, dimensions, structure, or performance of plastic parts during the injection molding process, caused by factors such as materials, processes, equipment, or operations. These defects may manifest as surface roughness, dimensional inaccuracies, internal voids, or inclusions within the plastic parts. Injection molding defects not only affect …

This type of defect typically manifests as numerous very small blister within the finished product, often accompanied by silver streaks. When observing the product externally, these blister typically appear as circular bright spots. For precision plastic injection molding products with waterproof performance requirements, even a tiny blister can lead to the entire product being returned …
