“Flash is one of the most common reasons injection molded parts get scrapped,” Bill explained. Flash occurs when excess material collects around the perimeter of a part, much like crusty batter around the edges of a waffle. Causes for flash vary. Flash often occurs when too much material i...
Delamination is a defect in injection molded parts where the plastic resin fails to properly bond or set, resulting in peelable surface layers. It occurs when there is a lack of adhesion between different layers of the molded part. This defect can compromise the integrity of the plastic part ...
Why is burn marks a big issue with injection molded parts? Also called gas traps and dieseling, burn marks are quite literally as the name implies: burns. This is much different from, say, brown streaks and swirls that you might find on the surface of a freshly molded plastic component. ...
Anyone who has ever designed a product to be injection molded likely learned that small design changes can significantly impact the cost, time frame, and overall success of the project. This is also true for additive manufacturing projects. Being aware of a few common mistakes that might be ...

The mold caused by abnormal injection cycle. (5) equipment problem: Increasing the plasticizing capacity of the injection press; Make the injection cycle normal; (6) cooling conditions: The parts are cooled too long in the mold to avoid contraction from the outside and shorten the coo...
Custom dunnage often uses injection-molded plastic, corrugated plastic, or a combination of industrial solid plastics and foams to provide separation, protection, and shock absorption. Due to its bespoke nature, custom dunnage is one of the most expensive dunnage materials compared to other materials...
