Injection molding flash is a visible defect on plastic parts. Flash is the small plastic layer popping from the mold where two mold halves meet. Interestingly, flash can also occur in other places where there is a gap, plastic material overflow, movable cores and...
Geometric Dimensioning and Tolerancing (GD&T) establishes a system to provide precise design details and communications. It allows engineers and manufacturers to handle dimensional variations and geometrical irregularities. The US military began developing...
Injection-molded parts usually measure a wall thickness between 1 and 5 mm. The proper thickness selection depends on three main factors: plastic material properties, functional requirements, and mold flow performance. The part performance requires you to keep the...
Punching and stamping are two sheet metal fabrication processes, heavily used in metalwork projects. Punching is for creating holes of different shapes, whereas stamping converts sheets into more complex shapes. Understanding the differences between these two is...
The use of plastics is extensive in today’s world, where most of them are manufactured with molding processes —the approach of shaping molten plastics by solidifying them in a cavity outlining the geometry of the desired item. Moreover, products made of plastic...
