Injection molded plastics have revolutionized design, innovation, and manufacturing in the 20th century. Before 1950, most products were manufactured in stamped steel, die-cast aluminum, zinc, and ...

Injection-molded plastic part design is a lot like parenting. The job falls into your lap, you have zero qualifications, and yet, you are supposed to do it perfectly while blindfolded. It's difficult ...

In part one of this two-part article, design engineer Michael Paloian outlined the first four milestones of a product-design project, ending with the “cornerstone” of the product-design cycle — ...

Injection molding is a highly-engineered process that demands careful planning and attention to detail if the finished product is to achieve its full potential. The tips in this article should help ...

Editor's Note: An updated version of this information can be found here. What exactly is computer-numerical-controlled (CNC) machining? It’s a means to make parts by removing material via high-speed, ...

Designers of composite parts can choose from a huge variety of fiber reinforcements and resin systems. Knowledge of material properties is a prerequisite to satisfactory product design, but cost is a ...

An Injection molder looks at wall thickness differently than does the part designer. His concern, in addition to the strength of the part, is whether the mold will fill. All plastics families have ...

OpenSCAD has a lot of fans around these parts — if you’re unaware, it’s essentially a code-based way of designing 3D models. Instead of drawing them up in a CAD program, one writes a script that ...
