Finding a good prototype supplier can be critical to the success of a project, whether it's for a new product or an improvement to an existing one. Here are some key elements to consider when looking for a good prototype supplier: Expertise: The supplier should have experience and knowledge in the

20 Types of Plastic Materials – Complete Guide of Properties and UsesGoodTech MFG Engineer-focused guide for material selection in manufacturing and injection molding. IntroductionMaterial selection is critical in engineering and manufacturing. Material selection is critical in engineering and manufacturing. This guide provides engineer-focused insights into mechanical, thermal, electrical, and chemical properties of 20 commonly used plastics, helping you choose the right material for your application.

Ribs and bosses are essential features in plastic part design. They add strength, support, and help with assembly — but if not designed correctly, they can lead to cosmetic defects, weak joints, and mold complications. Goodtech MFG help you balance structural strength and cosmetic quality. Our engineering team reviews your 3D models and provides DFM reports, rib/boss optimization, and mold flow simulation support.

At Goodtech MFG Group, we support engineers with Design for Manufacturability (DFM) feedback, including draft analysis. Our team helps you: • Detect undercut or zero-draft issues • Suggest ideal draft for your material and finish • Avoid rework and tooling changes

What Is the Best Wall Thickness for Injection Molded Plastic Parts? When designing plastic parts for injection molding, one of the most critical decisions a mechanical engineer must make is choosing the right wall thickness. Wall thickness affects part strength, manufacturability, cycle time, and cost — and poor choices often lead to defects like warping, sink marks, or short shots.
