I write about manufacturing projects that combine rubber, plastic, and metal. My articles look at when rubber and plastic molding may need to work together and what to ask about certification and traceability for rubber-to-steel bonded parts, helping readers define project requirements more clearly.
Rubber and Plastic Molding: When You Need Both Under One Roof
ENGINEERING BUYER GUIDE The search for rubber and plastic molding shouldn’t be defined as if they were the same job done two ways. They aren’t. Rubber and plastic molding is a sourcing program that can combine two distinct process families.…

Short answer: rubber to steel bonding certification isn’t one universal badge. Rubber to steel bonding certification is an independent, scope-limited conformity statement; it does not by itself approve every part or lot. A defensible approval package connects the named standard,…
Rubber Compound Selection Guide: EPDM vs Silicone vs Nitrile vs FKM
Rubber Compound Selection Guide: EPDM vs Silicone vs Nitrile vs FKM Engineering selection guide · Engelhardt Selecting a rubber compound is not a vote for the “strongest” polymer. A rubber compound selection guide is a structured way to compare formulation,…
Medical Injection Molding: Materials, Compliance & Manufacturing Requirements
Medical injection molding requirements are the material, quality, validation, traceability, and documentation conditions needed for a molded plastic part’s intended medical use. In practice, the question is not “Which resin is medical grade?” It is “What evidence must this molded…
Two-Shot Molding: Process, Applications & When to Use It
Two shot molding is a plastic injection molding process to make one component with two materials, two colors or two functional surfaces, in a coordinated series of molding steps. It’s relevant if the design is well established, the annual volume…
Structural Foam Injection Molding: Process, Benefits & Applications
Injection Molding Guide Structural foam injection molding is a foam-assisted thermoplastic molding process for large or thick plastic parts. For buyers, it is not just standard injection molding with bubbles added. It is a process family where resin, a blowing…
