injection molding vs blow molding

You are creating a product that will require molded plastic parts. While injection molding and blow molding are two of the most popular methods to create high-quality, affordable plastic parts and products that are cost-effective, they are not the same.…

How Injection Molding Supply Chains Work

No matter what industry or project in question, managing projects can be challenging. For injection molding management discipline and supervision are crucial. The Project Management Offices (PMOs) are now an accepted norm in the molding industry. They guarantee the highest…

Mold Design

For beginners, the only requirement is a little knowledge of mechanical drawing delineation, done either electronically via a computer (with programs like Autocad) or manually with a pencil on a drawing board. In addition to basic calculus, the designer must…

DFM and FMEA Reducing Molding Risk Probability
