Precision Injection Molding
National Molding is a leader in tight toleranced and high performance plastic injection molding.
When working with National Molding, you will be working with a company who can fulfill all your plastic needs from initial design concept in 3D cad data to in-house tooling to full million part production runs.
With a focus on performance resins, we are able to optimize the injection molding process to achieve precision, strength and durability. Resins can be compounded to include fillers or additives which alter properties and performance. Characteristics can include lubricity, stiffness, electrostatic conductivity and flame retardants. All of our plants utilize raw material Moisture analysis
