Wall Thickness, Complexity and material usage are examined as an integral part of our manufacturing process.
National Molding offers many types of engineering services to its customers:

How to use part coring to improve strength, lighten part, minimize distortion and improve surface finish. How to design parts with simpler "low cost" parting line locations. How to avoid Side Action "Cam" charges by using Under/Over cores.

National Molding offers many types of prototype services to its customers:
Rapid Steel Production tools in 2 to 6 weeks with Production Quality Parts. Rapid Sterolithography Prototypes in 2 to 5 days in Functional Materials. 3D Machining of actual Acetal & Nylon to produce small runs in 2 to 5 days. Rapid Soft Tooling to make functional injection molded parts in 5 to 10 days. Photorealistic Renderings of concepts for customer review. 

Our fully automated production process improves quality and reduces cost.
