Products and Services

Project Management
The staff at Marne Plastics is dedicated to managing projects from concept through production and service periods.  We have experience managing hundreds of projects through direct communication with OEM representatives.

Marne will build both prototype and production tooling for your part design.  The tooling will be matured and prepared for production at Marne. Prototype sampling can be completed even if the production business has not been awarded yet. Tooling can be manufactured by USA or Canadian tool builders or at low cost Asian tool makers as required.

Molding parts in the 100-550 Ton machine size is Marne’s core business.  We would like the opportunity to bid on any job whether it is low or high volume. Marne can mold many types of material, including grades that have glass or are difficult to process.

Post Molding Processing
Marne works with their customers to provide services that add value to the molded product such as assembly, decorating or welding.
