Company Background

M.R. Mold & Engineering Tech center

In 1985, Rick Finnie started M.R. Mold & Engineering with only one employee. Today M.R. Mold is known around the world for its expertise in manufacturing molds for liquid silicone, gum stock silicones, as well as thermoplastic injection molds.  Over 30 highly skilled craftsmen, using cutting-edge technologies, make it possible for us to consistently meet or exceed our customers' expectations.

Rick's management team of Brian Geisel, Don Marple, and Mike Coleman have a combined 150 years of experience in the industry. On an average, M.R. Mold & Engineering's highly skilled staff have been with the company for 18 years. The longevity of our employees speaks volumes.

In 2005, M.R. Mold & Engineering introduced its 4,000-square-foot Technology Center with four company-owned molding machines. With this added capability, we offer:

  • Process silicone and thermoplastics (helping our customers realize their end product faster).

  • Sample all injection molds before they are shipped to our customers (sending samples ahead of mold delivery saves our customers precious time and money).

  • Offer our customers the ability to execute turn-key projects.

Additional square footage and molding machines have grown our capability over the years. Today, M.R. Mold & Engineering owns six state-of-the-art molding machines with both silicone and thermoplastic capabilities.

Our customers have made our success possible, which is why customer needs have always been—and will remain—our primary focus. Driven by our "Customer First” philosophy, we manufacture tools of exceptional quality that are competitively priced, defect free and delivered on time. From simple O-rings to complex parts with 3-D parting lines, no matter what the project, our goal is to be the premier liquid silicone source of the industry!
