Custom Molder

As a manufacturer of high precision components and assemblies, FDA Class 1, 2, and 3 products, Minnesota Rubber and Plastics specializes in finding solutions to tough applications which require the molding and assembly of close tolerance components. We offer a wide range of technical services and production capabilities from Design for Manufacturability (DFM) to Lean Six Sigma best practices, producing close tolerance injection molded components, assemblies, and final sterile packaging.

Our range of processing capabilities extend from Thermoplastics to Rubber including, Liquid Silicone Rubber (LSR) and Gum Stock Silicones, or High Consistency Rubber (HCR).

Our specialty processes and services include:

  • High performance plastics such as PEEK, Torlon®, Aurum® PI and more
  • Custom Seals and Shapes
  • Insert Molding in Thermoplastics, Rubber and Silicone
  • Two shot molding
  • LSR Molding
  • Rotary Seal Rings and Thrust Washers
  • Rubber to TPE Conversions
  • Metal to Plastic Conversions
  • Bonding for plastic to metal, plastic to rubber and plastic to plastic
  • Over molding
  • Hotplate, rotational and ultrasonic welding
  • Adhesive bonding, hot stamping and machining
  • Product testing, assembly and packaging
  • Unified project management
Product Design Assistance or Support

We have dedicated and highly experienced Product Design Engineers that are ready to collaborate with you on providing Product Design Assistance to ensure successful and timely launch of differentiated solutions. Our product design engineers conceptualize and evaluate ideas by combining science and technology to create value. Their development role is facilitated by digital tools that allow them to visualize and analyze new designs, materials and products.

Our experience in computer aided design allows us to accept files from all CAD systems. Internally our primary CAD system is I-DEAS®. We also work with PRO/Engineer®, Solidworks®, Unigraphics® NX and AutoCAD®.

Our FEA software is especially well suited for conducting non-linear FEA on elastomeric or plastic components. FEA allows us to solve problems regarding component stress, strain, displacement, friction, thermal and impact issues as well as manufacturing simulations such as part removal from the mold.

Mold flow analysis optimizes the mold design process, the mold and the products design to improve quality and reduce cost as well as time-to-market. We utilize SIGMASOFT® Software by SIGMA Engineering GmbH of Aachen, Germany. This is a powerful molding analysis package which is capable of analyzing thermoplastic and thermoset molding.

Material Science

Over 1,000 active custom compound formulations with agency approvals.  Fully functional R&D facility for new material development, supplier/material evaluations and testing, including compounding and prototyping capabilities.


REDUCING FRICTION Quniton® serves as a highly lubricious material compound with performance capabilities uniquely designed to improve and withstand application needs. Formulated to have a low coefficient of friction, it resists bonding or sticking to a wide range of materials diversifying interface capability.

Engineering and Design Services for Medical Device Manufacturers

From proposal, through design to prototyping to final production, our state-of-the-art design engineering services provide timely answers to difficult design issues. Leveraging tools and expertise such Design for Manufacturability (DFM), Finite Element Analysis (FEA) and Mold-Flow analysis allow us to offer design alternatives quickly and precisely, while our tool development and secondary press operations are second to none. Finally, prior to committing to production, our prototyping services provide you with production quality sample parts for final testing.
