Minnesota Rubber & Plastics specializes in overmolding solutions involving rubber, liquid silicone rubber (LSR), and plastic for critical applications. The company offers comprehensive services from formulation and design to prototyping, testing, manufacturing, and assembly. Their engineering team provides preliminary engineering assistance, mechanical design reviews, and material selection to ensure optimal performance and cost-efficiency in projects. The Advanced Materials Group collaborates with the design team to recommend suitable materials that meet demanding application conditions while ensuring repeatability in production. Their overmolding capabilities include LSR parts and various plastic materials such as nylon, polycarbonate, PPO, polysulfone, and polyphenylene sulfide. Minnesota Rubber & Plastics operates global manufacturing facilities in the United States, France, Mexico, and China, all adhering to strict ISO standards like ISO 13485, ISO 9000, and ISO-14001.
At Minnesota Rubber and Plastics, we specialize in rubber, liquid silicone rubber (LSR) and plastic overmolding for your most critical applications.
From formulation and design, prototyping and testing, through manufacturing and assembly, we have the overmolding solution to solve your most complex component challenge.
Design Solution
Through superior engineering expertise, our team will provide preliminary engineering assistance and mechanical design review, ultimately providing a recommendation of the best solution for your application. We’ll help you with decisions that drive performance and cost to ensure a successful project.
Our team can:
- Determine if your component requires overmolding or assembly
- Recommend when to chemically or mechanically bond.
- Can advise about the overmolded substrate, whether metal or plastic, taking into account the operating environment, production method, cost, and weight.
- Provide detailed guidance about the necessary mechanical design features that will promote a durable, high-performance bond.
- Model the solution with our best-in-class, non-linear finite element analysis (FEA).
Selecting the right material
Part of the mission of our Advance Materials Group, is to work hand-in-hand with our design team to recommend the right materials for bonding and overmolding. We work with a multitude of different chemical bonding agents and technologies to meet the toughest of application operating conditions, while ensuring a repeatable process in our production environment.
Liquid Silicone Rubber (LSR)
Turn to us to help you design and manufacture hard-to-build custom over-molded Liquid Silicone Rubber (LSR) parts. Learn more about our LSR capabilities.
Plastics
Overmolding onto plastic inserts can solve many design problems. The flexibility, toughness, solvent and chemical resistance of rubber is combined with rigidity, light weight, and cost savings of plastic.
Plastic materials commonly used in the bonding process include nylon, polycarbonate, modified PPO, polysulfone, and polyphyenylene sulfide.
