Minnesota Rubber and plastics has extensive experience over molding a variety of rubber compounds – including Liquid Silicone Rubber (LSR) – over plastic, steel, brass and aluminum.
Large part or small – we have the over molding solution to solve your most complex component challenge. Rubber AND Plastics is truly one of our core differentiators, and we can do it all under one roof.
Let us know the over molding problem….We will design the solution
Utilizing our application engineering and design team will set you on the right path. Through their detailed interaction with you, they know when its best to over mold or just assemble, as well as when to chemically or mechanically bond. These are critical decisions which can drive product performance and cost for your project.
In addition, they know what to recommend for the over-molded substrate whether it be metal or thermoplastic, taking into account the operating environment, production method, cost, and weight.
And in those cases where we will over mold rubber onto thermoplastic, we do it all in-house, which is an advantage for you.
This team can also provide detailed guidance on the necessary mechanical design features that will promote a durable, high performance bond. They can help you make the right call on which over-molding method is best, and then model it with our best in class, non-linear finite element analysis (FEA).
Our advanced materials group recommends the right material for the job
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 over molding. 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) Over molding
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.
Have an over-molding project you’re working on?
Global manufacturing gives you more options
Your over-molded components can be manufactured and supported from any one of several locations we have around the world: United States, France, Mexico and China. Our worldwide manufacturing facilities operate under strict ISO guidelines including ISO 13485, ISO-TS 16949, and ISO 9000. These facilities operate under a corporate-wide Environmental Management System registered to the International Standards Organization series ISO-14001.
We wrote this for design engineers because you don’t have time to become an over-molded rubber and plastics expert. That’s our job.
To gain a better understanding of the processes, materials and technical considerations involved in the design and manufacture of over-molded rubber or thermoplastic components, read through our Engineer Design Guide. This comprehensive design tool details both rubber and plastic design issues including a materials overview and prototype mold design considerations.
