Top Rubber Molding Companies and Suppliers in the USA

Rubber molding is dominated both in the US and internationally by some very large, vertically-oriented producers. In the automotive sector, for example, companies such as Tenneco produce vast quantities of rubber parts for automotive OEMs which are used as individual components and as parts in manufactured assemblies. Such suppliers are not likely to be in a position to accept orders for custom-molded rubber parts due to the sheer volume of business they receive from their regular customers. Still, molded rubber parts are critical in many commercial products ranging from appliances to medical devices.

With that in mind, this article steps back a bit from listing the gargantuan companies for whom rubber molding is but a part of their larger operations and instead looks at US companies that do rubber molding as their main, or major, endeavor. For anyone looking to source rubber-molded products in the US, it is highly likely that any of the companies listed here would be happy to receive a call.
