Thermoplastics and Thermosets

We injection mold parts using all sorts of material: Liquid silicone rubber (LSR), TPE, TPU, Polypropylene, Polycarbonate, ABS, PEEK, Nylon, etc.

We consider ourselves "high mix", meaning, we mold and assemble a wide range of products -- from complex medical and highly regulated device assemblies, to simple, single-station assemblies. Whatever you need, give us a call so we can help determine the best approach for you.

Our "in-house advantage" is just that. Our headquarters features an industry-leading tool shop, so your parts are molded using tools built here. If an adjustment is needed to a mold, we simply roll it down the hallway for machining and it's back in the press molding parts in no time. This is the ultimate setup for programs needing quick development.

Every project we undertake at MME group is approached with an engineering mindset. Our experienced team utilize all of our resources, processes and technologies to ensure that your project is completed successfully, on time and on budget.

But our capabilities extend far beyond engineering excellence. We also offer complete Supply Chain Management. We can source and manage all suppliers, and oversee the entire production schedule to get your product to market quickly and cost effectively. If you have an existing supply chain, we're happy to work with them as well. We are fully qualified to become your critical supplier and manage your ASL (Approved Supplier List). We will systematically and strategically coordinate all functions of your program with full responsibility and accountability.

Inventory Management is another service we provide. We apply lean manufacturing and KanBan control, storage and distribution services.

Engineering…Tooling…Molding…Assembly…Inventory Management…whatever service you require, and whatever industry you represent, MME group has the qualifications, certifications, experience and expertise to be your Contract Manufacturing partner.
