Contract Manufacturing

Your one-stop shop company for all things contract manufacturing

After pilot production, full-scale manufacturing can begin, and the Mack group offers many capabilities for full-scale manufacturing. From small-scale production to high-volume production we can meet all your needs. A large variety of manufacturing resources are available for working with both plastic and metal parts. Plastic molding processes such as gas-assist injection molding and plastic injection molding allow flexibility in design. Metal parts can be cut to size using CNC machining as well as other sheet metal tooling. After manufacturing, inventory services are available to help give your product the final push to market. 

A century of injection molding experience

The Mack Group was among the first injection molders in this country to achieve ISO 9002 certification. Today, we hold certifications for ISO 9001, ISO 13485, ISO 14001, and IATF 16949. The Mack Group operates six injection molding facilities in the eastern United States, with 120 injection molding machines ranging from 28 to 4000 tons of clamp force, and shot sizes from .6 to 800 ounces. We are veterans at solid injection, structural foam, overmolding, gas-assist injection molding, and two-shot molding, and have processed the full gamut of performance materials from commodity grades to custom blends to conductive and engineering thermoplastic resins. Whether your product requires a single cavity, open and shut mold, or a complex, multi-cavity, multiple-gate, multiple-action tool, the Mack Group can handle your job.

It means everything stays in house for seamless transfer, accountability and transparency. We own the problem from start to finish leading to efficient team collaboration with reduced idle time between decisions. All with a goal of launching a well designed and manufactured product quickly the first time. 

An additional strength of the Mack Group's vertical integration of services is that you can pick and choose those that fulfill your particular manufacturing goals. You may want a full manufacturing partnership, where you can take advantage of all we have to offer or you may want to take a more a la carte approach. The possibilities are endless.
