GTP's Story

GTP was established in 1981 in a small facility located in Williamsburg, Michigan just outside of Traverse City. GTP has always been focused on delivering high-quality, cost-competitive components and assemblies that meet and exceed our customers’ requirements. The company began with a few presses along with a solid foundation of manufacturing, tool design and build and a focus on customer service. Over the next 35 years, GTP has grown to 22 injection mold machines, 3 plants located in 1 campus and over 100 dedicated employees.  GTP’s focus on quality and technology has provided the company opportunities to expand relationships with customers while providing our customers with components and assemblies for new applications and markets. GTP has also remained constant with technology and broadening our skill sets in material knowledge, automation, part design, error-proofing, manufacturability and tooling management.

Today, GTP is a USA owned Tier 1 and 2 supplier to the automotive, material handling, and industrial markets with a reputation in providing customers with components and assemblies using honed manufacturing capabilities, engineering expertise and experience in a wide-range of resin materials.  

While GTP continues to grow, the focus on customer service and quality remains.
