Design and Engineering

Metal to plastic conversions are becoming a very important development in the resin world, GTP works with suppliers for compounding of resins with specific characteristics that may be suitable for such applications. Our professionals at GTP have the expertise and knowledge to assure we can recommend the best possible resin for the task at hand.


Material Expertise

We understand plastic resins and our long-term relationships with our supply partners enhance this knowledge to generate meaningful material savings. We continuously work with customers to develop and implement alternate material solutions that meet performance requirements yet deliver meaningful year-over-year cost savings. In periods of cost inflation, GTP has mitigated nearly all impact to its customers through proactive procurement and Value Analysis/Value Engineering (VA/VE) solutions.

We rely on three main drivers that ultimately lead to cost savings:

  • Applications We understand applications and our expertise allows us to provide our customers with options that balance original material specifications and cost effectiveness
  • RequirementWe know and understand the pressures, performance standards and leading trends in component and assembly design in our core end-markets which gives us, and importantly our customers, the advantage they seek
  • ChemistryWe work with suppliers to create specific formulations and compounds that meet and/or exceed the expectations of our customers with an ever-present eye towards reducing cost
