Through the years, World Class Plastics has been a growth- and innovation-driven service provider, with a range of successful projects that include custom plastic injection molding solutions. We have experience working with clients across various industries, including automotive customers, industrial manufacturers, and others, using robust and repeatable processes to enhance part quality and maintain repeatable output.
In this case study, learn how we used our plastic injection molding experience and advanced equipment to provide consistently high-quality components for a market-leading industrial manufacturer: Worthington Enterprises.
The Challenge
World Class Plastics partnered with Worthington Industries to address significant production challenges for a critical valve component for their tanks division. Worthington’s tanks division had been experiencing issues with part quality and frequent failures from previous suppliers, which jeopardized their valve assembly process. The stakes were high, as each cylinder could contain up to $400 worth of product.
Worthington needed a reliable partner to manufacture plastic valve components that could meet stringent quality and performance standards. Key challenges included ensuring the parts were flash-free, held tight tolerances, and remained concentric after being molded to promote reliable fit and function. The parts also needed to be able to withstand extreme torque across a range of temperatures.
The WCP Solution
World Class Plastics was chosen by Worthington due to a combination of factors, including our local presence, direct delivery capabilities, and our reputation for providing high-quality products at a reasonable price. Our team’s engineering and technical support were crucial in developing a solution to address Worthington’s challenges.
We leveraged our extensive expertise to help Worthington design a new mold capable of producing millions of shots without defects. A key part of our process involved implementing Cavity Pressure Technology to monitor and trigger the injection molding process, ensuring consistent, high-quality across parts, even with changes in material lot numbers and typical material fluctuations. We also implemented in-process testing and inspections, including destructive testing, visual inspection, and dimensional documentation, to ensure every component we delivered met the required specifications.
Results and Impact
The partnership with World Class Plastics enabled Worthington to overcome its quality control and part failure issues. We began manufacturing over 1,000,000 units per month as an ongoing supplier, delivering parts on a consistent schedule directly to their location in Worthington, Ohio. Our commitment to quality and service was recognized with multiple awards from Worthington over the years, including the Technical Achievement award and our designation as a Certified Supplier.
Over the last 22 years, we have been Worthington’s primary supplier of custom plastic injection molding, a testament to the trust and positive feedback we’ve built with their team. Their team continues to rely on our engineering capabilities, our high-volume production capacity, and our commitment to lean manufacturing, all of which are backed by our ISO 9001:2015 certification.
