Precision Problem-Solving
How To Engineer Complex Medical Tooling Solution Others Couldn't
The Client
A leading medical device manufacturer specializing in high-precision plastic components used in life-saving applications. Their products required strict regulatory compliance, biocompatibility, and flawless surface finishes to meet medical industry standards.
One of their critical components—a thermoset plastic mold—was causing serious production challenges due to its complex geometries and specialized coating requirements.
The Challenge
The client had spent years struggling to find a reliable supplier that could consistently manufacture this specialized mold with:
🔴 Intricate part and finish geometries – Standard machine shops and job shops couldn’t achieve the precision required.
🔴 A highly difficult release coating – The coating had to be applied with extreme accuracy to ensure clean part ejection without defects.
🔴 Lack of manufacturability guidance – Previous suppliers were unable to refine the design to improve quality, cost, and production repeatability.
🔴 Inconsistent supplier reliability – Due to the mold’s complexity, many vendors over-promised and under-delivered, leading to delays and high rejection rates.
Despite not being a traditional plastic mold manufacturer, Gromax saw an opportunity to apply its problem-solving expertise to develop a repeatable, high-quality production solution.
The Gromax Solution
Gromax took on the challenge that others had failed to solve by:
✅ Applying Advanced Problem-Solving Expertise – Even though we don’t specialize in plastic mold making, we leveraged our precision manufacturing experience to develop a scalable, repeatable solution.
✅ Refining the Process Over Six Months – Instead of a trial-and-error approach, we worked closely with the client to refine the design and process, ensuring it met manufacturability, cost, and quality targets.
✅ Optimizing the Print for Production – We collaborated with the client to redesign key features of the mold, improving its geometry for better manufacturability while maintaining strict functional and aesthetic requirements.
✅ Developing a Specialized Coating Application Method – The mold required a highly technical release coating, which we tested, refined, and perfected for consistent, defect-free part ejection.
✅ Delivering a Scalable, Production-Ready Tooling Solution – Once optimized, we delivered high-quality, production-ready molds, eliminating the client’s long-standing supplier issues.
By focusing on design refinement, process optimization, and precision execution, we transformed a seemingly unmanageable production issue into a scalable success story.
The Results
The optimized tooling solution delivered by Gromax provided immediate, measurable benefits:
📉 Eliminated supplier failures – The client no longer had to search for unreliable vendors, ensuring consistent quality and on-time production.
🎯 Achieved flawless mold geometry and finish – The redesigned tooling met all precision and finish requirements, allowing for smooth plastic part ejection.
💰 Reduced production costs – Process refinements led to lower manufacturing costs and improved efficiency.
🚀 Ensured long-term reliability – The new tooling was scalable and repeatable, eliminating the need for constant supplier troubleshooting.
📈 Accelerated go-to-market timeline – With a reliable mold in place, the client reduced delays and streamlined production, improving time-to-market for their medical device.
By solving what others couldn’t, Gromax not only delivered a high-functioning production mold but also provided the client with a scalable, long-term solution.
