When it comes to injection molding for mission-critical parts, not all vendors are created equal. Choosing the right partner with the right resources can determine everything from production timelines to product performance.
Here are five key traits to look for in a high-performance molding partner:
1. Material Mastery
Can your molder work with ultra-high-performance resins like PEEK, Radel, Ultem, or Ryton? These materials require advanced processing and inspection equipment, including the ability to heat and maintain the Mold temperature at 400 degrees or more. Molding presses need to be of the appropriate tonnage, and the heating systems need to be upgraded to support the higher heat and electrical loads. And most important are the experienced technicians who understand heat profiles, gating, venting, ejection, shrink rates, and flow behavior.
2. Custom Tooling Capabilities
Look for in-house tooling services, including multi-axis CNC machining, EDMs, and the ability to build or modify tooling to meet your exact specs. At Action Plastic Injection Molding, our tooling department brings over 75 years of combined experience.
3. Certifications and Compliance
ISO 13485:2016 certification ensures quality systems meet the standards required in industries like Medical, Dental, Defense and Aerospace.
4. Full-Service Support
Does your partner offer value-added services like pad printing, sonic welding, subassembly, product packaging or drop shipping? The more support you get under one roof, the smoother your production flow.
5. Track Record and Responsiveness
A family-owned Corporation with over 30 years in operation, Action Plastic Injection Molding offers fast turnarounds, transparent communication, and precision you can trust.
