Elevate Your Product Performance with Precision-Engineered Components
When designing complex parts with tight tolerances and intricate features, standard injection molding simply won’t deliver the accuracy and consistency your project demands. Precision injection molding requires specialized expertise, advanced equipment and meticulous attention to detail at every step.
At Fathom, our precision injection molding capabilities enable us to produce components with complex geometries, exceptional dimensional accuracy and superior surface finishes. Our engineering team excels in producing small, intricate parts that maintain consistent quality across production runs. This makes us a preferred partner for medical, defense, aerospace and other industries where high performance is non-negotiable.
Our Advanced Precision
Injection Molding Capabilities
Precision Tooling Expertise
The foundation of successful high-precision injection molding starts with exceptional tooling. Our expert toolmakers utilize in-house, state-of-the-art equipment to create molds with exacting specifications:
Wire EDM Technology // Wire EDM cutting creates incredibly precise cavities and features in hardened steel not possible via machining.
CNC Hard Milling // CNC machining is used to achieve complex, high-precision geometries while maintaining exceptional surface finishes.
Multi-Axis Machining // Produce complex features that would be impossible with single-axis machining.
Advanced Cooling Systems // 3D-printed metal cores with conformal cooling channels are an option to cool parts faster, reduce cycle times and minimize part warpage.
