Elevate Your Product Performance with Precision-Engineered Components
Do you design complex parts with tight tolerances and intricate features? If so, standard injection molding may not deliver the accuracy and consistency your project demands. Precision injection molding requires specialized expertise. It also demands advanced equipment and meticulous attention to detail at every step.
At Fathom, our precision injection molding capabilities enable us to produce precise plastic components with complex geometries, exceptional dimensional accuracy and superior surface finishes. Our team is very skilled at producing small, intricate parts that maintain consistent quality from one production run to another. This makes us a valued partner of customers in the medical, defense, aerospace and other industries where high performance is non-negotiable.
Our Advanced Precision
Injection Molding Capabilities
Precision Tooling Expertise
Successful high-precision injection molding starts with exceptional tooling. Our expert toolmakers use in-house, state-of-the-art machine tools to build mold tools with precise specifications:
Wire EDM Technology // Wire EDM cutting can create intricate features in hardened steel. It does this with a precision that’s not possible using CNC machining.
CNC Hard Milling // CNC machining is used to achieve complex, high-precision geometries while providing smooth surface finishes.
Multi-Axis Machining // This type of machining produces complex features that are impossible with single-axis machining.
Advanced Cooling Systems // Some parts need enhanced cooling in order to achieve acceptable cycle times and minimize part warpage. In these cases, Fathom’s Hartland, WI facility can 3D print metal cores with conformal cooling channels. These cooling channels are located just below the surface of the core and place cooling water as close as possible to the part for maximum cooling.
