Services
CNC Precision Machining
Our CNC machining services deliver complex components with tolerances down to 0.00005 accuracy. Using advanced equipment like our DMG MORI NHX 4000 RPP, we handle 4-axis machining, 3D surfacing, and complex geometries for aerospace and semiconductor applications. Our capabilities include horizontal/vertical sawing, live milling, and bar feeding systems for both prototyping and high-volume production.
O-Rings
We distribute precision-engineered o-rings in materials like Viton, silicone, and nitrile. With 50+ years of application expertise, we provide chemical-resistant, high-temperature, and FDA-approved sealing solutions for aerospace, medical, and industrial applications. Our inventory includes standard and custom sizes with specialized compounds like Kalrez and Teflon encapsulated options.
Gaskets
Our gasket manufacturing covers all compounds and configurations, including FDA-approved materials for food processing and medical-grade silicone. We produce complex shapes with tight tolerances using advanced cutting technologies, offering solutions for extreme temperatures, chemical exposure, and sanitary environments across semiconductor, aerospace, and pharmaceutical industries.
Industrial Components
We manufacture custom-engineered components for critical applications, including metal-to-plastic conversions and specialized fasteners. Our production integrates anodizing, plating, and passivation services with full traceability documentation. These components serve mission-critical roles in aerospace systems, semiconductor manufacturing equipment, and medical devices requiring strict compliance standards.
Aerospace Components
Our aerospace manufacturing meets stringent industry standards with materials like 7075 aluminum and 17-4 stainless steel. We produce flight-critical components with heat-resistant properties and complete documentation packages including first article inspections and certificate of conformance, supporting both commercial and defense aviation applications.
