We machine a wide range of materials including hardened tool steels (H13, D2, S7), stainless steels, aluminum alloys, copper alloys, and engineered plastics. Our multiaxis CNC and EDM processes handle materials up to 62 HRC with micron-level precision.
We routinely hold geometric tolerances of ±0.005 mm (5 microns) on complex features and can achieve ±0.002 mm on critical dimensions. Surface finishes down to 0.2 µm Ra (mirror finish) are standard for EDM and high-speed milling operations.
Lead times vary by complexity. Simple injection mold inserts may take 2–3 weeks, while multi-cavity progressive dies or complex molds with slides and lifters typically require 6–10 weeks. We provide detailed timelines during the quoting phase.
Yes, our engineering team collaborates with clients to optimize part design for manufacturability, gate and runner placement, cooling channel layout, and die clearance. We provide DFM feedback and 3D CAD models before production begins.
We serve automotive (interior/exterior trim, under-hood components), medical devices (diagnostic housings, surgical tool handles), consumer electronics (connectors, enclosures), and industrial packaging (caps, closures, thin-wall containers). All work meets ISO 9001 quality standards.
