    Frequently Asked Questions

    Answers to common questions regarding precision, tooling, materials, and our integrated molding capabilities.

    Most functional CNC and 3D printed prototypes are delivered within 3 to 5 business days. Our agile workflow and in-house machining centers allow us to prioritize urgent R&D cycles while maintaining strict dimensional accuracy for your engineering validation.

    We process a vast range of materials including aluminum, stainless steel, titanium, and copper, alongside engineering plastics like PEEK, PC/ABS, and Ultem. We ensure the prototype material mirrors your final production intent to provide accurate results during functional and thermal testing.

    Yes, our high-precision CNC centers and EDM equipment reliably hold tolerances as tight as ±0.01mm. This level of precision is essential for medical devices and robotics components where mechanical fitment and tight clearances are critical for assembly performance.

    Every project undergoes a rigorous Design for Manufacturing (DFM) review before production begins. We identify potential molding or stamping bottlenecks early, suggesting geometric optimizations that reduce raw material waste and ensure a seamless transition from prototype to high-volume manufacturing.

    Our bridge tooling utilize rapid aluminum or soft steel molds to produce hundreds or thousands of parts in production-grade materials. This allows you to fulfill initial market demand or clinical trials while permanent, multi-cavity high-volume tools are still being optimized.

    We provide complete turnkey solutions including anodizing, electrolytic plating, heat treatment, laser etching, and ultrasonic welding. This integration eliminates the need for multiple vendors, allowing you to receive fully finished, assembly-ready components from a single, accountable source.

    We support your product development with flexible MOQ requirements starting from just a single piece for CNC machining and 3D printing. For bridge production runs, we can efficiently scale from 100 units to over 5,000 units depending on your testing needs.

    We apply IATF 16949-level quality protocols to our prototyping runs, including 100% CCD automated inspection and comprehensive metrology reporting. This ensures that every delivered part meets the rigorous safety and performance benchmarks required by Tier 1 automotive and medical OEMs.
