  • A Stress-Free Partnership

    Cooperation Process

    1. Discuss Your Needs

      Engage with your account representative to discuss specifications and submit drawings, annual volumes, target pricing, performance needs, operating conditions, delivery timeline, regulations, and other critical details for a comprehensive understanding of your expectations.

    2. Engineering Collaboration

      Dedicated engineers review manufacturability using DFMA practices, perform tolerance stack analyses, optimize draft angles (target 2 degrees+) and wall thicknesses (as low as 2mm), develop prototypes via 3D printing, and otherwise ready parts for production over a 2 week timeline.

    3. Procurement Formalization

      Your account manager develops final quotation with target 10% savings off preliminary quote by value engineering. Payment terms at 30% deposit, 60% before shipment, final 10% after final inspection (within 30 days of order receipt).

    4. Specialized Production

      Leveraging approved CAD models, our experts execute production orders through casting (delivered in as few as 15 days from tooling completion), CNC machining (5 day avg lead time), cleaning (automated 16 station units), and intermediate quality assurance steps.

    5. Post-Processing & Surface Treatments

      Parts undergo any final finishing steps you specify - whether powder coating (avg 5 day lead time), plating (7 day avg lead time), passivation, chromating, or other processes guaranteeing satisfaction upon final inspections.

    6. On-Time Global Logistics

      Your dedicated logistics specialist manages secure packaging, customs/duties coordination, optimal carrier selection for your location, and on-time delivery coordination with tracking notification, getting your components delivered damage free when and where they need to be.
