Frequently Asked Questions
Q1: What minimum order quantities do you require for copper pressed parts?
Minimum order quantities depend on tooling requirements and production setup. For new parts requiring new die fabrication, typical minimum 5,000-10,000 pieces to justify tooling investment, with lower quantities possible for prototype tooling. For existing tooling, minimum quantities typically 1,000-2,000 pieces depending on setup time and material utilization. High-volume production runs offer best unit pricing through amortization of setup costs and material optimization.
Q2: How do you handle springback in copper forming operations?
Springback compensation incorporated in die design through overbending to achieve final angle after elastic recovery, selection of appropriate punch and die radii for material thickness, proper material grain direction relative to bend axis, controlled forming speed and dwell time, and post-forming operations including coining or restrike if required for critical angles. Beryllium copper and phosphor bronze exhibit more springback than pure copper requiring greater compensation.
Q3: What is the typical lead time for copper pressed parts with new tooling?
Standard lead time is four to six weeks for new tooling development and initial production, accounting for engineering analysis and strip layout design, die design and CAD modeling, die fabrication using CNC machining and EDM, die tryout and refinement, first article inspection and approval, and initial production run. Repeat orders using existing tooling have shorter lead times of 2-3 weeks depending on order quantity and scheduling.
Q4: Can you provide plating or surface treatments for copper pressed parts?
Yes, we provide comprehensive surface treatment services including tin plating for solderability and corrosion protection with thickness 2-10 microns per ASTM B545, nickel plating for wear resistance and corrosion protection, silver plating for premium electrical contact applications, gold plating for high-reliability connections in aerospace and military applications, selective plating for specific contact areas, and chemical treatments including passivation or conversion coating. All plating processes controlled and tested per applicable standards.
