The supplier faced a stark choice: scrap the existing tooling and source a new custom tooling supplier, or risk missing delivery commitments to their OEM customer. They chose the former—and began searching for a tooling manufacturer Dongguan could deliver a robust, high-precision die that would eliminate defects, extend tool life, and restore production throughput. They found SSPrecision.
The Solution: Engineered for Performance, Built for Scale
SSPrecision (SSP) —a Dongguan-based custom tooling supplier since 2008—approached the challenge with a comprehensive engineering review. Operating from a 9,000 m² ISO 9001:2015 and IATF 16949 certified facility, SSPrecision’s engineering team conducted a full Design for Manufacturability (DFM) analysis on the EV connector housing—evaluating part geometry, material behavior, and the supplier’s production volumes to recommend an optimized die configuration.
The SSPrecision Approach: Four Key Interventions as a tooling manufacturer
| Intervention | SSPrecision Implementation | Outcome |
| 1. Strip Layout Optimization | Redesigned from 61% to 78% material utilization | Reduced material waste and per-part cost |
| 2. Tool Steel Upgrade | D2 tool steel with vacuum hardening and PVD coating | Extended tool life from 500K to 2M+ cycles |
| 3. Precision Clearance Engineering | Optimized punch-to-die clearances for EV-grade copper alloy | Eliminated burr formation at critical edges |
| 4. In-Die Sensor Integration | Installed real-time SPC monitoring for dimensional drift | Detected deviations before defects occurred |
The design phase was critical. SSPrecision’s engineers ran advanced CAE simulation of metal flow and springback to optimize station sequencing, ensuring the part would not distort as it progressed through the die. The strip layout was refined from the supplier’s previous configuration—increasing material utilization from 61% to 78% and significantly reducing waste.
Tool steel selection was another high-impact decision. The previous die had used standard tool steel without adequate hardening. SSPrecision specified D2 tool steel, vacuum-hardened to 58–62 HRC, with PVD coating for wear resistance. The combination delivers documented tool life exceeding 2 million cycles.
Precision clearances were engineered for the specific material—an EV-grade copper alloy with tight conductivity requirements. SSPrecision’s machining capability of ±0.002 mm on die components ensured that punch-to-die clearances were held to micron-level accuracy, eliminating the burr formation that had plagued the previous tool. Every component was verified on in-house CMM (Coordinate Measuring Machine) with full measurement traceability.
Finally, SSPrecision integrated in-die sensors and SPC monitoring into the tool—enabling real-time detection of dimensional drift before parts went out of spec. This predictive approach prevents scrap rather than merely detecting it.
The Result: Measurable Impact on the Production Floor
The new SSPrecision progressive die was installed and validated within the supplier’s production line. The results were immediate and measurable:
| Metric | Before (Previous Die) | After (SSPrecision Die) | Improvement |
| Scrap Rate | 12% | <1% | 92% reduction |
| Tool Life | 500,000 cycles | 2,000,000+ cycles | 4x increase |
| Burr Formation | Present at critical edges | Eliminated | 100% elimination |
| Dimensional Drift | ±0.025 mm over run | ±0.005 mm consistent | 5x improvement |
| Unplanned Downtime | 3-5 days per repair | <1 day per year | 95% reduction |
| Material Utilization | 61% | 78% | 28% less waste |
The SSPrecision die now produces consistent, zero-defect parts across every production run. The supplier has achieved full IATF 16949 compliance for their EV battery program, with PPAP Level 3 documentation provided by SSPrecision. Scrap-related material costs have been virtually eliminated, and unplanned downtime has dropped to less than one day annually—restoring production throughput and ensuring on-time delivery to their OEM customer.
Beyond the immediate production metrics, the supplier gained a strategic advantage. SSPrecision’s IATF 16949:2016 certification—the automotive industry’s gold standard for quality management—provided the regulatory documentation required for their EV supply chain audits. The full material traceability and CMM dimensional reports satisfied their quality auditors. And with 99% on-time delivery maintained through disciplined production scheduling, they now have a reliable supply chain partner for future programs.
