At SIMKAB, we partner with manufacturers across energy, telecommunications, industrial machinery, and other demanding sectors. Below are selected projects that illustrate our engineering capabilities, quality standards, and delivery performance.
Solar Inverter Wire Harnesses
Challenge
A European solar equipment manufacturer relied on a Far East supplier for inverter wire harnesses. Lead times of 12 weeks, combined with inconsistent quality and rising logistics costs, were creating production bottlenecks and delaying product launches across EU markets.
Solution
SIMKAB’s engineering team designed custom wire harnesses purpose-built for solar inverter applications:
- High-temperature rated wires (125°C continuous) suitable for inverter enclosure environments
- UV-resistant braided sleeving for outdoor-rated junction box connections
- Weatherproof IP67 connectors with positive-lock retention
- Full electrical testing including continuity, insulation resistance, and hi-pot at 2.5 kV
Results
- Lead time reduced from 12 weeks to 3 weeks — eliminating production delays
- 100% first-pass yield at incoming inspection over 12 consecutive months
- Ongoing production of 2,000 units/month with Kanban-managed safety stock
- Total landed cost reduced by 18% compared to previous Far East supply chain
5G Base Station Cable Assemblies
Challenge
A telecom infrastructure company expanding its 5G network across the Middle East needed shielded cable assemblies that met strict electromagnetic interference (EMI) requirements. Existing suppliers could not meet the volume ramp while maintaining the shielding effectiveness specifications required for 5G frequency bands.
Solution
SIMKAB produced shielded multi-conductor cable assemblies engineered for base station environments:
- Double-shielded construction (braid + foil) achieving >90 dB shielding effectiveness
- Molex Micro-Fit and Mini-Fit connectors with strain relief and EMI backshells
- Full hi-pot testing at 1.5 kV DC on every assembly
- Traceability labeling with unique serial numbers and QR codes per assembly
- MIL-STD-compliant workmanship throughout the production process
Results
- 5,000 assemblies delivered in 6 weeks — meeting an aggressive network rollout schedule
- Zero field failures reported across all deployed units
- EMI compliance verified at independent third-party test lab on first submission
- Customer awarded SIMKAB a 3-year framework agreement for ongoing 5G expansion
CNC Machine Control Panel Wiring Harnesses
Challenge
A Turkish industrial equipment OEM was sourcing wiring harnesses for its CNC machine control panels from four different suppliers. Managing multiple vendors led to quality inconsistencies, version control issues, and excessive procurement overhead. They needed a single capable partner to consolidate all harness production.
Solution
SIMKAB took over the complete design and manufacturing of all control panel harness variants:
- Reverse-engineered and re-documented 15 harness variants with updated drawings
- Optimized wire routing and connector selection, eliminating redundant part numbers
- Introduced standardized color coding and labeling across all variants
- Implemented dedicated assembly boards with poka-yoke (error-proofing) fixtures
- 100% electrical testing with automated test equipment before shipment
Results
- 30% cost reduction achieved through design optimization and volume consolidation
- Single-source reliability — one point of contact, one quality standard, one delivery schedule
- Installation time at customer factory reduced by 25% due to improved harness routing
- Inventory carrying cost reduced through just-in-time delivery program
