Simkab provides end-to-end wire harness and cable assembly services from our production facility in Istanbul. We support clients at every stage—from initial concept and design through prototyping, testing, and full-scale serial production. Our capabilities are built around flexibility, precision, and adherence to international quality standards including IPC/WHMA-A-620 and ISO certification.
Custom Wire Harness Design & Manufacturing
Every application has unique electrical, mechanical, and environmental requirements. Simkab specializes in designing and manufacturing custom wire harnesses tailored to your exact specifications. Our engineering team works from your schematics, 3D models, or even rough concepts to develop harness layouts optimized for performance, durability, and manufacturability. We select the right wire gauges, connectors, terminals, and protective materials for each project, whether it involves a simple point-to-point connection or a complex multi-branch harness with hundreds of circuits. All custom harnesses are produced in compliance with IPC/WHMA-A-620 workmanship standards.
Cable Assembly Production
Beyond wire harnesses, Simkab produces a wide range of cable assemblies for power distribution, signal transmission, data communication, and control systems. Our cable assembly capabilities include overmolding, shielded cable processing, coaxial assemblies, and multi-conductor configurations. We work with leading connector brands such as TE Connectivity, Molex, JST, and Phoenix Contact to ensure compatibility with your systems. Whether you need rugged assemblies for industrial machinery or precision assemblies for telecommunications equipment, our production lines are configured to deliver.
Engineering & Design Support
Simkab offers dedicated engineering and design support to help clients refine their wiring concepts before production begins. Our engineers can review your existing designs for manufacturability, suggest alternative components to reduce cost or improve reliability, and create detailed technical drawings and bills of materials. This collaborative approach reduces development time and minimizes costly revisions during production. If you are unsure where to start, our team can guide you through the entire wire harness design process from requirements gathering to final documentation.
Prototyping & Sample Production
Before committing to a full production run, it is critical to validate your design with physical prototypes. Simkab offers rapid prototyping and sample production services that allow you to test fit, form, and function in real-world conditions. Our prototyping turnaround times are among the fastest in the region, enabling you to iterate quickly and move to production with confidence. Each prototype undergoes the same rigorous inspection and testing as our serial production units, so you can trust that the sample you approve is representative of the final product.
Serial Production & Fulfillment
When your design is finalized, Simkab scales up to serial production with consistent quality and reliable delivery schedules. Our production planning system ensures that materials are procured in advance, workstations are prepared with the correct tooling, and output meets your volume and timeline requirements. We offer flexible batch sizes—from small series for niche applications to high-volume runs for mass-market products. Simkab also supports custom packaging, labeling, and logistics coordination to streamline your supply chain. We serve clients in the energy sector, agriculture, telecommunications, and industrial machinery.
Quality Testing & Inspection
Quality is built into every step of our production process, but it is verified through comprehensive testing and inspection at the end of the line. Simkab’s quality lab performs a full range of tests including electrical continuity checks, insulation resistance testing, hi-pot (high-potential) testing, crimp cross-section analysis, and pull-force testing. Every harness is visually inspected against IPC/WHMA-A-620 criteria before it is approved for shipment. Our traceability system links every test result to the specific harness serial number, giving you complete visibility into the quality history of every unit you receive.
