Our custom sheet metal fabrication services produce components for passenger vehicles, commercial trucks, and electric vehicle platforms. We utilize progressive stamping, deep drawing, and precision bending processes for automotive applications. Production lines handle material thicknesses from 0.6mm for body panels to 8mm for chassis components, with coil-fed processing for high-volume runs. Welding operations include MIG, TIG, and resistance spot welding per automotive industry standards. We maintain process capability indices (Cpk) of 1.33 or higher for critical characteristics.
Our 5,000-square-meter facility includes 6 progressive stamping presses ranging from 160T to 630T, 5 CNC press brakes with automatic tool changers, and 3 robotic welding cells dedicated to automotive production. Monthly capacity reaches 250,000 automotive-grade stampings and fabrications. We support production part approval process (PPAP) submissions at Levels 1-5 per AIAG requirements. Standard lead times are 7-10 workdays for PPAP samples and 10-20 workdays for serial production after part approval.

Our facility operates under ISO 9001:2015 certification with processes aligned to IATF 16949 requirements for automotive production. We implement advanced product quality planning (APQP) for new automotive programs, with control plans developed for each part number. Statistical process control (SPC) charts are maintained for critical characteristics during production runs. Change points are documented and communicated to customers per automotive customer-specific requirements.
All steel and aluminum coils receive incoming material certification verification, including mechanical properties and chemical composition analysis. First-piece approval is required at every shift change, material change, and die setup. In-process audits occur every hour for critical dimensions. Finished parts undergo visual inspection per MASTER samples approved by customers during PPAP. All gages and measurement equipment are calibrated per ISO 10012 schedules with traceability to national standards.
We produce stamped brackets, reinforcement panels, and mounting plates for body-in-white assemblies. Exterior components include license plate brackets, mirror mounting bases, and trim retainers. All exterior parts are produced with Class B surface requirements, free from scratches, dents, and forming defects visible after final vehicle assembly. Edge conditions are controlled per customer specifications to prevent corrosion initiation points.
Our fabrication processes produce suspension mounting brackets, cross-member components, and heat shields for powertrain applications. Chassis components are formed from high-strength steel with controlled weld penetration and heat-affected zones. Exhaust system hangers and heat shields use stainless steel and aluminum-coated materials for high-temperature service. All safety-related components receive 100% visual and dimensional inspection before shipment.
For electric vehicle platforms, we produce battery tray brackets, busbar supports, and electrical enclosures. Components for high-voltage systems meet specified creepage and clearance requirements. EMI shielding components use specified materials and forming processes to maintain shielding effectiveness. We support specialized packaging for sensitive electrical components to prevent damage during transit.
Our engineering team supports new program development from design review through PPAP submission. We provide stamping simulation and formability analysis for complex deep-drawn parts to reduce tooling development time. DFM feedback is provided within 48 hours of drawing receipt, including material utilization rates and process risk assessment. We maintain dedicated program managers for automotive accounts to coordinate timing and quality requirements.
We support kanban and consignment inventory programs for production customers. Packaging is developed per customer specifications, with returnable dunnage options for high-volume programs. Lot traceability is maintained throughout production, with date coding and batch identification on all packaging. We provide capacity reservation for scheduled production programs to support customer build schedules. Non-conforming material is contained within 24 hours of notification, with sorting and replacement support as required.
We support PPAP submissions at Levels 1 through 5 per AIAG guidelines. Standard PPAP packages include process flow diagrams, PFMEA, control plans, measurement system analysis results, initial process studies, dimensional results, material certifications, and part submission warrants. Lead time for PPAP sample production is 7-10 workdays after tooling approval.
We maintain Cpk values of 1.33 or higher for customer-designated special characteristics. SPC data is collected during production runs and is available for customer review upon request. For dimensions with Cpk below 1.33, we implement 100% inspection until process improvements achieve the required capability.
All production parts ship with material certificates from the original mill, including chemical composition and mechanical property data. Heat number traceability is maintained from incoming coil through finished part production. Additional certifications including RoHS, REACH, and IMDS data submission are available upon request at the time of quotation.
Engineering changes are processed per customer-specific requirements. We maintain documented change control procedures that include tooling modification, first-piece approval, and old part disposition. Timing for implementation is communicated and agreed upon with customers before production changes occur. All previous revision parts are segregated and identified to prevent shipment after the effective change date.
