Automotive Assembly Torque Control
Automotive assembly lines demand the highest standards in fastening quality. Every safety-critical joint must be tightened with precision and documented with complete traceability — torque value, angle, timestamp and OK/NG result linked to the vehicle identification number. TMG provides the tools, controllers and integration services to meet these requirements across OEM, Tier 1 and Tier 2 plants in Mexico.
Industry Requirements
- VIN or barcode traceability: every tightening cycle linked to the vehicle or part identification for full audit trail
- OK/NG protocol per station: real-time pass/fail signal to PLC to halt the line on a non-conforming fastening
- PLC/MES integration: OPC-UA, EtherNet/IP and Profinet communication with Allen-Bradley and Siemens systems
- Reaction torque ergonomics: torque arms and balancers to eliminate operator fatigue and protect against musculoskeletal injuries
- Multiple assembly programs: configurable tightening strategies per joint type and station requirement
- Real-time data collection: cycle-by-cycle torque and angle data exported to MES or quality database
Recommended Products
For automotive assembly lines TMG supplies electric screwdrivers from Danikor and Sumake with transducerized torque and angle control, pulse tools from KEMP and Yokota for high-speed assembly, and torque controllers from NovaTork with VIN traceability and MES connectivity. Reaction arms and screw feeders complete the station setup.
Applicable Standards
ISO 9001 — quality management foundation. ISO 5393 — torque screwdriver performance and measurement standard. CQI-8 — AIAG guideline for torque and fastening control systems.
