Automotive part manufacturing starts with advanced HSLA steels of 350-800 MPa strength. Steel sheets with 0.6-2.5 mm thickness are formed in 1000-2500 ton presses. Die dimensional accuracy is maintained within ±0.1 mm. Resistance spot welding processes at 4000-8000 Amperes create joints. Each modern vehicle contains approximately 3000-5000 weld points. Cathodic anti-corrosion coatings of 15-25 microns are applied. These coatings guarantee salt resistance for up to 1000 hours. Chassis component heat treatment involves 880-920°C with rapid quenching. Quality control via CMM verifies ±0.02 mm accuracy.

Cylinder blocks are die-cast from A380 aluminum with 320 MPa strength. Cylinder walls are reinforced with Nikasil coatings of 120-150 microns thickness. Crankshafts are forged from 42CrMo4 steel with 800 MPa strength. Balancing precision is limited to under 1 gram per centimeter. Transmission parts are made from case-hardened 20MnCr5 steel with 58-62 HRC surface hardness. Gears feature surface finishes of Ra 0.4-0.8 micrometers. Exhaust systems utilize 409 stainless steel with 1.0-1.5 mm thickness. Catalysts use noble metals palladium and rhodium with 2-5 g/ft³ density. Engine component endurance testing runs for 1000 hours under maximum load conditions.You can order and buy car Bolts from Iran by contacting us through whatsaap and email.
