Core components prefer Chrome Vanadium Steel (CR-V) and Chrome Molybdenum Steel (CR-MO). Alloy structural steel can be used for high-end products. Jack cylinders can be made of high-strength cast iron or aluminum alloy.

• CR-V: High toughness and impact resistance, suitable for torque-bearing tools such as sockets and wrenches
• CR-MO: High strength, high toughness and corrosion resistance, ideal for heavy-duty, high-temperature conditions (engine repair), the preferred material for high-end auto repair tools
• High-strength cast iron / aluminum alloy cylinders: Ensure load capacity and sealing performance of jacks, preventing bursting during use

• Torque & Impact Performance: Materials must be evaluated for tensile strength, yield strength and impact toughness to avoid breakage or deformation
• Wear Resistance & Fatigue Resistance: Contact surfaces require hardening treatments; moving parts need fatigue-resistant materials for extended service life
• Working Condition Adaptability: Anti-rust and anti-corrosion treatments; structural optimization for confined automotive spaces; safety features including anti-slip and anti-tipping designs

We produce individual parts for auto repair tools, including socket heads, extension bars, ratchet wrench bodies, jack cylinders, tire wrench heads, etc. We provide forging, machining, heat treatment, surface hardening and other processes to ensure torque capacity, impact resistance and wear resistance.

We complete full assembly of auto maintenance tools: socket & extension bar connection, ratchet mechanism assembly, hydraulic jack system assembly, etc. Assembly precision and safety performance are strictly controlled to meet heavy-duty automotive repair requirements.

We support OEM / private label production. Custom specifications available per customer requirements: socket sizes, torque ratings, vehicle model compatibility, etc. We provide one-stop service from parts processing to finished product delivery, and can manufacture supporting accessories.
