Core Category: Tools for Vehicle Maintenance & Repair
These tools are primarily used for automobile repair, maintenance, inspection, and related operations. Core requirements include high strength, high torque capacity, durability, and adaptability to automotive repair working conditions. Many tools must feature impact resistance and fatigue resistance.
- Sockets (Phillips sockets, hex sockets, socket heads)
- Extension bars (extension rods, universal joints)
- Ratchet wrenches (ratchet wrenches, reversible ratchet wrenches)
- Jacks (hydraulic jacks, mechanical jacks)
- Tire wrenches (cross tire wrenches, socket tire wrenches)
- Spark plug sockets
- Wrenches (torque wrenches, open-end wrenches)
- Basic automotive diagnostic tools
- Oil filter wrenches
- Brake service tools
- Shock absorber removal and installation tools
Application Scenarios: Automotive repair shops, 4S stores, auto beauty shops, household vehicle maintenance, etc.
Working Environment: Complex conditions (oil, dust, impact) requiring tools to withstand high torque and impact, with extremely high demands on strength and durability.
The core demands for auto maintenance and repair tools are high strength, high torque capacity, impact resistance, wear resistance, and compatibility with automotive repair conditions.
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.
We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines). Our maximum processing outer diameter is 60, and the minimum control tolerance is 0.001. Equipment includes Japanese CNC Tsugami, CNC Citizen, multi-station cold extrusion forming machines, 500T press machines, casting equipment, and various process equipment.
Our company has 300 employees, including 20 technicians, 10 engineers, and 15 quality control personnel. We have over 300 pieces of equipment. We implement 8S management and have passed ISO9001 and TS16949 automotive certifications.
