01//About Us
Industrial Rebirth, Not Repair.
HuanXin Auto Tech specializes in remanufacturing core automotive components. We strictly follow original-equipment specifications with full-process quality control, using remanufacturing technology to lower the cost of vehicle ownership for car owners worldwide.
Remanufacturing is not repair. It is industrial rebirth: a worn part returns to factory spec, carries a written warranty, and ships with the same confidence as a new unit — while preserving the core value already locked in the material.
Green & Circular
Substantially less material, energy and CO₂ than new production — the circular economy in practice.
OE-Grade Rebuild
CNC machining, validated replacement parts and factory tolerances on every critical dimension.
Core Recovery
Used cores collected through a structured return network, graded by model and condition.
02//Product Lines
A Wide-Ranging Product Family.
From engines and powertrains to chassis, EV powertrain and in-vehicle electronics—every line is remanufactured to OE-grade specifications and backed by a written warranty.
Full-Vehicle Powertrain & Chassis Coverage
From EV battery and drive systems to the ICE engine and gearbox, we remanufacture the core parts of both powertrains under one quality system.
03//Why Us
Built on Process, Not Promises.
Five commitments that define how we work with every global partner.
OE-Grade Engineering Standards
Every unit is remanufactured strictly to original-equipment tolerances, using validated replacement components.
Full-Process Quality Control
From incoming core grading to 100% end-of-line performance testing, each unit is fully traceable batch by batch.
Warranty Commitment
All four product lines ship with a clear written warranty, giving your customers confidence on every fitment.
Green & Circular Manufacturing
Remanufacturing preserves the core value of used parts — substantially less material, energy and CO₂ than new production.
Stable Global Delivery
Stocked core SKUs with forecast-based replenishment and export-standard packing to keep your orders on schedule.

04//Remanufacturing Process
Eight Steps to Factory Spec.
Every unit passes through a disciplined, traceable process — from core recovery to after-sales support.
- 01
Core Recovery
Used cores are collected through our return network and sorted by model and condition.
- 02
Disassembly
Units are fully dismantled to component level for individual assessment.
- 03
Cleaning
Industrial washing removes oil, carbon and deposits without damaging machined surfaces.
- 04
Inspection & Grading
Each component is measured against OE limits; only reclaimable parts continue.
- 05
Remanufacturing
CNC machining, surface treatment and replacement of wear parts restore factory geometry.
- 06
Performance Testing
End-of-line benches verify boost, sealing, torque, light output and durability parameters.
- 07
Packaging & Warehousing
Anti-corrosion, shock-proof export packing with barcoded inventory ready for shipment.
- 08
After-Sales Support
Technical documentation, claim handling and a dedicated export support team.
VSR // BALANCINGDynamic balancing cells
High-speed dynamic balancing brings every rotor back to true rotation before final assembly, guarding reliability at highway speeds.
B&G // FLOW CALIBRATIONAir-flow calibration rigs
Each turbo is flow-calibrated against OEM curves to meet the exact commanded boost and efficiency windows.
EAS // TEST BENCHSteering performance test rigs
Rack units are load-tested for torque, assist force and return-to-centre behaviour against OE performance targets.
NVH // NOISE TESTNVH noise test benches
End-of-line acoustic testing keeps steering noise and vibration within OEM limits for quiet, refined operation.
RIGIDITY // SPRING TESTAir-spring stiffness test rigs
Spring-rate and damping curves are validated under controlled load to guarantee a factory-fresh, consistent ride height and comfort.
DAMPING // DYNO TESTAir-strut damping test benches
Full stroke / rebound cycling on servo-hydraulic benches verifies damping force, sealing integrity and noise under real road loads.
05//Closed-Loop // Reverse Logistics
Reverse-Logistics Solutions
We manage used cores for remanufacturing — efficient logistics plus structured core grading across the entire return flow, feeding each recoverable core into the right remanufacturing channel.
