Company Profile

Products

Brake Discs Features:
• Ventilated brake discs remain the superior standard for front-wheel braking in modern vehicles
• Their unique double-layer hollow design integrates internal cooling fins, which efficiently dissipate the immense heat generated during braking
• This leading design delivers exceptional stability under continuous braking and superior resistance to heat fade, thus ensuring confidence during long-distance travel or frequent braking
• They achieve a perfect balance between high performance, long service life, and practicality for everyday driving
Tiered cast‑iron material solutions to match varied market positioning
Crafted from multiple cast‑iron grades ranging from standard grey iron to premium high‑carbon, G3000, GG15HC, DIN and SAE‑compliant formulas. Each material delivers differentiated performance in heat‑dissipation, noise suppression and thermal‑shock resistance. Whether for cost‑sensitive mass replacement or high‑demanding aftermarket retail projects, we have well‑aligned material options to fit passenger cars, SUV and light commercial fleets.
Globally‑recognized certification portfolio to unlock cross‑border business
Backed by IATF‑16949, ISO14001, ISO45001, ECE R90 and AMECA approvals. Independent lab testing validates structural robustness, thermal fatigue resistance and dimensional consistency. Complete certification paperwork removes barriers for customs clearance across Europe, North America and other key global territories.
Fine‑tuned turning‑grinding dual machining for smooth braking experience
Each rotor goes through precision lathe turning followed by fine surface grinding. We tightly control run‑out, parallelism and thickness deviation. This sophisticated processing effectively suppresses steering wheel shimmy, pedal pulsation and harsh brake noise, securing seamless compatibility with OE‑spec calipers and wheel hubs.
Modular anti‑corrosion toolkit for complex logistics & operating environments
We provide flexible anti‑rust workflows: rust‑proof oil dipping, paint finishing, protective coating and zinc‑dust treatment. These surface safeguards defend rotors from corrosion triggered by long‑time sea transit, damp warehouse storage and rainy‑climate road conditions. You can pick treatments based on your target market’s climate and shelf‑life requirements.
Customizable surface aesthetics for retail‑oriented sales
Four visual finishes are available: natural grey cast iron, sleek black paint, raw metallic texture and striking gold coating. It enables distributors to differentiate product lines, build‑up private‑label retail packages and cater to consumers pursuing both functionality and visual appeal.
Thermal‑optimized structure to combat heat‑related failure modes
Scientifically engineered ventilation vane layout accelerates heat evacuation during frequent stops and downhill descents. It curbs hot‑spot buildup, restrains thermal warping and crack occurrence. Well‑managed temperature also eases wear pressure on matched brake pads, extending the whole brake system service cycle.
1:1 OE‑reference dimension for hassle‑free swap‑out
Mounting face, bolt hole distribution and overall dimensions strictly follow original component drawings. No on‑car modification is required during replacement, guaranteeing precise fitment for designated vehicle platforms.
‑ Casting blank: Grey iron / High‑carbon cast iron (G3000, GG15HC, DIN, SAE grade). Optimized metallographic structure brings excellent vibration‑damping property, wear resistance and thermal conductivity, lowering squeal risk under daily driving.
‑ Surface anti‑corrosion: Oiled / painted / coated / zinc‑dust treatment optional
‑ Surface outlook: Grey, black, bare metal, gold
Smelting & composition calibration: Iron raw materials are molten, chemical components fine‑tuned to hit targeted grade standards.
Precision casting: Rotor blanks are formed, with strict process control to eliminate internal flaws like shrinkage cavities and porosity.
Stress‑relief annealing: Heat treatment releases residual casting stress to minimize post‑installation thermal deformation.
Blank screening: Visual inspection plus non‑destructive testing filters unqualified blanks before machining.
Turning: Rough and fine turning shapes mounting surfaces, outer profile and inner structures.
Double‑face grinding: Fine grinding ensures parallelism and uniform thickness.
Hole precision machining: Bolt holes and locating holes are processed in line with OE drawings.
Anti‑rust finishing: Apply customer‑specified anti‑corrosion treatments.
Multi‑dimensional quality audit: Run‑out testing, dimensional verification, appearance check; sample lab validation for certification compliance.
‑ Unit protection: Protective wrapping film against scratches and impact damage in transit.
‑ Branded retail box: Custom‑printed cartons supporting private‑label service, marked with OE numbers and vehicle application info.
‑ Outer shipment packing: Individual box, carton, pallet loading or bulk shipment. Heavy‑duty export‑grade packaging adapts to long‑haul ocean freight and mixed container loading.
Full set of certification documents simplifies customs procedures. Our rotors resolve frequent aftermarket pain points: brake judder, thermal warp, premature surface rust and bad fitting, helping importers cut after‑sales costs and complaint rates.
Plug‑and‑play OE interchangeability accelerates workshop fitting speed. Great compatibility with mainstream aftermarket brake pads simplifies daily repair operations.
Produced in Shandong, China. Multi‑grade material portfolio covers diverse price brackets. Custom branding is supported. Flexible packing allows mixed container loading together with brake pads and other brake parts to maximize container utilization.
Target global importers, wholesalers and independent repair chains for passenger cars & SUVs, covering European, North‑American and other international markets.
High‑quality casting and precise machining prevent irregular pad wear. Balanced service life helps car owners lower overall brake‑system maintenance expenditure.
