Essential Core Features

Ventilated inner‑vane structure, effective heat dissipation for front‑axle working condition

Built‑in ventilation vanes accelerate hot‑air circulation during braking. It lowers operating temperature under frequent braking, effectively reduces heat accumulation. Widely used for front axle of passenger cars and SUVs, ideal for large‑volume standard aftermarket replacement business.

Balanced overall performance for daily commuting scenarios

Designed for ordinary urban driving. It delivers stable friction output and consistent braking feel under conventional stop‑and‑go conditions, meeting daily safety requirements without over‑engineered redundant performance.

Tiered cast‑iron grades for flexible market positioning

Multiple iron grades optional. Standard formula fits cost‑sensitive mass‑market repair‑shop orders; high‑carbon grade provides enhanced thermal fatigue resistance for customers pursuing longer service life. You can select grade according to local market demand without extra unnecessary cost.

Fully certified goods to simplify import compliance work

Comply with IATF‑16949, ISO management system, ECE R90 and AMECA standards. Complete test documents are well organized. When exporting to EU, North America and other regions, our certification resources can be directly adopted to save your compliance‑related time and labor cost.

Strict flatness and run‑out control to decrease garage installation rejection

Produced by turning and double‑sided grinding. Tight tolerance is guaranteed out‑of‑box. Repair shops can carry out direct installation without secondary processing, reducing on‑site failure rate and maintaining your good reputation among local garage clients.

Diversified anti‑rust solutions adapting to ventilated disc complex inner structure

Inner vanes bring hidden surfaces prone to moisture corrosion. We supply multiple anti‑rust options including oil‑dipping, painting, coating and zinc‑dust treatment. Prevent rust inside ventilation chambers during long‑distance sea shipping and humid warehouse long‑term storage.

Multiple surface finish options support multi‑channel sales layout

Original metallic finish for cost‑oriented bulk wholesale; black, gold and other coated appearances for high‑margin private‑label retail. Same item covers both large‑volume wholesale and premium retail business.

1:1 OE dimension replication for convenient inventory management

Mounting face, bolt holes, thickness and overall dimension strictly follow original samples. Direct bolt‑on replacement with no modification required, convenient for your OE‑number‑based stock management.

1. Manufacturing & Process Control

Ventilated cast blanks go through stress‑relief annealing to eliminate casting‑caused internal residual stress, lowering hidden thermal‑deformation risk under continuous braking. Each batch of raw blanks conducts non‑destructive testing before machining to screen internal defects such as blowholes and shrinkage cavities. Turning and double‑sided grinding adopt high‑precision fixture positioning. Critical indicators including run‑out, parallelism and thickness variation are strictly controlled. Complete production records are archived for full‑batch traceability.

2. QC & Factory Inspection

All finished brake discs complete 100% run‑out inspection. Hardness, dimension and surface condition are sampled according to standardized inspection specification. Periodic laboratory tests cover thermal fatigue test and burst strength test to verify safety performance under real‑world working temperature. Non‑conforming products are independently isolated to avoid mixing into finished goods. Inspection and lab test reports can be provided upon request.

3. Supply Chain & Delivery Performance

Standardized process ensures stable batch consistency; dimension and hardness keep small fluctuation even under large‑volume orders. Hot‑selling part numbers keep blank stock to support short lead‑time. For custom new items developed from customer samples or drawings, clear sampling and mass‑production schedule will be offered. Flexible MOQ applies for stock goods and private‑label orders. Sample service is available; sample fee will be refunded after formal bulk order confirmation. Sufficient monthly production capacity handles peak‑season urgent orders.

4. Packing, Storage & Shipment Protection

Various anti‑rust technologies guarantee reliable performance for long‑haul sea transportation and long‑term storage in high‑humidity warehouses. Each brake disc is wrapped by protective film to avoid surface scratch and edge chipping in transit. Pallet loading uses inner support and filling materials to mitigate squeezing damage inside containers. Custom label service supports printing customers’ own part numbers and fitment information on inner boxes and outer cartons. Mix‑loading with brake pads and other brake spare parts is supported to help buyers reduce freight cost.

5. Compliance, Certification & Document Service

Full‑set certification and test documents are sorted for customs clearance usage. We can issue packing list, commercial invoice, certificate of origin and other trade‑required documents. OE cross‑reference tables and vehicle fitment data can be supplied to assist buyers to organize product catalog and manage inventory system.

6. After‑sales & Commercial Supporting Service

Provide one‑stop private‑label solution, including packaging suggestion, artwork confirmation and printing production. Technical supporting materials such as installation reminders can be offered for buyers’ local repair‑shop partners. New‑product development is acceptable based on customer samples or drawings. Standard evaluation process is available for batch‑quality‑related claims.
