Fine Blank Stamping Parts

Fine Blank Stamping Parts are precision-formed components critical to vehicle safety, performance, and assembly efficiency. Engineered from advanced high-strength steels (AHSS grades 340-1180 MPa), aluminum alloys (5xxx/6xxx series), and specialty coated materials (galvannealed/Zinc-Ni), these parts achieve dimensional accuracies within ±0.05mm for complex geometries. Key applications include structural reinforcements for crumple zones, fuel system brackets requiring 50MPa burst pressure resistance, and sensor mounts with vibration damping specifications (<0.8g RMS acceleration tolerance).

Our quality management protocols adhere to IATF 16949:2016 standards, incorporating three core validation stages:

Material Verification: Laser-induced breakdown spectroscopy (LIBS) ensures chemical composition compliance with SAE J403 for steel or AA standards for aluminum.

In-Process Control: Multi-axis CMMs with 5μm repeatability scan 120+ critical features per part, while AI-powered vision systems detect surface defects (e.g., micro-cracks <0.1mm).

Performance Testing: Component-specific validations include 250,000-cycle fatigue tests for door hinges (per GMN10053) and thermal cycling (-40°C to 120°C) for EV battery trays.

Drawing Design & Confirm

Get drawings from customers, or design drawings according to customers' detail requests or sample.
The two parties confirm the details of the drawings and product raw materials, surface treatment, etc.

Technical capabilities include:

Hot Stamping (PHS): Forming 1,500MPa ultra-high-strength parts for B-pillars and roof rails

Fine Blanking: Producing gear components with 0.005mm edge straightness

Hybrid Forming: Combining stamping with laser welding for integrated EV motor housings

Price & Order

Quote and confirm order quantity, specify all the details including trade terms, payment terms, type of package, etc.

Tooling Design & Manufacturing

Design and Make tooling according to the confirmed drawing, do the modification if needed while testing.

Production Process Design

Carry out technical assessment and analysis on product structure, design production process, and ensure the feasibility of the process.

Sustainability initiatives:

• 85% recycled content in cold-rolled steels (CR340LA/CR420LA)

• Water-based e-coating systems reducing VOC emissions by 60% vs solvent-based alternatives

• Closed-loop water recycling achieving 98% reuse in wash processes

Sample Approval

Make first samples and inspect them according to the drawing strictly.

Send to the customer for approval after internal approval.

  About our fine blank stamping parts: First of all, we use powder metallurgy steel molds, which can have a service life of up to 2 million times. In addition, compared to the traditional stamping process, our Fine Blank Stamping Parts are made in a single process, which greatly improves the work efficiency and product productivity.

Second, although our production efficiency has improved, the quality of our products has not decreased, because the precision stamping technology we use has good verticality and low surface roughness of the stamped section and can even be used directly without additional secondary processing.

Thirdly, our Fine Blank Stamping Parts can be molded in one go, regardless of whether it is a simple shape or a complex situation, and the spacing between our inner hole and outer edge breaks through the limitations of traditional stamping, which can be designed smaller to meet the needs of a wider range of customers.

Application: The automotive industry, which is also a core application area for our Fine Blank Stamping Parts. Specifically, it can be applied to the transmission system of the car, as the gear of the car movement, and can also be applied to the brake part, which is a part of the clutch. It can also be used in automotive safety systems, where our Fine Blank Stamping Parts can be made into ABS brake pads, airbag parts, and our Fine Blank Stamping Parts can also be made into metal buckles for seat belts, as well as ratchet mechanisms. In the engine, our Fine Blank Stamping Parts can be made into sprockets and tensioner guides to drive the engine around. Our Fine Blank Stamping Parts can be made into charging ports, motor cores and battery connecting pieces in new energy vehicles.
