Types of Custom Automotive Stampings
Yichen has experience in designing and manufacturing over 1000 types of automotive stampings.
Bending
Bending is a forming process that shapes metal sheets along a straight axis to create L-, U-, or V-shaped profiles. It is commonly used in parts such as control arms and chassis reinforcements.
Blanking
Blanking involves cutting a flat blank from a metal sheet to define the basic outline of a part. It is typically used for outer door panels, heat shields, and floor pedals.
Deep Drawing
Deep drawing forms hollow or cylindrical shapes by stretching sheet metal into a die. It is applied to product components like oil pans, shock absorber covers, and fuel tank liners.
Piercing
Piercing uses a punch to create holes or openings in metal blanks. It is used for engine brackets, steering plates, and sensor housings that require accurate hole positions.
Flanging
Flanging bends the edge of a metal part at a set angle to support strength. It is commonly applied in chassis bushings for structural stability.
Specialized Automotive Stamping R&D Team
Our R&D team has deep experience in forming high-strength steel and aluminum alloys for automotive applications. By using CAE simulation and DFM analysis, we identify and reduce early forming risks-such as cracking, wrinkling, thinning, or springback-ensuring smooth manufacturability. This allows components to meet OEM requirements for strength and fatigue performance in critical areas like suspension and body-in-white structures.
Comprehensive IATF 16949 Quality Management System
We are IATF 16949 certified and follow five core quality tools:
- APQP: Supports design reviews and process analysis to align with OEM requirements.
- PPAP: Provides documentation and sample validation for smoother project launches.
- FMEA / MSA / SPC: Enable risk assessment, measurement evaluation, and process control for consistent quality.
Rapid Prototyping
For sample testing or small-batch production, we accept orders starting from just one piece (MOQ 1). We can deliver sample parts in about 7 days. This allows customers to quickly confirm whether the size is accurate and the material meets basic requirements.
Industry-Leading Precision and Batch Consistency
We use high-precision blanking machines and real-time monitoring systems to keep part accuracy within ±0.0005 inch. By controlling mold temperature and using automated inspection, we ensure every batch has stable size and mechanical strength-meeting the strict requirements for assembly and load-bearing in chassis and body components.
CAE Analysis in Automotive Tooling Development
In developing automotive stamped parts, we use CAE (Computer-Aided Engineering) tools to simulate stamping dies under real production conditions, including temperature, force, and material behavior.
Yichen adjusts die shape and process settings before making physical samples, helping shorten debugging time by up to 30%.
We use CAE results to spot problems that might occur during stamping-such as cracks, material thinning, or shape distortion. Then we use these findings to prepare stamping instructions and production guidelines that help set up the tooling and adjust process parameters. This helps make sure that important parts like body panels and suspension brackets are stamped accurately and meet strength requirements.
Automotive Welded Assembly Manufacturing
In automotive body and chassis structures, many components require a combination of stamping, welding, and other processes for complete manufacturing-such as HVAC brackets, chassis mounts, control arm supports, and seat slide rails.
At Yichen, we provide a one-stop solution with a wide range of advanced welding technologies, including spot welding, TIG welding, laser welding, and friction welding. Each method is selected based on the material type and the performance requirements of the load-bearing area.
Our fully automated robotic welding units ensure precise control of welding parameters, delivering consistent weld quality with minimal heat distortion.
