Challenges

Typical Difficulties and Solutions for Automotive Prototyping

Sheet Distortion in Thin Materials
We apply controlled laser cutting parameters and optimized clamping during forming to prevent warping in lightweight aluminum panels used in EV housings.
Springback in Precision Bending
Advanced CNC press brake compensation ensures accurate final angles for brackets and enclosures without repeated rework.
Weld Deformation Control
Strategic weld sequencing and heat distribution control minimize distortion in multi-part assemblies such as battery trays and support frames.
Complex Multi-Part Alignment
We use precision jigs and fixture systems to ensure consistent alignment across assemblies requiring tight multi-component fitment.
