Automotive Applications
We provide custom manufacturing solutions for a wide range of automotive applications, supporting prototype development, engineering validation, and low-volume production with CNC machining, sheet metal fabrication, and 3D printing.
Manufacturing Difficulties and Solutions
Automotive projects often require high dimensional consistency, lightweight structures, and reliable assembly across multiple prototype iterations. Below are examples of manufacturing challenges we have helped customers overcome.
Complex EV Motor Housings
An EV development team encountered repeated assembly issues with motor housings supplied by different vendors. Multiple bearing bores, mounting faces, and cooling interfaces had to align precisely, but small dimensional variations caused additional fitting work during assembly.
After reviewing the CAD model, we optimized the machining sequence and datum strategy. Multi-axis CNC machining and dedicated fixtures were used to improve positional accuracy between critical features throughout production.
- Improved assembly consistency
- Reduced manual fitting during assembly
- Stable dimensional accuracy across production batches
Lightweight Aluminum Structural Components
A customer developing a lightweight vehicle platform needed aluminum structural brackets with thin-wall pockets and weight-reduction features. Previous parts experienced slight deformation after machining, affecting final installation.
We adjusted the machining strategy, optimized cutting parameters, and controlled the machining sequence to minimize internal stress while maintaining structural rigidity.
- Reduced machining deformation
- Improved dimensional stability
- Consistent fit during vehicle assembly
Precision Suspension Assembly Components
During suspension prototype testing, several components from different suppliers showed inconsistent mounting hole locations, resulting in repeated alignment adjustments during installation and validation.
Critical locating features were machined using controlled reference datums and verified through CMM inspection to ensure every production batch maintained the required assembly accuracy.
- Improved assembly repeatability
- Reduced prototype adjustment time
- Better consistency between mating components
