Engineering before production

From material selection to a cost-effective process route.

We review function, material, geometry, tolerance, finish and order volume before recommending a manufacturing process.

Material Selection

Material is selected around the part's function, environment and target cost—not only the drawing name.

Strength, weight and corrosion exposure
Heat treatment and surface finish
45# steel, 40Cr, 5052/6061/7075, 304/316L and H59

DFM & Process Analysis

We review geometry before quotation to identify unnecessary cost and manufacturing risk.

Datums, wall thickness and tool access
Tolerance and Ra 0.4 μm requirements
Selected critical features up to ±0.001 mm after engineering review

Process Route Selection

Alternative routes are compared according to geometry, volume, tooling cost and repeatability.

Milling, turning or five-axis machining
Die casting or forging with CNC finishing
Laser cutting, bending or stamping

Cost Optimization

The recommended route is explained before production so the buyer can approve the technical and commercial trade-off.

Reduce setups and secondary operations
Avoid tolerances tighter than the function requires
Use stock size or near-net shape without compromising function
