Manufacturing Process

Our manufacturing workflow is designed to provide consistent quality from engineering development through mass production.

Step 1 – Drawing & Requirement Review

Our engineers review the 2D/3D drawing, material specification, thickness, tolerance, slot configuration, hole positioning, and expected production quantity.

Step 2 – DFM Analysis

We evaluate the part structure and stamping feasibility, including material utilization, punching sequence, clearance, forming requirements, burr control, and tooling structure.

Step 3 – Stamping Die Design

A dedicated precision stamping die or progressive die is designed according to the rotor blade geometry and customer's production requirements.

Step 4 – Tooling Manufacturing

Tool components are manufactured using CNC machining, wire EDM, grinding, milling, and other precision machining processes.

Step 5 – Trial Stamping

Initial samples are produced for dimensional inspection and functional verification. If required, tooling adjustments are made before production approval.

Step 6 – Mass Production

After sample approval, production is transferred to controlled stamping operations for stable batch manufacturing.

Step 7 – Quality Inspection

Critical dimensions, hole positions, geometry, surface condition, burrs, and other customer-defined characteristics are inspected before shipment.

Why Choose METS?

Precision Tooling Makes the Difference

For silicon steel motor components, the quality of the stamping die directly affects the consistency of the finished laminations.

An improperly designed tool can lead to:

Inconsistent slot dimensions
Poor hole positioning
Excessive burrs
Material deformation
Low material utilization
Unstable production
Difficult stacking or assembly

METS approaches these challenges from the tooling side. Our engineers can optimize the stamping process, die structure, material layout, clearance, and production sequence before volume manufacturing.
