Precision Metal Stamping

MADE IN TAOYUAN, TAIWAN

Taiwan metal stamping, from die development to finished part on one production line

Sonnarkraft is a Taiwan metal stamping manufacturer that runs stamping, surface finishing and assembly inside a single plant in Luzhu, Taoyuan. Parts do not travel between subcontractors, so tolerances, finish quality and lead time stay under one roof and under one quality system.

Press capacity and part envelope

Our press line covers everything from simple flat blanks to curved and multi-angle geometries, with in-house tooling development for each programme.

PRESS TONNAGE
60 – 200 ton
MAX STAMPING SIZE
L 170 cm × W 70 cm
SHEET THICKNESS
up to 2.0 mm
FORMING
flat, curved and multi-angle geometry

Tooling and engineering support

We develop and maintain tooling in-house and work from your 2D or 3D data. During development we review formability, radii and burr control before the first die is cut, which keeps rework and sampling loops down.

In-house die design, build and maintenance
Review of formability, corner radii and springback from 2D / 3D data
Prototyping and pilot runs before volume release
Expanded-metal and mesh forming capability

Quality management

Every programme runs under an automotive-grade quality system, with measurement equipment on site rather than outsourced.

Traceability

Production is scheduled and recorded in ERP. Every batch carries a lot number with its inspection data, so any part can be traced back from delivery to incoming material — which is what makes customer audits straightforward.

PROCESS

From tooling to volume production in four stages

Documents issued at each stage are adjusted to the part and the customer's requirements.

01
Drawing and feasibility review
2D or 3D data is reviewed by engineering for manufacturability before a quotation is issued.
02
Tooling
Dies are built in our own tool room. Die modification and stamping take place in the same plant.
03
Trial run
Trial parts are measured on the CMM against the drawing and released to volume production once approved.
04
Volume production and delivery
Production is scheduled and traced by batch number in ERP. Shipments include REACH and RoHS declarations, material certificates and test reports.

PPAP document level and Cpk requirements are agreed per project.
