Quality standards

Control the dimensions. Protect the performance.

SGEI combines defined material properties, dimensional inspection, and sample confirmation to support consistent contact performance in production.

Quality system

Repeatable work begins with a defined specification.

The company catalogue identifies an ISO 9001 quality system. For each custom product, the practical control plan begins with a clear drawing, material selection, dimensional requirements, and an approved sample.

Dimensional control

Rivet-contact tolerance reference.

Catalogue reference based on JB/T 10383-2002. Project drawings and agreed acceptance criteria remain the controlling specification.

Head diameter — D± 0.05 mm
Head thickness — T± 0.05 mm
Composite layer — S± 0.03 mm
Shank diameter — d+0 / -0.05 mm
Overall length — L± 0.10 mm
Sphere radius — SR2–3 × D
Mould angle — α7–9°

Inspection flow

Four gates from requirement to supply.

  1. 01

    Requirement review

    Drawing, application, electrical duty, material, quantity, and acceptance needs.

  2. 02

    Material confirmation

    Alloy composition and contact structure selected for the intended switching duty.

  3. 03

    Dimensional inspection

    Head, shank, layer, length, surface, and application-specific characteristics checked.

  4. 04

    Sample approval

    Customer confirmation establishes the reference for production supply.
