CORE CAPABILITIES · IN-HOUSE PROCESSES

From tooling to inspection,
the critical steps stay in-house

We focus on the processes that determine cold plate quality: mold development, stamping, laser cutting, 3600T die casting, CNC machining and inspection. Welding, brazing and surface treatment are completed with qualified supply-chain partners.

Cold plate mold development01

MOLD DEVELOPMENTCold plate tooling

In-house forming molds, fixtures and gauges, with DFM review and fast tool correction for sample iterations.

SERVICE · HOW WE WORK

Two ways to work with us, one manufacturing team

Choose a proven standard cold plate, or send drawings and samples for a build-to-print program from tooling through volume delivery.

Standard products

Select from LCP-A, LCP-B and LCP-C formats for EV, ESS, commercial vehicle and motor/controller cooling.

  • Model selection
  • Sample approval
  • Volume supply

Build to print

Send drawings, samples or a technical agreement; we handle DFM review, tooling, forming, machining and inspection.

  • Drawing review
  • Tooling
  • Sample validation

Rapid prototyping

Short-run samples and pilot batches for new platforms and design iterations, without waiting for final tooling.

  • Fast response
  • Pilot runs
  • Design iteration

Volume delivery

Scheduled production with final inspection and documented results, plus ongoing process improvement.

  • Production planning
  • Final inspection
  • Continuous improvement
Dimensional inspection
CMMKey dimensions and features
QUALITY · PROCESS CONTROL

Built into the process,
verified before delivery

Quality is controlled from incoming material through first-article approval, in-process inspection and final inspection. Critical dimensions, appearance and form are checked to drawing; records remain with each batch.

CMM inspection

Key dimensions, hole positions and geometric features measured against the drawing.

Appearance & flatness

Visual inspection of every part; flatness and critical features checked as specified.

Leak testing (as required)

Air-tightness or pressure testing is performed per project agreement.

Records & traceability

Inspection data is archived by batch for project traceability and review.
