EV battery cold plates · Manufacturing & custom processing

Quality

Cold plate delivery quality depends on control at incoming material, every process step and final inspection. We inspect and test to drawings and project agreements: key dimensions, appearance and flatness are checked batch by batch, leak testing and other items are performed as required, and inspection records are traceable with each shipment.

QUALITY POLICY

Build quality into the process

We see quality as the result of design and process control, not something inspection can add at the end. From incoming inspection and first-article approval to in-process checks and final inspection, requirements are broken down to each process step and recorded so they can be traced.

Customer focus

Inspection items and acceptance criteria are set from the thermal design input and assembly requirements, not from generic tolerances alone.

Process control

Confirmation points at incoming, first article, in-process checks and final inspection; non-conforming batches are held and recorded immediately.

Continuous improvement

Inspection data and customer feedback drive process improvements so the same issue does not recur.

Supply-chain collaboration

Welding, brazing and surface treatment are carried out with qualified supply-chain partners, controlled to drawings and acceptance agreements.

PROCESS CONTROL

Four inspection gates, recorded batch by batch

From incoming material to shipment, every inspection point has a matching record. Drawing revision, inspection items and results can be looked up for each batch, which helps customers trace issues and improve over time.

Incoming inspection

Aluminum sheet, consumables and other materials are checked against drawings and standards for material, size and appearance; non-conforming batches are not accepted into stock.

First-article approval

The first part of each batch or mold is confirmed for dimensions, appearance and key features; production continues only after approval.

In-process inspection

Dimensions and appearance are checked by process step and frequency; deviations are corrected in time and the actions are recorded.

Final inspection

Quantity, appearance, dimensions and agreed inspection items are checked batch by batch; records are issued with the shipment after acceptance.

TESTING CAPABILITY

Testing to agreement, with traceable data

Inspection items are defined by drawings, application and customer agreements, covering dimensions, appearance, flatness and leak tightness. Where needed, we support material and process validation together with the customer.

CMM inspection

Key dimensions, hole positions and port locations are measured on a CMM and the actual values recorded against the drawing.

Visual inspection

Scratches, deformation, burrs and surface defects are checked and dispositioned per project agreement.

Flatness inspection

Flatness of mounting and sealing surfaces is controlled to ensure proper fit and sealing in assembly.

Leak testing (as required)

Leak and pressure-related tests are performed to project agreements to confirm sealing reliability.

Material & process support

With qualified supply-chain partners, we confirm inspection requirements for material, welding and surface treatment.

Reports & traceability

Inspection records are linked to batch and drawing revision, supplied with the shipment and fully traceable.

TRACEABILITY

One file per plate, from incoming material to after-sales

Each batch has a searchable record linked to drawing revision, incoming batch, process records, inspection data and shipment information. Customers can look up a batch quickly and, if an issue occurs, trace it to the specific process step.

STEP 01

Raw material

Incoming batch, specification and inspection records are filed and linked to supplier and drawing revision

STEP 02

Process

First-article approval, in-process records and process parameters are archived per work order

STEP 03

Finished part

Dimensional, visual, flatness and, where required, leak test data are recorded per batch

STEP 04

Shipment

Full final inspection; quantity and batch are linked to the customer order for quick retrieval

STEP 05

After-sales

Customer feedback and corrective actions are written back to the file, driving process and inspection improvements

Our quality commitment: every batch shipment can be accompanied by its inspection records; inspection items are performed to agreement and the results are traceable.
