Quality system

Batch-to-batch consistency, controlled and traceable

The challenge with insulation materials is not a single sample. We manage the parameters that decide whether the tenth container behaves like the first.

Process control points

What we control, and how

Thickness, adhesive and resin content, breakdown voltage and dimensions are managed through defined process control points, so each batch can be inspected and traced.

Process control points
Control pointWhat we control
Thickness / grammageChecked against specification and batch records.
Adhesive / resinDot weight, resin content, volatiles and cure state.
ElectricalBreakdown voltage, insulation resistance, dielectric strength.
MechanicalTensile, elongation, flexural, compression and bond strength.
Dimensions / appearanceWidth, roll size, thickness tolerance, delamination, defects, burrs.
TraceabilityRaw-material lot, production date, inspection record, shipment lot.
Inspection stages

Incoming, in-process and final

Stage 01

Incoming inspection

Paper, film, glass cloth, aramid paper and resin are checked against specification before they enter production.

Stage 02

In-process control

Thickness, adhesive or resin content, cure state and dimensions are monitored at the defined process control points.

Stage 03

Final inspection

Electrical, mechanical, dimensional and appearance checks before packing; batch test data is retained and traceable.

Test equipment

Typical checks performed on insulation materials in our laboratory:

  • Thickness and grammage measurement
  • Breakdown voltage and dielectric strength testing
  • Tensile, elongation and flexural testing
  • Adhesive / resin content and volatiles
  • Dimensional and appearance inspection

Specific instrument models and calibration records: [INSERT TEST EQUIPMENT LIST AND CALIBRATION INFO HERE].

Documents we issue

  • Datasheet — per product, with typical values and test methods
  • COA / batch test data — on request for each shipment
  • Inspection record — retained against the shipment lot
  • Samples — for approval before bulk supply

Bulk supply is subject to the approved specification, sample and test report.

Certification status

ISO 9001, UL, RoHS and REACH certificates and third-party reports:

[INSERT CERTIFICATE NUMBERS, ISSUING BODIES AND EXPIRY DATES HERE]

We publish a certificate on this page only once the scope and validity have been verified.
