Why we test in-house
Routine checks belong on the line, not in a report you have to ask for months later. Leak, pressure, burst and dimensional checks are the ones that catch a problem while the batch is still on the floor, so we keep those instruments in the plant and run them per batch.
This is also the honest boundary of what an in-house laboratory means. It does not replace accredited third-party testing. For heavy metals, PFAS and food-contact compliance we still send samples to external laboratories — those reports are listed on the certificates page, and the blog explains how to read them. The laboratory below is what sits between the two: fast enough to check every shift, specific enough to hold a specification.
The instruments

What each instrument is used for
| Water-bath leak test tank | Every can is immersed after crimping. This is the 100% leak check already described on the certificates page — not a sampled check. |
|---|---|
| Pressure test rig with precision gauge | Pressure testing, sampled per batch and recorded against the batch number. |
| Digital readout test station | Digital readout unit with a can and valve fixture. |
| Manual pull test stand | Digital travel readout on a handwheel-driven stand. |
| Height gauge | Height checks on formed can bodies, against the drawing for the size being run. |
| Vision measuring machine | Non-contact measurement on a glass stage — diameter, shoulder geometry and print position. |
| Test chamber | Stainless chamber with digital control panel. |
| Vacuum drying oven | Vacuum oven with pressure gauge and viewing window. |
| 3D printer | Enclosed printer. |
Photographs show our own equipment. Each line describes the instrument itself rather than claiming every test it might be used for — if you need the specific application for a particular machine, ask and we will confirm it against the process it is set up for.
How this fits your order
- Every can, not a sample. Leak testing is a 100% check — one can at a time through the water bath.
- Recorded against your batch. Pressure and burst results are logged with the batch number, so a question months later can be traced back to the cans that were actually produced.
- Evidence you can hold. If your customer or customs broker needs documentation, tell us the batch reference and the document required and we will retrieve it rather than send a generic certificate.
- Where we stop. Anything requiring accreditation goes to a third-party laboratory. We tell you which is which up front.
