How we work
From brief to pallet in six controlled steps
STEP 01
Brief & feasibility
You send a spec — or build one in the configurator. Our engineers confirm neck compatibility, liner chemistry and line speed within two working days.
STEP 02
Design & tooling
Artwork adaptation, embossing dies and, where required, new forming tools are produced in our own tool shop to keep lead times short.
STEP 03
Sampling
First articles ship within 10–15 working days, complete with a dimensional report and material declarations.
STEP 04
Line trial
We attend your filling trial, tune application torque and document the validated settings for your production record.
STEP 05
Series production
Statistical process control on every shift, with retained samples and full lot traceability from coil to pallet.
STEP 06
Supply & stocking
Scheduled call-offs, safety stock programmes and vendor-managed inventory from our distribution network.
Sustainability
Infinitely recyclable by nature. Lighter by design.
Aluminium closures are recyclable without loss of quality — and our light-weighting programme has taken measurable material out of every cap we make.
