Build a format matrix before selecting the machine
The key contract-bottling question is not simply “Can the machine cork bottles?” It is which approved formats the machine must run, how often they change and how the operator proves that each changeover is correct. Create a matrix that separates live contracted formats from possible future opportunities.
| Format item | Why it matters for contract bottling | Evidence to hold |
|---|---|---|
| Bottle family | Different base shapes, heights and neck finishes can require support and guide changes. | Drawing, sample, supplier reference and approved support setting. |
| Closure family | Customer-specific tops may have different feed and marking behaviour. | Closure samples, shank measurements and top-finish acceptance photographs. |
| Batch length | Short campaigns may not justify lengthy feeder tooling or rotary changeover. | Expected run quantity, schedule and acceptable setup time. |
| Quality standard | Premium brands may require a tighter visual standard than commodity packs. | Finished-height, top-marking and reject criteria for each customer. |
Changeover evidence is a commercial tool
A clear changeover record helps protect both the contract bottler and the brand owner. It shows which parts were fitted, which settings were used and which samples were approved before production. It also speeds up support if a later batch behaves differently.
Choosing a practical architecture
For varied campaigns, a controlled pneumatic or linear route may be more useful than a complex high-speed line. For repeated high-volume contracts, automatic feeding and rotary transfer can be justified when the format list is stable. The right answer depends on actual good output after setup, stoppages, rejects and changeover—not on a nominal machine category.
Review machine options, changeover planning and quotation cost factors before preparing a multi-format enquiry.
