Selection process
Start with the closure, then specify the machine.
A screw cap, ROPP closure, trigger sprayer, pump or push-on lid can all need a different capping head, feed route and bottle handling system. Use this guide to narrow the options before Lancing confirms the final specification.
- Cap detailsConfirm cap type, diameter, height, liner and neck finish.
- Bottle handlingCheck bottle diameter, height, material, filled weight and stability.
- Output targetSet bottles per minute and decide manual placement, semi-auto or fully automatic feed.
- Feeding routePlan bowl feeders, elevators, pump-cap orientation and conveyor layout early.
- Quality checksConfirm torque, leak performance, ROPP pilfer-band finish or cap seating force.
- Line integrationAllow for filling, labelling, coding, conveyors, guarding and accumulation.
Quick comparison
Common capping routes
| Closure type | Likely machine route | Key checks |
|---|---|---|
| Screw caps | Chuck, compact inline, belt or spindle capping | Torque, cap start, bottle stability, cap feed |
| ROPP aluminium caps | Semi-automatic, automatic or rotary ROPP capper | Neck finish, roller setup, pilfer band and liner compression |
| Pump caps | Automatic pump capper or pump-cap feeding system | Orientation, dip tube handling, closure height and bottle support |
| Trigger sprays | Trigger sprayer capping machine | Long trigger head orientation, bottle shape and torque |
| Push-on lids | Cap pressing machine | Seating force, cap presentation and container support |
What information is needed for a useful capping quote?
Cap type, cap diameter, bottle height, bottle diameter, product type, target output, torque target, filling/labelling integration needs and available space.
When do I need automatic cap feeding?
Automatic cap feeding becomes important when output, operator time, orientation or repeatability becomes a bottleneck. Bowl feeders and cap elevators should be specified early.
What affects ROPP capping quality?
Closure and neck compatibility, roller pressure, thread roller setup, head pressure, liner compression, pilfer-band tuck, bottle support and cap feed consistency.
Specification pathway
Use the buying guides in the order a capping project is specified.
A capping project should be checked in sequence: closure type, bottle stability, torque or seating requirement, cap presentation, conveyor control and the evidence needed for a reliable quotation. The pages below add detail without changing the existing machine range or application pages.
Machine route
Model and route matrix
Use a qualitative model matrix to shortlist semi-automatic, chuck, spindle, inline, rotary, ROPP and cap-feeding routes without unsupported speed claims.
View the model matrix →Trials and feeders
Trial and cap-feeder evidence
Prepare the practical evidence Lancing needs: cap samples, bottle stability checks, feeder orientation, layout photos and production constraints.
Prepare trial evidence →Project evidence pack
Use the guides to build a specification pack before quoting.
The strongest capping enquiries usually include the same evidence an engineer needs for selection: bottle and cap samples, closure dimensions, quality criteria, production context and a simple line layout. The guide pages are designed to collect that information before a machine is selected.
Samples
Confirm the closure in the real container.
Use the sample checklist to capture bottle material, neck finish, cap type, liner, tamper feature and problem examples where available.
Bottle sample guide →Line layout
Show how bottles arrive and leave.
Conveyor height, infeed control, accumulation and downstream labelling can change whether a capper should be compact, inline or integrated into a full line.
Line layout guide →Acceptance
Define the pass/fail checks early.
Torque, cap height, leak risk, tamper-band formation and visual alignment should be agreed before committing to final machine selection.
Acceptance testing guide →Project delivery guides
Move from machine selection to a controlled specification, installation and acceptance process.
Closure choice is only the first stage. A dependable project also defines what the machine must do, how it will fit the production area, how unacceptable packs will be detected and what evidence will be used at acceptance.
URS
Define the requirement before comparing proposals.
Use a user requirement specification to record pack formats, output basis, interfaces, utilities, changeovers, documentation and acceptance evidence.
Capping machine URS guide →Site readiness
Check access, services and layout early.
Delivery routes, floor space, conveyor elevations, power, air, extraction or drainage needs and operator access should be confirmed before installation.
Site-preparation checklist →Inspection
Decide how the line responds to a bad closure.
Agree the detectable fault, sensor limitations, reject mechanism, confirmation method and line response before the controls scope is frozen.
Inspection and reject guide →Safety closure
Treat child-resistant packaging as a pack system.
The closure, container and instructions must be managed together. Machinery selection cannot replace the evidence required for the finished packaging system.
