Choosing used PET and beverage production equipment starts with the product, packaging format and required output. The right machine must also suit your process, tooling, factory utilities and the equipment before and after it. A manufacturer's name or headline speed alone is not enough to establish suitability.

This guide explains what to check when buying preform injection moulding systems, PET blow moulders, closure production equipment, fillers, labellers, packaging machines and complete beverage lines.

1. Define what you need to produce

Prepare a short production specification before comparing machines. Include:

Product: water, carbonated drinks, juice, dairy, edible oil or another product, including filling temperature and any hygiene or thermal treatment requirements.
Container: PET, glass or aluminium; volume, dimensions, shape and neck or can-end specification.
Material and components: preform weight and design, resin specification, intended recycled PET content, closures and labels.
Output: required saleable units per hour for each format, production hours and expected changeover frequency.
Finished pack: bottles or cans per pack, shrink film or carton, tray requirements and pallet pattern.
Project constraints: budget, installation country, available floor space, utilities and required start-up date.

There is no single capacity band that suits every project. Requirements can range from small specialist production to high-output continuous operation.

2. Match the equipment to the process

Preform injection moulding: Preform weight and neck finish, mould cavitation, achievable cycle, plasticising capacity, tooling compatibility, resin drying and cooling.
PET stretch blow moulding: Exact model and generation, bottle format, preform design, neck handling, mould compatibility, required process and compressed air.
Single-stage injection stretch blow moulding: Container and resin requirements, complete tooling set, production cycle and machine configuration.
Closure production: Closure drawing and resin, compression or injection process, tooling, cycle and any slitting, folding, lining or inspection equipment.
Filling and capping: Product characteristics, container, fill temperature, carbonation, hygiene requirements, filling method and closure system.
Labelling: Label technology, container material and geometry, label dimensions, application speed and format parts.
Packing and palletising: Pack style, packs per minute, film or carton specification, pallet pattern and handling of each format.
Inspection, conveying and utilities: Inspection task, container handling, accumulation, controls integration, air, cooling, power and water requirements.

3. Compare capacity on a consistent basis

Maximum rated output is a starting point; sustainable output for your product is the figure that matters. Check whether a quoted speed is a mechanical maximum, a demonstrated production rate or a supplier's estimate. Establish the format and operating conditions behind it.

Preform injection moulding systems

Theoretical output in preforms per hour equals active mould cavities × 3,600 ÷ cycle time in seconds. For example, 72 active cavities running a 9-second cycle give 28,800 preforms per hour before downtime and rejects. This calculation does not establish that a particular system can achieve that cycle with your preform.

Check preform weight, wall thickness, mould and hot runner compatibility, shot capacity, plasticising capacity and cooling performance. Identify the exact system generation and configuration; a machine's clamping tonnage alone does not determine preform output.

PET stretch blow moulders

Always identify the full model and generation, for example Sidel SBO 10 Universal, SBO 10 Universal2 or SBO 10 Matrix. The same cavity count across different generations does not imply the same production capacity.

As an initial screening guide, older Sidel generations commonly fall around 1,200–1,600 bottles per hour per cavity, while many Universal configurations are around 2,000. Matrix configurations can run faster. These are indicative generation-level figures, not verified ratings for every machine or bottle. Confirm the exact model's documentation and installed options before assigning a capacity.

If preform weight or wall thickness is unavailable, use the documented maximum output for the specific model as a provisional comparison and state the assumption. Request those preform details, the bottle drawing and process requirements before confirming production suitability. Hot-fill and other specialised configurations require separate assessment.

When a buyer requests a specific model and generation, start with that machine. Compare the immediately lower and higher capacity options within the relevant range if alternatives would help meet the requirement.

Fillers, labellers and packaging equipment

Confirm speed for your actual product, container and label or pack format. A filler rated for water is not automatically suitable at the same speed for a different product or filling process. A labeller's performance depends on the application and container; a packer's output must be expressed in packs per minute as well as containers per hour.

For example, 20,000 containers per hour in six-container packs require approximately 55.6 packs per minute before allowing for losses or operating margin. Compare that demand with the packer's demonstrated capability for the proposed format.

4. Check process and format compatibility

Matching nominal speeds does not make machines compatible. Check the interfaces between each stage:

Preform neck finish, bottle neck and closure specification must correspond.
Moulds, neck handling parts, starwheels, guides, filling and capping components must suit the proposed container.
Roll-fed, self-adhesive, cold-glue and sleeve labellers require different materials and application systems.
Filling, cleaning and any pasteurisation or sterilisation process must suit the product and packaging.
Conveyors, transfer heights, accumulation and controls must support the planned line arrangement.

A Sidel Blow Combi integrates blowing with filling and capping, with bottles transferred directly from the blower to the filler rather than through an air conveyor. Assess the integrated configuration and its supported products and formats when comparing it with standalone machines.

5. Assess the complete supply scope

A used machine may be offered alone or with essential auxiliaries. Obtain an itemised scope of supply and identify what must be purchased separately.

Preform systems: mould, hot runner, post-mould cooling and handling, resin loader and dryer, chiller and relevant controls.
Blow moulders: preform feeder, moulds, format parts, compressor, air treatment and cooling equipment.
Closure lines: moulding machine, tooling and downstream finishing, inspection and handling equipment.
Filling and packaging: product preparation, cleaning system, cap and label handling, conveyors, format parts and downstream equipment.
All categories: manuals, electrical drawings, software backups where available, spare parts and any required lifting or loading tools.

Do not assume that an accessory is included because it was supplied with the machine when new. Confirm each included item in the sale documentation.

6. Inspect condition and verify the machine's identity

Record the nameplate, serial number, manufacture year, exact configuration and any documented upgrades. Compare declared operating hours with the controls and maintenance records; distinguish total hours from production or load hours where applicable.

Whenever possible, inspect the equipment running with a relevant format. Review product quality, achieved output, alarms, wear, leaks and changeover requirements. Establish the availability of technical support, parts and tooling for that particular generation.

An overhaul should have a clear scope and date, supported by records. A recent overhaul does not automatically mean every component or control system has been renewed.

7. Calculate the installed cost and line output

Compare the purchase price together with dismantling, export packing, transport, tooling changes, utilities, installation, commissioning and initial spare parts. Ask for consumption figures with their test conditions so that air and electricity requirements can be compared meaningfully.

A complete line's output is constrained by the slowest effective stage, with additional losses from stoppages, rejects and changeovers. Check the balance between machines and the available accumulation rather than assuming that identical nameplate capacities guarantee the desired finished output.

Frequently asked questions

Can a used machine run a bottle or pack format it has never produced?

Possibly, provided its technical limits and process suit the new format. New tooling, handling parts or other modifications may be required. Check the drawings and proposed changes before purchase.

Should I choose equipment by brand or production requirement?

Define the production requirement first, then compare suitable models, generations and configurations. Brand preference, local service support and existing factory equipment can help narrow the selection.

Can you recommend equipment when there is no suitable machine currently listed?

Contact PETmachinery with your requirement. We can discuss suitable equipment types and sourcing options. Technical suitability and current availability should be assessed separately.

What should I send with my enquiry?

Send the product, container or preform drawings, neck or closure specification, required output, preferred equipment age, budget, installation location and target start-up date. For a replacement machine, include details of the existing equipment and line interfaces.
