Before choosing a filling machine supplier, ask how the equipment will handle your specific product, container, production target, cleaning requirements, and future changes. Then confirm what is included in the quotation, how performance will be demonstrated, and what support is available after installation. We recommend asking for written answers tied to your product and packaging rather than relying on general claims. This guide provides a practical question checklist you can use to compare suppliers, including Xilinear, and reduce uncertainty before placing an order.

Describe the product’s characteristics, including viscosity, foaming, particulates, temperature, and whether it changes over time. Ask which filling technology the supplier proposes and why it fits those characteristics. A machine suitable for a free-flowing liquid may not be the right choice for a viscous, foaming, or particle-containing product. If the formulation varies by batch, ask what operating range the supplier can support and what adjustments may be required.
A qualified supplier should be able to identify the information needed to assess the application. Ask whether they require representative product samples, container drawings, cap or closure details, and the intended fill volume. Confirm that the assessment covers the actual container material and shape, since container stability and opening geometry can affect handling and filling. If you have multiple SKUs, provide the full range rather than evaluating the machine against only one format.
Ask the supplier to define the proposed fill-accuracy target, the test method, and the conditions under which it applies. For example, you might specify a target such as “±1%” for a particular fill volume, but the supplier should confirm whether that target is achievable for your product and process. Also ask how many containers will be assessed, how results will be recorded, and what happens if the agreed acceptance criteria are not met. Do not treat a general accuracy figure as a guarantee unless the product, container, and test conditions are documented.
Ask for the expected output in containers per minute using your product and packaging, not only a machine’s theoretical maximum. Confirm whether the stated rate includes container feeding, indexing, filling, and any other operations included in the proposed scope. Ask what conditions could reduce output, such as product behavior, container shape, or frequent format changes. For planning, distinguish the target production rate from any maximum rate quoted by the supplier.
Ask which parts need to be changed or adjusted when switching between products, fill volumes, or container formats. Request an estimated changeover time in minutes for a clearly defined changeover and ask what tasks that estimate includes. Check whether tools, stored settings, cleaning steps, or operator training are needed. If you run short batches or many SKUs, changeover requirements can matter as much as nominal filling speed.
Provide details about upstream and downstream equipment, available floor space, container flow, utilities, and control requirements. Ask the supplier to identify interface assumptions and any equipment or modifications that are excluded from the proposal. Confirm how the filler will coordinate with conveyors, capping, labeling, or inspection equipment where applicable. A layout review can help reveal integration questions before the machine is manufactured or installed.
Ask which product-contact parts require manual cleaning, which cleaning methods are supported, and whether the machine is designed for a particular cleaning process. Do not assume that a machine is suitable for a specific washdown or clean-in-place procedure unless the supplier confirms it for the proposed configuration. Request cleaning instructions, maintenance intervals, and a list of routine service tasks. If product changeovers create a contamination risk, discuss your cleaning and verification requirements early.

Ask the supplier to identify the materials used for product-contact components and explain how they match your product and operating conditions. Request the documentation relevant to your project, such as operating and maintenance manuals, electrical drawings, parts lists, and material information where available. If your facility or market requires particular standards or records, state those requirements before quotation. The supplier should clarify what documentation they can provide rather than relying on broad, unspecified compliance claims.
Ask for a written breakdown of the machine configuration, included accessories, controls, installation, commissioning, training, and packaging for shipment. Confirm which items are optional or excluded, including line integration, format parts, freight, and on-site services. Request the quoted lead time in weeks and ask when that schedule begins, such as after drawing approval or receipt of required samples. A clear scope makes it easier to compare offers on equivalent terms.
Ask what the warranty covers, when it starts, and which conditions or exclusions apply. Confirm how technical support is accessed, what information is needed to diagnose an issue, and whether spare parts are available for the proposed model. Ask whether operator or maintenance training is included and whether it is delivered remotely or on site. Response arrangements and service availability should be confirmed for your location rather than assumed from a supplier’s general description.
Discuss possible changes such as new container sizes, additional products, increased output, or integration with other equipment. Ask which adaptations the proposed machine can accommodate and which would require new parts or engineering work. A supplier should explain the limits of the quoted configuration as well as its flexibility. This helps you avoid paying for capacity or options you do not need while identifying upgrades that may matter later.
Use the same product brief and question list with every supplier. Record each response as confirmed, conditional, or not included, and attach the supporting specification or quotation where possible. This creates a more useful comparison than relying on broad descriptions such as “high speed” or “easy to clean.” If a supplier cannot answer immediately, ask what information is needed and when the answer can be confirmed.
| Evaluation area | What to document |
|---|---|
| Application fit | Product properties, container range, fill volumes, and proposed filling method |
| Performance | Target containers per minute, accuracy criteria, and test conditions |
| Operations | Cleaning method, changeover steps, routine maintenance, and training |
| Commercial scope | Included equipment, exclusions, delivery schedule, warranty, and support |
Before approving an order, agree on acceptance criteria that can be checked during a product-specific test or commissioning process. Define the product, container, target fill, operating conditions, sample size, and records required for the review. Where a test cannot be completed before shipment, discuss what can be verified in advance and what will be checked at your facility. Keep the agreed criteria in the purchase documentation.
The best supplier is not necessarily the one with the lowest initial price or the highest headline speed. It is the supplier that can explain how its proposed configuration fits your product, containers, output needs, and operating requirements—and document what is included. For Xilinear, buyers can begin an application discussion by sharing their product type, container details, target fill volume, expected output, and facility requirements. This information helps frame a relevant machine proposal and identify technical questions that should be resolved before quotation.
Your next step is to prepare a short application brief, send the same information to shortlisted suppliers, and ask them to respond in writing to the questions above. Compare confirmed specifications, test conditions, commercial scope, and support arrangements before making a decision. If you are evaluating a filling machine for a specific product or packaging format, contact Xilinear with your requirements to discuss a suitable solution and clarify the information needed for a proposal.
