China Top Cans Filling Machine Suppliers How to Choose?

Evaluation Dimension	What to Verify	Required Evidence or Test	Practical Benchmark	Suggested Weight	Warning Signs
Legal and Business Identity	Confirm the supplier's registered legal entity, manufacturing address, export authorization, and years in operation.	Request a current business license, factory address, company bank-account details, and a live video or third-party factory audit.	Legal entity, payment beneficiary, and manufacturing location should be consistent.	8%	Payment requested to an unrelated personal or third-party account; unclear factory ownership.
Relevant Manufacturing Experience	Assess experience with the required can format, filling product, container material, line speed, and hygiene level.	Ask for anonymized project references, machine photographs, commissioning records, and a list of compatible can sizes and products.	Supplier can demonstrate completed projects with the same or closely comparable application.	10%	Only generic equipment photos are provided; no evidence of comparable installations.
Filling Accuracy	Verify volume or weight consistency, product loss, filling temperature, foaming behavior, and the effect of product viscosity.	Conduct a factory acceptance test using the customer's product or a documented equivalent; record multiple samples at start-up and steady state.	Acceptance limits should be written into the contract and verified with calibrated measuring equipment.	12%	Accuracy is stated without a test method, sample size, product conditions, or acceptance tolerance.
Rated Throughput	Compare the guaranteed output with actual output after allowing for changeovers, rejects, cleaning, and normal production interruptions.	Request a timed production test and define acceptable reject rate, operating hours, container specifications, and product parameters.	Use guaranteed net output rather than only the machine's maximum theoretical speed.	10%	The quoted speed applies only to an ideal product, one can size, or short-duration testing.
Construction and Hygiene	Review product-contact materials, weld quality, surface finish, drainage, cleanability, guarding, and access for inspection.	Request material certificates for product-contact parts, hygienic design drawings, cleaning procedures, and photographs of internal product paths.	Product-contact areas should use documented food-appropriate materials and be designed for repeatable cleaning.	10%	Unidentified product-contact materials, inaccessible dead zones, rough welds, or poor drainage.
Controls and Electrical System	Verify control architecture, electrical standards, safety circuits, remote diagnostics, data access, and availability of replacement components.	Request electrical drawings, I/O lists, software backup arrangements, component schedules, and a demonstration of fault handling.	Drawings, parameter backups, passwords, and spare-part references should be delivered with the machine.	8%	Proprietary parts are used without documentation or the supplier refuses to provide software and electrical records.
Quality Management	Determine how incoming parts, machining, assembly, testing, calibration, and final inspection are controlled.	Review inspection checklists, calibration records, nonconformity procedures, traceability records, and quality certificates where applicable.	A documented inspection process exists and test results are linked to the machine serial number.	8%	Quality is described only as “strict” without records, procedures, or measurable inspection points.
Factory Acceptance Test	Confirm that the supplier will prove capacity, filling performance, changeover, safety functions, cleaning, and alarm recovery before shipment.	Use a signed FAT protocol covering product conditions, can dimensions, test duration, sample quantity, acceptance criteria, and corrective actions.	FAT results are documented and unresolved deviations have a written closure plan.	9%	Supplier requests final payment or shipment without a defined FAT or without objective acceptance criteria.
Installation and Commissioning	Clarify who handles mechanical installation, electrical connection, utilities, calibration, trial production, and operator training.	Request a commissioning plan, required utility list, site-readiness checklist, travel terms, training agenda, and completion report template.	Responsibilities, milestones, travel costs, and completion conditions are stated in the quotation and contract.	8%	Installation is excluded from the price and no technical site requirements are supplied before shipment.
After-Sales Response	Evaluate technical support hours, response channels, remote troubleshooting, escalation, and local service capability.	Obtain a written service-level agreement with response times, support scope, spare-part response, and escalation contacts.	Critical production issues receive a defined first response, with remote or on-site escalation procedures.	8%	Support is available only through an individual salesperson; no service process or response commitment exists.
Spare Parts and Maintainability	Assess wear-part life, preventive maintenance intervals, standardization, inventory requirements, and replacement difficulty.	Request a two-year recommended spare-parts list, exploded drawings, part numbers, maintenance schedule, and lead times.	Routine parts are identifiable, replaceable with standard tools, and available within an agreed lead time.	7%	No parts list is supplied, part numbers change without notice, or all repairs require factory technicians.
Warranty Protection	Review warranty duration, covered components, exclusions, labor, freight, response obligations, and remedies for repeated failure.	Require a written warranty clause covering defects, repair or replacement procedures, evidence requirements, and warranty start date.	Warranty terms are specific, measurable, and aligned with commissioning or accepted delivery.	7%	Warranty is verbal, excludes major components broadly, or starts before installation and acceptance.
Delivery and Documentation	Verify manufacturing schedule, packaging, export documents, manuals, drawings, certificates, and shipment responsibilities.	Request a milestone schedule, packing specification, document index, shipping terms, and responsibility matrix.	Documentation is complete before shipment or tied to clearly defined contractual milestones.	5%	Delivery dates are estimates only; manuals and drawings are promised after shipment.
Purchase Price	Compare the base machine price only after aligning capacity, can sizes, filling technology, controls, safety equipment, and included accessories.	Use an itemized quotation with quantities, specifications, exclusions, currency, taxes, packing, and payment milestones.	At least three technically comparable quotations should be normalized before price comparison.	5%	A low headline price excludes change parts, testing, commissioning, documentation, or essential safety equipment.
Total Cost of Ownership	Calculate purchase, freight, installation, utilities, labor, cleaning, consumables, spare parts, downtime, and disposal costs.	Build a five-year cost model using expected operating hours, energy consumption, maintenance intervals, reject rate, and labor rates.	Select based on cost per accepted can and expected uptime, not only initial purchase price.	10%	Supplier cannot provide energy data, maintenance assumptions, expected reject rate, or realistic operating conditions.
Commercial and Payment Risk	Check payment milestones, retention, performance security, currency exposure, change-order rules, and dispute procedures.	Use a contract with milestone payments linked to design approval, FAT, shipment, installation, and final acceptance.	A meaningful final payment remains due after successful commissioning and acceptance.	8%	Large advance payment is required without inspection rights, contractual remedies, or acceptance holdback.
Overall Decision Rule	Combine technical performance, supplier verification, service capability, commercial protection, and five-year operating cost.	Score each category from 1 to 5, multiply by the suggested weight, and document all assumptions and unresolved risks.	Shortlist suppliers scoring at least 80/100 with no critical failure in safety, FAT, warranty, or legal verification.	100%	Do not select a supplier solely because of the lowest quotation or the highest advertised speed.
