Four export QC projects across three continents — a Thai cooker exporter, a Vietnamese water heater plant, an EU testing laboratory and an integrated cooker factory — and the working pattern behind each one.
Export QC looks different in every market: a Thai cooker exporter needs batch consistency before containers ship; a European laboratory needs certification-oriented data; a Vietnamese plant needs endurance testing across many units at once. This case study collection shows how Zhongshan Wanhe approached each project — the requirement, the solution, the equipment and the outcome — and the pattern that connects them: specification honesty, customisation without drama, and support that survives shipping.
Every gas appliance exporter faces the same fundamental question: how do you prove the quality of your product in a market you cannot see? The answer differs by region:
Consistency across every batch before container shipment
Reliability at production volume — statistically meaningful data
Certification-grade evidence that withstands laboratory scrutiny
Combined-function testing — gas + air performance on one product
What the four projects have in common: each factory needed equipment that matched its market's evidence standard — not a generic bench, but a testing solution designed around the product, the standard and the workflow.
New all-in-one test bench enables synchronous gas combustion and range hood testing. Includes expansion modules for future steam oven and sterilizer testing.
Supplied a computer + PLC controlled aging equipment with 6 independently controlled stations, letting the client verify long-term reliability before export.
EU EN-compliant boiler test bench for precise certification. Accurately measure gas tightness, thermal efficiency, combustion & exhaust temperature.
We built a complete combustion and safety QC bench for gas stoves, helping a kitchen appliance factory pass target-market certifications and export confidently.
Every project starts with the product, the standard and the market — not with a catalogue.
The quotation states test items, standards mapping, instrumentation class and utilities. What we cannot do, we say so before the order.
Production-floor operators, laboratory engineers and quality managers use the bench differently; the design follows the user.
Technical specification, acceptance test report, calibration records — the paper trail arrives with the machine.
Video commissioning, remote diagnosis, spare parts and 24-hour response — support is part of the product, not an add-on.
Batch records, certification data, endurance statistics, or combined product records — know what your buyers actually ask for.
Which standards, which test items, which instrumentation class — this mapping determines whether your data is defensible.
The machine is the easy part; the relationship decides whether the project succeeds. Look for transparent quotation, honest feasibility assessment and cross-border support.
Yes — customisation is our core work. Tell us the product, the standards you need to meet and your workflow; we return a written specification with test items and instrumentation class, typically within the 7–15 day design cycle.
Yes — video-based commissioning support, remote diagnosis, spare parts shipment and 24-hour response. For larger projects, on-site installation can be arranged.
Our gas test benches are built with LPG/NG readiness and can include gas mixing systems for multiple gas families — the gas supply configuration is specified in the quotation per your markets.
Yes — as the integrated cooker project shows, we build combined solutions that test gas functions and range hood air performance on one coordinated platform with shared data recording.
The technical specification, acceptance test report, calibration records, operation and maintenance documentation — the documentation set for your quality system and audits.
Our core is gas appliance testing, environmental chambers and related custom QC equipment. Tell us the requirement — we will tell you honestly whether it fits our engineering scope before quoting.
The acceptance test report documents the verification of each specification item at our factory before shipment. You can also arrange third-party inspection before shipment — a step we support fully.
Enquiry and specification (1–7 days), design (7–15 days), manufacturing (15–45 working days depending on customisation), then shipment and video commissioning. Every quotation states its own dates in writing.
Tell us your test standards, product parameters and customization needs. Our professional engineering team will reply with a detailed scheme and quotation within 24 working hours.
