Control Cabinet Factory: 5,000 sqm Workshop, Every Unit Power-Tested Before Shipment

Factory at a Glance

Note on figures: the company restarted operations in 2020, with manufacturing built on 30 years of family experience; "300+ customers" is a cumulative figure. For qualifications and certificates, see theCertifications & Qualifications page.

Workshop Photos

Photos carry our own brand watermark (present in the original images). All can be verified on site during a factory audit.

In-process inspection and factory acceptance testing

A cabinet is not done just because assembly is finished. Components are inspected on arrival, assemblies are spot-checked during production, and the complete unit is powered up and tested before shipment — all three gates are documented.

Inspection records can ship with the order (redacted version). Ask us for the template.

Shipping and packaging

Export orders come with hard packaging requirements: load-bearing wood pallets, carton stacking, stretch film for water resistance, and proper internal cushioning. Below are our actual packing stations and finished-goods packaging.

Photos are watermarked with our own brand (the originals carry it). Packaging specifications can be executed to customer requirements.

Equipment & Accuracy: Let the Numbers Speak

"Advanced equipment" means nothing; tolerances are the commitment. The table above reflects how the factory actually works: equipment nominal accuracy and process-guaranteed tolerance are listed separately — the first is machine capability, the second is a delivery commitment.

Factory testing: every unit, no sampling

Test records don't stay at the factory — they ship with the as-built documentation package, so you have documentation for on-site commissioning and future maintenance.

Factory audit process: four steps to schedule

• ① Booking — email or message us on WhatsApp with the number of visitors and what you would like to see; for a live factory tour, just book a slot in advance;
• ② Route confirmation — Standard route: incoming materials → sheet metal → coating → assembly & wiring → factory test area; can be customized to your focus areas;
• ③ On-site verification — Original certificates, quality records, and test processes are all available to inspect and question;
• ④ Pre-shipment review — If you can't visit, we provide photos and video of the entire batch before shipment, or arrange third-party inspection.

8. Internal wiringWiring accuracy 99.8%, color coding per GB 7947
9. Enclosure assemblyDoor gap 1.5–2.5mm, gasket restored without creasing

Cabinet interior cleanup and tidy-up

Once components are mounted and wiring is complete, the cabinet interior still has to be cleaned up: route and straighten the wire bundles, put the wire duct covers back on, and leave no debris inside the cabinet. This step directly affects on-site commissioning and future maintenance.

On-site service

Shipping the cabinet is not the end of the job. We go on site to handle wiring checks, troubleshooting, and retrofit wiring at the customer's facility.
