Online factory audit

Question answered: Where is the factory and what does the site look like from outside?

Real, unstaged footage shot on 29/10/2026: the gate, office block, car park, factory building, internal road between halls, cable ladders in the yard and the entrance to the production area. First episode of the topic-based factory audit series.

Question answered: Can the factory mass-produce and export consistently?

Real footage shot on 29/10/2026: incoming coil stock, the coil-fed press line (JSD presses), press tooling and the egg-crate panel assembly area. Exported to the USA since 2020, 150,000–200,000 panels per year, export revenue of about USD 2 million; steady jobs for nearly 20 local women workers.

Question answered: What equipment are the metal parts made on, and to what accuracy?

Real footage shot on 29/10/2026: QY Laser and LF-3015GAV fibre laser cutters, CNC press brake, and an enclosed CNC board-cutting room with dust extraction. This is where drive mechanism parts and precision components are made, to an accuracy of ±0.1 mm.

Question answered: On what lines are control dampers made, and at what capacity?

Real footage shot on 29/10/2026: spot welding of parts, control damper assembly benches, roll-forming lines, coil stock and decoilers. Two dedicated lines for two air control damper ranges: low-pressure, and airtight high-pressure tested to AMCA 500-D-18. Achievable output: hundreds of thousands of dampers per year.

Question answered: How is the coating applied so that Starduct can give a 10-year colour-fastness warranty?

Real footage shot on 29/10/2026: the overhead conveyor, surface pre-treatment area and tanks, the powder spray booth and the line's control panel — the line that lets Starduct give a 10-year colour-fastness warranty.

Question answered: How are Starduct EI fire dampers made, and in what volume?

Real footage shot on 29/10/2026: frame fabrication, damper body assembly, the assembly line, finished EI dampers, actuator fitting and stretch-wrapping. Workshop output is about 35,000–50,000 dampers per year, fire-resistance classes EI 30 to EI 180; size W unlimited, H ≤ 1,950 mm.

Question answered: Where are Starduct air outlets made, and which markets do they reach?

Real footage shot on 29/10/2026: the finished air outlet store, internal handling by trolley and reach truck, and the air outlet assembly benches. Products are supplied to projects in Vietnam and 12 countries worldwide, including the United States.

Question answered: Where are Starduct VAV boxes made, and which ranges are produced?

Real footage shot on 29/10/2026: VAV box casings, the assembly line, sheet-metal equipment, boxing and forklift pallet handling. This is where the VAV single duct S-VAV-S (7 sizes, certified to AHRI 880) and the rectangular, fan-powered and reheat VAV ranges with electric heater or hot-water coil are made.

Question answered: Where are products checked and set up before they go to site?

Real footage shot on 29/10/2026: the QC office, product sample shelves, the pre-dispatch checking area, the test rig and the in-house Product Testing Laboratory. Products are checked and set up here before they go to site, and new products are developed here before being sent to third-party laboratories.

Question answered: Where are Starduct products and technologies developed?

Real footage shot on 29/10/2026: R&D engineering workstations, the component and prototype bench, and a prototype with actuators and controllers. The R&D Centre is where all Starduct products, technologies, solutions, software and platforms begin.

Question answered: Were tests really done, where, and for which models?

Single-blade insulated fire damper, 600 × 600 mm, spring-return actuator, fire-tested to EN 1366-2 at a laboratory designated by the Macau Fire Services Bureau. First side on 15/10/2026 (specimen XA52610194, actuator on the furnace side); second side on 22/10/2026 (specimen XA52610265, actuator on the unexposed side). Each test: 50 open/close cycles before the burn, then 180 minutes on the standard fire curve. Observed at the laboratory: insulation and leakage criteria met for 180 minutes on both sides. The official test report has not yet been issued and will be added when available.

Question answered: What loading and dispatch capacity does the factory have?

Real footage shot on 29/10/2026: finished goods area, packed goods awaiting dispatch, the covered goods-in and dispatch area and forklifts. 5–6 trucks can be loaded at the same time by overhead crane, forklift or loading dock, under cover or in the open; 5 dedicated forklifts with 1.5–7 t capacity.

Question answered: How are goods packed before domestic delivery and export?

Real footage shot on 29/10/2026: the packing area, carton packing, the edge-seal shrink-wrap machine, packed goods and pallets ready for domestic delivery and export.

Question answered: Is every parallel fan-powered VAV run-tested before it leaves the factory?

First dispatch for Parc Hanoi on 17/10/2026: 50 S-VAV-PFE parallel fan-powered VAV units with electric heaters. The HS500W fan speed controller (200–240 VAC) is switched on and off by the Belimo LMV-BAC, with maximum speed set on a 6-step knob; each unit is run-tested (fan and HS500W, electric heater, safety interlock) and set to Vmin/Vmax from the project schedule; VAV body and heater module are packed in separate cases; loading onto the truck.

Question answered: What does a parallel fan-powered VAV box look like once installed, and what should the operation team watch for?

S-VAV-PFE boxes (parallel fan, electric heater) hung at an office project, October 2026: suspended on threaded rods below the concrete slab, connected to primary and supply ducts; access panel labels FAN ACCESS PANEL (fan chamber, filter) and PRIMARY AIR ACCESS PANEL (primary air damper); electrical warning label on the control box. Silent video. The box at 15–24 s has a ceiling bulkhead right below its access panels — an example of wrong installation; the other boxes have clear access.
