SBKJ machine videos — sent on request within 12 hours

How the SBKJ video library works

SBKJ records new HD demo footage every time a major machine completes its FAT. The footage is filmed in the test bay at the Jiangyin factory using actual production coil and the actual PLC program that ships with the machine — not stock cutaways and not marketing reels. Every clip is dated, tagged with the machine serial, and stored against the buyer's engagement file so SBKJ can send the most current and most relevant version when you ask. The list below names the videos that are currently available; the request flow is at the bottom of the page.

Rectangular duct production — auto duct lines and TDF

The rectangular duct video set covers the SBKJ flagship auto lines and the TDF flange ecosystem that surrounds them. These are the most-requested clips on the library because the auto duct line is usually the highest-value single decision in a buyer's investment plan.

• SBAL-V auto duct line — full coil-to-duct cycle. Demonstrates the complete production cycle from coil load through CNC dimension setting, Pittsburgh lock forming, notching, folding, beading and TDF output. Recorded at the design throughput of 2,500 m²/day with a single operator. See the SBAL-V product page for the full specification.
• SBAL-III auto duct line — mid-volume cycle. Same coil-to-duct cycle on the smaller SBAL-III at 1,200 m²/day for buyers with lower throughput targets or constrained workshop footprint.
• SBEM-1250 rectangular duct line. The compact rectangular duct line for buyers who need flexible duct sizing and lower volume. See the SBEM-1250 product page.
• TDF flange forming machine. Continuous TDF profile rolling demo, including changeover and seam quality close-ups. See the TDF flange product page.
• Pneumatic TDF corner inserter. The bench-top tool that completes the TDF connection at the duct corners — demoed alongside the TDF roll-former for buyers who run a complete TDF cell.
• Lockformer — Pittsburgh, S-cleat and drive cleat. The standalone lockformer that handles the seam profiles needed for hand-built duct alongside or instead of an auto line. See the lockformer product page.

Spiral and round duct production — SBTF tubeformers

The spiral tubeformer family is the second-most-requested video set, especially for buyers in commercial HVAC, dust extraction and industrial ventilation markets where round duct dominates.

• SBTF-1602 spiral tubeformer — full diameter range demo. Demonstrates the Φ80–1,600 mm range with the flying shear cutting at full line speed, plus seam quality close-ups for buyers concerned about leakage class. See the SBTF-1602 product page.
• SBTF-1500 spiral tubeformer. Same demo set on the smaller-footprint SBTF-1500 for buyers with constrained workshop length or lower diameter range. See the SBTF-1500 product page.
• SBTF-2020 spiral tubeformer. The large-bore tubeformer for industrial ventilation buyers running diameters up to Φ2,000 mm. See the SBTF-2020 product page.
• Spiral elbow forming machine. Demonstrates segmented elbow forming, gore cutting and welded elbow assembly for buyers who need to make their own fittings rather than buy them in.
• Roll bending machine. Plate roll demo for arc and elbow forming alongside the spiral tubeformer.

Cutting, welding and ancillary equipment

SBKJ supplies cutting and welding equipment as part of the wider HVAC duct factory tool kit. These videos are usually requested by buyers who are building a greenfield factory and need to evaluate the complete tool set rather than a single machine.

• CNC plasma cutter — fitting blank cutting. Plasma cutting demo for fitting blanks, branch tees, gore segments and offset patterns. See the plasma cutter product page.
• Coil slitting line. Demonstrates coil-to-strip slitting for buyers who feed downstream tubeformers from master coil rather than slit coil.
• Sheet metal shearing. Hydraulic shear demo for buyers cutting sheet to size for hand-built duct or for fitting blanks.
• Aluminium flexible duct forming machine. Demonstrates continuous flexible duct production for the residential and light commercial market.
• Angle flange drilling machine. Drilling demo for buyers who run a traditional angle flange line alongside or instead of TDF.

Factory and company walk-throughs

The factory walk-through is the second-most-useful video for a buyer who can't travel, after the machine demo itself. It shows the workshop layout, the assembly bay, the test bay and the export packing area — the same route a visiting buyer would walk on a factory tour.

• Jiangyin factory walk-through. Current walk-through covering all three production halls, the test bay and the dispatch yard. See the factory capability page for the corresponding write-up.
• SBKJ company overview. Short company film covering the history since 1995, the engineering team and the global installed base in 80+ countries. See the about page.
• Factory acceptance test — sample session. A recorded FAT session on a recently delivered SBAL-V line, useful for buyers who want to know what to expect before they travel. See the quality control page for the FAT procedure.

How to request a video — what to include

Send a short email or WhatsApp message naming the videos you want from the list above. To get the most relevant clips, include the following:

• Machine family — SBAL-V, SBEM, SBTF spiral tubeformer, TDF flange, lockformer, plasma cutter, etc.
• Throughput target — daily or hourly output, in m² for rectangular duct or in linear metres for spiral.
• Diameter or duct size range — for spiral, the Φ range; for rectangular, the smallest and largest duct cross-section.
• Coil gauge — the thickness range you plan to run, in mm or in gauge.
• Project country — for voltage, certification (CE, AS/NZS, SMACNA) and language considerations.

SBKJ engineers reply to every request within 12 hours with a WeTransfer or direct download link, the runtime, the recording date, the machine model captured, and a short note describing the operating conditions in the clip. Buyers who are running a procurement-team evaluation can request the full set in one go and the SBKJ team will package it as a single download for distribution inside your business.

Frequently asked questions

Why are SBKJ machine videos sent on request rather than published on the website?

SBKJ records HD demo footage of every machine and updates the library after every FAT, but the footage is shared on request rather than published openly so the company can match the right video to the buyer's actual project. A request lets SBKJ send the SBAL-V cycle that fits your throughput target, the SBTF program that matches your diameter range, or the factory walk-through that focuses on the assembly bay relevant to your line.

How quickly does SBKJ reply to a video request?

SBKJ engineers reply to every video request within 12 hours. The reply includes a download link or WeTransfer drop, the runtime, the recording date, the machine model captured, and a short engineering note describing the operating conditions in the clip.

What should I include in a video request?

Include the machine family you are evaluating (SBAL-V, SBEM, SBTF spiral tubeformer, TDF, lockformer, etc.), your throughput target or diameter range, the gauge of coil you plan to run, and your project country. The more specific the request, the more relevant the clip SBKJ can send.

Can I see the SBKJ factory in a video walk-through?

Yes — SBKJ keeps a current factory walk-through on file showing the structural steel hall, the assembly bay, the test bay, the export packing area and the dispatch yard. It is sent alongside any machine demo on request.

Are SBKJ videos suitable for a remote (video) FAT?

Yes. SBKJ runs full video FAT sessions for buyers who cannot travel to Jiangyin. The session is scheduled at order confirmation, the buyer joins live (Zoom, Teams or WeChat), and the SBKJ engineer walks the machine, runs the program against the buyer's nominated coil, and answers questions in real time. A recording of the video FAT is sent afterwards as part of the document pack.
