1. Business Overview
This business focuses on manufacturing HVAC components used in ventilation systems for residential, commercial, and industrial buildings. The two main products are:
- Straight round air ducts (high volume, lower margin)
- Elbows and fittings (higher margin, project-based revenue)
2. Production Technology
Spiral Duct Production
Steel coils are formed into spiral round ducts using automated forming equipment and cut to required lengths.
Elbow Production
Elbows and fittings are made from segmented metal sheets, formed into curved shapes and assembled into finished components.
3. Minimum Required Equipment
1. Spiral Tube Forming Machine
Example: TF1602 Spiral Tube Forming Machine
- Produces round ducts from 75 mm to 1500 mm
- High-speed continuous production
- Automated cutting system
Estimated price: $30,000 – $80,000
2. Elbow & Fitting Machine
Example: Gorelocker SGWT-1250
- Produces elbows (45°, 90°)
- Manufactures reducers and offsets
- High flexibility for custom fittings
Estimated price: $8,000 – $25,000
3. Metal Cutting Equipment
- Manual or semi-automatic shear
- Band saw for precision cutting
Estimated price: $1,000 – $5,000
4. Beading Machine (Optional but Recommended)
Adds reinforcement ribs to improve duct rigidity.
Estimated price: $1,000 – $3,000
5. Flange Machine (Optional for Expansion)
Used to create TDF/TDC flanges for fast installation and duct connection in large construction projects.
Estimated price: $10,000 – $25,000
4. Initial Investment
Minimum Setup
- TF1602 Spiral Machine
- SGWT-1250 Elbow Machine
- Cutting + basic tools
Total: $50,000 – $120,000
Full Production Setup
- TF1602
- SGWT-1250
- TDF/TDC flange machine
- Cutting + beading equipment
Total: $80,000 – $150,000
5. Profitability
| Product | Profit Margin |
|---|---|
| Straight ducts | Low to medium |
| Elbows & fittings | High |
Typical monthly revenue ranges:
- Small workshop: $3,000 – $15,000
- Medium operation: $15,000 – $50,000+
6. ROI (Return on Investment)
Average payback period: 6 to 24 months
7. Key Success Factors
- Combination of duct + fittings production
- Strong supply contracts with installers and construction companies
- Efficient production workflow
- Focus on elbows and custom fittings for higher margins
8. Business Logic Summary
- TF1602 = volume production (ducts)
- SGWT-1250 = profit generation (fittings)
- TDF/TDC = access to large construction projects
