HVAC Duct Pittsburgh Lock Forming Machine | Sheet Metal Lockformer

1. Product Overview & Key Advantages

The Standard Duct Lock Forming Machine is an essential piece of equipment for the HVAC (Heating, Ventilation, and Air Conditioning) duct fabrication and sheet metal processing industry. Designed for high efficiency and precision, our lockformers can smoothly process galvanized steel sheets with thicknesses ranging from 0.3mm to 1.5mm (up to 2.0mm for heavy-duty models).

Why Choose Our Lock Forming Machines?

Multi-Profile Versatility: Advanced models like the LCD4C and LC-12M (with 9 stations) can process up to 6 different kinds of profiles, including Pittsburgh seam, S-cleat, drive cleat, and snap lock.
High Portability for Site Use: Featuring a compact and lightweight design, our machines are easy to move, making them perfectly suitable for both factory workshops and on-site construction projects.
Custom Engineered Solutions: If your project requires non-standard profiles, our engineering team can design special machines tailored to your exact specifications.

5. Frequently Asked Questions (FAQ)

Q1: What materials can this lockformer process?

A: Our standard machines are optimized for galvanized steel sheets (0.3-1.5mm). We also offer specific models like the LC-15SR designed exclusively for stainless steel processing.

Q2: Is the machine easy to transport to a construction site?

A: Yes, the machine is designed to be lightweight and portable, equipped with lifting points for easy transportation to job sites for on-site duct fabrication.

Q3: Can I customize the roller profiles?

A: Absolutely. While our machines cover standard HVAC profiles (Pittsburgh, S-cleat), we provide OEM/ODM services to design custom rollers for your specific profile needs.

Q4: What is the power supply requirement?

A: We can customize the motor voltage (e.g., 220V/380V/415V, 50Hz/60Hz, 3-Phase) to match your local electrical standards.
