Lockformer

Sure, here’s a guide to buying a Lockformer machine for duct making:

1. Voltage: Lockformer machines are commonly available in 220V and 380V for household and industrial use, respectively. The 380V machine is more powerful than the 220V machine. If the thickness of the processed galvanized plate is less than 1.0mm and you don’t have access to industrial electricity, the 220V machine is suitable. If the plate thickness is less than 1.2mm, the 380V machine is recommended.
2. Weight: Conventional Lockformer machines typically weigh between 200KG and 280KG. All models come with casters for easy handling.
3. Thickness of the locking sheet: The equipment is mainly designed for processing galvanized sheets. If you need to process galvanized sheets within 1.2mm, either the light or conventional type can be used. If the thickness of the plate is more than 1.2-1.5mm for galvanized sheets or within 1.0mm for stainless steel, a heavy-duty Lockformer machine should be chosen.
4. Shape of the lock: The common method of purchasing a Lockformer machine is based on the shape of the lock required. If you need to make C-type clips, the six-function Lockformer (FEY-12A or FEY-12A2) is necessary. If you don’t need clips but require square elbows, the four-function machine (FEB-16A4 / FEB-16A1 or FEB-16A5) should be used. If only the simplest joint angle and other functions are required, the three-function machine (FEB-16A / FEB-2A or FEB-16A2) is sufficient.
