DUWELL company is the first factory to produce this high speed roller shutter, we have experience in roller shutter machines more than 20 years. We learned and imitated the machines of our Senior role models Italian DALLAN company, and developed China's first high speed rolling door equipment.
Yes, our machines are versatile and can be configured to produce both 77mm and 95mm profiles. With quick tooling changes, you can switch between profiles efficiently.
Please contact DUWELL to ask for the detailed information.
Our machines are equipped with advanced PU foam injection systems that ensure precise and consistent foam filling. The foam is injected into the profiles during the roll forming process, creating a seamless and uniform core.
Absolutely! We offer fully customizable solutions, including:
Custom profile designs
Adjustable foam density
Integration with additional features like punching, cutting, or automation systems.
120 days including production and final testing working.
We have two types of machine, high speed line and normal speed line: high speed line the speed is 25~30 meters/minute. Normal speed line speed is 10~12 meters/minute.
Our machines are designed to work with a variety of materials, including:
Galvanized steel/Aluminum/Stainless steel/Pre-painted or coated steel
The choice of material depends on the specific requirements of your roller shutter doors, such as durability, weather resistance, and aesthetics.
For 77mm and 95mm roller shutters, it mostly uses steel and aluminum with thickness 0.3~0.6mm.
The PU foam core significantly improves the energy efficiency of the shutters by reducing heat transfer. This helps in maintaining indoor temperatures, lowering heating and cooling costs, and meeting energy efficiency standards.
