A decade ago, we introduced the first of the 500-series: a machine that welds and cuts PVC-coated fiberglass in fully-automatic, continuous cycles, and creates retractable insect screens of the highest quality.
We designed the SM-500-ZA to produce custom-sized insect screens with a maximum width of 2,8 m and lengths up to 3,0 m. When we received a request to develop an even bigger machine to make insect screens in 6-meter bars, our R&D-team designed the SM-520-ZA: a powerful machine that produces 6-meter wide retractable insect screens that are perfectly cut, with welded-on coextruded profile to the top and pocket-with-rope to the bottom. The product is then rewound on the aluminum bar and inserted in the box with the lower hand-grip attached, all within a record-breaking 2 minutes and 48 seconds.

SM-500-ZA
Automatic Welding Machines for Custom-Sized Retractable Insect Screens
Machines of the 500-series are the ultimate breakthrough in the automated production of custom-sized insect screens. The first – and only – line of machines that manufacture quality screens ready for installation in a continuous cycle.
The SM-500-ZA has a simple yet solid structure. Top-of-the-bill electronic and pneumatic components and precision welding tools make this machine the best manufacturing solution for retractable insect screens currently available on the market.

SM-520-ZA
Automatic Welding Machines for Custom-Sized Retractable Insect Screens and 6-meters Profiles
First introduced in 2005, machines of the 520-series revolutionized the insect screen creation industry by drastically reducing the production time needed to make a 6-meter-wide screen, required human resources, and discarded materials.
With a wide selection of tools and accessories combined with a sturdy modular structure, this machine is, by far, our most efficient manufacturing solution for quality 6-meter profiles and custom-sized retractable insect screens solutions available on the market today.
