SM 4H PRO FAST

When it comes to welding PVC profiles and hybrid materials, the SM 4H PRO FAST by Someco, a brand of the Voilàp Group, stands out as one of the most advanced solutions for the production of high-quality windows and doors. This numerically controlled horizontal welding machine is designed for companies that refuse to compromise between productivity, precision, and aesthetic finish.

Four corners, one perfect weld

SM 4H PRO FAST enables frame production through the simultaneous welding of four 90° corners, optimizing cycle times while ensuring consistent quality on every piece. The bidirectional symmetrical welding technology improves the polymerization of the molten material, eliminating transverse micro-slippage and ensuring a superior finish. The welding machine also supports an asymmetrical mode, allowing the completion of structures with transoms and guaranteeing maximum production versatility.

Seamless Technology: beadless welding for a superior finish

The core of the PRO FAST version is the Seamless technology, which enables beadless welds on the visible surfaces of the window frame, simplifying the production process and significantly improving the aesthetic quality of the final product. In its PRO FAST version, the SM 4H offers a range of tangible benefits:

• designed to optimize welding with Seamless technology, it integrates knives within the welding units to control finishing quality;
• reduces testing costs and processing times thanks to the use of more functional counter-shapes and integrated knives;
• complete synergy with the Someco CM 4H milling machine, enabling unlimited productivity managed by a single operator.

Ergonomics and ease of operation

SM 4H PRO FAST is designed to make the operator’s work simple, safe, and intuitive. Status indicator lights on the welding heads display the operating status at every stage, while the automatic movement of the heads facilitates workpiece positioning. All cycle parameters are fully programmable, minimizing the possibility of errors.
