for Fitting Manufacture

The HWT 400-C is a numerically controlled plastic welding machine for workshop applications developed in compliance with the so-called machinery directive 2006/42/EC as amended, that allows making segments, tees, Y pieces and crosspieces. The machine is designed for the jointing of segmented bends from O.D. 90 to 400 mm and of tees, Y pieces, and crosses from O.D. 90 to 315 mm(1).

The machine is set on a welded, heavy-duty, no-warp support frame and the bearings on which move both the horizontally traveling carriages and the heating element and facing tool assembly, are designed as precision-engineered and heavy load-bearing trapeze-shaped guides with precision-matched runner blocks. As well the insertion and retraction the heating element and the facing tool as the entire welding process are fully automated and, therefore, ensure utmost accuracy, ergonomic working, and tremendously short change-over delays. To improve the geometry of fittings and the quality of the joint, this next-generation representative of workshop technology features not only two horizontally moving and adjustable carriage consoles, but also an additional supporting cylinder (optional) for welding sizes 355 mm or larger.



The heating element temperature and the force are controlled in the course of the welding process in accordance with the applicable national standards (DVS, UNI, WIS, etc.). It goes without saying that all parameters that are critical for a high-quality and reproducible welded joint are monitored throughout the process and saved to the memory of the system, which can hold up to 10.000 reports. When the machine ships, a high-resolution color touch screen of the latest generation is included as a standard feature. This panel enables entering and viewing both all required pipe or fitting parameters and the needed traceability data.

It is a premiere that the machine features user access control by RFID technology.



Of course, the tried and tested input devices, scanning pen and handheld scanner, are also available.  Furthermore, all CNC machines are equipped with a USB interface to enable downloading the welding reports in the PDF format to a USB stick or sending them to the management database in the HÜRNER DataWork format. It is also possible to label a joint immediately for its quality by printing on plastic foil an indelible label tag with the available tag printer that will identify the fitting.
