Aluplast – ZTG, an Altest company, has recently expanded its production capacity with a second Nitrex nitriding system. The Bulgarian aluminum extruder experienced a big manufacturing boost after installing new extrusion presses to meet customer demand for its extrusion profiles used in residential and commercial construction. The first nitriding furnace, a compact N-EXT-412, had been in operation since 2011. As for the new second furnace, a model N-EXT-612, it is the same as the first one but bigger, capable of processing a load of extrusion dies weighing up to 1300 lb. (600 kg). A good relationship, trust in Nitrex’s technology to deliver superior and consistent nitrided die results, the dependability of our technical services, and a short delivery delay all helped Aluplast decide to purchase the N-EXT-612. The nitriding system includes remote access software and complies with the AMS 2759/10 standard for controlled nitriding as well as the AMS 2750 standard in terms of pyrometry and temperature distribution. Moreover, the system is equipped with an ammonia sensor for leak detection and an ammonia filter to purify the supply gas used in the process by eliminating any oil content, thereby prolonging the system’s service life.
