TOOLS FOR HOT EXTRUSION OF ALUMINIUM
The process of hot extrusion of aluminium alloys results in the production of pipes, bars and profiles of various shapes and sizes. The term hot extrusion itself is used to describe a process in which aluminium alloy billet is heated up to a certain temperature and then placed into the recipient. The latter is then closed on one side with a die, mandrel or supporting components defining the product's shape, and on the other with the press head, which is being pressed by the extrusion press ram. During the hot extrusion the aluminium alloy "flows" through the die due to high pressure. As a result of transformation in the hot state the desired profiles with full or hollow crossections are produced.
The hot extruded products or semiproducts are used in the various fields, such as
Heat treatment of steels is a process in which properties of the material are altered when the temperature is changed. Time plays an important role in this process, thus the changes that occur are presented in T-t (temperature-time) diagram.
Company Kaldera d.o.o. offers the following heat treatment and machining services:
Company Kaldera d.o.o. also offers machining services, namely cutting, drilling, turning, milling, grinding, wire erosion, sinking erosion and manual treatment.
Two modern CNC machining centers Maho DMU 60T and Maho DMU 60monoBLOCK are used for the purposes of CNC milling. These two are indispensable in relation to the production of individual parts for all types of toolmaking.
The state-of-the-art CNC lathe ensures the efficiency and productivity in order to satisfy different customer's needs.
The company also provides services of sinking and wire erosion on state-of-the-art machines, as well as toolmaking processes (e.g. drilling, grinding, polishing, etc.).
