1) Hot extrusion is an early extrusion technology used in several extrusion processes. It is used in hot forging temperature with the help of good plastic characteristics of materials to carry out various extrusion forming of metals. It is widely used in the production of aluminum, copper and other non-ferrous metal pipes and profiles, which belongs to the scope of metallurgical industry. 2) Hot extrusion characteristics: 1. The extrusion process is relatively simple, one extrusion forming, fewer processing processes (only six kinds of equipment to complete the finished work of the profile), the production efficiency is relatively stable. 2. Save raw materials and machining time. 3. The extruded products have good quality and high precision. 4. Extrusion pressure is small, can be squeezed high strength, large size products. Aluminum extrusion machine as the name suggests is mainly extrusion aluminum machine, new research and development of the frame type extrusion structure in 2018, compared with the previous old extrusion rate to increase 3-5 times, profile output 12 hours can be extruded 12 tons, the virtue comprehensive advantages of the above, perfect after-sales, is also consistent with more than 500 users praise, always in accordance with the contract delivery, More than 90 days production cycle, free installation and debugging, lifetime maintenance. 2, aluminum cold extrusion process characteristics: 1) cold extrusion is no chip, less chip parts processing technology, refers to in the cold state of the metal blank into the die cavity, under the action of strong pressure and a certain speed, forced metal extrusion from the cavity, so as to obtain the required shape, size and extrusion parts with certain mechanical properties. 2) Cold extrusion features: 1. Save raw materials. 2. Improve labor productivity. 3. The workpiece can obtain the ideal surface roughness and dimensional accuracy. 4. Improve the mechanical properties of parts. 5. Can process the shape of complex, reduce the cost of parts.
