Two kinds of extrusion process characteristics of aluminum extrusion machineA, Hot extrusion process characteristics:1) Hot extrusion is an early extrusion forming technology used in several extrusion processes. It is a kind of extrusion forming of metals under hot forging temperature with the help
Since the aluminum profile was born, it has experienced a vigorous development, and every year with a speed of nearly 20 ~ 25% in the development. With the progress of The Times and the development of science and technology, improving production efficiency has become the greatest competitiveness of
Production Guide for Heat Sink Aluminum Profile As we all know, aluminum alloy has good heat dissipation performance, in our daily life, aluminum alloy heat sink is widely used, and the heat sink market is also very large.As a producer, heat sink profile is a kind of high difficulty and high cost o
Introduction to Heat TreatmentThe aluminum extrusion dies use hot steel as the base material. It needs to go through the heat treatment procedure to improve the hardness and toughness to meet the extrusion conditions of high temperature and high pressure.Generally, during heat treatment, in order to
Some problems about hollow dies and die corrections 1.Twisting and side bending of square and round tube diesThe causes of torsion and side bending defects of aluminum extrusion profiles are mainly caused by uneven flow velocity caused by uneven metal supply.The picture below is a schematic diagram
Die correction is an important factor in aluminum extrusion processing, there is no 100% perfect die, first pass rate only 60% for the average. Only through die correction, product quality and processing efficiency can be improved continuously.Last time we discussed some die corrections about hollow
