Manufacturing a set of high quality aluminum extrusion dies, not only have good processing equipment and skilled extrusion mould manufacturing workers, but also a very important factor is to have good extrusion die design. For more complex extrusion die, die design is good or bad account for 85% of the mold quality, a good die extrusion design is: on the premise of meet customer requirements, to do the processing cost is low, the processing difficulty is small, short processing time, mould can in the shortest possible time to endogenous production of qualified products. To do this, not only to fully understand customer's requirement, also require mold designers of extrusion machine, extrusion die structure and processing technology and processing capacity of our factory to understand, therefore, as the extrusion mold designers, to improve the level of extrusion die design, should do the following:

1.Know the size and deviation of aluminum profile

2.Choose the correct tonnage of aluminum extrusion machine

3. Determine the shape of extrusion die

4. Determination of the size of mould die

5. Reasonable adjustment of aluminum metal flow rate

6. Check the strength of the mould

7. Reasonable working band size

8. The structure and dimension of die hole knife
