Spreading aluminium extrusion die features and design points

Spreading aluminium extrusion diecould be used for manufacturing of wide profile sections in the extrusion industry.With spreading feeder plate,the dies force the metal flow to sideways and spread so as to extrude sections with wider dimensions than the initial billet or the maximum container diameter.

Spreading aluminum extrusion die features:

1. The geometry of the deforming zone in the die was formulated and metal flow even,spread feeder plate plays an important role to make round extrusion container into flate one,its spread deforming width rate can reach 15%-25%,

2.Also spread feeder plate increase dead extrusion zone,and friction will increase about 20%,this will influence flow evenness.

Advantages of spreading extrusion die technology:

1.Enhance press capability;

2.Spreading minimalizes the die thickness to reduce back end scrap;

3.Cost reduction.

Spreading extrusion die design factors:

1.spread amount,it depends on deforming and die mantrel strength; 2.spread rate,15%~35% is suitable range; 3.spread angle,less than 30°; 4.spread hole shape and size; 5.spread extrusion die diameter; 6.spread extrusion die thickness.
