DESCRIPTIONS

Main Features

• The mould blocks are made of special aluminum alloy for high thermal-conductivity, high rigidity and high abrasion-resistance.
• The mould blocks are molded by integral pressure casting for denser texture and higher thermal stability.
• Special treatment is applied to the inner face of mould blocks in order to not only promote the strength and rigidity of mould blocks, but also contribute to the perfect forming of corrugations.
• The vacuum channel and water cooling circuit are designed with very wide flowing cross-section in order to ensure producing stably with high quality and high efficiency.
• The cooling circuit and vacuum channel in the mould blocks are formed in one time by precision casting, which brings a higher strength and longer lifespan for the mould blocks.
   

Extrusion die head with spiral channel

• Real independent die head design. When the die head need to be changed for a different size, it can be realized easily just through some simple adjusting work. This not only makes the changing of die head easier and faster, but also ensures the precision and long lifespan of the die head. 
• The all-new die head with spiral channel can lower flow resistance of material effectively and improve the plasticizing effect through greatly shortening the channel length.

New type of stainless steel calibrating mandrel

• New type of stainless steel water cooling calibrating mandrel has outstanding abrasion resistance and excellent cooling effect. This solution can realize a perfect combination of high thermal conductivity and high stiffness with light weight.
