Advantages

Specail aluminum alloy mould block adopt efficent radiating structure, ensuring high theral conductivity, rigidity and wear resistance

An integral vacuum casting technique is applied on mould blocks in which the internal vacuum channel is casting in one time with an accurate demesion and dense materials, effecitive avoiding the weakness of stength caused by the second mechanical process

Specail spray sand treatment on the mould block surface improvoes the srtength and rigidity and contributes to the corrugation moulding.
