UNItube Blow Tube System

 

 

The UNItube System™ solves many problems commonly encountered in production core making. Misalignment of the core machine at the squeeze-blow position can often cause severe damage to an unyielding metal tube or the core box. The UNItube System™ absorbs greater misalignment stress due to its unique high-impact plastic design.

Since metal blow tubes are manufactured in fixed increments of length and diameter, a core shop must stock many sizes of tubes and tips for service replacement. But by simply trimming the UNItube’s tip with a sharp knife, you can custom-design the tube to suit whatever requirements you have.

The UNItube System™ seats into a single angle cone, steep enough to minimize sand retention. The blow plate requires only on 30-2mm tapped hole – a substantial savings over conventional metal blow plate preparation. The 30-2mm tap and the special cutter for forming the socket are available from Humtown.
