The Test Pieces Blower is used to make standard tensile, transverse (except cold box) and hot distortion test pieces.

Considering that blowing is the most widely used compacting method for chemically bonded sands, the Test Pieces Blower was designed so the control of sands and binders is performed under conditions similar to those in a plant. The operation of the instrument is done via a single lever that controls the movement of the tooling and the sand blow. 

When using the appropriate core box tooling and accessories, test specimens can be prepared for:

• Tensile strength – shell sand
• Cold Tensile strength, hot and warm box
• Transverse strength/hot distortion – shell sand
• Disc transverse strength hot and warm box (special tooling is required for sample preparation – requires Disc Transverse Tooling, Model 42109C).
