The resin-to-sand ratio expresses a defined binder addition relative to a defined sand mass. It is one variable in a chemically bonded sand process. Establish

Shot blasting is one option for cleaning and preparing suitable surfaces through abrasive impact. Its value depends on the substrate, contamination, access and required finish.

Shot blasting work can expose people to projected abrasive, moving equipment, dust, noise and hazardous energy. Controls must match the equipment, abrasive, workpiece and material

Shot blasting maintenance should follow the installed equipment documentation, operating duty and observed condition. The five areas below help organize the program. They do not

Abrasive selection should align the workpiece, required surface condition and approved equipment configuration. Compare media through representative trials and complete operating costs. No abrasive is

Burrs or excess metal may remain after blasting because their geometry, attachment or location is outside the qualified cleaning capability. Begin by defining the unwanted

A core shooter uses compressed air to deliver prepared sand into a core box. The core forms internal features or other required geometry in a

Variable molding-sand properties can contribute to casting-quality problems, but the investigation should include incoming material, preparation, handling and molding. A mixer is one part of

Resin addition in chemically bonded sand should be established for the selected binder system, sand and casting requirement. Optimization means finding a qualified operating range

A hanger shot blasting machine suspends workpieces on a rated hook or fixture and moves them through an abrasive-blasting sequence. It can be evaluated when
