The foundry experienced reduced resin requirements and eliminated the requirement for additional mold reinforcement and the use of a mold and core wash
. Cleaning times were reduced, in one instance from 50 minutes with sand to 10 minutes with Accucast.
Simple to use, it can be added during the core wash
and pulp wash processes to retain cloudiness.
facility, incorporates a large 1900 x 900 mm core box on a vertically parted core machine, a key-core machine, a core dipping station and a core wash
A company in Milwaukee needed to dry a zircon-based core wash
on sand molds used in the manufacture of large gears.
A novel way to cut core drying costs is to use a color changing indicator in the core wash
to determine when it is dry.
Do you have a control plan that addresses all core sand properties and verifies through lab testing (loss on ignition, tensile, viscosity for core wash
Eck Industries eliminated the core wash
, or coating, from the water jacket cores, and the defects stopped appearing.
March 9--Mold and Core Wash
Practices, Location TBA.
Wescast worked with Robotec Engineering GmbH, Bad Sackingen, Germany, to integrate the core-setting automation, which begins at the core wash
After an extensive evaluation, Gienanth focused on two core handling operations--clipping into the core wash
and palletizing finished cores--for its initial automation efforts.
Q: Our foundry uses core wash
coatings for cores and molds but we are experiencing inconsistent casting finish.
The cores then are coated with a core wash
, submersed for a count of three and placed onto the conveyor to be dried in the production oven.
