Resin Coated Sand
Custom Coat Resin Coated Sand
HA International customizes each and every resin coated sand formulation so you can optimize your operation’s unique capabilities. Our Custom Coat product line is produced and manufactured to your products exact specifications.
Super F®, Super FII®, FT® Resin Coated Sands
The Super Series coated sands were developed to accelerate machine cycle times. The investment rate and cure time of these products is as much as 35% faster than standard products. This results in reduced core and mold cycle times. Super Sands have also demonstrated improvement in uniformity of cure which allows reduced core and mold weights.
SHAKE-FREE®
Shake Free resin coated sands are designed for use in aluminum and brass applications where core shakeout is a critical factor. Shake Free can eliminate or reduce the need for costly operations required to remove cores from castings.
Custom Coat E-Series Resin Coated Sand
We have extended our resin coated sand product line to include Custom Coat E-Series, an environmentally compliant line of formulas that reduces ammonia and formaldehyde emissions by 30% and 60% from conventional formulas.
Sigma Sands are the sands of choice for environmentally conscious foundries. Lower phenol, lower nitrogen, reduced odor and improved casting quality are the most significant attributes of these products. Sigma Sand and Sigma Sand LP represent the latest Shell Process Technology.
Troubleshooting the Shell Process
Operating problems can occasionally crop up, even in the most carefully supervised shell process operations. When they do, quick corrective action can make the difference between a minor inconvenience and a serious dollar expense to the foundry. Our trouble shooting guide draws on the experience of HAI’s field and laboratory personnel to summarize some of the more common shell process operating problems with suggested solutions that have been successfully used in other foundries.
