Coremaking Machines
• Equipment Merchants International Inc., Cleveland, now offers Primafond coldbox core machines that are completely integrated with enclosed machine and gas generator.
Sand Systems
• Te CoolTech Sand Cooling Water Addi- tion System’s software determines the water required to automatically maintain desired sand temperatures without overwetting the return sand.
Ceramic Mold Media
• A closed-loop molding system can be de- signed with Carbo Accucast ceramic media from Carbo Ceramics, New Iberia, La. Te amount of binders required reduces with recycled use, according to the company.
• Te chemically inert, pH neutral media features high permeability, thermal stability and similar resin requirements vs. sand.
Nobake Resin
• Other factors impacting the bottom line include better reclaimed sand usage and faster tensile strength devel- opment for improved productivity.
• BioSet T from HA International LLC, Westmont, Ill., is formulated with a solvent package that includes methyl ester veg- etable oils such as canola. Tis reportedly improves working conditions due to lower emissions as well as reduced resin levels.
PUNB Binder
• Pepset Patriot currently is offered solely to large ductile iron casting manufacturing facilities in North America.
• The Pepset Patriot phenolic urethane nobake (PUNB) binder was designed for large scale manu- facturing from ASK Chemicals, Dublin, Ohio, as an alternative to furan-based binder systems. PUNB binders traditionally are used for smaller scale mold and coremaking due to their relative short working life, but recent research has found a way to create PUNB binder technology with longer mixed sand working life.
Visitors stop by the Simpson Technologies booth, which displayed various equipment includ- ing the Model 2-Cell Pro-Claim sand reclaimer.
MELTING Industrial Gas Solutions
• Argon, helium, hydrogen, nitrogen and oxygen are avail- able in a variety of delivery options for various furnace types and metals from Air Products, Lehigh Valley, Pa.
• Te company’s application engineers evaluate operations using furnace modeling, data collection and process moni- toring to help identify solutions to problems and recom- mend process improvements.
Induction Melting Equipment
• Ajax TOCCO Magnethermic Corp., Warren, Ohio, offers a 90-ton vertical nose-tilt channel furnace for iron. Primary melting is done with four 30-ton, 2,000 kW Jet- Flow furnaces for iron.
• Te company’s latest design for high power density coreless furnaces is the result of months of research into existing designs and a careful analysis of what is required in this “maximum duty” iron melting application.
May 2013 MODERN CASTING | 65
• Summit Foundry Systems Inc., Fort Wayne, Ind., provides sand, casting handling and automatic mold handling systems, as well as turnkey foundry design projects. Its automatic mold handling indexing systems can be integrated with the automatic mold- ing machines.
• Te machines handle vertical and horizontal coreboxes in metal and wood.
