Laempe Reich is the leading foundry core machine supplier in North America providing sand core equipment and core technology for the metal casting industry
Hot Box or Warm Box core machines are designed for use with an inorganic resin system These machines follow some basic design principles found in the cold box machines but with a main difference being in the tooling heating system and certain machine cooling processes

Sand Core Making Cores are produced by blowing ramming or in heated processes investing sand into a core box The finished cores which can be solid or hollow are inserted into the mold to provide the internal cavities of the casting before the mold halves are joined
CORES AND COREMAKING SESSION 1 ONE BINDER SYSTEM The process requires only simple modifications of conventional coldbox coremaking and mouldmaking equipment Their extended bench life helps reduce costs associated with downtime machine cleanup and wasted sand
This sand core making article illustrates how simulation helps optimize the design of core boxes and establishes robust process conditions Through validated research and experiments the sand core model in FLOW3D Cast lets engineers innovate and design
Equipment Manufacturers International Inc EMI is a global leader in the design and manufacturing of sand core machinery auxiliary equipment and stateoftheart complete core room systems EMI gained expertise in core room solutions while originally supplying cores to the automotive industry
On average our Isocure machine runs fifty percent higher productivity over a comparable Isoset machine which improves leadtimes for these cores Not only does this machine reduce cost with faster cycle times Isocure sand is about thirty percent less expensive than Isoset sand and we are able to do the core box rigging inhouse
Silica sand represents the bulk of the sand grades used for the cold box process although no statistical data on the exact distribution of the sand matrices exist European silica sands nearly exclusively date from the Tertiary and Cretaceous periods and represent the products of weathering of quartzrich prehistoric rocks in sedimentary deposits
