"Builders of Foundry Machinery for Core and Mold Making"

Until recently the only way to get a return on our investment in the core shop was to switch from Shell to Isocure. Even that was minimal, considering the additional costs for tooling, disposal, green sand contamination, and environmental issues. Which is why many foundries have neglected their core shop for so long. 

Although Harrison has been on the scene since the 1950's with the introduction of the Dual Station Core Machines most comparisons and purchase justifications did not take into account the inherent productivity advantages of a Dual Station Core Machine. So for decades most thought adding or replacing a core machine simply meant an increase in  core making cost. This was true, except when a Harrison Core Machine came into the picture for consideration. Harrison Core Machines break the idea that more of the same type of equipment means more of the same results.

Productivity

• More cores per man hour.

• One operator, two workstations.

Flexibility

• Run two different core boxes simultaneously.

• Keep 2 customers on schedule with one machine.

• Longer consistent runner on one side and short runs on the other.

• High volume by running two of the same core boxes.

Utilization

• Run production on one side while the other is heating up.

• High volume can be run in half the time, with two boxes, leaving capacity for other jobs.

Reliability

• Robust simple design.

• Allen-Bradley electronics.

• Standardized pneumatics.

• 80-part Program Memory.

• Digital Thermal Controls on Shell Machines for each half of each box.

• Integrated Auxiliary Equipment Controls on the Cold Box machines.

Quick Change

• Blow-Hole Inserts, open & close blow-holes without tools.

• Universal Blow-Plate common to most jobs, seldom needs changing.

• Available Quick Change Universal Mounting Plate System, change boxes without tools or alignment.

• Recall part programs from memory.

• Available Shell Box PreHeater eliminates as much as 75% of changeover time.

Automation

• Available integrated & dedicated automatic core unloaders.

• Available core conveyors.

• Available hands free core ejection system.
