Isocure vs. Shell

Supreme Cores recently completed a case study on a two pound core for iron castings being made in Shell.  We rigged the core box in-house for our L10 Laempe machine and produced the core in our Isocure department.  Below are our findings. 

–          57% reduction of sand cost from Shell to Isocure

–          57% increase in the productivity from Shell to Isocure.

–          25% increase in the productivity of finishing and packaging of the cores because they are of a better quality.

–          Better sand compaction

–          Lower scrap at the Foundry in castings lost.

–          Lower tooling costs


These same results could be achieved on other similar Shell jobs that you may be making.  Contact us if you would like a quote.

Rave Reviews for 2012

Supreme Cores proves that they are a leading supplier for all casting manufacturers.  For 2012, Supreme Cores received a 100 out of 100 Supplier Performance score from Pure Power Technologies in Waukesha, WI.  This combined with other high scores helped Supreme Cores average a score of 92 for all customers providing a report.  Supreme Cores is continually looking to improve and help their customers reach their goals.


Recently, we at Supreme Cores have added a new Tinker Omega TOM-125 sand mixer to our Airset department to accompany the existing Palmer 200.  The decision to add this machine was made to increase capacity and also help decrease the amount of scrap sand.

Over the short period of time that we have had this installed, we have seen a decrease in sand scrap by using preset recipes to control the flow of the sand.  By selecting a unique recipe the machine knows when the correct amount of sand has been dispensed and will shut off.  The mixer also runs off of an Allen Bradley PLC which has the EZ-Calibration option.  This option decreases the time needed to calibrate the system.  Cutting the calibration time will cut down on set up and give us more time to produce your cores.  Also, we now have the option of running additives on both of our mixers.

  Along with this machine, we are also going to add a conveyor system that will create a better flow.  Materials will be flowing in a more efficient manner and employees will be focused on value added work.


Quality is our Priority

Our quality lab is responsible for making sure our facility is running within the set parameters on a daily basis.  The lab is equipped to perform Loss on Ignition (LOI) , mold strength and surface hardness tests.  The results of these tests can be sent to you weekly in the form of an excel spreadsheet or a control chart.  The lab is also responsible for calibrating all of our measuring equipment.  All of these devices are on either a monthly, bi-yearly or yearly cycle.
