Welcome to MMDS – an online source for engineering properties data for various mold and core binders & materials and processes for the design and simulation engineers developing new or redesigning an existing metal cast component. Use Alloy/Mold Materials/Process search option to find the properties of mold and core material for the choice of your alloy and Molding / Core making process. Use Desired Property Search option if you know the desired tensile strength, permeability and/or transverse / flexural strength values for your mold/core material and finally use the last menu option – Available Material/Processes; where we have a list of all the available mold/core materials in conjunction with alloy and processes currently in MMDS. Additional information on how to use, click on Help, About, Tutorial under General Menu on your left.
