"Comments from the President" •


\:... \:... • From scientific moon shots to


entertainment processes at Disney- land, investment castings are being


used for a multitude of applications. Not only in this country, but world wide, investment castings are playing an ever increasing role in our daily lives.


This unique method of producing parts reaches far back into the history of metal- working. But its great potential for easily producing highly complex parts lay dormant until brought to life by the urgent demands of our last great war. Now, 20 years later, there has yet to be found a design limitation for the process. Almost anything can be investment cast. The process is literally a designer's dream. Intricate valves, lofted con- tour blades, tiny parts with precision details ... What do you need? Chances are it can be investment cast.


Cost savings in many applications are being reported. The versatility of the process has shown savings of up to 95 % of manufactur- ing costs by other methods. One investment casting can replace expensive machining, dip brazing, bending, and other fabrication meth- ods, with the added plus benefits of greater strength, versatility, lighter weight and appearance thrown in for good measure.


There appears to be no letup in sight for the uses of investment castings. The process's growth rate promises to continue to soar as engineer after engineer, in industry after industry, discovers how investment


castings can open the door to de- signs never before thought possible.

NEW


Investment Casting Handbool< To Be


Released In


1967 ...


President L. R. Schwedes, Lawrence Laboratory, reports that the Investment Casting Institute plans to release its new Technical Handbook in 1967.


The Handbook is currently in the hands of a special Book Committee for final editing.


The new Handbook will contain over 100 illustrations of applications for investment castings. Applications will be shown for strength; corrosion resistance; abrasion resistance; heat resistance; weight; electrical characteristics; pressure tightness; and heat dissipation.


Applications will also show: complexity; cast assembly; ideas for design improve- ment; miniature parts; large parts; and thin walled investment castings.


The Handbook will contain comprehensive information on dimensional tolerances for investment castings, and ideas for good design of an investment cast part.


The Handbook will also contain compre- hensive information on alloy selection.


L. R. Schwedes


The Handbook is scheduled for completion early in 1967. If you wish to be put on a mailing list to receive information on the availability of the new Investment Casting Handbook, you are invited to write to the Investment Casting Institute.
