2、NUM ASSOCIATION The Aluminum Association, based in Washington, DC with offices in Detroit, MI, represents primary producers of aluminum, recyclers, and producers of semi-fabricated products. Member companies operate almost 200 plants in 37 states. NOTICE Disclaimer The use of any information contain

While the Association believes that its compilation procedures are reliable, it does not warrant, either exp

7、rmanent mold and sand castings are widely used in all types of applications due to aluminums exceptional characteristics and the great design flexibility inherent in these two casting processes. Historically, foundries each used their own individual standards covering the various aspects of permanen
8、t mold and sand castings. As new techniques and molding materials became available, they also contributed to further variations. The variations in that information, along with the lack of data in many areas, indicated the need for reliable and realistic criteria to which castings could be consistent
9、ly produced. These criteria would provide all persons involved in the procurement of castings with an instrument by which they could expect foundries to base proposals and produce castings to a specific quality level. Therefore, The Aluminum Association, as a service to the customers of the industry
10、, prepared this guide for designers, engineers, buyers and production personnel as to the most economical use of the permanent mold and sand casting processes. This guide has two series of product standards: E Series, Engineering Standards and M Series, Metallurgical Standards and Data. Dimensions,
11、tolerances and other quantities expressed in both U.S. customary and Metric units in these standards are not necessarily identical due to rounding practices used by the committee. Where standards bear dates other than 2000 (e.g.: AA-CS-M9-74), they have nonetheless been reviewed and reaffirmed by th
12、e committee in 2000. These Product Standards are not intended to be limiting in any way but rather they are expected to provide a measure of optimum conditions for the most economical use of the processes included and to provide consistency in terminology and definition, thereby resulting in a bette
13、r understanding between supplier and user. The use of these standards by any member or nonmember of The Aluminum Association is voluntary and issuance or existence of these standards does not in any respect prevent or restrict any member or nonmember from manufacturing or supplying products not in c
14、onformance with these standards. As all published material is subject to change as new experience is gained, it is suggested that the data contained herein be verified with The Aluminum Association if there is any doubt as to their current validity.

19、 NOTE: The values shown herein represent normal production practice at the most economic level. Greater accuracy involving extra close work o r care in production should be specified only when and Mere necessary since additional costs may be inuohred. Conversely, more iiberal vaiues should be in- di
20、cated, when acceptable, as these tend to keep costs to a minimum. Any variations in these values shall not be binding on the foundry unless accepted in miting. The use of sand and/or metal cores broaden the design flexibility of sand and permanent mold castings by allowing a hole or undercut to be p
21、roduced in a surface of a casting perpendicular to the parting plane. Since these cores are separate from the sand or metal mold there must be a clearance allowance for pla- ment or movement. Such allowances create an added variation in dimensions of a surface produced by the core to a surface produ
22、ced by the mold. The amount of this additional tolerance is governed by the projected area of the core.

Dimensions wholly within the area of a single core need not have this tolerance added; linear tolerance, only, would apply. t 6 Copyright The Aluminum Association Inc.
