METHOD FOR PRODUCING CODING SURFACES FROM A BLANK

摘要

A method for coding components of a locking system which are used to code a key and a female lock part. The coding components may be formed integrally with the key and female lock part or be provided as coding discs that are then affixed to non-coded bodies used for the key and female lock part. A blank of an easily machinable preliminary material is separated into two coding parts with a separation cut that simultaneously creates a coding surface on each coding part. These coding parts serve as the model to mold the coding components in a lost-wax process. Each coding part is encased in a material that forms a mold shell. The coding part is then melted or gasified and escapes from the mold shell, which now has a mold cavity that is then cast with the final material to be used for the coding components.
