Abstract
The subject invention relates to a new method for manufacturing extrusion die tools that eliminates the step of hardening the steel after cutting the steel to form the desired extrusion die tool design. The new method involves the steps of cutting and finishing steel to form the desired extrusion die tool design, coating the die tool, or parts thereof, and hardening the coated die tool. The new method for manufacturing extrusion die tools reduces the time and the cost involved in their manufacture.
Claims24
A method for manufacturing an extrusion die tool, the method comprising the steps of:
- (a) cutting and finishing steel to form a finished state of an at least one-piece extrusion die tool;
- (b) coating at least one portion of the at least one-piece extrusion die tool with a wear resistant coating at a high temperature;
- and
- (c) hardening the at least one-piece extrusion die tool and the at least one coated portion.
A method of creating a mandrel insert for an extrusion die tool, the method comprising the steps of:
- (a) cutting and finishing annealed steel to form a finished state of the mandrel insert;
- (b) coating the mandrel insert with a wear resistant coating at a high temperature;
- and
- (c) hardening the coated mandrel insert.
