Abstract
A method for producing a breech slide of a firearm in a metal injection molding process. The process includes the following steps: a green body is injected in an injection mold. The green body is cooled. The binder is removed from the green body to form a brown body. Then the brown body is sintered.
Claims7
A method of producing a breech slide of a firearm in a metal injection molding process, which comprises the following steps:
- injecting a green body in an injection mold;
- cooling the green body in a continuous furnace;
- removing binder from the green body to form a brown body;
- and
- sintering the brown body.
A method of producing a breech slide of a firearm in a metal injection molding process, which comprises the following steps:
- injecting a green body in an injection mold;
- cooling the green body in an oil bath or in contact with heated parts;
- removing binder from the green body to form a brown body;
- and
- sintering the brown body.
A method of producing a breech slide of a firearm in a metal injection molding process, which comprises the following steps:
- injecting a green body in an injection mold and molding the green body such that, on removal from the injection mold, the green body has a sprue and at least one runner;
- cooling the green body;
- removing binder from the green body to form a brown body;
- and
- sintering the brown body.
A method of producing a breech slide of a firearm in a metal injection molding process, which comprises the following steps:
- injecting a green body in an injection mold for molding a breech slide with a sprue and/or at least one runner;
- cooling the green body;
- removing binder from the green body to form a brown body;
- sintering the brown body;
- and
- retaining the sprue and/or the at least one runner on the breech slide until after the step of sintering the brown body.
A method of producing a breech slide of a firearm in a metal injection molding process, which comprises the following steps:
- injecting a green body in an injection mold and molding the green body with a sprue;
- cooling the green body;
- removing binder from the green body to form a brown body;
- and
- removing the sprue and pushing the sprue into a bore in the breech slide to be produced, in order to serve as a support in the bore during a following sintering step;
- and
- subsequently sintering the brown body.
