Abstract
Disclosed herein, amongst other things, is a gate and a related method of forming the gate, having structure and steps of providing a base of a first base material, the base having a gate area, adding a layer of a second material to the base in the gate area by an additive manufacturing process to form a metallurgical bond, wherein the second material has a characteristic that differentiates the second material from the first base material and modifying an inner surface in the gate area comprised of the second material to define the gate.
Claims41
A method of forming a gate, the method comprising:
- (a) providing a base of a first base material, said base having a gate area;
- (b) adding a layer of a second material to said base in the gate area by an additive manufacturing process to form a metallurgical bond, wherein said second material has a characteristic that differentiates the second material from the first base material;
- (c) modifying an inner surface in said gate area comprised of said second material to define the gate.
A method of forming a gate in a mold component, said method comprising:
- (a) providing a base made from a first material;
- (b) forming a gate area in said base;
- (c) providing a second material that has a characteristic that differentiates the second material from the first material;
- (d) adding a layer of the second material to said base in the gate area by an additive manufacturing process to form a metallurgical bond with an adjacent material;
- (e) forming said gate such that an inner surface of the second material defines the gate.
A gate comprising:
- (i) a base made from a first material, said base having a gate area;
- (ii) a layer formed above said first material in said gate area, said layer being made of a second material that has a characteristic that differentiates the second material from the first material;
- wherein the second material is metallurgically bonded to the first material and has an inner surface that defines the gate.
A gate comprising:
- (i) a base made from a first wear resistant material, said base having a gate area;
- (ii) a layer formed above said first wear resistant material in said gate area, said layer being made of a second wear resistant material that has a characteristic that differentiates the second wear resistant material from the first wear resistant material;
- wherein the second wear resistant material is formed above a surface of the first wear resistant material by an additive manufacturing process.
A gate comprising:
- (i) a base formed of a first material having a first hardness, said base having a gate area;
- and
- (ii) an inner layer formed on said base in the gate area, said inner layer made of a second material having a second hardness that is relatively higher than the first hardness;
- wherein the second material is metallurgically bonded to the first material and an inner surface of said inner layer defines the gate.
