A method for producing a forming tool having a forming punch and a mating die corresponding to the forming tool for forming a substrate is provided, which includes the steps of preparing at least the forming punch of the forming tool from a light metal and forming a protective coating on at least one region on a surface of at least the forming punch of the forming tool. The protective coating is applied to a region that is configured to contact the substrate, and in one form, the light metal is aluminum or an aluminum alloy. A forming tool having a forming part and a mating die is also provided, in which at least the forming tool is made from a light metal and includes the protective coating.

A blow mold for PET bottles has the inner surface which contacts the hot PET during the blowing operation, coated with a layer of ceramic material having a nanometric thickness, of which at least one thickness layer is AI.sub.2O.sub.3 and/or TiO2 deposited by ALD technique. Due to this technique, the PET preforms are subject to less friction during the contact with the interior of the mold.

A method for forming a die is provided. The method includes heating a die structure such that a surface thereof is at least 450° C.; and machining, by a machining system, a predetermined surface profile on the surface of the die structure while the temperature of the surface is the at least 450° C. to form the die.

To provide a method for producing a tire vulcanizing mold capable of obtaining a tire vulcanizing mold having excellent durability and high precision at low cost and to provide such a tire vulcanizing mold, the method includes producing a tire vulcanizing mold by assembling a pattern molding segment, produced by rapid prototyping, on a metal base segment, the method further includes a step of producing the pattern molding segment from a metal based on a shape of a surface layer part including a pattern shaping surface in a basic model of the tire vulcanizing mold.

A tool for forming a shaped product has a support body that is fabricated from a first material, such as for instance cast iron. The first material defines a first portion of a forming surface of the tool and has a feature supported thereon. The feature has a layer of a second material that is supported on the first material of the support body, a layer of a third material that is supported on the layer of the second material and a layer of a fourth material that is supported on the layer of the third material. The layer of the fourth material, such as for instance a tool steel alloy, defines a second portion of the forming surface of the tool. During use the first portion of the forming surface and the second portion of the forming surface cooperate to form a desired shape of the shaped product.

A system for forming a metal strip into a die having a predetermined shape through a series of forming operations is described herein. The system includes a base configured to support the metal strip as the metal strip undergoes the series of forming operations; a feeding device configured to advance the metal strip between each forming operation of the series of forming operations and grip the metal strip during each forming operation; a bending device configured to bend a portion of the metal strip extending from the feeding device as one of the series of forming operations; a forming head configured to house a pair of forming tools and provide features to the portion of the metal strip extending from the feeding device as one of the series of forming operations using the one or more forming tools; a robotic arm configured to selectively provide the one or more forming tools to the forming head; and a computing unit in communication with the robotic arm and configured to transmit a control signal to cause the robotic arm to retrieve the pair of forming tools and provide the pair of forming tools to the forming head.

The die forming process includes first passing a circular coarse thread cutter over the forming surface of the die at an angle away from parallel to a side edge matching a pitch for coarse threads to be formed by the die. In a first cutting step, the coarse thread cutter forms upper portions of crests in the forming surface of the die. In a further step, a fine thread cutter is then utilized to cut portions of the root of the dual threaded die, leaving a bridge within the root. The fine thread cutter is angled relative to the crests formed in the first step. The fine thread cutter cuts at a variable depth as the fine thread cutter advances along the root between the crests to form two flanks on sides of the bridge within the root.

A method of manufacturing a honeycomb extrusion die. The die includes a feed hole plate and a pin assembly comprising pins extending feed hole plate. One or more of the pins includes a head including an alignment surface, flow surfaces, a contact surface, and a taper located between the alignment surface and the contact surface. The pins are adhered to the output surface of the feed hole plate at their respective contact surfaces. A tail of each pin is connected to the head and extends away from the feed hole plate. The alignment surfaces of adjacent pins contact each other, such that the tails of adjacent pins are spaced apart to at least partially define discharge slots. The flow surfaces of adjacent pins are spaced apart to at least partially define channels to enable flow from the feed holes to exit the honeycomb extrusion die through the discharge slots.
