The die includes a first end ring gate concentric with the first ingate and defining a first end ring chamber in fluid communication with the first annular chamber, and a second end ring gate concentric with the second ingate and defining a second end ring chamber in fluid communication with the second annular chamber. The die includes runners interconnecting the first and second end ring gates. Each of the runners defines a conductor bar channel in fluid communication with the first and second end ring chambers. The die includes an overflow gate disposed between the first and second ingates, wherein the overflow gate defines an annular overflow chamber in fluid communication with the conductor.

Abstract: A process of forming a low cost, erosion, oxidation, and wear resistant one-piece composite liner or insert that can be installed into a shot chamber in a die casting machine is provided. The process utilizes a thin inner layer of refractory metal to serve as the working surfaces of a shot chamber. The thin refractory layer is bonded metallurgically to a thick low cost material to form a one-piece liner thick enough to resist thermal distortion during die casting operation. A self-healing erosive wear resistant coating is applied on the working surface of the refractory metal layer. Such a one-piece composite liner is expected to have an improved service life for die casting of corrosive metals and alloys.

Abstract: A casting insert includes a casting insert wall formed substantially of a liquid-phase-sintered refractory metal alloy, a cavity formed by the casting insert wall, and at least one cooling duct, which is different from the cavity and which is formed at least partly within the cavity and/or which is formed at least partly within the casting insert wall. The casting insert wall has a wall thickness which can be defined as a normal distance between a point of the casting insert wall which faces the cavity and a point on an outer surface of the casting insert wall. The wall thickness is, at least in sections, less than 25% of a diameter of the casting insert.

Abstract: The purpose of the present invention is to provide a mold having both good adhesion resistance and smoothness, and a production method therefor. Provided is a mold made of a composite material comprising hard phases and metal phases characterized in that the mold has a reinforced layer made of hard phases for a working surface and the working surface satisfies the arithmetic average roughness Ra≤0.1 μm and skewness Rsk≤−0.01. Also provided is a production method for a mold made of a composite material comprising hard phases and metal phases characterized in having: a shaping step for working the surface of the mold made of said composite material and adjusting to Ra≤0.1 μm; and after the shaping step, a surface layer-modifying step for etching the surface of the mold adjusted to Ra≤0.1 μm and removing the metal phases near the surface.
