An assembly includes a first mold component defining a first portion of a mold cavity and a first slot. The first slot corresponds to a first portion of a retention channel. The assembly also includes a second mold component defining a second portion of the mold cavity and a second slot. The second slot corresponds to a second portion of the retention channel. The assembly also includes a connector having a cross-sectional shape corresponding to a cross-sectional shape of the retention channel. The connector has thermal expansion characteristics that are different from thermal expansion characteristics of the first and second mold components such that when the first and second mold components are in contact and the connector is inserted into the retention channel, heating the assembly causes differential thermal expansion of the connector and the mold components resulting in a clamping force between the mold components.

A casting device includes a bore formation core and a water jacket formation core. When a cavity is formed, gas existing in a space between both cores is suctioned through a flow path formed in the bore formation core under operation of a suctioning device. When the bore formation core is viewed from a side, this flow path exists above a virtual axial line that passes a center of the bore formation core and extends along a longitudinal direction of the bore formation core.

A process of forming an erosion, oxidation, and wear resistant shot chamber, either a gooseneck or a shot sleeve, is provided. The process utilizes a self-healing erosive wear resistant coating on a liner of refractory metal to serve as the working surfaces of a shot chamber. Such a shot chamber is expected to have an improved service life for die casting of corrosive metals and alloys, including hot chamber die casting of aluminum alloys. An improved hot dipping process using stirring in the motel metal bath is also disclosed.

A permanent mold has a base made of metal. The base has a plurality of first mold portions, which are mutually spaced along a longitudinal axis and which are designed to shape a bearing tunnel of a crankcase. Second mold portions are arranged on the first mold portions and consist of a mold material.

A system for casting by splitting molten materials, and more particularly, for casting molten materials received from a furnace into a plurality of unit forms of a predetermined size, including a body unit, forming a main structure of the system, providing a space where the molten materials are received from the furnace; a side packing unit, disposed at the front and rear sides of the body unit, partially covering the body unit.

The invention relates to a method for producing a helix (2), having a step of providing a permanent mold (1) with mold halves (1.1, 1.2) which can be joined together on a mold parting line (1.5). The method additionally has a step of joining together the mold halves (1.1, 1.2) of the permanent mold (1) such that the permanent mold (1) has a cavity (1.3), which defines the shape of the helix (2) or the shape of a bent-up helix (2′), when the permanent mold is joined together, wherein the specified helix (2) or the bent-up helix (2′) has a flattened profiled winding cross-section which has two opposite flat sides (2.1, 2.1′), an outer side (2.2) and an inner side (2.3) opposite the outer side (2.2), and the mold parting line (1.5) runs at least partly along the outer side (2.2) and/or the inner side (2.1) and/or edges of the profiled winding cross-section. The method additionally has a step of removing burrs (3) extending on the outer side (2.2) and/or the inner side (2.3) and/or the edges of the cast body on the mold parting line (1.5). The invention further relates to a permanent mold for carrying out the method and to a helix which has been produced using the method or using the permanent mold.
