Transfer molding (BrE: transfer moulding) is a manufacturing process in which casting material is forced into a mold. Transfer molding is different from compression molding in that the mold is enclosed [ 1 ] rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact.

A horizontal hydraulic press for hot aluminum extrusion (loose dies and scrap visible in foreground) There are many different variations of extrusion equipment. They vary by four major characteristics: [1] Movement of the extrusion with relation to the ram. If the die is held stationary and the ram moves towards it then it is called "direct ...
Its three variants are thixocasting, rheocasting, and thixomolding. SIMA refers to a specialized process to prepare aluminum alloys for thixocasting using hot and cold working. [clarification needed] SSM is done at a temperature that puts the metal between its liquidus and solidus temperature, ideally 30 to 65% solid.
Extruded bricks – For extruded bricks the clay is mixed with 10–15% water (stiff extrusion) or 20–25% water (soft extrusion) in a pugmill. This mixture is forced through a die to create a long cable of material of the desired width and depth.
Extrusion is a manufacturing process used to make pipes, hoses, drinking straws, curtain tracks, rods, and fibre. [1] The granules melt into a liquid which is forced through a die, forming a long 'tube like' shape. The shape of the die determines the shape of the tube. The extrusion is then cooled and forms a solid shape.
Mold cavity: The combined open area of the molding material and core, where the metal is poured to produce the casting. Riser: An extra void in the mold that fills with molten material to compensate for shrinkage during solidification. Gating system: The network of connected channels that deliver the molten material to the mold cavities.
