Dowel– A pin of various types used in the parting surface of parted patterns or dies to assure correct registry.
Draft– Taper on the vertical sides of a pattern or corebox that permits the core or sand mould to be removed without distorting or tearing of the sand.
Drag– The bottom half of a horizontally parted mould.
Ejector pins– Movable pins in pattern dies that help remove patterns from the die.
Facing sand– The sand used to surround the pattern that produces the surface in contact with the molten metal.
Feeder– Sometimes referred to as a “riser,” it is part of the gating system that forms the reservoir of molten metal necessary to compensate for losses due to shrinkage as the metal solidifies.
Finish allowance– The amount of stock left on the surface of a casting for machining.
Finish mark– A symbol (f, fl, f2, etc.) appearing on the line of a drawing that represents the edge of the surface of the casting to be machined or otherwise finished.

Mould– Normally consists of a top and bottom form, made of sand, metal or any other investment material. It contains the cavity into which molten metal is poured to produce a casting of definite shape.
Mould cavity– The impression in a mould produced by removal of the pattern. It is filled with molten metal to form the casting.
Mould coating– A liquid suspension of a refractory material applied to cores and dried (intended to improve surface of casting).
Nobake process– Moulds/cores produced with a resin-bonded air-setting sand. Also known as the airset process because moulds are left to harden under normal atmospheric conditions.
Parting line– The line showing the separation of the two halves of the mould.
Pattern– The wood, metal, foam or plastic shape used to form the cavity in the sand. A pattern may consist of one or many impressions and would normally be mounted on a board or plate complete with a runner system.
Pattern draft– The taper allowed on the vertical faces of a pattern to permit easy withdrawal of the pattern from the mould or die.
Pattern layout- Full-sized drawing of a pattern showing its arrangement and structural features.
Patternmaker’s shrinkage– The shrinkage allowance made on all patterns to compensate for the change in dimensions as the solidified casting cools in the mould from freezing temperature of the metal to room temperature. The pattern is made larger by the amount of shrinkage characteristic of the particular metal in the casting and the amount of resulting contraction to be encountered.
Permeability– The property of a mould material to allow passage of mould/core gases during the pouring of molten metal.
Physical properties– Properties of matter such as density, electrical and thermal conductivity, expansion and specific heat. This term should not be used interchangeably with “mechanical properties”.

The system normally consists of a vertical section (downgate or sprue) to the point where it joins the mould cavity (gate) and leads from the mould cavity through vertical channels (risers or feeders).
Sand inclusions- Cavities or surface imperfections on a casting caused by sand washing into the mould cavity.
Scrap– (a) Any scrap metal melted (usually with suitable additions of pig iron or ingots) to produce castings; (b) reject castings.
Shakeout The process of separating the solidified casting from the mould material.
Shrinkage– Contraction of metal in the mould during solidification. The term also is used to describe the casting defect, such as shrinkage cavity, which results from poor design, insufficient metal feed or inadequate feeding.
Slag– A fused nonmetallic material that protects molten metal from the air and extracts certain impurities from the melt.
Slag inclusions- Casting surface imperfections similar to sand inclusions but containing impurities from the charge materials, silica and clay eroded from the refractory lining, and ash from the fuel during the melting process. May also originate from metal-refractory reactions occurring in the ladle during pouring of the casting.
Slurry– A flowable mixture of refractory particles suspended in a liquid.
Sodium silicate/CO2 process– Moulding sand is mixed with sodium silicate and the mould is gassed with CO2 gas to produce a hard mould or core.
