Plaster and other chemical curing materials, such as concrete and plastic resin, may be cast using single-use waste molds as noted above, multiple-use 'piece' molds, or molds made of small rigid pieces or of flexible material such as latex rubber (which is in turn supported by an exterior mold). When casting plaster or concrete, the material ...
For the production of gray iron, ductile iron and steel castings, sand casting remains the most widely used process. For aluminum castings, sand casting represents about 12% of the total tonnage by weight (surpassed only by die casting at 57%, and semi-permanent and permanent mold at 19%; based on 2006 shipments). The exact process and pattern ...
Cope and drag with cores in place on the drag Two sets of castings (bronze and aluminium) from the above sand mold. In foundry work, the terms cope and drag refer respectively to the top and bottom parts of a two-part casting flask, used in sand casting.

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.
The fast cooling rates created by using a metal mold results in a finer grain structure than sand casting. Retractable metal cores can be used to create undercuts while maintaining a quick action mold. [2] [3] There are three main disadvantages: high tooling cost, limited to low-melting-point metals, and short mold life.
The Zara Spook 9260 Series lures contained different types of hardware throughout their production. Heddon two piece hardware were the first hardware on the 1939 catalogued Zara Spook. Later lures through the 1940s and 1950s had surface hardware. Later models contained bell hardware and moulded hangers through the 1970s. In the mid-1990s, a 4 ...
