  • Pattern (casting) Wikipedia

    In casting, a pattern is a replica of the object to be cast, used to prepare the cavity into which molten material will be poured during the casting process.. Patterns used in sand casting may be made of wood, metal, plastics or other materials. Patterns are made to exacting standards of construction, so that they can last for a reasonable length of time, according to the quality grade of the

  • Foundry Pattern Making: Life of a Casting Reliance Foundry

    A pattern that’s been stored outside of the foundry may not have been taken care of properly and so might never make a solid casting again. Historically, destroying patterns was a risky process, since the pattern might be the most faithful capture of a design. The issue of pattern storage has therefore been a balance of concerns. Size and

  • Foundry Wikipedia

    In the casting process, a pattern is made in the shape of the desired part. Simple designs can be made in a single piece or solid pattern. More complex designs are made in two parts, called split patterns. A split pattern has a top or upper section, called a cope, and a bottom or lower section called a drag.

    The pattern material is chosen based on the casting volume and process used. Wood and metal patterns are usually used with sand casting, while wax is rarely used for anything but investment casting. Patterns vary in complexity, depending on the size, shape, and number of resulting castings required. There are many types of patterns in use in

    All aspects of a pattern must have a negative draft angle with no undercuts so that the pattern will pull from the sand. The style of pattern is determined by the quantity of parts required for casting. Split patterns are excellent for individual castings, while matchplated patterns are more efficient for larger runs and delicate patterns.

    Split pattern A split pattern models the part as two separate pieces that meet along the parting line of the mold. Using two separate pieces allows the mold cavities in the cope and drag to be made separately and the parting line is already determined. Split patterns are typically used for parts that are geometrically complex and are produced

    2017-04-19· Match plate pattern is a split pattern in which cope and drag section mounted on opposite sides of a plate. The plate is known as match plate. These will make easy to cast any shape with high production rate. Mostly runner, gates etc. are also mounted on same plate which will easy to mould making work. These patterns are used for mass production.
