Patterns
- A pattern is the replica of the casting to be formed with some modifications. These modifications are in the form of allowances.
- Patterns are of great variety because of their different designs, constructions, and methods of use. More commonly used types are
- Solid/Single-piece pattern
- Two-piece/Split pattern
- Multi-piece pattern
- Sweep pattern
- Segmental pattern
- Skeleton pattern
- Shell pattern
- Gated pattern
- Loose piece pattern
- Match plate pattern
Match plate pattern:
- Patterns are made in two pieces, one piece mounted on one side and the other on the other side of the plate called match plate
- The plate may carry one or group of patterns mounted on match plate
- Along with the pattern, gates and runners are also attached
- Produces accurate castings at faster rates
- One advantage of using a match plate is that several patterns can be moulded in the single flask, thus saving much time and labour.
