Patternless ® Process

The Patternless® Process was invented and developed by Cti. It is a technique whereby moulds are directly machined out of blocks of sand. This proves to be a very cost effective way of producing one-off or small production run castings, since it does not require the manufacture of patterns and core boxes.

The benefits associated with the process include:

• reduced time to manufacture
• reduced total manufacturing costs
• castings of high integrity and dimensional accuracy
• appropriate surface finish and enhanced letter definition
• suitable for castings of all sizes and weights
• opportunities for one-off and small series production
• no pattern storage or maintenance costs

The features of Cti's Patternless® system include:

• working envelope of 3.6 x 3.6 x 1.2m;
• rough machining of a mould cavity equivalent to one tonne casting in 30 minutes;
• machining accuracy of ±0.01mm;
• uses specially developed cutters with minimal wear;
• uses block of sand (up to 10,000kg) readily made in any foundry from new or reclaimed sand.

High Performance Machining is performed at the CTi.
