As experienced Pattern Makers in the UK we have produced many patterns and core-boxes for the automotive industry.
Generally patterns are manufactured for engine blocks, ancillaries and parts for transmission, even wheels.
Stage 1: Make Template of Original Casting
We started by making the split pattern for the engine block using the original casting as a template:
Stage 2: Corebox
Next we created core boxes for the inside of the engine block. The inside of the corebox is in sections which can be removed.
Stage 3: The Final Set of Patterns
Once completed the patterns consisted of 2 boxless setups, split patterns and several core boxes.
