Pattern Making
Pattern Making
An accurate pattern is the foundation of an accurate casting
Every casting starts from a pattern — an exact replica of the required shape, imprinted in sand to form the casting cavity. The pattern's accuracy determines the accuracy of every part cast from it afterwards, which is why we make our patterns in-house: we control the dimensions and the shrinkage factors specific to each material (iron's shrinkage differs from steel's and from copper's), and we shorten your lead time because pattern and casting are in one place.
What the service includes
- •Wooden patterns — the most economical for small and medium quantities
- •Metal (aluminium) patterns — for higher accuracy and repeat quantities
- •Pattern made from an engineering drawing (PDF / DWG / STEP / STL)
- •Pattern made from the actual part sample when no drawing is available
- •Storing your pattern for future reorders without a new pattern cost
When it is the right choice
- •A new part cast for the first time that needs a pattern from scratch
- •An unavailable imported spare part — we make the pattern from the sample
- •A worn old pattern that needs re-making to higher accuracy
Our execution steps
Studying the drawing or sample
Determining parting lines, draft angles and core positions if any
Shrinkage calculation
Enlarging the pattern dimensions by the shrinkage factor of the material to be cast
Making and setting
Producing the pattern in wood or metal and reviewing its dimensions
Verification pour
Reviewing the first casting against the drawing before approving production
