Day-to-day operating brief
What Pattern Maker work looks like in practice
A Pattern Maker creates and repairs patterns, core boxes and related tooling used to form castings. Terms should identify casting processes, materials, drawings, shrink and machining allowances, draft, parting, identification, inspection, customer tooling and storage. Pattern alterations affect finished geometry and must follow engineering approval rather than workshop intuition alone. Pattern construction must anticipate how moulding and casting change geometry, including shrinkage, draft, fillets and subsequent machining. The maker may use wood, resin, metal or additive methods and should understand how each affects durability and repair. Employers should define storage conditions, lifting arrangements and protection of delicate core boxes. When foundry feedback identifies a defect, any correction should be linked to the casting evidence and drawing authority so repeated adjustments do not gradually move the pattern away from design intent. Pattern identification should survive repair and storage, including ownership, casting reference, revision and orientation, so the foundry cannot select a visually similar but technically obsolete tool. Dimensional handover can include templates, gauges and casting samples, allowing foundry and machining teams to compare physical output with the intended pattern condition after each controlled repair.
