Accurate patterns that support stable mould formation
PTPL designs and manufactures aluminum sand casting patterns for foundries that require dimensional consistency, practical handling, and repeatable mould preparation.
Pattern geometry, draft, parting conditions, core requirements, and machine interfaces are considered together. The result is tooling developed to transfer the intended component shape reliably while supporting the realities of foundry production.
Pattern engineering
Geometry is reviewed around draft, parting, machining allowance, and moulding requirements.
Dimensional control
Critical profiles, mounting faces, and references are machined and checked carefully.
Foundry-ready design
Handling, durability, moulding method, and production practicality guide tool construction.
Robust construction
Aluminum tooling provides a stable, maintainable solution for repeat production programs.
From requirement to production-ready tooling
Pattern development combines the casting drawing with moulding-machine and foundry requirements.
-
01
Casting review
Evaluate component geometry, allowances, draft, parting, and core strategy.
-
02
Pattern development
Prepare the tooling arrangement, mounting plan, and machining references.
-
03
Machining and finishing
Produce the profiles and functional features, followed by controlled hand finishing.
-
04
Dimensional inspection
Check key geometry, interfaces, and workmanship against the approved requirement.
