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.

Our approach

From requirement to production-ready tooling

Pattern development combines the casting drawing with moulding-machine and foundry requirements.

  1. 01

    Casting review

    Evaluate component geometry, allowances, draft, parting, and core strategy.

  2. 02

    Pattern development

    Prepare the tooling arrangement, mounting plan, and machining references.

  3. 03

    Machining and finishing

    Produce the profiles and functional features, followed by controlled hand finishing.

  4. 04

    Dimensional inspection

    Check key geometry, interfaces, and workmanship against the approved requirement.

Typical applications

Patterns for demanding foundry programs

  • Pump and valve castings
  • Automotive and commercial vehicle parts
  • Industrial housings and covers
  • Heavy engineering components
