Capacity

With both sand and gravity die castings, we are able to offer the best process for every casting.

Sand Foundry
Haworth Castings use chemically bonded sand systems, which comply with current environmental regulations. This ensures that all sand moulds produced are ecologically acceptable. To achieve optimum results, a variety of sand systems are used.
Sand Systems:
  • Chemically bonded
  • Shell moulded
Sand Grades:
  • 85 and 100 AFS
Alloys:
  • Aluminium specifications:
    • BS 1490 1988
    • DIN 1725
  • Aerospace alloys
  • Bespoke alloys to your specification
Capacity:
  • 500kg maximum
Pattern Systems:
  • The flexible semi-automated system uses fully framed pattern equipment.
  • A loose pattern sampling facility is also available.

 

Gravity Die Foundry
Production methods :
  • Bench
  • Mechanised
  • Hydraulic
  • Tilt pour
Alloys:
  • Aluminium specifications:
    • BS 1490 1988
    • DIN 1725
  • Aerospace alloys
  • Bespoke alloys to your specification
Capacity:
  • 40kg maximum

Shell core moulding is incorporated to enhance the gravity die process
