Gulf Metal Foundry

We maintain high standards of excellence from design and simulation to product delivery. Our castings are manufactured through advanced but rigorously supervised processes.

GMF manufactures sand castings for major industries like oil & gas, power, chemical, engineering.

Advance technology, technical knowhow and engineering excellence has led us to manufacture a bespoke range of sound quality castings.


Our Process

Profitable casting production is achieved by adopting engineering excellence and developing a high degree of melt, rigging, gating and risers optimization. It is also important to avoid macro shrinkage and casting defects besides ensuring proper evaluation of stress and temperature induced distortions. GMF is well-equipped with industry specific engineering tools and software to conduct feasibility studies.

  • GMF engineering works on Magma soft 5.3 modules and conducts comprehensive Thermal and Solidification analysis. Magma soft enables us to conduct studies on melt inoculation, pouring and ladle

characteristics, predict possible sand casting defects, centerline quantification, as well as analyse stress and shrinkage, thermal and mechanical properties after heat treatment.

  •  Simulation Systems and Design Data integration with DELCAM Software
  • 3D Scanning and 3D Modelling – Reverse Engineering productions
  •  Stress module and Solid work
  • CAD and Pro E Software

Major Technological advancements leveraged to manufacture complex castings and enhance the casting quality.

Our Process

Our leading edge is the in-house pattern shop facility which has experienced draftsmen and craftsmen to produce seamless quality patterns with accurate dimensional tolerances.

  • Capability to produce wooden patterns in high quality plywood as well as aluminum patterns.
  • Dedicated CNC flexicam pattern manufacturing machine
  • Experienced pattern development team for design and methoding


  • Dedicated team for pattern modification and ensures dimensional and shrinkage allowances for the same pattern, used for different material grades.
  • High quality plywood is used with longer sheer life and minimum deformation
  • Dedicated pattern storage area. GMF has over 6000 patterns stored in-house.
Our Process

GMF can produce castings from few kilos to 4 tonnes as a single piece. With a unique combination of automatic moulding line conducive for high volume production and hand moulding skills for a bespoke range of castings, we have a leading edge that enables us to be a preferred supplier for casting requirements.
