Injected aluminium cast iron

Challenges in Casting & Die Casting:

1. High Temperatures
   Molten aluminium (around 660°C) and iron (1,200-1,500°C) require lubricants that can withstand extreme heat without breaking down. Regular oils burn away too quickly.
2. Sticking & Soldering
   Molten metal tends to stick to molds and dies, causing surface defects. Special lubricants create protective barriers to prevent this fusion.
3. Wear & Corrosion
   Abrasive materials in casting processes wear down equipment. Some lubricants can also cause corrosion if not properly formulated.
4. Release Performance
   Good lubricants help separate finished parts from molds cleanly without damage or residue buildup.
5. Dimensional Accuracy
   Proper lubrication ensures even cooling and prevents warping or porosity in final products.

Brugarolas Specialty Lubricant Solutions:

• For Casting (Sand/Gravity/Investment):
  – Mold release agents using graphite or silicone bases
  – Heat-resistant coatings for iron molds
  – Water-based sprays with anti-weld additives for die casting
• For Die Casting:
  – Semi-synthetic fluids with extreme-pressure additives
  – High-temperature greases for plunger systems
  – Glass powder lubricants for very high temperatures
• For Extrusion/Forging:
  – Clean synthetic lubricants that don’t stain
  – Special formulations that produce minimal smoke

Benefits:
– Tools last 30-50% longer
– Better surface quality on finished products
– Lower energy use due to reduced friction
– Safer, more environmentally friendly options available

Example: Proper lubrication can extend a die’s life from 50,000 shots to over 200,000 shots in aluminium die casting.
