aluminum alloys die casting mold release agent

Product Overview

Description

SANDOZ offers high-pressure die casters the most comprehensive product line of liquid and powdered die lubes for aluminum, magnesium, zinc, squeeze and semi-solid casting operations.

 

Driven by our culture of continuous improvement, plus a passion to solve industry problems, SANDOZ created the first effective water-based die lubricant almost fifty years ago. Since then we have continually developed innovative solutions. If customer parts require painting, SANDOZ has the answer with die lubricants that will not interfere with most post-finishing needs. Our die lubricants also offer excellent die release and good lubrication for pins and ejectors while burning cleaner during application.

 

Aluminum is the most commonly used metal in high-pressure die casting. Aluminum alloys commonly contain silicon, copper, magnesium, zinc, manganese and iron. Molten aluminum is corrosive to steel and the reaction is accelerated at high temperatures and pressure, both of which are commonly found in high-pressure die casting. Silicon improves the fluidity and also forms a low-melting eutectic with aluminum. The most commonly used aluminum alloy has a nominal composition of 8.5% silicon and 3.5% copper and a melting range of 540-595°C (1000 – 1100°F). Some alloys have significantly higher melting temperatures and thus pose greater challenges to die lubrication.

 

Today, the demand for more complex aluminum castings and reduced processing times has lead us to develop a range of die lubes that offer increased wetting and film forming at higher die temperatures. For aluminum die casters we have developed die casting lubricants that offer:

• Hotter die surface adhesion
• Reduced time to achieve optimum die lubricant application
• Enhanced solder protection
• Superior release and brighter castings
• Less gas generation and greater protection of the die against pitting and corrosion
