OEM Aluminum Investment Casting Services with Pressurized Cast Die Mold Making

In the precision manufacturing sector, OEM aluminum investment casting enhanced with pressurized cast die mold technology represents a significant advancement in producing high-integrity components for demanding applications. This sophisticated manufacturing approach combines the dimensional accuracy of investment casting with the enhanced metallurgical properties achieved through pressurized solidification.

Advanced Aluminum Material Engineering

Our investment casting services utilize premium aluminum-silicon alloys specifically formulated for pressurized casting applications. The A356.2 alloy, with its controlled silicon content of 6.5-7.5% and magnesium content of 0.25-0.45%, develops exceptional mechanical properties through T6 heat treatment, achieving tensile strength exceeding 45,000 psi and yield strength of 35,000 psi . For applications requiring enhanced fluidity and pressure tightness, we employ A360 alloy with its superior casting characteristics and minimum tensile strength of 46,000 psi in as-cast condition . Each alloy batch undergoes spectrographic analysis to ensure precise chemical composition control.

Precision Pressurized Casting Technology

Our pressurized investment casting process integrates advanced mold making with controlled solidification:

Precision Die Mold Manufacturing

• CNC-machined mold bases created from P20 and H13 tool steels with hardness ratings of HRC 30-44

• Electrical discharge machining (EDM) producing complex mold cavities with tolerances within ±0.0005 inches

• Multi-slide mold systems enabling undercut features and complex geometries without secondary operations

• Temperature control systems incorporating conformal cooling channels for optimal thermal management

Pressurized Casting Process

• Vacuum-assisted pouring ensuring complete mold filling and reduced gas porosity

• Controlled pressure application during solidification, typically ranging from 20-100 psi depending on component geometry

• Directional solidification enhancement through strategic mold design and thermal management

• Real-time process monitoring tracking temperature, pressure, and cycle parameters for consistent quality

Enhanced Performance Characteristics

Components manufactured through our pressurized investment casting process deliver:

• Superior Metallurgical Integrity: Reduced porosity levels below 1% through controlled solidification under pressure
