Precision Casting Services Via the Lost Wax Investment Technique

In the world of advanced manufacturing, precision components demand exceptional accuracy and flawless surface quality. Our Precision Casting Services utilizing the Lost Wax Investment Technique deliver exactly that - complex, high-tolerance parts with outstanding metallurgical properties, ready for minimal post-processing.

Advanced Materials for Demanding Applications
We process an extensive range of engineering alloys to meet your specific requirements:

• Stainless Steels: 304, 316, 17-4PH for corrosion resistance and strength

• Tool Steels: H13, P20 for durability in demanding environments

• Aluminum Alloys: A356, 7075 for lightweight structural components

• Super Alloys: Inconel, Hastelloy for extreme temperature applications

• Copper Alloys: Brass, bronze for thermal and electrical conductivity

The Lost Wax Investment Casting Process
Our meticulous approach ensures consistent, high-quality results:

1. Pattern Creation

   • Injection molding of wax patterns using precision aluminum molds

   • Assembly of wax patterns into clusters for efficient production

2. Shell Building

   • Successive ceramic coatings applied via dipping and stuccoing

   • Controlled drying between each coating application

   • Final shell thickness tailored to part size and material

3. De-waxing and Firing

   • Advanced steam autoclave systems for complete wax removal

   • High-temperature firing to achieve optimal shell strength

4. Pouring and Finishing

   • Controlled atmosphere melting and pouring

   • Automated shell removal and cut-off operations

   • Heat treatment and surface finishing as required

Key Advantages of Our Process

• Exceptional dimensional accuracy with tolerances up to ±0.005 inches

• Superior surface finishes ranging from 125 to 250 RMS

• Complex geometries with intricate details and thin walls

• Minimal material waste and reduced machining requirements
