Flow and Solidification Modeling

Prior to pouring any metal, FS Precision Tech invests significant amounts of engineering time to analyze how material will flow and how it will transition from its molten state to solid.  Employment of this advanced modeling technique ensures that FS Precision achieves production readiness for new programs in the shortest possible time.

As a program proceeds through its production life cycle, advanced modeling is also used to improve efficiency, yields, and overall program costs, ensuring that our customers always receive the greatest value for their casting investment.


Rapid Prototype

Prototyping is an important phase in the development of your casting application. We offer a variety of methods to meet your quick turn needs for one to one hundred pieces.

  • Stereolithography (SLA/SLS): Thermojet™ and Quickcast™ methods generate accurate, castable patterns for low volume prototype needs.
  • Machined Wax patterns: Use our 3 and 5 axis CNC’s to create accurate patterns for complex, medium run prototype castings.
  • 3D Wax patterns
  • Rapid Tool: Our tooling center can generate affordable temporary wax injection molds with a variety of methods for prototypes with higher volume requirements.

Our corporate tooling center in Taipei, Taiwan produces CNC machined aluminum and steel tooling for a number of our production and prototyping needs. Lead times are fast and tooling costs are typically 30% – 40% lower than US tool making options.

Complex injection molds, and programs are produced in house at the Los Angeles facility, or subcontracted to our strategic partners.

Wax injection molding is performed on a variety of manual, semi-automated, and fully automated wax injection machines. Controlled environments and wax handling apparatus assure dimensional stability.


Robotic Shell Dip Systems

Six-axis robotic shell dipping is the standard for our volume production lines. Robotic shell dipping and conveyorized dry tunnels ensure the highest degree of product repeatability and process capability.


Vacuum Induction Melting

An alternate melting method for reactive alloys, VIM uses an electric current passed through an induction coil surrounding the crucible. The electromagnetic field produced in the feed stock generates sufficient heat to melt the charge. This method is often preferred for custom alloy applications, and is the foundation of our proprietary process used for producing net shape Titanium Aluminide turbine wheels for turbocharger applications.

Vacuum Arc Remelting

Our standard titanium and zirconium melting method, VAR uses an electric arc between the feed stock electrode and a water-cooled copper crucible to melt the charge in a high vacuum environment.

Gravity Fed Casting

Used with VAR, VIM, and air melt techniques, most applications use gravity and hydraulic pressure to feed molten metal to your parts.


FS Precision is a certified Nadcap welding facility.  We frequently weld to extreme specifications, including AMS and custom specifications certified by aerospace OEMs.


Hot Isostatic Pressing (HIP)

Virtually all of our high technology casting programs, particularly those in aerospace, require hot isostatic pressing (HIP) to improve fatigue endurance limits and other mechanical properties. We provide a full range of Nadcap certified HIP options to 30,000 psi and 2300F to meet your engineering needs.

Vacuum Heat Treatment

A full range of heat treatment services are available to engineer your casting properties. We offer vacuum, and special atmosphere heat treatment processes in accordance with Aerospace Material Specifications, MIL-SPEC, and ASTM specifications.

5 Axis CNC Machining

There are times when your short run production needs may not justify non-recurring tooling expense. As an alternative to 3D Printing we can use 5 axis CNC machined wax for single-setup, automated manufacture of your complex patterns.

Chemical Milling

Our state-of-the-art chemical milling operation was installed in our Los Angeles facility in 2007. It offers fully automated chemical milling of titanium alloy castings to ensure removal of alpha case in accordance with stringent aerospace specifications.

Because we have chemical milling in-house, we are also able to utilize it for special purposes such as surface finish control and dimensional control when appropriate.


Passivation is a chemical surface conversion process that imparts corrosion resistance to stainless steel components. We off contract services to passivate your stainless parts.


Final Finish Machining

We offer grinding, polishing, manual or CNC milling (3, 4, and 5 axis), CNC turning, and a variety of customized assembly and finishing operations to deliver your finished product.

Non Destructive Examination

FS Precision is a certified Level II facility for fluorescent dye penetrant inspection (FPI) and offers in-line, real time digital x-ray inspection for all your casting needs. We can accommodate any level and sensitivity of FPI, radiography, and other inspections in accordance with aerospace specifications.


Dimensional Inspection

Coordinate measuring and White light inspection systems compliment a variety of standard and custom inspection techniques are in place for automated inspection and data collection.
