Precision, Quality and Price Flexibility

Lost wax casting is also called as investment casting dating back almost 6,000 years is one of the oldest techniques produce precision components. It reduces machining costs and produces an excellent surface finish. CASTEM’s lost wax casting has improved in our own way, developing the basic technology established in the U.S. 


Dimensional accuracy is excellent, compared with other investment casting, result in less total number of required processes. Offers finer casting surface then traditional casting. Lost wax products are highly accurate producing superior finish (120 to 150 RMS) from a variety of alloys with excellent tolerance ±.005.

Shapes + Materials

Lost Wax can produce intricate forms with a variety of complex shapes for multiple applications ranging from turbine blades to small precision parts. Applicable materials are much more diverse than die casting, such as low and high melting metals including titanium, aluminum, copper alloy, etc. 

Cost Effective

Lost wax is highly cost effective in that there is no expensive machining costs while reducing waste material. It provides flexibility in design and reduces the costs of changes compared to machine design. Integrated complex-shaped parts can be mass produced.


Neighboring or attached parts can be integrated into a single part. Weaknesses caused by assembly or welding can be eliminated.As for moving parts, unnecessary inertia force can be eliminated, and the durability can be increased by weight reduction. So the strength can be pursued from shape and material point of view

Investment Casting Production Flow

Let us show you how we can provide excellent quality while reducing costs of you current machined component regardless of volume.

Cost Reduction

There are many options we at Castem offer to reduce cost.


Cost Reduction by Integrating Parts


Cost Reduction by Shape Optimization

  • Die/mold production cost is low (about 75% lower than die/mold costs for plastic parts). Die/mold is semi-permanent once it is made it is easy to change design or change materials, using the same die/mold.
  • Choice of a wide variety of materials, such as special steel, stainless, copper alloy, aluminum alloy, etc. Materials can be compared using the same mold during the development process.
  • Trial Process, Small Lot Production: Due to the low die/mold cost, per-piece price is lower than comparative manufacturing methods.
  • Quantity Production When production is scaled up by selecting the most effective casting system costs can be easily controlled.
  • Casting Integrating parts as a single piece reduces costs and time.
