High level of quality lost wax technology developed and refined in-house
What We Have
The Lost Wax method provides much higher dimensional accuracy and better surface finishes than conventional casting. It is also possible to mass produce complex shapes, such as a combination of adjacent parts.
In addition, it is possible to handle titanium and other high-level steels, making it possible to select from a much wider range of steels than with die casting, which uses low-melting-point steels such as aluminum and zinc as its main materials.
Lost-wax casting is only one of the oldest casting techniques with these characteristics. However, Castem’s lost-wax technology is not based on American standards, but rather on our own research and development.
We can produce high-precision screws and gears that could only be made by cutting.
The high level of quality of our products is unrivaled in the industry.
What It Brings
[Shape] Can be mass-produced at low cost for complex shapes and those with three-dimensional curved surfaces.
[Material] You can choose freely from a wide range of materials such as special steel, stainless steel, copper alloy, and aluminum alloy. The same mold can be used for material change, so it is easy to compare and contrast the materials at the trial production stage.
[Casting surface]Small parts are about 12S and large parts are about 20S, although there are some differences depending on the material used for casting.
[Accuracy] Higher accuracy compared to other casting methods, which can reduce the number of processing steps.
[Strength] Since adjacent and accessory parts can be integrated into one piece, the weak points of assembly and welding can be eliminated.
As for moving parts, unnecessary inertia force can be eliminated by reducing the weight, which increases the durability.
As described above, strength can be pursued freely from two aspects, shape and material.
How To Be Utilized
Cost reduction by integration: 70% cost reduction
Example of cost reduction by removing meat: 50% cost reduction
The cost of making a mold is extremely low (about 1/5th that of a mold for plastic parts), and once a mold is made, it is permanent. It is easy to change designs and materials using the same mold.
You can choose freely from a wide range of materials, including special steel, stainless steel, copper alloy and aluminum alloy. In addition, the same mold can be used for material change, so it is easy to make comparisons at the prototype stage.
(Prototype stage, small-lot production)
Due to the low cost of the mold, the cost per product is definitely lower than that of other manufacturing methods.
(Mass production stage)
We can provide the most appropriate solution for each product to achieve the lowest cost.
For the sake of engineering convenience, we have been able to integrate several parts into a single unit and manufacture them at low cost. By doing so, significant cost reductions can be expected.
Guaranteed high strength, thin-walled three-dimensional shape allows for product weight reduction.
Complex and irregularly shaped products
We are good at producing complex shapes and irregularly shaped internal structures, and we can design more freely than other manufacturing methods.
Cams and gears
Cams and gears are conventionally machined. However, CASTEM’s loss-waxing method has completely changed that concept.
SKD, SKH and Stellite castings
Steel grades that are considered difficult to cut are significantly more expensive to cut. In investment casting, it is best to follow up with precision machining on material that has been roughly shaped to approximate it.
