To all those in charge of prototyping, development, and design: Are you still prototyping with "cutting only"?
Prototyping = Breaking the Common Sense of Machining With mold-less casting "Digital Cast", ✅ Supports complex three-dimensional shapes ✅ Delivery in as fast as one week ✅ No mold costs, starting from one piece "When it comes to this shape, machining is impossible..." "The costs are too high to produce in quantity..." In such cases, consider the option of "casting." Digital Cast is a new prototyping method that creates a master using a 3D printer and then casts it. No molds are needed, and we can respond quickly even for just one piece. Over 1,000 successful implementations. Many companies have already broken free from the assumption that "prototyping = machining." Feel free to consult with us first. Your "manufacturing speed" will change.

basic information
**Digital Cast of Castem** ■ Process 1. 3D Printing Shape the model using a 3D printer (resin material). 2. Ceramic Coating Apply 4 to 6 layers of ceramic liquid and powder to the wax tree. 3. Mold Firing Completely eliminate the 3D printed model at high temperatures and fire the ceramic mold. 4. Casting Pour molten metal into the mold. ■ Supported Size Up to 500 mm square. ■ Steel Types We can accommodate a wide range of needs, including iron, stainless steel, aluminum, copper (including pure copper), special alloys (such as duralumin A7075 and nickel alloys), heat-resistant steel, tool steel, and high-speed steel.

Applications/Examples of results
【Examples】 Industrial machinery, semiconductor components, golf club heads, turbochargers, prototype verification of complex shapes, strength verification of cast products, prototype verification with material changes, original parts manufacturing 【Detailed Examples】 ■Cost Reduction of 80% GG Manifold (Aerospace Component) Two parts were manufactured through machining and then welded together. Due to the use of special materials, sourcing from overseas processing companies resulted in higher costs. This was resolved with digital casting. With a wide range of compatible materials and integrated molding, there was a significant reduction in costs along with improved quality due to enhanced strength. Material: Inconel 625, Conventional Method: Machining + Welding ■Short Delivery Time Turbine Impeller Parts (Industrial Turbine) For large parts with a diameter of 380mm, traditional methods required 1 to 2 months for mold production. However, with the digital casting method, cast products can be produced without molds, significantly improving delivery times. Additionally, it can accommodate special materials such as heat-resistant steel and duralumin. Material: SCS13 ■Prototype Verification Vehicle Development Prototypes (Next-Generation Mobility) The initial costs associated with mold production and quality concerns after mold creation were resolved with digital casting. Verification of cast products was conducted without molds, alleviating quality concerns. Material: FCD

Company information
With a posture of "just half a step" without complacency, we have cultivated "lost wax precision casting" over many years. Utilizing 3D printing technology, we offer next-generation precision casting technology called "Digital Cast." We obtained a U.S. patent for "MIM (Metal Injection Molding)" in 1991. We provide optimal proposals using various technologies and thoroughly support our customers' manufacturing! We specialize in complex three-dimensional shapes in small lots of various types and carry out everything from mold making to casting, machining, and simple assembly in an integrated in-house system. We supply products to various industries, including medical devices, semiconductors, machine tools, and aerospace. "Just make it, from one piece." We can propose a wide range of manufacturing methods from prototype production of one piece to mass production. We also enable time savings in searching for various suppliers and considering consultation destinations, becoming a true total cost reduction partner by proposing reductions in management costs related to consideration time and product costs. More than half a century ago, Castem began its casting business by handcrafting machine tools. Today, we have become a leading company in Japan for manufacturing general industrial components using lost wax casting and are also engaged in the production of micro lenses and micro needles using the world's highest precision 3D light shaping technology.
