【Manufacturing Method】 Digital Cast (Moldless Casting) 【Content】 This is an example used for vehicle development prototypes. In the process of new development, prototype verification is conducted before mass production! By using Digital Cast, not only can the initial costs associated with mold production be reduced, but quality concerns after mold creation can also be alleviated. 【What is Digital Cast?】 It is a manufacturing method that involves creating a resin model with a 3D printer and then producing metal products through a process similar to lost-wax precision casting using that model as a prototype. Castings can be handled in as little as one week, starting from just one piece. We offer proposals that provide benefits even in development and prototyping. We also accommodate custom orders from individual customers.

A contemporary artist created a glass art piece about 10 centimeters tall, which was 3D scanned and then a 3D printed model was made, enlarged to about five times its original size. The super complex shape, which was accidentally created like candy art, was reproduced through casting. Since the installation location was near water, a highly corrosion-resistant duplex stainless steel "SCS11" was used. The final product was buffed to create a mystical form that blends into the space. 【What is Digital Casting?】 When prototype parts are needed during design changes in development, when there is no stock of parts and urgent replacements are necessary, or when original jigs are needed for on-site work… In such cases, creating metal products through traditional casting methods, considering cost and delivery time, is not a viable option. Therefore, if needed, we offer mold-less casting with the catchphrase "Just make it from one piece!" With no need for molds and zero mold costs, we have a delivery record of as short as one week, and we can custom-make cast products starting from just one piece. Since the original form is a 3D printed item, we can accommodate complex shapes and hollow products that cannot be manufactured with molds. This service is utilized across numerous industries, including aerospace, shipping, automotive, precision machinery, industrial equipment, medical, and construction, catering to requests for metal parts from both corporations and individual customers.

A small-diameter hole shaped like a conical tube, with a tip diameter of φ0.3±0.05 and a length of 2.8 mm, has been achieved without machining. Additionally, there are no burrs inside, and it possesses the necessary strength to prevent chipping or breaking. When dealing with multiple pieces of this shape on a pin cushion through machining, the cost and time are significantly high. With our MIM technology, which allows for ultra-small precision molding, high-precision parts under 1 mm can be mass-produced without machining. 【What is MIM (Metal Injection Molding)?】 It is a method also known as metal powder injection molding. A mixture of metal fine powder and a binder is injected into a mold to create a shaped product, which is then subjected to debinding and high-temperature sintering in a vacuum furnace to produce metal products. We excel at obtaining ultra-small metal parts with high precision, complex shapes, and three-dimensional geometries that are difficult to machine. Our company is the only one in Japan that develops the raw materials used for MIM in-house. We will provide the best proposals for our customers using various technologies. Please feel free to contact us through our website for any inquiries regarding metal parts.

We need precision parts, but machining is costly... Multiple processes such as machining and welding are required, making it labor-intensive... We want to integrate multiple parts... Why not solve these concerns with 【Lost Wax Precision Casting】? 【Castem's Lost Wax Method】 "Lost Wax Precision Casting" specializes in complex three-dimensional shapes. Since our founding, we have continuously responded to customer inquiries for production, achieving over 35,000 types from simple to complex items. In response to various material requests, we have started handling over 70 types of steel, including stainless steel, copper, and aluminum. We also accommodate special steels and ultra-high-strength aluminum alloys (optimizing original casting for A7075). 【Cost Reduction Examples】 The thumbnail shows a cost reduction case achieved by changing the manufacturing method to lost wax casting, resulting in shape modification and integration. In conventional products, we manufactured through multiple processes including laser cutting, bending, machining, and welding, but we proposed integration using the lost wax method. This eliminates the hassle of managing processes between steps, reduces machining, and increases strength. By confirming the contact surface with the object and making that part convex, we reduced the dimensional management range, making quality control easier.

"Castings are not suitable for prototyping or small lot production." —Don't you think so? With Castem's "Digital Cast," you can produce casting parts from just one piece without molds by utilizing 3D printing. It offers high freedom of shape and can significantly reduce lead time, costs, and labor. 【Cost Reduction Example】 The part in the thumbnail is a CG manifold that was previously made by machining two parts and then welding them together. Additionally, due to the special material Inconel 625, it was sourced from overseas processing companies, making it a quite high-cost part in the past. However, by creating it as a single molded piece, we achieved a cost reduction of up to 80% and improved strength. "I want to verify shapes that cannot be achieved through machining" and "I want to test with the same material as the final product." We can solve these development challenges with our next-generation precision casting technology, Digital Cast. If you have 3D data, just leave the rest to us. We will provide precision cast products quickly!

★Comparison of the Differences and Advantages between Moldless Casting "Digital Cast" and Metal 3D Printing "Digital Sinter"! In recent years, manufacturing technology for metal parts has evolved dramatically. Moldless casting methods and metal 3D printing are particularly attracting attention in our technology category. 【Advantages of Metal 3D Printing: Digital Sinter】 ■ Overwhelming Speed Digital Sinter has a lead time of about one week (with the shortest record being two days), making it very advantageous for prototypes and small-scale production that require urgent responses. ■ Strong in Producing Complex Shapes and Small Parts The maximum size it can accommodate is 80mm on each side, but it excels in manufacturing small and complex-shaped parts. It is ideal for small components in medical devices and electronic devices, as well as for developing very small quantities of parts. ■ Specific Steel Type Compatibility The materials that can be used are limited to SINTER T (SUS316L) and SINTER D (pure copper, SUS316L, SUS630). This allows for the rapid provision of difficult-shaped items. *This is a guideline for the maximum size and steel types based on our metal 3D printing service. 【What is the Best Metal Forming for Your Needs?】 We provide the optimal manufacturing method for your project, along with VE proposals, based on the purpose of part procurement (QCD) and specification conditions.
