The image is an example of cost reduction achieved through the transition to lost-wax precision casting. In the conventional method, production involved multiple processes such as laser cutting, bending, machining, and welding, but we proposed integration through the lost-wax method. Since it can be produced using a single method, it eliminates the hassle of managing processes, reduces machining through integration, and increases strength. Additionally, by checking the contact surface with the object and making that part convex, we have reduced the dimensional management range, making quality control easier. ■Product Details Material: SCS13 (precision casting) Size: 132×100×87 Weight: 763g Thickness: 3.5–5mm Machining: Blue surface 【Castem's Lost-Wax Method】 "Lost-wax precision casting" specializes in hollow and complex three-dimensional shapes.

**Lost Wax Precision Casting by Castem** - Capable of mass-producing complex and hollow shapes at low cost. - Strength can be freely pursued from two aspects: shape and material. - Over 70 types of steel can be freely selected, including special steel, stainless steel, copper alloys, and ultra-high-strength aluminum materials (A7075). - Offers higher precision compared to other casting methods, reducing the number of machining processes. The image shows an example where parts that were traditionally manufactured through machining were switched to lost wax precision casting, leading to **weight reduction and cost savings**. The transition to casting improved mass production capabilities. Unnecessary areas were thinned out, also reducing material costs. Lost wax precision casting excels in producing hollow and complex three-dimensional shapes. We carefully listen to your concerns regarding metal parts and propose the optimal shape. In the example, we reduced the machining area by incorporating fillets (thinning) during the design phase, leading to cost reduction. By making only the functional areas convex, we minimized the machining and management scope. We achieved a shape that is effective in maintaining quality. Depending on the application and size, we can also propose other manufacturing methods such as MIM (Metal Injection Molding), which excels in thin-walled small parts, and mold-less casting digital cast, which is perfect for prototypes starting from one piece.

The image shows an example of a part used in the manufacturing of an elephant trunk (the handle and tip of a rickshaw). The previous material was brass, and it was manufactured through cutting, but it seems the processing company went out of business. After that, it was produced once using sand casting, but it was more expensive and had many defects compared to cutting, which was a problem. Therefore, we proposed digital casting, which can accommodate small lots, and we were able to improve both cost and quality. 【What is Digital Casting?】 A method of producing metal products by creating a resin model with a 3D printer and using it as a prototype, following a process similar to lost-wax precision casting. Castings can be produced in as little as one week, starting from just one piece. We offer proposals that are beneficial even for development and prototyping.

The image shows a case where the mass production capability was improved and lead time was reduced by switching parts that were traditionally machined to the MIM (Metal Injection Molding) method. Additionally, by reducing the material weight by nearly 90g through a process called "de-bulking," cost reduction was also achieved. ◎Product Overview - Material: SUS304L - Size: 40×35×35 - In the case of MIM, the product weight significantly affects the cost, so de-bulking is done as much as possible. 【Castem's MIM Method】 The MIM (Metal Injection Molding) method is a processing technique that mixes metal powder with an organic binder (resin) and injects it into a mold to produce metal parts in the desired shape. It excels in producing fine three-dimensional complex shapes with a wall thickness of up to 5mm and achieves a density of over 95%. It can accommodate orders in the millions and has superior mechanical strength compared to conventional sintered products. We are also advancing the in-house development of compounds made by mixing metal powder and binder, and obtained a U.S. patent in 1991. If you have any inquiries regarding the manufacturing of small metal parts, please feel free to contact us.

The image shows an example of parts made using the lost wax casting method. Traditionally, these were machined parts, but by switching to precision casting using lost wax, we have improved mass production capabilities and achieved lead time reductions. Additionally, by reducing the material weight by over 100g, we have also made cost reductions possible. We are implementing quality measures such as addressing voids by ensuring uniform wall thickness and preventing burrs by creating recesses. ■ Case Details - Transition from SS440 machined parts to SCS14 lost wax products - Size: 84×36×36 - Reduction of over 100g in weight. Cost reduction through material cost savings - Measures against voids and burrs - Preventing burr formation in holes by ensuring that paper does not touch during gate finishing, while maintaining the seating surface of bolts Due to cost considerations, we have received many inquiries from customers considering switching from machining to precision lost wax casting. Depending on the desired size and application of the parts, we can also propose other methods such as MIM (Metal Injection Molding) and digital casting (moldless casting using 3D printed models).

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.
