In response to various material requests, we have started handling over 70 types of steel, including stainless steel, copper, and aluminum. Of course, we also accommodate special steels and ultra-high-strength aluminum materials (optimizing original casting for A7075). 【Cost Reduction Examples】 The thumbnail shows a cost reduction case achieved through shape modification and integration by switching to lost wax casting. 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, reduces machining, and enhances strength. By checking 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. The freedom of shape is also high, and you 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 processors, making it a quite costly 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. "Shapes that cannot be achieved by machining" and "I want to verify with the same material as the final product." We can solve such concerns in the development field with 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, the manufacturing technology for metal parts has evolved dramatically. Moldless casting methods and metal 3D printing have particularly garnered 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 square, 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 very small quantities of development parts. ■ Specific Steel Type Compatibility The available materials are limited to SINTER T (SUS316L) and SINTER D (pure copper, SUS316L, SUS630). This allows for the rapid provision of complex-shaped items. *Note that this is a guideline for the maximum size and steel types based on our metal 3D printing service. 【What is the Best Metal Fabrication for Your Needs?】 We will provide the most suitable manufacturing method for your project, along with VE proposals, based on the purpose of part procurement (QCD) and specification conditions.

【Cost Reduction Examples through Shape Modification and Integration】 In conventional products, manufacturing involved multiple processes such as laser cutting, bending, machining, and welding. However, we proposed integration using the lost-wax method. Since it can be produced using a single method, it eliminates the hassle of managing processes between steps, reduces processing 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. 【Castem's Lost-Wax Method】 As a lost-wax manufacturer, we have a cumulative record of over 30,000 molds, making us the leader in the industry. We excel in producing both simple shapes and complex three-dimensional shapes, including hollow, undercut, and gear shapes. We can accommodate various materials, including iron-based, stainless steel, copper, aluminum, and some customer-specified materials.

Traditionally, it was a machined product, but by switching to the MIM (Metal Injection Molding) manufacturing process, mass production efficiency has improved and lead times have been reduced. Additionally, we have achieved cost reductions by reducing the material weight by nearly 90g. 【Castem's MIM Process】 The "Metal Injection Molding" process is a manufacturing method that creates metal parts of the desired shape by mixing powdered metal with a binder and injecting it into a mold. With a density of over 95% and pores taking on a round, independent shape, it exhibits excellent mechanical strength. The binder debinding process is performed at high speed to minimize the alteration and deformation of the metal powder, allowing for sintering under various conditions such as vacuum, reducing atmosphere, inert atmosphere, and high-pressure atmosphere, tailored to the specific requirements of each metal. 【Features】 ■ Small lot products of fewer than 3,000 pieces are handled with low-cost dedicated molds. ■ Wide compatibility beyond standard metal injection materials. ■ All processes, including precision machining, heat treatment, and plating, are carried out in-house. ■ Quick response to low-cost, short lead times, and design changes. ■ We have a system in place to develop the processes in-house.

【Short Delivery Time Response】 Lead time can be as short as 2 weeks (with the fastest record being within 5 days). Generally, casting methods from mold production take 1 to several months, but this technology allows for speedy progress, helping to shorten development periods and construction times. 【Wide Range of Metal Materials Supported】 Digital casting allows for the selection of over 70 types of materials (casting materials). This includes not only common materials such as iron-based, stainless steel, aluminum, and copper (including pure copper), but also special alloys (such as duralumin A7075 and Inconel), heat-resistant steel, tool steel, and high-speed steel. It provides designers with flexible options. 【Manufacturing Capable of Small to Medium and Large Parts】 With the ability to accommodate sizes up to 500 mm square, it is ideal for manufacturing small to medium and large parts. This enables the integrated manufacturing of large machine components and parts with complex or hollow shapes. 【Rational Prototyping Verification Aimed at Mass Production Casting】 For mass production repeats, molds are created using the lost-wax precision casting method (our core technology), and prototyping verification with similar cast products before manufacturing is a rational method for evaluating mechanical properties (such as strength confirmation). *The feasibility of support and lead time estimates may vary depending on size, shape, specifications, and quantity.

Parts that are being machined and assembled may have the potential for cost reduction. By integrating shapes made up of numerous parts, we aim to achieve cost reduction. It is also possible to reduce weight and costs by eliminating joint areas that were necessary for assembly. 【Shape】 Complex shapes and those with three-dimensional curved surfaces can be mass-produced at low cost. 【Material】 You can freely choose from special steel, stainless steel, copper alloys, and aluminum alloys. Additionally, material changes can be made using the same mold, making it easier to compare and evaluate during the prototype stage. 【Strength】 Since adjacent parts and attached components can be integrated and cast, we can eliminate weak points caused by assembly and welding. For movable parts, weight reduction can eliminate unnecessary inertial forces, increasing durability. Thus, strength can be freely pursued from both shape and material perspectives. 【Casting Surface】 There may be slight differences depending on the casting material, but small parts are around 12S, and large parts are around 20S. 【Precision】 Compared to other casting methods, the precision is high, allowing for a reduction in the number of machining processes. We will consider and propose appropriate shapes together, so please feel free to consult with us first.
