Achieving short delivery times with the "Digital Cast" method, which uses models created by a 3D printer for casting! For large parts with a diameter of φ380, traditional mold production required 1 to 2 months, but with the Digital Cast method, cast products can be made without molds starting from just one piece, resulting in significant improvements in delivery times. Additionally, we can accommodate special materials such as heat-resistant steel and duralumin. *The product in the photo is SCS13. 【What is Digital Cast?】 When considering costs and delivery times, traditional casting methods that require mold production for mass production are not a viable option. Therefore, we propose mold-free casting with Digital Cast, with the catchphrase "Just make it if you need it, starting from one piece!" With no need for molds and zero mold costs, we have a track record of deliveries in as little as one week, and we can custom-make cast products starting from just one piece. Since the original shape is a 3D printed item, we can accommodate complex shapes and hollow products that cannot be manufactured with molds. This method is adopted in numerous industries, including aerospace, shipping, automotive, precision machinery, industrial equipment, medical, and construction, and we cater to requests for metal parts from both corporate and individual customers.

When you need prototype parts due to repeated design changes during development, when there is no stock of parts and you need a quick fix, or when you suddenly want original jigs for on-site work... Isn't there a limited and fixed mindset regarding the ordering sources and manufacturing methods when the required quantity is small? Considering costs and delivery times, options like mold production for repeat mass production or casting methods for metal products are not feasible, right? Therefore, if needed, we propose mold-less casting with our catchphrase "Just make one if you need it." 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. Our services are utilized across numerous industries, including aerospace, marine, automotive, precision instruments, industrial equipment, medical, and construction, catering to requests for metal parts from both corporations and individual customers.

The "Metal Injection Molding" method is a processing technique that creates metal parts in the desired shape by mixing powdered metal with a binder and injecting it into a mold. It excels in producing fine thin-walled shapes with thicknesses ranging from 0.2 mm to 5 mm. It can accommodate millimeter orders and demonstrates properties equivalent to those of melted materials, such as torsion and bending. With a density of over 95%, the pores take on a round, independent shape, resulting in excellent mechanical strength. During the binder debinding process, high-speed debinding and sintering are performed to minimize the alteration and deformation of the metal powder. Various conditions such as vacuum, reducing atmosphere, inert atmosphere, and high-pressure atmosphere can be precisely controlled, allowing for sintering processes suitable for each type of metal. There are also examples in medical devices and aerospace components, and it can handle a wide range of production from batches of 10 to tens of thousands. 【Features】 ■ Small lot products of fewer than 3000 pieces are supported with low-cost dedicated molds. ■ In addition to standard metal injection materials, a wide range of materials is accommodated. ■ All processes, including precision machining, heat treatment, and plating, are integrated into a single production line. ■ Quick response to low-cost, short lead times, and design changes or corrections. ■ The entire process from mold creation to machining is managed in-house. *For more details, please refer to the related link page or feel free to contact us.

We will introduce cost reduction through lost-wax casting. The cost of mold production is extremely low (about 1/5 compared to molds for plastic parts), and once a mold is made, it is semi-permanent. Design changes and material changes using the same mold are also easy! Additionally, due to processing convenience, components that were previously combined from several parts can now be integrated and manufactured at a low cost. This can lead to significant cost reductions. 【Features】 ■ Design changes and material changes using the same mold are easy ■ Free selection of special steel, stainless steel, copper alloys, and aluminum alloys ■ The cost per product is definitely lower compared to other manufacturing methods ■ Appropriate methods are adopted according to the product, achieving low prices ■ Integration of components that were previously combined into a single unit for cost-effective manufacturing *For more details, please refer to the related link page or feel free to contact us.

Metal injection molding is a processing method that creates metal parts of desired shapes by mixing powdered metal with a binder and injecting it into a mold. Recognizing the rapid trend towards high precision and complex shapes, Castem foresaw this shift early on and focused on the metal injection molding method (MIM), conducting independent research and development without relying on technology imports from the United States. In 1991, they obtained a patent in the U.S. and completed the manufacturing process using metal injection. Since then, they have continued to explore the possibilities of metal injection and have taken on the development of mechanical parts that can only be made through this method. Moving forward, they aim to further enhance their capabilities and respond to the demands for higher precision and complex shapes. For more details, please contact us.

Shape: Complex shapes and three-dimensional curved surfaces can be mass-produced at low cost. Material: Special steel, stainless steel, copper alloys, and aluminum alloys can be freely selected. Additionally, since the same mold can be used for material changes, it is easy to compare and evaluate during the prototype stage. Strength: By integrating adjacent parts and auxiliary components into a single casting, weaknesses caused by assembly and welding can be eliminated. There are no directional weaknesses due to residual stress that occurs in cast products or parts with significant machining allowances. For movable parts, unnecessary inertial forces can be eliminated by reducing weight, which increases durability. Thus, strength can be freely pursued from the two aspects of shape and material. Casting Surface: There are slight differences depending on the casting material, but small parts are around 12S and large parts are around 20S. Accuracy: Compared to other casting methods, the accuracy is high, allowing for a reduction in the number of machining processes.
