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.

We have been involved in the development of the idea "Negakari Bouzu" by Mr. Nakama of Organizational Reform Co., Ltd. 【What is "Negakari Bouzu"?】 A product created to prevent snagging of lures and tackle used in fishing. It is a revolutionary mechanism that can remove snagged hooks by applying force in the opposite direction of the line using a spring. 【Development Background】 The structure uses a spring to apply force in the opposite direction, aiming to reduce environmental impact, costs, and angler stress. Mr. Nakama, who had no experience in manufacturing metal products, collaborated with Castem to develop the product based on a prototype made from paper clay. 1. Shape modification to reduce weight while maintaining strength 2. Design optimization through flow analysis considering the characteristics of casting 3. Design innovations to reduce post-processing such as hole machining Utilizing the casting method "Digital Cast" with a 3D printer, we achieved rapid prototyping without molds. 【From Personal Idea to Market】 A personal idea has been realized through Digital Cast technology and progressed to market deployment. Castem is not just a manufacturing contractor; we are committed to being "the best partner for our customers" and fully support the realization of ideas.

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.

The "Metal Injection Molding" process is a manufacturing method 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 accommodates millimeter-scale orders and demonstrates properties equivalent to those of wrought materials, such as torsion and bending. With a density of over 95% and pores that take on a round, independent shape, it exhibits excellent mechanical strength. The binder debinding process is conducted at high speeds to minimize the alteration and deformation of the metal powder, allowing for sintering under various conditions, including vacuum, reducing atmosphere, inert atmosphere, and high-pressure atmosphere, tailored to each metal's requirements. There are also examples in medical devices and aerospace components, with a wide range of production from batches of 10 to tens of thousands. **Features** - Small lot products of fewer than 3000 pieces are handled with low-cost dedicated molds. - In addition to standard metal injection materials, a wide range of materials is supported. - All processes, including precision machining, heat treatment, and plating, are integrated. - Quick response to low-cost, short lead times, and design changes. - The process is developed in-house. *For more details, please refer to the related link page or feel free to contact us.*

When you need prototype parts while repeatedly making 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 cost and delivery time, options like mold production for repeat mass production or casting methods for metal products are not viable, right? Therefore, if needed, we propose mold-less casting digital cast with the catchphrase "Just make it from one piece." With zero mold costs and a delivery record of as short as one week, you can order custom-made 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.

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 lasts semi-permanently. Design changes and material changes using the same mold are also easy. Additionally, due to processing convenience, parts that were previously combined from several components 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 ■ Parts that were previously combined from several components can be integrated and manufactured at a low cost *For more details, please refer to the related link page or feel free to contact us.
