Don't give up just because it's a small quantity! We can handle everything from a single cast part to mass production. Castem will be exhibiting at the Monozukuri Fair 2026.

That cutting part might be able to reduce costs and processing time? We offer a free assessment of improvement possibilities!

The cost of that machined part may be reconsidered. Metal parts manufactured through cutting processes can sometimes reduce costs and processing time by reevaluating the method. ✔ High cost of machining ✔ Significant material waste ✔ Complex shapes requiring more processing time ✔ Desire to improve lightweight design and mass production Do you have such concerns? At Castem, we offer VA/VE proposal services through the transition to lost-wax precision casting. Based on drawings and 3D data, we will consider the possibilities of weight reduction, material waste reduction, processing time reduction, and improved mass production free of charge. 'Is machining really the best option for this part?' If you've ever felt that way, please take a look.

Proven results in medical device parts and aerospace components. Castem's three mold plans for MIM.

Castem's MIM (Metal Injection Molding) method has a proven track record in medical device components and aerospace parts. However, do you have the impression that MIM, which specializes in complex shapes and small parts, is not suitable for small lots due to "high mold costs for prototypes" or "limited material options"? The MIM method offers three mold plans tailored to your required quantities. 1. "Mass Production Type" for large lots and repeats - Price: From 980,000 yen - Quantity: Up to 100,000 pieces 2. "Simple Type" for small lots and repeats - Price: From 490,000 yen - Quantity: Up to 10,000 pieces 3. "Try and Make Type" for prototypes and ultra-small lots - Price: From 190,000 yen - Quantity: Up to 50 pieces *Conditions apply. Please feel free to contact us for details. 【Features of Castem's MIM】 ✅ Capable of producing fine, complex shapes with a minimum wall thickness of 0.1mm and sharp edge reproduction ✅ Molding of screws and ultra-fine pins without machining ✅ Proven track record in medical devices, dental, food, and aerospace-related components ✅ In-house integrated production system from mold making to processing such as plating ✅ Both domestic and overseas factories have obtained ISO 9001 certification, ensuring reliable quality control.

Screws are also shaped without machining! Leave the fine, thin-walled, and complex-shaped micro metal parts to us.

MIM (Metal Injection Molding) is a technology for manufacturing metal parts by mixing metal powder and binder, injecting them into a mold, and finally sintering them. ✅ Capable of producing fine, complex shapes and sharp edges with a minimum wall thickness of 0.1mm. ✅ Can mold screws and ultra-fine pins without machining. ✅ Proven track record in medical devices, dental, food, and aerospace-related components. ✅ Integrated production system from mold manufacturing to processing such as plating in-house. ✅ Both domestic and overseas factories have obtained ISO9001 certification, ensuring reliable quality control. With ultra-fine molding technology, we can also create miniature tools that move like the real thing, measuring 25mm in length (such as scissors, calipers, and cutters). From limited small lot products to repeat mass production, we can propose mold cost plans tailored to your needs. We have successfully achieved cost reductions through bold design changes from the design stage, with in-house integrated production from mold manufacturing.

Hollow and complex three-dimensional shapes / Cost reduction / Reduction of processes / Compatibility with a variety of steel types… Introducing the strengths of lost-wax precision casting.

The lost wax precision casting method involves injecting wax into a mold to create a product model, coating it with ceramic to form a casting mold, and then casting to produce metal parts. Its strengths are as follows: ✅ Hollow and complex three-dimensional shapes ✅ A diverse selection of over 70 steel types (including iron, stainless steel, copper, aluminum, and special materials such as super duralumin) ✅ Cost reduction achieved through gradual material removal considering productivity ✅ Time savings through a reduction in the number of processes ✅ Small lot production of various types (from dozens to thousands per lot) ✅ Affordable aluminum molds that can be used semi-permanently ✅ Capable of handling items from a few grams to 30 kg (with a specialty size range of 30 to φ300 mm) "If you want to integrate multiple parts," "if you want to increase strength," "if you want to reduce costs compared to machining," "if multiple processes are required for a single part, leading to increased costs and time"… We propose the optimal materials, shapes, and methods tailored to your concerns and requests. *For a list of materials and tolerance tables, click here* → https://www.castem.co.jp/technology/lostwax/ Please feel free to consult us through our website.

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily understandable at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
