We can accommodate various processing methods, such as "vacuum casting," which allows for the production of replicas at low cost!

At our company, we are committed to responding to "the QCD that our customers desire" not only through our own processing but also by collaborating with partner companies. We handle various types of processing, including "resin cutting," which is suitable for products that are not suitable for mass production and for creating high-precision prototype models, as well as "metal cutting," which focuses on machining centers for both prototyping and mass production, using materials such as iron, aluminum, and brass.

Pursuing "speed, proximity, and flow" in small-batch, diverse production! Introducing our strengths.

At the time of our founding, injection molding using standard molds and molding machines was mainstream, regardless of the size of the production parts. However, since our focus was on small parts, we developed molds and injection molding machines tailored to that need. The F cassette-type molds and small injection molding machines were developed to pursue "speed, proximity, and flow" in low-volume, high-variety production, and we were confident that this directly connected to the QCD that our customers demanded. Currently, this method and technology are not considered special, but the ideas and experiences from that time have been inherited in other methods, production, and sales. 【Features of F Cassette-Type Molds】 ■ Developed F cassette-type molds simultaneously with small injection molding machines, reducing equipment area to about 1/10 and using eco-friendly equipment that also reduces energy consumption. ■ Molds have been made lighter, allowing setup to be done by hand only, shortening setup time to about 1/5. ■ Molds are smaller, and even if the production parts change, the cassette part can be used interchangeably, so only the "insert" changes, resulting in good cost performance for mold expenses. ■ In principle, since we flow one piece at a time, even if there are defects, they do not mix with good products, preventing quality inconsistencies. *For more details, please refer to the related links or feel free to contact us.

The equipment area is about 1/10, and energy consumption is reduced, using eco-friendly equipment!

This product features a "F cassette-type mold" that has been lightweighted and can be set up manually. Setup time has been reduced to about 1/5. The mold is smaller, and even if the production parts change, the cassette section remains common, with only the "insert" changing, resulting in good cost performance for the mold expenses. In principle, since it is a single flow, even if there are defects, they will not mix with good products, preventing quality inconsistencies. 【Features】 ■ Equipment area reduced to about 1/10, with reduced energy consumption for an eco-friendly setup ■ The mold is lightweight and can be set up manually ■ Good cost performance for mold expenses ■ No quality inconsistencies *For more details, please refer to the related links or feel free to contact us.

Significant cost reduction from the initial problem! Here is a case study of adding special shapes to pellet-shaped adhesives.

We would like to introduce a case study of the "special shape adhesive" handled by Fujiseiko Co., Ltd. The customer was in a situation where they had no choice but to purchase pellet-shaped adhesive, but they faced the challenge that it could not be used with their machinery in its pellet form. After we proposed modifying the pellet-shaped adhesive into a special shape, the need for retrofitting machines installed worldwide was eliminated, resulting in significant cost savings. 【Case Overview】 ■Challenge - The special shape adhesive used in the machinery became unavailable, forcing the purchase of pellet-shaped adhesive. - The pellet form could not be used with the machinery in operation. ■Result - Achieved significant cost reductions from the initial problem. *For more details, please download the PDF or feel free to contact us.

In construction work, it is important not only to focus on the building itself but also to create a safe environment for construction vehicles and workers to move around. The Hyper CLT plywood is a lightweight wooden board that utilizes CLT. It can be used as temporary materials to support temporary roads, material delivery routes, heavy machinery work yards, material storage areas, and worker pathways, rather than as structural materials for buildings. The 5×10 board weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, or relocate depending on site conditions. This allows for the boards to be moved in accordance with the progress of the construction, making it easier to effectively utilize limited space. Additionally, the natural texture of the wood blends well with construction sites in residential areas and around public facilities, contributing to considerations for metal noise and summer heat reflection. The Hyper CLT plywood is a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system, designated as "TH-250021-A." It can be incorporated into highly public construction projects and exterior and earthworks, promoting the use of new technologies and environmental considerations. Wooden plywood, NETIS, civil engineering, CLT, lightweight wooden boards. A new option for temporary materials using wood is available for construction sites.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create 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 variations in dimensions, can be molded at the same time in a single molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
