A flexible shaft is a flexible metal drive shaft. It is generally made by winding multiple layers of hard steel wire, typically made of steel or stainless steel, with a diameter of around 0.5 to 1 mm, into a shaft shape. It combines moderate flexibility with high durability, allowing it to respond to bending and twisting while accurately transmitting rotational motion. Main Features: Flexibility: Can bend and twist, making it usable in narrow spaces and complex paths. Durability: Made of metal, it is resistant to deformation even after long-term use. High transmission efficiency: Capable of efficiently transmitting rotational motion. Depending on the material and design, flexible shafts possess performance that can withstand various applications. Our flexible shafts have high reliability in both torsional fracture resistance and rotational resistance torque characteristics, successfully reducing vibration and heat generation associated with rotation. As a result, we have achieved a wide variety of options to accommodate all applications.

Taisei Monac Co., Ltd. is a machinery parts manufacturer with its headquarters and factory located in Higashi-Osaka City, and its own factories in Taiwan and China. In the field of sintering and powder metallurgy, it has manufacturing equipment for powder metallurgy such as molding, sintering, and heat treatment furnaces at its Taiwan factory, primarily producing sintered parts such as clutches, gears, sprockets, rotor pumps, cams, and oil-impregnated bearings in-house. The production in Taiwan allows for low costs (especially for molds) and small lot production. As a development-oriented company, it is currently engaged in research and development of high-density sintering that achieves a density of over 7.5 g/m³ using soft magnetic materials for molded powder magnetic cores and sintered joints.

The separately molded sintered bodies are temporarily joined with convex and concave shapes and then sent to the sintering furnace for bonding.

The axial gap motor is a type of motor that consists of a rotor and stator with permanent magnets arranged on a disk in a direction perpendicular to the rotation axis. The axial type can maintain a high torque even when made thinner, as the gap area does not change. Additionally, it is possible to stack the motors themselves to increase torque. There is growing expectation for its application in the demand for thinner and higher torque motors in recent years, such as in-wheel motors for electric mobility, joint motors for industrial robots, drone propellers, and pumps.

• Brushless DC Motor

A magnetic core with high shape freedom and low iron loss in the high-frequency range is produced using powder metallurgy of soft magnetic composite materials. By compressing powdered materials, it is possible to optimize the core shape, achieving miniaturization and high efficiency of motors. Additionally, by applying an insulating coating to the soft magnetic powder material, eddy currents generated as the rotation speed increases are suppressed within the powder.

We have achieved high-density sintering with a sintering density of over 7.5 g/cm³ using our unique powder production technology. Conventional sintering typically has a density limit of around 7.2 g/cm³, which is lower than the density of common steel materials at 7.8 g/cm³, resulting in inferior mechanical properties. On the other hand, while Metal Injection Molding (MIM) achieves a density of over 7.5 g/cm³, it faces challenges such as high shrinkage rates, low dimensional stability, and expensive unit and mold costs. High-density sintering is a new technology that resolves the issues of conventional sintering and MIM by achieving a density of over 7.5 g/cm³, with low shrinkage rates and high dimensional stability, all at a low cost.

35 years of design model production. For machining, we receive drawings or CAD data, create machining data at Daisei Monac, and complete the final product through processes such as machining, hand finishing, and painting. In casting, we have successfully developed unique equipment that significantly reduces the air bubbles generated during the molding process.
