Two sample prototypes of hairpin stators: <X pin, U pin>

Mainly responding to requests for prototype samples of stators for EV motors! Progressing prototypes in the best possible way for various sizes and wire shapes.

We would like to introduce our "stator sample prototyping" services. Generally, as part of the mass production plan, prototypes of "samples by development phase (so-called A, B, C samples)" are created. After prototyping and verifying the initial A sample, B samples (for performance and functionality verification) are designed and prototyped based on the issues identified. Furthermore, taking the results into account, C samples (prototypes close to mass production specifications) are prototyped, which is a typical phased development flow. 【Features】 ■ We have received orders from several major domestic companies, and we are particularly confident in our high production technology using hairpin flat wire. ■ We have experience in producing stators using not only copper wire but also aluminum flat wire. ■ While we do not have experience in prototyping W pins, it may be possible depending on the request. ■ Production of X pin stator assemblies. ■ Evaluation of forming and welding of aluminum flat wire. \ For more details, please check "Download Catalog" /

Light shaping prototype

It is used for a wide range of applications as a master model for small-scale production such as vacuum casting and molding!

"Light shaping" is a method of creating three-dimensional objects by hardening the surface of liquid resin, which cures when exposed to laser light, using numerically controlled laser beams. This method allows for rapid production and offers many advantages, such as faithfully reproducing CAD data and easily creating scaled models, making it widely used as a master model for small-scale production applications like vacuum casting and molding. Please feel free to contact us when you need our services. 【Features】 ■ Capable of producing necessary models in a short period ■ Can faithfully create three-dimensional models from CAD data ■ Easily produces scaled models ■ Quick production time makes it easy to identify issues *For more details, please refer to the PDF materials or feel free to contact us.

Engine block crack repair MS method cast iron crack repair cast metal prototype

We will repair cracks in metal and machinery without applying any heat. Since no heat is applied, there is no distortion at all.

【Product PR】 The "MS Method (Mechanical Stitch)" is a revolutionary repair technique (Mechanical Stitching Method) that uses mechanical methods to address metal cracks. Since it does not apply any heat, there is no "thermal distortion." It prevents residual stress in other areas and avoids secondary damage such as new cracks. Metal cracks are one of the concerns in equipment maintenance operations. In typical welding repair methods, the base material around the crack changes due to heat, leading to residual stress and distortion, which always carries the risk of "crack recurrence" and "secondary damage." 【Features of the MS Method】 ■ No hardening or residual stress from heat ■ Elimination of secondary damage ■ Maintenance of stable quality → Integrated system repairs using jigs, etc. → Accumulation of know-how, experience, and track record ■ Completion of work in a short period → No significant decrease in equipment operating rates ■ Advantages in safety and environmental aspects → No use of fire, so there is no impact on the operating rates of other equipment or the environment For more details, please contact us.

Casting replacement prototype aluminum prototype cast iron prototype casting mass production prototype

Are you having trouble with the delivery time for your cast metal prototypes? "Casting prototype service!" for cast iron, aluminum castings, and stainless steel castings (lost wax casting)!

● 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 created in a single molding process. This allows for the verification of multiple types in a short period.

Permanent measures for repairing screw holes and bolt holes!!

【Product PR】 "MS Insert" is a female threaded part designed to repair damaged bolt holes. An insert utilizing a special structure on the outer diameter thread is embedded into the bolt hole area for restoration. It is difficult to pull out and does not impose a load on the base material, making it suitable for installation in areas that are constantly exposed to vibrations or at the ends. Compared to conventional products such as spring-type coils and self-tapping items, it improves precision and demonstrates groundbreaking effectiveness in terms of durability. Additionally, by pre-installing it in areas where bolts are frequently attached and detached, permanent measures can be implemented. 【Features】 ■ Difficult to pull out and does not impose a load on the base material ■ Ideal for permanent measures for threaded holes ■ Can be used to strengthen and restore threads ■ Enables installation at ends → Designed with upward-facing threads that pull the surrounding base material towards the center of the screw from all directions For more details, please contact us or download the catalog.
