We will exhibit at Nepcon Japan from January 22 (Wednesday) to January 24 (Friday), 2025 / Display of high-performance rare metal components.

Metals and ceramics: We will propose the optimal heat treatment tailored to your needs!

Generally, high-temperature heat treatment takes several hours, which can be costly and time-consuming. Gakuseki Electric has been conducting heat treatment of high melting point metals and ceramics, including tungsten. In particular, to quickly and efficiently perform heat treatment for small, low-volume, and diverse products, we have repeatedly conducted various experiments and successfully developed a high-speed high-temperature vacuum furnace capable of reaching approximately 2700°C. With this equipment, ■2500°C for 30 minutes ⇒ The entire process from the start of heating to cooling down is completed in about 2 hours! We have achieved efficiency and cost reduction. Additionally, substances that cannot be completely removed in general furnaces can also be heated and removed. ーーー We also accommodate various high-temperature heat treatments, including multi-atmosphere sintering furnaces and forming gas flushing furnaces. Through these high-temperature heat treatments, it is possible to ultimately prevent the residue and contamination of impurities. With decades of accumulated experience and know-how in heat treatment, please leave the heat treatment of metals to Gakuseki Electric. ーーー

• Processing Contract

Contributing to cost reduction with 45 years of technological expertise and original automated equipment.

Tungsten and similar materials have a significant coil back (spring back), but with our years of expertise, we can accommodate various designs and shapes. ◆ We can manufacture a wide variety of coils, from fine wires of a few microns to thick materials. Supported sizes (example): Wire diameter Φ0.01 to 5mm (subject to consultation) ◆ Coiling machine with automatic tension adjustment feature Due to changes in material weight, the back tension differs between the start and end of winding. To produce uniform filaments, a consistent tension must be maintained, and we have our original coiling machine that automatically controls the back tension. ◆ Cost reduction with servo-controlled mandrel-less forming machine For various coil shapes, our NC-type coiling machine allows control simply by inputting design values, making fine adjustments easy. We essentially design all equipment in-house, ranging from fully automatic to semi-automatic machines. ◆ Reliable technological capabilities trusted overseas We have a long history of exporting coils related to lighting and analytical instruments to European and American countries.

From prototyping to mass production of difficult-to-machine materials such as tungsten, molybdenum, and tantalum.

We perform precision machining of difficult-to-cut and difficult-to-process materials such as tungsten, molybdenum, and tantalum. For mass production, we automate the process using feeding machines, while for prototypes ranging from one to a few pieces, we respond quickly with manual operations. In particular, precision machining of small products with tolerances in the micron or millimeter range is our specialty. ◆ Precision machining using NC lathes and other machine tools We utilize NC lathes, MC multi-tasking machines, milling machines, centerless grinders, automatic precision cutting machines, wire-cut and electrical discharge machines, automatic surface grinders, injection molding machines, extrusion molding machines, and presses. ◆ In-house automatic assembly and processing machines We have a wide range of in-house developed fully automatic machines, including fully automatic hot press machines, automatic heater coil assembly machines, and fully automatic electrode assembly machines. Gakuseki Electric often takes on the manufacturing of products that other companies are reluctant or unable to produce. If there are no machines available in the market for manufacturing, we design and build our own processing machines. ◆ Processing - Cutting - Machining - Milling - Cutting - Tapering - Drilling *Sizes, precision, and handled materials are detailed in the "Basic Information" section.

• Contract manufacturing

Ceramics used in high-temperature environments, including electronic components and automobiles. Here are examples of processing alumina, zirconia, silicon nitride, and silicon carbide!

Yakeshi Electric Co., Ltd. offers processing of "ceramics." Ceramics possess excellent wear resistance, heat resistance, and insulation properties, making them suitable for use in electronic components, semiconductor manufacturing equipment, automobiles, and aerospace applications in high-temperature environments. Additionally, ceramic components are strong and have excellent chemical resistance, which allows them to be used in medical devices as well. 【Main Materials Handled】 ■ Alumina (Al2O3) ■ Zirconia (ZrO2) ■ Silicon Carbide (SiC) ■ Silicon Nitride (Si3N4) ■ Quartz Glass (SiO2) *For more details, please refer to the related links or feel free to contact us.

• Ceramics

Our products are used in industrial magnetrons, analyzers, X-ray devices, catheters, semiconductor manufacturing equipment, electric propulsion systems, air purifiers, sterilization lamps, and more.

Rare metal materials such as tungsten, molybdenum, and tantalum, which possess properties like heat resistance, corrosion resistance, and high strength. These materials are difficult to process, and there are only a few companies that handle them. Our company develops and manufactures "functional components" using these rare metal materials, aiming for further improvements in low work function, long lifespan, and high-performance stabilization. ◆ Achievements - Analysis - Mass spectrometers (electron guns, electron sources) - Semiconductor manufacturing equipment - (ion implantation) - Medical - CT scanners (X-ray sources) (catheters) - Space - Ion engines, Hall thrusters (heaters) - High-temperature furnaces - (reflectors) (heaters) (structural components) and more ◆ Technology - Coating (yttria, alumina, PTFE, etc.) - Material development using heat treatment furnaces with a maximum temperature of 2700°C - High-precision, high-aspect-ratio precision machining - Coils of various shapes - Joining of metals and more

• Other inspection equipment and devices

We would like to express our congratulations on the continued prosperity of your esteemed company. Our company will be exhibiting at the following trade show, where we will be showcasing a number of products, including our new product, the Packaging Container Air Leak Test (Pin Hole Inspection) Device | MSQ-2003 series. We sincerely apologize for the inconvenience during your busy schedule, but we would like to cordially invite you to attend this event. 【 Trade Show Name 】 【 Dates 】 【 Venue/Booth Number 】

We will showcase our new product "BLFF," a palletizing foam gripper that weighs only 1.9 kg and measures 350mm×250mm, ideal for bulk picking. We will also introduce various products that cater to different work applications, including durable suction cups and solutions for bag handling. Additionally, we are implementing energy-saving proposals by replacing ejectors to reduce compressed air consumption, which has become a challenge in many industries. If you have any issues with adhesion or transport, please feel free to consult with us at the venue. ■ Lightweight Foam Gripper for Collaborative Robots "CVGC Series" Despite weighing only 1.9 kg, this gripper has a theoretical lifting force of 100 kg, maximizing the payload capacity of collaborative robots. ■ Gripper for Films This gripper is designed to transport thin films gently, minimizing marks left on the surface. By utilizing 3D printing, we can accommodate highly flexible shape designs tailored to specific workpieces and applications. ■ Energy Saving Comparison Panel "Why does a single ejector consume less compressed air compared to a multi-stage ejector?" You can actually verify the differences in compressed air consumption through a comparative display using a flow meter and actual equipment.
