Even difficult items can be handled with the technology of Hoei Rubber! From molded rubber and resin products to rubber and sponge sheets, as well as composite products made of rubber, resin, and metal!

"Ho-Ei Rubber" is a fabless manufacturer of rubber and resin components. Utilizing our experience and know-how from operating molding factories for rubber and resin, we provide proposals that meet our customers' needs. We handle not only rubber and resin molded products but also cutting of rubber sheets and sponge sheets, as well as composite products made of rubber, resin, and metal. As this involves our proprietary know-how, we cannot provide detailed information, but we have successfully addressed many projects that were considered difficult to realize. If you are facing issues with rubber or resin, please feel free to contact us.

If you're having trouble with resin, please consult Ho-Ei Rubber! We will find a solution.

"How do you make it?" "What materials are good?" "Are there rubber parts as well?" "How should I arrange it?" Do you have any concerns regarding plastics or resins? If you're in trouble, please consult with Houei Rubber. We will find a solution. 【Please leave these kinds of troubles to us】 ■ There are cracks in the resin - We can select the appropriate resin for the intended use and its formulation. ■ It is dented - We can design considering the thickness of the resin. ■ Since the lot is small, I want to keep the mold cost low - We can reduce mold costs by manufacturing with local manufacturers in China. *For more details, please refer to the PDF materials or feel free to contact us.

Fukuda Co., Ltd. has been pursuing leak detection for 60 years and is committed to advancing the future of leak testing. 【 Supporting Various Leak Tests: Air Leak Test / Gas Leak Test (Hydrogen Gas, Helium Gas) 】 We develop, manufacture, and sell leak testing equipment to inspect airtightness and sealing properties. We will propose the appropriate testers and devices for each inspection target. 【 Target Industries and Examples of Inspection Targets 】 - Automotive Industry: Engines, FC components, valves and piping, various parts - Electronic Components Industry: Smartphones, keyless switches, various small sensors - Pharmaceuticals / Food / Cosmetics Industry: Bottle containers, syringes, vials, eye drop containers, pillow packaging, PTP packaging We will propose the most suitable leak testers for each industry. 【 ISO Certification 】JIS Q 9001:2015 (ISO 9001:2015)

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.

The inspection targets of the "MSX-7003 series" are relatively large electronic devices. 【Inspection Targets】 - LED - Optical devices - High-frequency devices - Power semiconductors - IR sensors - Gyro sensors - Angular velocity sensors - Electrolytic capacitors, etc. The transport system is designed based on "pallet to pallet" to accommodate various types of work. The following three processes are performed automatically by the airtight inspection device: - Helium bombarding - Gross leak test - Fine leak test For packaged products smaller than 10 mm on each side, the work is set up using pallets or trays, followed by helium bombarding ↓ Then transported to the leak test process through high-speed handling ↓ Going through a continuous process from the gross leak test to the fine leak test ↓ And finally, discharged onto a pallet through high-speed handling. It also supports inline operations (the height of the pass line is 940 mm). Please watch the YouTube video from the link below.

In battery manufacturing lines, if components containing copper are used, there is a possibility that metal powder may mix in, dissolve, ionize, and pass through the separator, causing a malfunction that connects the positive and negative electrodes. Such minute metal powders may not be detected during pre-shipment inspections, and even if they are found, they can lead to various issues, such as the need to increase inspection processes to detect them. Therefore, Fukuda has developed a copper-free (all stainless steel) air leak tester that can be safely used in the production lines of battery manufacturers and secondary battery manufacturing equipment manufacturers. For product specifications and details, please refer to the "Related Product Information" and "Related Catalogs" below.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
