タカイコーポレーション Product Lineup

**Reasons for Being Able to Accommodate Small Lots** "We can't find the screws we need," "Mass production is unnecessary, but high precision is required." In response to such concerns, Takai Corporation offers individualized solutions. We accept the production of special screws, such as low-head screws, tamper-proof screws, as well as unified, pipe, and fine-thread screws, starting from just one piece. After carefully considering the desired material, strength, and processing method, we propose products that optimize both durability and cost. **Optimized Processing Proposals Tailored to Requests** Our strength lies not just in manufacturing, but in proposing materials and processing methods tailored to the application and durability requirements. For example, for medical devices, we suggest screws that prioritize insulation and chemical resistance using PEEK. We select processing methods that address the challenges of each usage environment, such as transport equipment, measuring devices, and semiconductor-related applications. We also offer a wide range of heat treatment and coating options. **Custom Solutions for Small Lots Capturing Market Needs** When off-the-shelf products don't fit, and other companies can't meet the lot requirements, we can handle everything from prototyping to mass production in stages. Especially for prototypes in the conceptual stage or small lot requests, our sales, design, and manufacturing teams work together to enable quick turnaround times.

In semiconductor manufacturing, as miniaturization and high integration progress, even a small amount of metal powder or wear powder can lead to contamination, which directly affects yield. Our ceramic pin spring plungers are specially designed components that achieve clean contact through non-metallic materials, contributing to the improvement of quality and reliability in semiconductor processes. Reasons why they are optimal for semiconductor processes: Zero metal powder - The definitive solution for contamination prevention. The generation of wear powder, which could not be avoided with conventional metal pins, is significantly reduced through ceramicization. High wear resistance and long-term stable operation. Due to the high hardness of ceramics, wear and deformation are almost nonexistent, maintaining the shape accuracy of the contact parts over an extended period. Dimension stability even in high-temperature processes. With low thermal expansion, performance is maintained even in high-temperature environments. Safety design through insulation. Being completely non-conductive prevents shorts and electrical issues. Cleanroom compatible with high purity and low outgassing. Impurities are extremely low, and outgassing is nearly zero.

This is the world's first all-SUS316 ball plunger, made entirely from SUS316 material, which excels in corrosion resistance and chemical resistance, used in the body, ball, spring, and spacer. It demonstrates stable holding power and positioning performance over long periods, even in corrosive and chemical environments where conventional products struggled. SUS316 achieves superior corrosion resistance compared to SUS304 by including molybdenum in addition to chromium and nickel. It particularly excels in durability under chlorine environments and chemical atmospheres, suppressing rust and degradation. ■ Features - All-SUS316 structure: All components are made from corrosion-resistant materials, minimizing corrosion risk. - High chemical resistance: Usable in environments with acids, alkalis, and cleaning chemicals. - Long lifespan design: Maintains stable spring performance even in harsh environments. - Wide range of sizes: Compatible with sizes from M3 to M16, applicable to various designs. This is a new option that significantly improves design flexibility and reliability in environments that are challenging for conventional materials, such as "corrosion," "chemicals," and "high humidity." Please make use of it in mechanical design under harsh conditions.

A stop bolt with a PTFE pad developed for semiconductor manufacturing equipment and vacuum devices. The tip pad uses fluororesin (PTFE), while the bolt body is made of SUS316(L), which has excellent corrosion resistance. The main feature is a mechanical fixation structure that does not use any adhesives, which suppresses outgassing and is ideal for clean environments. PTFE has a heat resistance of approximately 260°C and excellent chemical resistance, maintaining stable performance even in acidic, alkaline, and solvent environments. Its low friction characteristics prevent scratches on the workpiece, making it ideal for precision positioning applications. Compared to conventional urethane and POM pad products, it significantly improves reliability in high-temperature, chemical, and vacuum environments, making it a high-performance positioning stopper.
