In the fields of precision machinery and medical devices, precision management at the micron and nano level is essential. A key component in this is the micro-diameter pin gauge. In particular, pin gauges made of cemented carbide excel in wear resistance and strength, enabling stable measurements. Micro-diameter pin gauges have a diameter of approximately 0.01 to 0.099 mm. The diameter of a human hair is about 0.08 mm, making it possible to accurately measure dimensions even finer than that. **Strengths of Cemented Carbide** Cemented carbide, primarily made from tungsten carbide, possesses high hardness and wear resistance. Compared to ceramic materials, it has higher rigidity, maintaining dimensional accuracy even with repeated measurements and long-term use. **Manufacturing Technology** - Ultra-precision finishing with an outer diameter tolerance of ±0.1 μm - Capable of mass production from a minimum lot of one piece **Applications** - Medical field: Measurement of catheter components and plungers in artificial dialysis devices - Semiconductor field: Positioning verification of chips and substrates - Energy field: Precision verification of fuel cell components - Research applications: Evaluation of microfluidic devices and microfabrication **Business Benefits** - Long lifespan contributes to cost reduction - High-precision inspections reduce product defect rates - Custom specifications allow for flexible responses to research and development projects

In applications where high hardness, wear resistance, and chemical stability are required, zirconia ceramic pin gauges are an effective choice. Here, we will clearly explain the features of zirconia pin gauges, their differences from carbide pin gauges, and examples of applications. **Features of Zirconia Pin Gauges** Zirconia is a ceramic with the following characteristics: - High hardness and excellent wear resistance - Non-magnetic and electrically insulating - Excellent corrosion and chemical resistance - High dimensional stability due to thermal expansion rate being close to that of metals These characteristics make them effective in the following situations: - Measurement of non-magnetic parts in contact with metals - Measurement in corrosive liquid or chemical environments - Precision measurement applications where even slight displacements matter - Manufacturing processes that require clean environments and electrical insulation **Differences from Carbide** **Advantages of Zirconia:** - Non-magnetic and does not conduct electricity - Strong against chemicals, with a long lifespan even in corrosive environments - Smooth surface with minimal foreign matter adhesion - Less prone to fine dimensional changes due to wear **Advantages of Carbide:** - Slightly superior impact resistance and breakage resistance - Relatively low cost - Extensive processing track record and availability If you are struggling with the selection of materials and specifications for pin gauges, please feel free to consult with Sanwa Creation.

Here are the benefits of purchasing a pin gauge set: 1. You can have multiple sizes at once. The pin gauge set includes sizes within a certain range (which can be selected at your discretion), allowing you to quickly choose the appropriate size for your needs. This saves you the hassle of purchasing individual pieces each time you need them. 2. Improved efficiency in measurement tasks. Many sets come with sizes in increments of 0.01mm or 0.05mm, making it easier to check hole diameters and machining accuracy. This reduces the time spent searching for sizes each time you measure, enhancing work efficiency. 3. Easy storage and management. Sets often come with a dedicated case, which helps prevent loss and makes management easier. Purchasing items individually can complicate management, but with a set, you can store them in order, simplifying size management. 4. Versatile for a wide range of applications. With a set, you can quickly select the appropriate size from your collection even if you need to measure an unexpected size. This flexibility is particularly beneficial in prototype and research and development settings, where you may need to respond to unforeseen measurement needs.
