Mett-Bio Metallurgical Testing and Analysis is an independent R&D division with ISO 17025:2017 (NABL) accreditation, located in Ahmedabad, India. is involved in corrosion testing and failure analysis since 2013.

We are glad to announce Corrosion Test Coupons, an inexpensive online monitoring tool that will allow you to properly monitor corrosion within your systems. The mile per year corrosion rate of an exposed coupon can be used to easily determine the materials life.

Mett-Bio can help you manufacture coupons in any shape, size, and material (ferrous, non-ferrous, and elastomeric). Depending on the requirements, a suitable marking can also be stencilled on the coupons. Typical coupon shapes include flat strip coupons, disc coupons, and cylinder coupons. Mett-Bio provides a variety of coupon holders and can also develop and manufacture custom holders to meet specific requirements..

Versatile Material Selection

Choose from industry-trusted materials such as Phenolic, Nylon, FRP, Polyester, and PTFE to meet the specific electrical and mechanical requirements of your project. Each material offers unique advantages in flame resistance, dielectric strength, and environmental stability, ensuring optimal performance for your application.

Custom Shapes & Sizes

Our insulators, washers, and spacers are available in both standard and custom dimensions, ranging from M2 to M12 and thicknesses of 1 mm to 20 mm, with heights up to 50 mm. Shapes include round, square, and custom designs, offering maximum flexibility for panel assemblies, PCB mounting, and equipment isolation.

Reliable Performance in Challenging Conditions

Designed to withstand temperatures from -40C to +150C and humidity up to 95% non-condensing, these components deliver consistent electrical insulation and mechanical separation. Manufactured to tight dimensional tolerances (0.05 mm), they ensure long-term reliability in harsh industrial and electronic environments.

FAQ's of Insulators, Washers, and Spacers:

Q: How are your insulators, washers, and spacers typically used in electrical and mechanical assemblies?

A: Our products are designed for uses such as electrical insulation, hardware spacing, panel assemblies, PCB mounting, and equipment isolation. Their excellent dielectric properties and non-conductive materials make them ideal for these roles where safety and precision are paramount.

Q: What materials and colors are available for customization?

A: Customers can select from Phenolic, Nylon, FRP, Polyester, and PTFE, in natural, white, black, or other custom colors upon request. This range allows clients to match both technical and aesthetic requirements for their specific projects.

Q: When should I select a particular material for my application?

A: The material choice depends on your application's needs for flame resistance, dielectric strength, water absorption, temperature tolerance, and compatibility. For example, PTFE and FRP work well in high-temperature and high-dielectric scenarios, while Nylon and Phenolic are suitable for general electrical insulation and mechanical strength.

Q: Where can these components be integrated within equipment?

A: Their mounting options include through-hole and surface mounting, making them suitable for use inside control panels, electronic devices, PCB assemblies, and any setting that requires hardware spacing or electrical isolation.

Q: What is the typical manufacturing process for your insulators, washers, and spacers?

A: We manufacture these components using precision machining, stamping, or molding processes, depending on the material and required geometry. Dimensional accuracy is maintained to within 0.05 mm, and quality checks are performed to ensure compliance with ROHS, REACH, and UL94-V0 (where applicable) standards.

Q: How does the flame resistance and dielectric strength benefit my application?

A: With UL94-V0 (material-specific) flame resistance and dielectric strength above 18kV/mm, our products provide critical protection against electrical arcing and fire hazards, improving safety and device longevity in high-voltage or sensitive electrical environments.

Q: What packaging and batch sizes are offered to suit different project needs?

A: We offer bulk, small pack, and customized packaging solutions, as well as flexible batch sizes according to client requirements. This ensures ease of handling, storage, and seamless integration into your manufacturing process.
