Plastic-to-metal seals (PTMS)

 

Precise sealing and connection solutions

Electrovac Components develops and manufactures high-quality metal components for the plastic-to-metal seals (PTMS) sector. The components are primarily functional elements that are permanently and tightly integrated into plastic.

This technology enables compact, resilient, and media-resistant components for demanding technical applications.

This is a plastic-to-metal seal (PTMS)

A plastic-to-metal seal (PTMS) is a component in which a metal part is firmly and tightly embedded in plastic. This connection ensures that media such as air, gases, or liquids cannot escape, even under high pressures, temperature fluctuations, or chemical stress.

The plastic provides the sealing function and insulation, while the metal ensures stability, precision, or electrical functionality. The firm bond between both materials creates a durable, reliable, and space-saving component used in many technical applications—for example, in sensors, electrical feedthroughs, or medical devices.

Technology for the highest requirements

The use of modern hybrid and injection molding technologies creates PTMS with high process reliability as well as excellent pressure, temperature, and chemical resistance.

The combination of metal and plastic allows for functional integration, reduces installation space, and increases reliability in use.

Applications and industries

Plastic-to-metal seals are used wherever reliable tightness and mechanical stability are crucial—including sensor technology, electrical engineering, medical technology, and aerospace. The PTMS are precisely tailored to the respective application and the media used.
