Finishing Process

Sintering

GMT’s sintering operations allow us to create a wider variety of material to meet specific demands of many high-performance applications. Typically, the sintering process enhances desirable properties of the material such as strength, electrical conductivity, and thermal conductivity. This can be particularly effective in filtering applications where material strength can be enhanced while maintaining porosity. Sintering is also useful in applications where fall-out of filter media is a concern.

Sintering can also create high volume, low-density forms.

Calendaring

A textile finishing process useful for ensuring the material has a uniform surface and thickness. This process is often utilized in the manufacture of precision filter and other components.

Die Cutting

GMT’s in house die cutting operations speed production and enhance quality control. Our die cutting operation is capable of producing a finished piece with dimensions up to 33” x 48”.

Fusion Bonding/Laminating

GMT’s production facilities are capable of producing multi-layered materials through adhesive lamination or fusion bonding with a binder such as low-melt poly.

Texturizing

By needle punching a pattern into a metal wool or metal wool and poly blend material can improve a material’s performance and add strength. Texturizing is also useful to improve appearance or add a distinguishing characteristic to a material to create product differentiation.

Roll Coating

GMT’s roll coating capability allows us to add a functional coating to the surface of the material.
