Rubber Extrusions – Sponge & Solid


Description

  • Ability to Produce the Most Intricate Profiles to RMA Class I & Class A Tolerances
  • Short and Long Runs
  • Secondary Operations

Over the years we have supplied a variety of extruded shapes to virtually every industry. At the same time our production capabilities extend far beyond basic extrusion processing. We have available the latest splicing equipment, high speed automatic cutting machines, and compression and injection molding presses which allow us to meet the most sophisticated end user requirements.

Zatkoff can provide both commodity and exotic polymers to most ASTM specifications or custom compound a material to provide the exact physical, mechanical and environmental qualities a specific application requires.

Our products are produced in a range of polymers, not limited to but including compounds from solid neoprene, nitrile, EPDM, silicone, Viton®, polyisoprene and SBR to closed cell sponge neoprene, EPDM, silicone, viton, CPE, and neoprene/EPDM blend.*

If you have need for a specific profile our staff can work from your prototype or part drawing to develop the tooling required and provide a detailed quotation on your requirements.

Secondary Manufacturing Procedures

Extruded shapes may be spliced, cut or punched to form endless or special shape gaskets as illustrated.

Application of pressure sensitive adhesive backings (PSA) also available.

Cutting / Notching

To facilitate the forming and installation of a complete gasket, (1) relief points, (2) notches, and (3) bolt holes may be located where required.

Extrusions can be cut to length.

Splicing

  • The Butt Splice is used for fabricating endless gaskets where there will be limited or no strain on the splice.
  • The Bevel Splice is an alternate to the butt splice and is used where the cross sectional area is insufficient toform a suitable bond by using the butt splice.
  • The Step Splice provides maximum bond strength permitting nominal deformation under compression ortension when used as a static seal.
  • The Corner Splice is used to form gaskets of special configurations. Spliced corners provide a satisfactorystatic seal where the splice is not under strain. Full Molded Corners with step splices away from the cornerare recommended where the gasket will be under strain.
  • Molded Splices – Many gaskets and ring seals may be produced economically by splicing extruded shapes toform complete gaskets.

Certain splicing molds are designed to produce straight splices while others produce a given radius or angle. A single mold will not make all types of splices.
