Rubber Extrusions

The Engineered Products Division of Hutchinson Sealing Systems extrudes EPDM profiles for many Rubber Seal and Trim applications. With the ability to produce co-extruded EPDM profiles, we can offer our customers more options in their Product Design. We have the ability to reduce the density and produce dual density rubber extrusions with supported metal carriers as well.

 

Our vulcanized Rubber extrusions are used globally in a wide range of applications and markets, including:

- Rubber Seals

- Rubber Gaskets

- Military

- Automotive Rubber Seals

- Window Seals

- Railcars and Ships

- Automotive Trim

- Enclosure Seals

Our in-house, industry-leading material experts allow us the opportunity to custom blend compounds and match the ideal material properties to the application.

Our Rubber gaskets and seals can be produced with compounds that are resistant to:

- Heat/Cold

- Compression Set

- Wear

- Aging

- Friction

- Fatigue

- Abrasion

- Color Fade

Custom Gaskets and Extruded Rubber Seals

With the ability to assist in Customer Design Optimization, our engineers tailor solutions to your unique application or design criteria. Virtually limitless design and material options are at your disposal with our worldwide network of R & D Centers. Some of our unique innovative design solutions have been used in Automotive Rubber Seals, Window and door seals, Trunk/hood Gaskets, and Body side molding to name of few.

METAL CARRIERS

We use our cross head extrusion capability to extrude rubber over various types of metal carriers. This reinforces the extrusion giving it excellent retention properties. Some examples of metal carriers include:
    - Cold rolled steel (CRS) wire carrier
    - Cold rolled steel (CRS) wire carrier with melting warp (1.10" std. width)
    - Stainless Steel wire carrier (1.10" std width)*
    - Polypropylene co-extruded with TPV

And, we have some standard carriers which could reduce tooling cost and lead time

 

Specialty Coatings and Flock

Another innovative process we have to offer is Specialty Coatings and Flock application. Our ability to reduce friction between glass and window seals by using specialty coatings and flock is one of our specialties.

 

We offer:

Low Friction coatings (LFC) applied by Spray, Drip and Wipe. This helps with freeze release, durability, and as an installation aide.

Flock can be applied by electrostatic drop method or applied as a tape. Flock tape offers better aesthetics and consistency.

There are multiple methods to provide wear resistance on an extrusion:
    - PTFE - is Teflon based tape that is used as high temperature wear resistance surface.
    - Polypropylene (PP) strips- another component used in applications that require high wear
      resistance.
    - Reticulated Polyethylene (PE-R) - coextruded as a "dual durometer" process

ROLL FORMING AND RUBBER TO METAL BONDING

Roll forming is a continuous bending process by which coiled metal (typically steel, aluminum, or stainless steel) passes through custom shaped rolls. These rolls are mounted linearly, each carrying out a progressive bend in the metal. As many as 24 sets of unique rolls can be required to achieve a single customized profile.

Roll forming is an excellent method for rapidly producing parts in long lengths. Due to the upfront cost to produce the rolls and machine to mount them, roll forming is most cost effective on large volume profiles. It is most cost effective for large volume profiles. In some cases, we may have standard roll formed profiles reducing your tooling cost to zero.

Advantages of Roll forming are:

    - Lighter parts
    - Thinner walls then aluminum extrusions
    - Integrally stronger (work hardened)
    - Seamlessly integrates with Rubber extrusion by the use of a cross head
    - Parts can be made with a finish (i.e. Gloss, protective films, and more)
    - Enhances flange retention
    - Non adhesive bond

Rubber to metal bonding is utilized with roll forming to achieve superior part qualities. The ability to integrally bond rubber to metal by means of cross head extrusion allows for better seal designs, retention properties with metal carriers, and strength to weight ratios. Our material experts specially compound the rubber and treat the metal to promote adhesion. The bond is stronger than the tear strength of the rubber.
