Rubber Gaskets and Seals.
Rubber gaskets and seals are vital components used in a multitude of applications to prevent seepage of moisture or air. Qualiform is the source for custom manufactured rubber gaskets and rubber seals. No matter what application, Qualiform has the experience to solve a variety of sealing problems. We provide a comprehensive line of commercial and specification grade elastomers to fabricate a variety of rubber parts including:
- Rubber Gaskets
- Rubber Seals
- Rubber Washers
Qualiform has the resources to assist you in developing new designs and selecting materials and processes. Qualiform's technical staff considers many factors in the design process and recommend the best method to meet our customers' quality and cost requirements. For large or small runs, our manufacturing capabilities mean a prompt response to your sealing needs.
There are two separate stages in the life of a gasket or seal:
- Its primary fit and function.
- Its ability to endure its environment.
Qualiform knowledgeable staff considers such factors in the design stage of rubber gaskets, so they will not be the weakest link among all components in a product. Environmental factors to consider in gasket or seal application are:
- Flammability - UL specifications, heat resistance
- Function - the motion acting upon it
- Impermeability - exposure to gases
- Organic materials - fungus resistance, odor, tastelessness
- Temperature extremes - heat, cold
- Weather - water, ozone, sunlight
Seal types
Static Rubber Seals
Where there is little or no motion of assembly parts on the seal.
An initial compression or intervallic compression (open and close) characterizes this type of seal:
- A liquid seal in a hose joint
- A door seal on a home
With use of a Static Seal, compression pressure operates in a vertical direction relative to the face of an O-ring or face gasket and constricts two different surfaces to eliminate gaps.
Dynamic Rubber Seals
Where there is repetitive motion of assembly parts on the seal.
Repeated actions on the seal, recurrent or intermittent, characterizes this type of seal:
- A shock absorption device
- A piston ring seal
Dynamic Seals are more complex than static seals because of the varying stress levels. In addition to Static Seal considerations, Qualiform engineers assess abrasion resistance because it is affected by the companion surface finishes. Other considerations include: compression set, temperature changes, thermal cycling, distortion, recovery speed after compression, physical strength, tensile strength and tear resistance. Qualiform engineers asses all of these environmental forces and provide the most efficient and cost effective methods to meet our customers' quality and cost requirements.
Qualiform Custom Rubber Molding creates quality custom rubber compression molding, custom transfer molding, custom rubber injection molding and rubber to metal bonding with the highest standards in customer service.
