Producer: Athena
Founded in 1973 Athena is a group of 7 companies which produce gaskets, technical articles and metallic components for the industrial and motorcycle sectors.
They all operate according to the UNI EN ISO 9002 quality standards. Their main concepts are: reliability, availability, technical evolution and constant improvement.
Raw Materials
Athena is a Technolocical world leader in Head GAsket design and works with many of the performance OEM manufactures. Each Head Gasket configuration utilizes the best raw materials available, such as AISI 304 Stainless Steel. Athena utilizes state of the art processing such as in-line laser cutting and multi-stage stamping technologies. With our Multi-Layered Steel (MLS) Head Gasket, each layer is individually blanked and formed specially to optimize performance.
Optimized Embossing Formation
Through multi stage processing, our embossing process optimizes the radius in the bend areas. The result is reduction in stress points, improved conformability, and superior wet-out (contact area) that is superior to the competition. Our technology also provides a consistent inner flange spacing of (minimum of 0.040”) from the edge to the embossed start point. This results in a superior seal in the embossed areas.
Stress Stabilization & Relaxation
This proprietary tempering process significantly reduces forming induced stresses. Pre-coated metal (used by competition) would not be able to survive this stabilization process. Advantages of a tempered metal are reduced hardness and brittleness, increased flexibility and deformation retention. This process dramatically increases the long term durability and reliability of each head gasket.
Proprietary Coating Technologies
Four different layers are used to provide the ultimate seal between the head and block mating surfaces. These coatings will normally eliminate the need for additional
deck surfacing, Our coating processing provides 100% encapsulation of all exposed metal, far superior to the competition that has exposed raw steel on the edges. The layers include Fluoroelastomer (FKM) for extreme temperature and chemical resistance. This technology provides superior conformability, oxidation resistance, and better removability, even after extreme temperature exposure.
High Performance Cooper ring Insert
For specific very high horsepower applications, a conventional or MLS Head Gasket can be significantly improved utilizing a different sealing system for the combustion area. Athena utilizes a proprietary INOX steel fire ring which offers improved sealing technologies over copper and conventional fire rings. This solution dramatically increases the cylinder head gasket resistance.
FEM Test
FEM (Finite Element Method) allows our cylinder head gasket to be constructed and optimized before realizing their design and manufacturing. Our FEM software provides a wide range of simulation options for controlling the complexity of both modeling and analysis of the system.
1. Laser process:
State of the art laser allows high precision gasket cut from raw material. For specific reinforced materials in-house die cutting machines are used. |
 |
2. Embossing
Single gasket layers are embossed as per Athena specific drawing, in order to seal liquid and combustion gas. |
 |
3. Rivet assembling
Each head gasket layer is assembled and fixed with rivets, for perfect layer alignment. |
 |
4. Finishing
The application of different superficial coatings enables the gasket to better performance, prevent sticking phenomena and enhance high temperature resistance. |
