PROCESS PRODUCTIVE OF CUT RING SEALS

1. FLATTENING PROCESS Each gasket is flattened to reach the optimal flatness, according to the required tolerances.

2. SILICONE EDGING An edge is applied during processing silicone on critical areas of the gasket, to increase the seal around the water and oil passages.

3. FINISH The application of different treatments to the surface Allows the seal to have a better seal performance, prevents any adhesion phenomenon and ensures resistance to high temperatures.

SEALS MULTILAMELLAR (code 338 > ) MLS Athena gaskets are designed to offer a superior hold, thanks to the wide choice of thicknesses and edges on oil and water passages with respect to the product OEM. The seals are made of layers of stainless steel first quality and high elastic memory (2 to 5 layers). For the sealing of the combustion gases on the cylinder bore comes used a folded sheet metal technology. In the end, a special coating applied to the surfaces of the gasket ensures tightness against small imperfections.

CHARACTERISTICS

– Designed specifically to respond to pressures in the cylinder and increasingly higher temperatures (le Athena multi-lamellar seals are installed by many car manufacturers as original equipment).

– Produced in AISI 301 stainless steel with high elastic memory (full hard material).

– Equipped with a combination of 3 to 5 slats internal and external, they are suitable to resist levels higher compression rates than the configurations standard. The steel grades used for the slats can vary depending on the needs of the engine.

– Provide excellent holding power throughout surface evenly, to compensate for any type of cylinder bore distortion.

– They are the best solution for both engines with in aluminum and cast iron block, both for engines with aluminum head and aluminum monobloc.

– Each slat is cut with a cutting edge laser generation that guarantees perfect quality of the cut while the reliefs are printed with a optimal stabilization process.

GAS STOPPER Gas Stopper technology is a key factor in design of multilamellar gaskets. The stainless steel blade is folded on itself around the cylinder hole ensuring a perfect seal even at high pressures. The Gas Stopper works around the combustion chamber to allow the cylinder head and engine block to tighten up even more tightly and thus prevent gas outlets.

BENEFITS

– High sealing properties under high conditions compression;

– Greater elasticity and constant load resistance;

– Optimized load balancing;

– Better engine performance;

– Greater durability over time.

BENDING RADIUS OPTIMIZED The survey formation process is a unique system which optimizes the radius of curvature in order to increase stability in critical areas. In particular:

– Increases the conformability of the gasket reducing stress points;

– Improves the grip of the contact area of ​​the pads between the engine block and the surface of the cylinder heads.

TREATMENT THERMAL OF RELAXATION All head gasket lamellas are subjected to a relaxation process to significantly reduce the tension induced during the carrying out of the surveys. Unlike others, Athena pre-coated metals endure this type of treatment perfectly.

The main benefits are:

– Reduction of hardness and fragility;

– Greater flexibility and resistance to deformation;

– Relieving tension points after the process survey formation;

– Stabilization of the seal which allows a stress reduction in the cylinder bore;

– Increased combustion tightness around the cylinder (relief profile) to withstand high pressures.

TECHNOLOGY OF COVERING EXCLUSIVE The coating on both sides of the outer slats comes applied after the stress relief process, to ensure uniform coverage and thus avoid any type of it breaking. This process, which occurs in two phases, ensures excellent sealing against refrigerant fluids and engine oils and responds to any needs you may have can occur in different hostile environments.

– The first layer of the coating is resistant to high temperatures temperatures and allows you to reduce temperatures to a minimum irregularities in the surface of the engine block and the cylinder head;

– The second layer is a silicone-based compound which prevents the gasket from sticking during installation disassembly of the engine.

SEALS MLS - MLS PRODUCTION PROCESS

1. LASER PROCESS A cutting-edge laser allows high cutting definition of the gasket. For specific materials reinforced internal machinery is used die cutting.

2. RELIEF MOLDING Every single slat is worked to obtain the formation of reliefs according to the technical drawing by Athena which ensures tightness against liquids and gases combustion.

3. RIVET ASSEMBLY Each individual slat is assembled and fixed with of the rivets to ensure optimal alignment of the layers.

4. FINISH The application of different treatments to the surface Allows the seal to have a better seal performance preventing any phenomenon of adhesion and ensuring resistance to high temperatures temperatures.

FEM TEST - The FEM (Finite Element Method) test allows you to create a wide range of simulation options for control the complexity of both modeling and system analysis, displaying stiffness and strength. The FEM test also allows a detailed view of the points where structures bend or distort and indicates the distribution of stress and displacement centers.

GENERAL NOTES BY INSTALLATION - ATTENTION: When preparing the engine, keep in mind that the diameter of the gasket must be larger than to the bore. In particular, the diameter of the gasket it must be +0.5 to +1mm wider than the bore. For example if the bore measures 86mm, it is recommended to use a gasket with a diameter of 86.5mm to 87mm. This it is a general indication which in any case does not replace the opinion of your trainer.

INSTALLATION PHASES

1. Thoroughly clean and degrease the engine block and the contact surfaces of the cylinder head.

2. Check the flatness and finish of the surfaces contact. TO GET A GOOD SEAL IS A LOT IT IS IMPORTANT TO RESPECT THE ABOVE SPECIFICATIONS. If the contact surfaces exceed the indicated tolerances, the head height or cylinder head must be rectified by a qualified mechanic. Excessive processing will have consequences on the compression ratio, on the piston clearance / valve and camshaft timing in engines with overhead camshaft. For this reason they must observe the engine manufacturer's restrictions regarding to the thickness of the cylinder head.

3. Remove traces of dirt, oil and corrosion from the holes of the bolts present in the block. IT IS IMPORTANT THAT THESE THREADS ARE CLEAN, OTHERWISE YOU WON'T GET THE CORRECT TIGHTENING, WHICH WILL CONSEQUENTLY RESULT IN A SEAL MALFUNCTION.

4. Lightly lubricate cylinder head screws/bolts e tighten them completely by hand by inserting them into the engine block. Using a steel ruler, measure the height of the screw bolt protruding from the block. All measurements should have the same length (unless screws are used bolts of different lengths). A longer length it may mean that the threads are not clean. Inspect the threads and clean again if necessary, so as to equal the lengths of all studs/bolts. IF THIS OPERATION IS NOT CARRIED OUT, THE MATCHING OF THE SCREW/BOLT THREADS DOES NOT IT WILL BE CORRECTED AND THIS MAY RESULT DAMAGE TO BLOCK DURING TIGHTENING OR TO ENGINE WORKING. After checking the inserted length, remove screws/ bolts and clean them.

5. Check that the sealing surfaces and threads are clean, dry, free from debris/smudges and have no visible marks sharp edges. If cylinder head screws are used, they must be mounted according to the manufacturer's instructions. Center the racing gasket on the block making sure not to scratch its coating.

6. Gently lower the cylinder head onto the block, making sure that debris does not fall onto the gasket and that its coating does not get scratched.

7. Fit the nuts/bolts following the manufacturer's instructions. Pay attention to the lubrication instructions provided as well as well as torques and tightening sequences. OTHERWISE, IT WOULD PREVENT THE SCREW / BOLT TO ACHIEVE FULL PRELOAD, CAUSING A MALFUNCTION OF THE GASKET. WE ALWAYS RECOMMEND THE USE OF NEW BOLTS AT EVERY HEAD DISASSEMBLY/ASSEMBLY.

8. Reassemble all other components, top up engine oil and refrigeration systems. Check that there are no leaks and, if so, check the cause. 

9. Start the engine and wait for it to reach temperature of use. Check for leaks. Then, stop the engine, let it cool down and check the cause.

10. If no leaks are found, after the heating phase, you may need to retighten the screws/bolts of the cylinder head. Consult the manufacturer's instructions.

TECHNICAL SPECIFICATIONS

The sealing surfaces must not have scratches, scratches, localized corrosion or cracks, as these can cause a loss. For finishing sealing surfaces to be rectified, respect the following maximum values: Rz 11μm -  Rmax 15μm - Wt 8 -10μm . The values ​​can be measured with a finishing probe superficial like a “Mitutoyo Surftest” roughness tester. The Ra values ​​given below are almost equivalent to the values previous ones and are obtained with Rottler type machines, Robbi, Serdi, etc.: Ra 0.8 μm for vertical processing (with cutting tips). Ra 1.6 μm for surface grinding. These values ​​refer to use on finished surfaces comparable to that produced by Flexbar.

MAXIMUM DEFORMATION VALUES Using a level rule and feeler gauges, the distance maximum in the longitudinal direction is: For a length of 100 mm, maximum 0.03 mm -  For a length of 400 mm, maximum 0.05 mm - The maximum distance in the transverse direction for a length of 100 mm is 0.03 mm. IN GENERAL, IT IS BETTER TO TRY TO GET FLATTER SEALING SURFACES POSSIBLE, FOR ENSURE MAXIMUM TIGHTNESS OF THE RACING SEAL. NB: codes starting with 338 refer to the gaskets MLS, those starting with 330 Cut Ring seals.
