ALUMINUM EXPLAINED: PRODUCTION METHODS WILL NOT AFFECT STIFFNESS
How can we increase the stiffness of wheels? As long as wheels are made of aluminum alloy, using a different production method does not affect the stiffness of the wheel. That’s because all aluminum alloys used for forging and casting create same material property with identical stiffness.

You may think forging process creates stronger materials. However, when forged and cast aluminum alloys are measured by the Young’s modulus, it shows almost no difference between two methods. Forged and casted aluminum alloys are nearly identical in specific gravity as well. Therefore, if you make an exact same shape of wheels using forging and casting method, the weight of those wheels should be the same. What is the advantage of the forging process, then? It is an ability to produce higher material strength.

Generally speaking, compared with casting, forged material is superior in yield strength and tensile strength. However, no matter how great the material strength, it cannot justify an extreme reduction in weight.

Even with adequate material strength, if wheels lack stiffness, they cannot perform properly even with high-performance tires.

Durville Die Casting & MAT Process
Enkei has adopted two technologies – the Durville die casting and MAT process that ensure cast aluminum wheels have strength comparable to forged ones. In the Durville process, molten aluminum alloy is poured into the mold from its inner rim side, with the disc side facing downward. The alloy is rapidly quenched and solidifies, starting at the disc side, creating a finer metallic structure, significantly enhancing tensile strength, yield strength and elongation.

In the MAT process, the wheel rim placed on a mandrel is spun and rolled. This spinning process creates “metal flow” in the metal structure of the aluminum alloy, which is similar to the metal property seen in the forging process.

This hybrid process of casting and forging gives wheel high material strength while keep manufacturing cost more affordable than forged wheels. Additionally, it gives greater freedom of design on the wheel face.

Design Capability behind the best wheels

How does Enkei ensure its wheels have high stiffness? The answer is Enkei’s “Design Capability”.

To maintain high stiffness under great force, the wheel’s cross sectional area in the direction against the force applied needs to be enlarged. Unfortunately, the larger this area is, the heavier the wheel will get. However, if the layout, cross sectional shape of the spokes and the rim profile are designed properly, the wheel can maintain high stiffness without
adding weight.

The layout is made possible by Enkei’s vast accumulation of wheel design data and the computer aided engineering 3D simulation. In addition, Enkei strives for the largest possible weight reduction by identifying the wheel portions where stress concentration is least likely to occur and shaving down areas that do not affect stiffness.

Enkei’s processing techniques ensure the “strength” of its wheels, and its excellent design capability ensures “stiffness” and “lightness.” Enkei’s design capability is the most-treasured asset and essential for developing the highest performance wheels.

Great for pore reduction
Color: Cyano Pink Spicule
This product works great!! it almost feels like an exfoliator. It reduced the pours on my nose, which were very big and now you can barely see them. I would recommend this product if you have large pores also make skin look firmer and smoother more for a night cream though.

More than expected
Color: Cyano Pink Spicule
Love, love and recommended to friends. Leaves my skin feeling and looking great. At 69 I don't expect miracles but can definitely see an improvement in texture, glow and line minimizing. I'm hooked and will never be without!

Micro-needling effect!
Color: Cyano Pink Spicule
Love how you can feel the micro-needling effect. I use this is my first application after toning and follow up with my serum and moisturizing routine. I do believe it gives my face a plump feeling, especially after gua sha. Will continue to use in my daily!

Helps my moisturizer absorb better
Color: Cyano Pink Spicule
I’m not quite sure if the product is fully working the way it is supposed to but I do like that when I use this and the apply moisturizer, it absorbs into my skin better and leaves my skin smoother and a lot less greasy. It’s easy to throw in my travel bag because of the size and you really only just need a little for each use so it goes a long way got the cost.

Amazing!
Color: Cyano Pink Spicule
This makes my skin feel so smooth. The appearance of my skin also is starting to look a lot better/younger. I've been using it for a week and a half already seeing changes.
