Electro-Mechanical Platform Use Honeycomb Stainless Steel Core

Electro-mechanical Platform Use Honeycomb Stainless Steel Core is mechanically welded to form a large platform with super flatness. It is made of thin, 50 mm wide stainless steel stripes building a thick honeycomb shaped grid. The Honey Comb is placed on top of the existing table grids. Electromechanical platform, plays the role of supporting, resisting pressure and reducing weight.

Properties

Welded honeycomb core, no matter what material is, such as aluminum, stainless steel, steel, titanium etc, possesses better mechanical properties against regularly produced glued honeycomb core. So it performs significantly better again the common honeycomb bonded by adhesive on strength, modulus, corrosion resistance, dimensional stability etc. However, generally, these critical performance variables should be evaluated: material, airflow and attenuation.

1. Material Composition

Stainless steel grade should be considered according to the real application. Custom materials other than stainless steel are available upon request. Here are the parameters need to be evaluated:

Durability

Material type and grade is the first aspect to be evaluated then plating, discussed in depth later, can improve durability.

Weight

Material, structure and thickness of the material can affect the total part weight.

2. Corrosion resistance

Typically brass and stainless steel should be used in slashing environments. Plating or nonconductive surface coatings can improve corrosion resistance for all honeycomb types.

3. Shielding Performance

Different honeycomb core material offerings have different electrical performance, due to both inherent base material properties as well as the differing manufacturing processes used during honeycomb forming. Therefore, different EMI shielding performance may be realized. Shielding performance for different materials is ranked as brass, aluminum, steel and stainless steel. Plating can improve honeycomb shielding.

Specific attenuation requirements can be met through either plated or unplated alloys. Plating adds cost to the final product vent. Plating process for improving shielding is ranked as nickel, tin, tin-lead and zinc.

4. Airflow & Attenuation

Airflow and attenuation are inversely proportional. Infinitely large honeycomb cells result in infinitely small attenuation (and vice versa). Typically, as a design baseline, airflow performance requirements are calculated to meet thermal performance needs for the assembly that the vent is to be installed onto. Once airflow is determined, attenuation and other requirements can be evaluated. Standard cell sizes for honeycomb are 1/16", 1/8" and 1/4", with 1/8" being most common. Standard thicknesses are 1/4," 1/2" and 1," with 1/4" being most common.
