KingFar heavy duty suction cups achieved this with relative ease by using medical grade plastic that made it easy and safe to handle by any person. This meant that the product had to deal with temperature variations without losing its adsorption capability. Another major breakthrough was that it could be used in countries which had severe winters. So what was this result? A product that could fall under the category of wreath suction hook as soon as it rolled of the manufacturing line. They revamped their strategy and started experimentation with different techniques and materials to achieve the desired result. KingFar realized that old manufacturing methods will not help it in meeting demands in this category. KingFar- A market leader that leads by example This is not easy to do and requires changes in design and materials without compromising the basic principle of adsorption as the main method of attachment and detachment. In order to do this, they need to replicate the functionality and strength of the products they are replacing. They are meant to replace the traditional permanent hangers that people use on their windows, doors and walls. They can bear extremely strong loads and are used for specific situations. Strong heavy duty suction cup hooks are named that for a reason.

The cups will not slide or fall off when it adsorb vertically.Kingfar Suction Cups Solutions – The seal of cups are good, and no air release from the gapģ.

The diameter will not changed when pull the cups.Ģ. This calculation method should meet the following conditions:ġ. Also, according to the international standard, the safety factor of suction cups should be ≥2, so the suction should also divide this safety degree.Īll in all, a 100 mm diameter suction cups should hold a weight ≤27.47 KG. But as the vacuum degree cannot never reach 100%，generally it will be counted as 70%, then the suction should be: F=78.5*0.7=54.95 KG. So, in theory, the biggest suction force will be 78.5 KG. Generally means the Atmospheric Pressure.įor example, If a diameter of sucker is 100 mm(10 cm),and the surface area that sucker can covered is 78.5 c㎡. S:The surface area that sucker covered（c㎡）

Suction of Suction cups: The force that separate the sucker from the surface of the adsorbing object. Once the suction cup falls off, serious consequences will be caused. As they are big suction cups, the mounted or adsorbed objects are very large or bulky. It is very important to check the airtightness before using the suction cups.Especially the industrial suction cups and heavy duty suction cup hooks.It is also necessary to confirm whether the weight of the adsorbed objects exceeds the adsorption capacity(safety factor must be ≥2). Since it cannot penetrate the surface of the sucker, it forces it to hold the sucker firmly to the surface.If the suction cup surface or edge is damaged and external air enters the suction cup, the suction cup will not work properly and will fall off. As the atmospheric pressure are always trying to keep its equilibrium, this pressure push the external air.

Once squeeze the air out, it will turn into vacuum. When we use it, we need to force to press the sucker on the flat and smooth surface. The bottom of caps has a concave down area. The airtightness of material between Rubber and silicone suction cups are both good.
