E-bike Motor Mount Solution

The E-bike motor mount is part of the E-bike frame. In the past, the commonly used process for producing parts such as E-bike motor mounting plate and hanger is forging. Compared with aluminum alloy forging process, aluminum liquid forging(aluminum squeeze casting) has the advantages of high production efficiency, reducing processing volume, reducing cost, and producing parts with more complex structure. Using aluminum squeeze casting to produce an E-bike motor hanger will be the trend in the future. At present, Komman air suspension manufacturer has provided E-bike motor mount hangers for many international E-bike manufacturers. If you have interest, please contact us, we can provide a sample for free.

Aluminum Squeeze Casting E-bike Motor Mount Advantages

High production efficiency
  • The traditional forging process to produce ebike motor mount plates and hangers with complex structures requires complex procedures and requires a lot of post-processing. It may need to be forged for more than 3 times to form, and the production efficiency is low. However, the aluminum alloy liquid die forging process can be formed at one time. The machining allowance is small, and the efficiency is high.

Better product appearance
  • Obviously, the E-bike motor mount hanger produced by aluminum squeeze casting process has a better appearance because there is no weld seam.

Good mechanical properties
  • Generally speaking, the mechanical properties of parts produced by forging process are the best. However, for parts such as E-bike motor mounting plate produced by forging process, due to the existence of forging streamline, the metal properties show anisotropy. However, the parts produced by aluminum squeeze casting have no forging streamline, and the mechanical properties are close to forging, which can fully meet the needs of customers.

Lower cost
  • Traditional forging process to produce E-bike motor mount hangers may need to forge for more than 3 times to form, a lot of post-processing is required. However, aluminum squeeze casting process can reduce the cost by 40% - 60% compared with traditional forging because of its simple air ride suspension custom process and less machining allowance.

Introduction Of Aluminum Squeeze Casting

Liquid forging, namely squeeze casting, also known as melt forging in Japan, is a method to apply large mechanical pressure (about 100MPa) to the liquid or semi-solid metal entering the mold cavity to form and solidify it to obtain castings.Due to the simultaneous existence of high-pressure solidification and plastic deformation, the casting has dense structure, no defects such as porosity and porosity, and fine grain. T6 heat treatment can be carried out. Its mechanical properties are significantly higher than ordinary castings and close to the forging level of the same alloy. It is an excellent process to realize lightweight.
