Our Best-Selling Other Machined Parts
Aluminum Casting Parts for Bike
Aluminum casting parts refer to components manufactured through the aluminum casting process, where molten aluminum is poured into a mold and allowed to solidify, producing complex and accurate shapes. These parts find widespread applications across industries such as aerospace, automotive, electronics, and more, due to their lightweight, excellent thermal conductivity, and remarkable corrosion resistance.
Aluminium Die Casting And CNC Machining Parts
Aluminium Die Casting is a process where molten aluminum is injected into a mold under high pressure, resulting in intricate and complex shapes. CNC Machining, on the other hand, involves using computer-controlled machines to remove material from a workpiece, producing highly precise and custom-made parts. With CNC technology, we can create CNC milled parts, CNC turned parts, CNC milled parts, stamped parts, deep-drawn parts, injection molded parts, rapid prototyping, as well as cast and forged components.
Laser Cutting Part
Laser Cutting Parts refer to components that are created using the laser cutting process. Laser cutting is a highly precise manufacturing technique that utilizes a concentrated beam of light, or laser, to cut through various materials with great accuracy. It's an advanced method that has found its way into numerous industries due to its versatility and precision.

Advantages of Aluminum Casting Parts for Bike
Reduced weight:
Aluminum is a light material, which minimizes the weight of the bicycle, something crucial for both racing and mountain biking.
Corrosion Resistant:
Aluminum is Corrosion Resistant because it will not rust over time. The special layer of oxide on the surface prevents it from being damaged by the environment.
Somewhere between steel and plastic:
While it has less strength than steel in many ways, aluminum weighs less and can be easily molded.
Environmentally friendly:
An environmentally friendly way to buy drinks is to choose aluminum, since it can be recycled multiple times.
Production Process of Aluminum Casting Parts for Bike
Making the Mold
A special steel mold is created by using the blueprint of the part being manufactured. We do a quick clean and apply lubricant to the mold for every run.
Heating Aluminum to Melt
Ingot aluminum is heated to a temperature of about 660°C (1220°F) in a furnace. To make aluminum consistent, the melted aluminum is maintained at a constant temperature.
Filling the Mold
The molten aluminum is pushed, using very high pressure, into the mold cavity by a cold chamber die casting machine. Because of this pressure, the metal takes on all the right shapes inside the mold.
Cooling and Setting
Within a few seconds, the aluminum hardens and solidifies inside the die. Proper cooling is necessary to minimize flaws in parts and improve their strength.
The Part is ejected from the body
As soon as the metal is totally solid, the mold is opened, and the formed part is ejected. Part makers can release the item safely with the help of ejection pins.
The next steps are trimming and finishing
Any surplus plastic waste (such as flash or runners) is cut off. To achieve better performance and appearance, the required treatments for the part can include machining, polishing, surface treatment, or painting.
Monitoring and Checking Quality
Every part is checked for defects such as open spots, cracks, and irregularities. It is important in quality assurance that everything produced only reaches the end phase or shipment if it meets exact specifications.
