What manufacturing techniques are used for bicycle pedals?

1. Forging: Forging is a metalworking process that involves shaping metal by hammering or pressing it. Forged pedals are strong and durable, making them ideal for high-performance cycling.

2. Casting: Casting is a manufacturing process that involves pouring molten metal into a mold and allowing it to cool and solidify. Cast pedals are typically less expensive than forged pedals, but they may not be as strong or durable.

3. Injection Molding: Injection molding is a manufacturing process that involves injecting molten plastic into a mold and allowing it to cool and solidify. Plastic pedals are lightweight and durable, making them a popular choice for recreational cycling.

4. CNC Machining: CNC machining is a computer-controlled manufacturing process that involves using a cutting tool to remove material from a workpiece. CNC-machined pedals are typically made of metal and are known for their precision and durability.

5. Stamping: Stamping is a manufacturing process that involves cutting and shaping metal by using a stamping press. Stamped pedals are typically made of thin metal and are often used on low-cost bicycles.

6. Welding: Welding is a metalworking process that involves joining two or more pieces of metal by heating them and fusing them together. Welded pedals are typically made of metal and are known for their strength and durability.

Additional Finishes: In addition to the manufacturing techniques listed above, bicycle pedals may also undergo various finishing processes, such as anodizing, plating, or powder coating, to improve their appearance and durability.
