Investment Casting of Dirt Bike Footpegs

Investment casting has long been a popular manufacturing technique for producing a wide range of metal parts with precise detail and excellent surface finishes. One such application that has benefited from this process is the production of dirt bike footpegs. These critical components not only enhance rider control and stability but also contribute to the bike’s overall aesthetic appeal.

Investment Casting Process

Investment casting, also known as lost-wax casting or precision casting, is a process used to create intricate and detailed metal parts. The process involves the following key steps:

  1. Creating a wax pattern: A wax pattern of the desired part, in this case, a dirt bike footpeg, is created. This can be done using injection molding, where molten wax is injected into a metal mold to produce the desired shape.
  2. Assembly: The wax patterns are then attached to a central wax sprue to form a casting tree.
  3. Investment: The wax tree is dipped into a ceramic slurry to create a ceramic shell around it. This shell is then allowed to dry and harden.
  4. Burnout: The ceramic shell is heated in a furnace to melt the wax and remove it, leaving a hollow cavity in the shape of the footpeg.
  5. Pouring: Molten 17-4 PH stainless steel is poured into the cavity, filling it completely.
  6. Cooling and solidification: The metal is allowed to cool and solidify within the ceramic mold.
  7. Shell removal: The ceramic shell is removed, revealing the solid metal footpeg.
  8. Finishing: The footpeg is separated from the sprue and undergoes various finishing processes, such as electropolishing and heat treatment, to achieve the desired surface finish and mechanical properties.

Material: 17-4 PH Stainless Steel

17-4 PH stainless steel is an ideal material for investment casting dirt bike footpegs due to its exceptional combination of strength, corrosion resistance, and toughness. It is a precipitation-hardening stainless steel, meaning that it gains its strength through heat treatment processes. This material is perfect for applications where high strength and excellent corrosion resistance are required, such as dirt bike footpegs, which are exposed to harsh outdoor conditions and constant wear.

Surface Finish: Electropolishing

Electropolishing is a process used to improve the surface finish and appearance of metal parts. During this process, the footpegs are submerged in an electrolytic bath and an electric current is applied. This results in the selective removal of material from the surface, creating a smooth, mirror-like finish. Electropolishing not only enhances the footpegs’ appearance but also increases their corrosion resistance and helps reduce friction between the footpeg and the rider’s boot, providing better grip and control.

Heat Treatment: Solution Treatment & Aging Treatment

To achieve a high tensile strength of 1,100 MPa, the dirt bike footpegs undergo a two-stage heat treatment process:

Solution treatment: The footpegs are heated to a specific temperature (around 1,900°F) and then rapidly cooled, typically by quenching in water or another suitable medium. This process dissolves any precipitates within the microstructure, resulting in a homogeneous austenitic phase.

Aging treatment: After solution treatment, the footpegs are reheated to a lower temperature (between 900°F and 1,150°F) and held at that temperature for a specified time. This allows the formation of precipitates within the microstructure, strengthening the material and improving its mechanical properties.

This combination of solution treatment and aging treatment enables the 17-4 PH stainless steel footpegs to achieve an impressive tensile strength of 1,100 MPa, making them highly durable and able to withstand the demanding conditions experienced during off-road riding.
