How To Make a Small Engine Cylinder

We have prepared a slideshow demonstration of How To Make a Small Engine Cylinder.

Today we are at the Hyway manufacturing facility where we engineer and manufacture aftermarket small engine parts for outdoor power equipment. We specialize in Nikasil cylinders for small engines.

Nikasil is short for Nickel Silicon Carbide plating. Harder than steel, Silicon Carbide (a very hard ceramic) is dissolved in nickel and then electroplated onto the cylinder bore. This is the process used by Formula One race car engine cylinders. They undergo extreme usage, so you know it’s a process that is good for small engines. A Nikasil plated cylinder has much better heat conductivity and engine tolerances can be set much tighter for better performance. These cylinders are also much more durable and do not have to be re-worked nearly as often.

9 Steps: How To Make a Small Engine Cylinder

  1. The core is placed into the middle of the mould.
  2. The molten alumninum is poured into the mould all around that core.
  3. Let the small engine cylinder cool and solidify.
  4. Remove from the mould (still hot).
  5. Get the sandy core out of all the hollow places.
  6. CNC the holes.
  7. Bore out the core.
  8. Electroplate with Nikasil.
  9. Inspect the newly made small engine cylinder for perfection.
