The manufacturing process of pistons has changed considerably
since the inception of the internal combustion motor. Modern
piston manufacturing is fully automated with little or no human
intervention. This is not the case with JP Pistons. JP Pistons
strength lies in our ability to manufacture very low numbers of
pistons at a time (for example, 10-20). This ability means that
we do not, and cannot, compete with the massive automated
facilities of the manufacturers of mass produced pistons for
modern vehicles. It also means that they cannot do what we do
either. What is laid out below is the way that we make pistons.
We use many modern manufacturing processes, but also older
methodologies which ensures our position as a niche
manufacturer. NOTE: The images here are all available in larger

piston. At the foundry the die is prepared by heating it to
operating temperature for approximately one hour. This process
allows the die to readily accept the molten m
