Ludo Injection Moulded Pistons

What is it?

This is a very good simple injection moulding device that has been superseded by the Ludo Mk2 Injection Moulded Pistons device. The Ludo Mk2 Injection Moulded Pistons device can use recycled plastic and not only HDPE pellets like the above design.

Good Things

  • Makes pistons to very accurate dimensions
  • Low cost to make
  • Simple to use and repair
  • Ludo Engineering can produce the moulds on mail order
  • Relatively low cost
  • Can be replicated out of mild steel in a simple local workshops

Bad Things

  • Only new HDPE pellets can be used as the supply material unlike the Ludo Mk2 Injection Moulded Pistons
  • Needs expensive oxy-acetylene  gas to heat
  • Moulds must be made on a lathe which are generally only available in large cities
