After a sunny and relaxing summer break our batteries are charged and we are ready for some action!
TPC WEBSITE
The new website have now been published for more than a year. There are still some services upcoming, so look out for it.
WELCOME!
We welcome all the new recruits to our ranks! Some of which have been active for a while now and a couple that are on the way to join us. We look forward to a productive future together!

Investment Casting Process

  • Produce wax patterns and wax feeder system
  • Build a ceramic shell in multiple layers around the wax structure
  • Melt the wax out from the ceramic shell
  • Burn and preheat the hollow ceramic shell
  • Pour liquid metal into the hot ceramic shell
  • Break the shell and cut the finished casting from the feeder system
Investment Casting General Advantages
  • Wax is a material easy to shape
  • Geometrical freedom of design
  • Geometrical freedom allows complex feeding systems
  • Alloy contracts (shrinks) 8% from liquidus to room temperature
  • Hot shells allow smooth as cast surface quality Ra 2 – 5 µ
  • Hot shells allow thin sections to be filled
  • Process repeats close tolerances from 0,08
  • Shell can withstand high temperatures
  • Shell does not influence casting during contraction
  • Shell does not react with alloy
  • Open system allows influence on cooling rates after casting
  • Superalloys are not suitable for forging, welding or other cold forming methods
