Venho informar-vos que em breve irei desactivar o presente blog. Aquilo que nasceu de uma brincadeira, para comemorar o Campeonato Nacional dos juniores, tornou-se, num veículo de informação do nosso Clube.

Todavia, o CDPA merece um projecto melhor, mais completo, e actualizado com maior frequência.

Uma última palavra para os vários redactores, que aqui actualizavam a Vossa informação: obrigado.

D: Business Ideology

Our success in these industries can be attributed to the investment casting process which is ideally used where;

  • close casting tolerances are required,
  • intricate and complex shapes are cast reducing or, in some cases, negating the need for machining
  • where superior finishes are required, particularly in the use of carbon steel
  • due to high costs or difficult to machine alloys, machining should be avoided or minimized
  • changes in material specification due to prototyping or sampling may be required
  • good strength to weight ratios are required for example where thin sections are to be cast in light alloys

repeat orders or batch delivery is required investment casting is ideal due to low tooling costs and the longevity of the wax injection dies, the result is shorter turn-around times and an ultimate cost saving.


E: Sales Fields

So far we have lots worldwide customers, including Japan, Taiwan, and China...etc

Now YF Industry is looking for global partnership

We hope we can provide you the best quality with high accuracy and competitive price, so we can create a win-win situation for both sides
