I need to make a piece "synchrokörper" made from GFK plastic

Could any one tell me what kind of plastic it is?

I am not sure of the plastic type, but it may be that this abbreviation stands for Glass Filled Ketone.

Anyway it might be worth contacting this company for advice (they may have a website)

ERTA n.v.
Industriepark "NOORD"

Tel 32 51 42 32 11
Fax 32 51 42 33 00

Telex 81800

I think they are based in Belgium or Holland.

GFK stands for Glass reinforced plastic ( in the German language )and most of the time people use this abbreviation for epoxy or polyester with glassfibres ( or glasscloth )

GFK stands for glass fibre reinforced plastics.
For injection molding it's used as an additve for engineering plastics (nylon, ABS, POM, PP, etc.)
The additive is between 5 and 50% of the volume.
It's makes the plastic very strong, sometimes higher percentages are stronger than steel.
Disadvantage of GFK is molds and tools wear away very fast.

Hi all , thanks all you for the helful post.
Since my post , I had visited the on site machinne and I saw that the plastic has glass fiber web or mesh all its volumen.
Up to day I can not know what plastic could it be.
The only particular tip is that it is coloured soft transparent green.
Unfortunly this machine works a 7 day week , 24 hours day, so I can not take a piece for analysis it.
Others thing I get, is that it shall resist a solution of Sodiun Nitrate 15 % in water , neutralized to Ph 7 with Nitric acid.
This piece is used at an electrolitic deburring machine.
Here in my country we can not import such spare parts from the original vendor , so we need to make this pieces local.
Our plastic vendor could supply me whit ACETAL RESIN ,
NYLON OR TEFLON.
We thougt that ERTAACETAL C could suit this porpouse.

Thanks in advance
