Fiber orientation.
Dear All,
Hope you all are doing well !!
Actually, I have a doubt regarding Fiber orientation. I am using PBT GF30% material.
Apart from changing Gate location is there any other way to change the fiber orientation?
Please do needful !!
Thanks and regards,
Mandar.

Re: Fiber orientation.
Fiber orientation can be affected by shear which is going to be controlled by injection speed and part thickness. I will assume you cant change part thickness either so to get more orientation you will need to fill faster, to get less orientation you will fill slower.

Re: Fiber orientation.
Only speed can save you. Or try with gb material if it is possible. I had a problem because the part was visible and on my luck customer was satisfyed with gb material. Or try with some mineral fibres...

Re: Fiber orientation.
Mold temperature can influence this as well. Hotter mold will slow the resin skinning up allowing the fiber orientation to change somewhat.
