Injection moulding pressure power (polypropylene)

Good day to everyone!

Currently I’m working with recycling Polypropylene, and I have a few products that I want to produce with the injection machine. Since it’s a semi-manual machine I’m quite curious how high the pressure of injection material in to a mould could be. This is quite important information cause it’s critical for the size and thickness of the product.
If someone has experience with working with polypropylene in the injection machine (size, thickness, viscosity) I would love to know.

Thanks for reading and I would love to hear from you guys!
