Hello guys.

I want to buy a machine that assemble mist pump spray or pump spray.i don't need a production line and i need a machine or tool that can assemble components of a pump spray manually or by human not automotional. i do some research and i realize that a pneumatic press or a manual_hand press can help me in this project. but many of them are out there.

i need to help to find what pressure and velocity is sufficient for my work and how can i get that? by a book?by an equation? ....

and if you have another suggestion for my project, i will be very happy.
besides, i attach a PDF of my project and some dimensions of my pump spray.
Thank you so much.
