Hopefully someone reading this works with injection moulding machines daily and can off load some knowledge.

I brought a 25ton old injection moulding machine impulse but i have been looking for a while. And i have parts i need made that are currently being cnc from stock sheet.

Krauss Maffei Mono-Mat 25

"This machine has a 27mm screw and 60mm stroke. It should give a shot weight approx. 40gms in ps governed by molding area and wall thickness."-seller

It was cheap i think? $700USD + freight $800USD

Some initial questions. ( more to come)

Aluminium moulds will be used as part runs will be small, sub 1000 /year. Can i buy mould blanks with core pins and bushings pre machined? and just have cavities machined.

Insert moulding dies how do they work where can i get them? i have a few different parts i want to run so maybe this is the best way.

How big a part can i make from a nylon 6 maybe a filled nylon? 2-3in2?

What do i need to look out for when setting up initially?

that will do for now.

thanks in advance
