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
I'd ask the seller what the actual ounce size is of the barrel. I'm assuming around 1.5 oz. But it'd be better to know for knowledge
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.
You can buy a mold base, which has the leader pins and return pins in them. You have to have core pins made when the cavities are 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.
If your parts aren't very big, I'd go with a MUD frame from DME. All you have to do is change out the mold (as it's in a frame). Here's a link to what I'm talking about https://na.dmecompany.com/Catalog/Ca...ilId=327&NSM=Y

How big a part can i make from a nylon 6 maybe a filled nylon? 2-3in2?
It really goes by weight, or cubic inches of material.
What do i need to look out for when setting up initially?
Take it slow and read as much as you can on setting it up and running the parts.
that will do for now.
thanks in advance
