Austin Allen 250 PRT Injection Moulder
If I remember rightly it has a shot capacity of 12gm.
It needs 1kw single phase (240vac) for the heater and electrics. @80psi, air consumption is 7.8cfm for a 10 second cycle, but on single shots you can get by with a 4cfm compressor (just). On auto the cycle time can be adjusted from 3-50 seconds.
The lock pressure is 7.5 tons @ 100psi and 9 tons @ 120psi
Maximum mould (billet size) 7.5" x 8" x 4" (x2 as they are mould halves) the mould can then open upto 4" for part ejection.
Machine foot print 32" x 15" and it's 66" tall, can be broken down into two or more parts for transport. I got it home in an estate vehicle, the machine is over 200kgs in total weight.
I don't have any pellets left as they are long gone, last used with nylon some years back. I am looking for £600 ono, buyer collect I'm afraid from South Yorkshire, it has the original operating and service manual.
Any further questions please just ask.

I used to have several moulding machines - small ones made by Austin-Allen and were single phase. OK for small parts. I sold the machines many years ago but now find that I need some moulding made using the tooling I made for the Austin-Allen machines.
If there is anyone out there who has any Austin-Allen machines and would like to make a few bob doing some moulding, please get in touch. I can promise you will be glad you did.
Cheers
