    How does the clamping cylinder and ejector work on this 2 platen machine?

    Thanks! That is the most sensible and logical information I have received so far. Is there a separate low-pressure feed to the clamp directional valve? So the 3 hoses that go into the ejector side of the cylinder, 2 of which are ejector advance and retract, the 3rd is nothing to do with the...

    How does the clamping cylinder and ejector work on this 2 platen machine?

    As my previous post. I am trying to work out how a recently acquired 1982 Arburg 220-90-350 works so that I can 1. get to know how it works and 2. build a new control system. For a few reasons, 1 so I can know the machine inside out, 2 so I can have loads of practice in PLC programming and...

    Information required on an old Arburg 220-90-350

    I have recently acquired a 1982 Arburg 220-90-350 injection moulding machine, mainly just as a hobby to further my knowledge on injection moulding machines and control systems as I plan to design my own control system for it using an HMI as the user interface. The machine and control cabinet...

    Steel Building top floor supported by rafters

    Totally with you and that's the plan, I just like to be as fully informed as possible when talking to someone, as well as knowing why things are being done the way they are. I like this option very much which is probably what I will go with subject to proper calculations etc. Like I said I...

    Steel Building top floor supported by rafters

    Thanks again for your input, The truss design as suggested BAretired would limit the floor space far too much, the upper floor is to house an assembly line which requires the entire length of the building. I can't see why any additional bracing would be required on portal 2 as the inner...

    Steel Building top floor supported by rafters

    Thanks for all of your responses, it's good to know the idea is do-able. The initial design does have wall and roof bracing, eaves beams and ties at the top of the hangers, I just supplied a simplified drawing for clarity. I'm more in the process of feasibility and budgeting at the moment...

    Steel Building top floor supported by rafters

    Just to make it clear that I am not going to start building anything without consulting a structural engineer first, I just wanted to make sure I'm not off my nut for suggesting it and that the idea is at least feasible. I am a qualified and experienced welder and fabricator and have built and...
