I'm working on a project for a client and it's my first injection moulding project, it's a cattle reader similar to: http://livestock.tru-test.com/sites/default/files/TTSM-829955-EID-XRS2-STICK-READER-INTL-ScanAdv-%28F%29-942x220_0.jpg
Client is on a tight budget as it's the first product. I wondered if anyone had any clues as to what we might be looking at in terms of tooling costs for one cavity and also for two, if the upper and lower parts are to be different? I can appreciate it's a difficult one to answer. The design might lend itself quite well to a symmetrical, modular casing, reducing the need for two cavities, but design for this would require quite some consideration...
Initial production run is only for 300 units, so would an aluminium tool reduce costs? What about CNC machining parts from solid? May not be so cost prohibitive for low volumes?
Any advice would be greatly received!
