My first injection mold and the Rabit HY-4 injection molder

[gavztheouch]

Hi John,

Nice to see another Rabit 2/3 owner on the forum. I have not made any progress on the mold or machines yet. A machine did come up for sale on ebay a couple of months and I managed to ask the owner some questions on the design of the molds. I shall look out that original email and post it here.

Hi back at ya!

I am taking my Rabit 2/3 apart at the moment and have gotten down to where the injector housing appears to be attached to the main cast body of the machine. It isn't that obvious how it comes apart now. I suspect I have to undo the five 2 or 2.5mm (need to get these hex keys) and then the whole turned heater assembly looks like it will simply slide out the front of the frame.

It looks like it won't be amazingly difficult to increase the capacity of the shot from the original 2 grams. I am hoping to get it up to 8 grams so it will cover a wide range of parts that I hope to reproduce for my business which is restoring arcade (and pinball) games. I expect there will be modifications to the machine, but I'm hoping that will mostly be software/hardware to increase the melt time and the impulse time to allow the increased amount of plastic to squeeze in and set prior to release.

I take it the original manufacturer doesn't have anything left on these machines, not being in the UK it is a bit hard to nip around to their shop and see, but the web site suggests they (Mining & Chemical Products Ltd - MCP Group SA - http://www.bloomberg.com/research/st...capId=27830480 - 1-4 Nielson Road Finedon Road Industrial Estate Wellingborough, NN8 4PE United Kingdom). are now just into geological stuff since being bought out by 5Nplus. Their web site mcp-products.com is broken...
