Title: CNC Mold Machining Available
Post by: camcutprecision on 03/01/18 08:12 UTC
Good morning,
I have started a new CNC machining business specializing in small mold, die components, prototypes and production run components. I was thining making some custom molds for baits might be needed and sure enough, it looks like it is. From hand sketch, we can create a machinable CAD model of the bait, and the mold for customer approval. Once approved, CNC machine the mold, and send out. If any additional info or quote required, please contact camcutprecision@yahoo.ca.
Thanks
Ryan

Spin Cast molds aren't made of aluminum, they're made of rubber.

The cost of a spin cast mold depends on the diameter of the mold.

If you can fit 20 of your lures on a 12" wheel then expect around $250 or so for a spin cast mold.

In addition to this information, spin casting equipment is generally used for casting lead or tin or other molten metals. I'm thinking that if your plans are to make plastic baits you'll end up with one heck of a mess.

Without a doubt.  Large commercial plastics molds are made of aluminum and they're not cheap.  I knew a guy that had a 50 cavity made and it was north of $5k.

Interesting.  I've never seen that before.  It seems one could inject them in about the same time.

Well that's different but cost-wise a guy had better have one heck of a market to pay for the plates and the motor. My spincaster had a considerably smaller pour hole and the plates were inside an enclosure. I had the option of aluminum plates or the discs made of silicone and silicone molds were still very costly, aluminum was out of sight expensive.

That's not a traditional spin cast machine.  The pressure to hold the silicone mold parts together is done by air pressure.  The mold sits on one plate and the other comes down on top.

Mine machine used fulcrum clamps to hold the 2 silicone mold halves between the plates. No air whatever was used.
