Show and Tell / Re: Styrofoam blocks?
December 13, 2013, 07:53:28 AM
$750 for a single block sounds high.

We keep a rather comprehensive list here:

The closest I see on there are Grenada, MS and Houston, TX which are both quite a distance.

For 1lb foam in Iowa where I'm located it's available for under $200, and 2lb foam for a little over $300 plus shipping. Sometimes there are higher prices for 1 qty, and price breaks for higher quantities that are worth asking your block molder about. Also the prices do fluctuate with petroleum prices as Polystyrene is made from a combination of Ethylene and Benzene which are petroleum based products.

Hi Mooremetal,

We usually let our customers decide for themselves if buying our equipment is a good business decision since there are a lot of factors in running a successful business including geographic location and personal know how and connections to the market.

I can only suggest you do your homework and be comfortable with it. If you decide to go ahead, we sell great machines that can help you be productive and I hope we would get your business.

Hi Hector,

There is not a simple answer I can give you on the forum.

Styropoxy / Re: Spraying Styropoxy

We advise against thinning the Styropoxy and I have not tried this. I'm not saying you can't try it, but our formulary technicians say it's not a good idea.
Styropoxy / Re: Spraying Styropoxy

Hi Imageres,

Even though we have not found a great way to spray large quantities of the Styropoxy 7015 and 7060 at this time, it is spray-able with a gel coat gun found here:


The 3/16" I/D opening is perfect for the Styropoxy as it's very thick. You also need to hold the gun pointed to the ceiling if you are not actively trying to spray as the material can drip out the large orifice otherwise.

The thing is from tests it was producing the most smooth molds when you brush after spraying. Two coats (brushed each time) produced the finest results.

So for some users the spraying becomes redundant and only makes more clean up than needed. For others it is a good way to apply it. I'll leave that call up to the users.

In tests with other gravity feed HVLP guns it was possible to spray, but it applied the material so slowly it may aggravate the user and test their patience.

One sure way to apply it is to mix and pour evenly across the foam then spread with brush. I typically use the disposable brushes, but it will clean up with Acetone, Alcohol, or warm soapy water if you want to reuse your brushes.

Show and Tell / 8300 Extreme Tapers Video
February 17, 2011, 08:55:14 AM

Here's a rough little video of the 8300 doing a very steep tapered cut in high density (2lb) foam.


The ability to move each end of the machine is one nice thing about the 8300 because it allows for 16'+ monolithic cuts as well as these tight little tapers that aren't possible on fixed towers.
