Where Do You Buy A Hot Plate Without All The OSHA Safety Cr*p?

I am getting ready to try out a new 6 cavity mold and need a electric hot plate to pre-warm the mold. All the hot plates on the Internet I find now have a safety device that turns them on and off at 190F! Is this warm enough to pre-heat properly? I sure am glad our government is helping to keep us from scalding ourselves with boiling water since we have dumbed down since childhood.

I just set them on top of the furnace.

I use hot plates in my home made smoker. I just take them apart and bypass the auto-shut thingy.

In 25 years of casting I have never used a hot plate. Aluminum moulds preheat quickly on top of the furnace.

Try Wally World, Walgreens or Harbor Freight. I got mine at Walgreens, heats my 6 cavity up real nice.

Agreed--I got mine at Wal-mart. The hot plate warms the mould up much better than setting it on top of the furnace.

Also, once I got my mould up to temp I turn the heat down on the hot plate and use it to pre-heat my ingots before I put them in the pot.

I use this one:http://www.amazon.com/Maxi-Matic-ESB...4119010&sr=8-1

and it gets plenty hot.

Main reason I like it is that it has a solid plate top made of cast iron instead of the heating coil. Heating is much more even than the coil burner type.

I don't cast, but I can tell you the cast iron plate will glow dull red on high which should suffice for your needs.

When I was casting I used a blow torch with a duckbill spreader on it.

Something's wrong there. That won't even boil water (212°F). You must have found some kind of warmer rather than a hot plate, at least, not a hot plate the way I use the term.

I looked at reviews at the Wal-Mart and Amazon web sites and many complained that the hot plates did indeed cycle on and off all the time and would not even boil water. Maybe just poor construction from China!

Then they're warmers. Don't know what else to call them. I took a quick look and noticed one brand seemed to be everywhere. That may be the problem. The factory could have tried a conversion from °C to °F and got it backward.

furnace, Noun - an enclosed chamber in which heat is produced to heat buildings, destroy refuse, smelt or refine ores, etc.

For casting bullets they tend to look like this.



Hope that helps.

Found mine at the local Big Lots for $12. Heard they shut off a bit early so I took out the switch and filed off the stop a bit. Melts wheelweights in a little iron skillet well enough, but not ideal.

The heater for my casting machine is about as anti OSHA as you can get. It is just a 3500 watt 230vac oven element wrapped around a pipe. I use a solidstate relay and PID to control temp but if you just plug one in they will keep going up in temp until they melt.

You have to forgive Dave he is from Florida, they don’t know what a furnace is down there.

You just need one with higher wattage. This one at Wally World will definitely boil water.


And living in Houston, where we average 2 days a year below 32 degrees..... what the heck is a furnace?
