I want to show you the different modes of operation for the Silver Bullet curing unit. The first is the pattern curing and it can be the white material which is for masters, the pink material you saw, or the Avatar material for casting. In this mode we have adjustments that can be made for the length of time of the pressure that's going to be on the pattern inside the mold prior to curing and then the length of time the lights are going to be on to cure. Now once we've determined a rough idea of what we want for like sized items, we can save the program in which case you can see that this is programmed number 2, 3 minutes of pressure time, two minutes and 45 seconds of curing time with the lights. If I wanted to change I simply scroll through, change any of the values that I would like to see, change the number I'd like, perhaps call this three or excuse me call this three, we can change this to three, enter and now save program.
In other modes of operation you can see that we can do standard silicone mold making that's at room temperature. This is generally an overnight cycle maybe the end of the workday. We've made a block of up to 20 individual molds that need to be cured in silicone and we're going to go into standard silicone mold making that's just a valuation of hours. So normally I would be running it probably 12 hours and I would start at the end of my workday and be ready by the time I came in. Again all the air would be automatically drained out and the molds be ready to cut.
Now there is another mode of operation for silicone mold making. That is rapid silicone mold making. That's going to use the heat generated from the lights to control the length of time that the mold is going to be cured in and reduce that time to about an hour and a half to two hours. So often it depends on what type of silicone I'm using as to how I'm going to set this. I may want to delay the heat coming on for 48 minutes but I certainly would want to change the mode here to about one hour. Excuse me we're going to change the mode to two hours, 0 minutes and I'm going to delay about 15 minutes of heat. So I've got two hours and nine minutes excuse me zero. Alright so now in rapid silicone mold making I'm going to be able to use heat from the lights to accelerate the curing of the silicone and I may want to delay that heat cycle depending on the silicone I use and how thoroughly it's mixed and what the temperature of it was. So in this case this is about standard for rapid mold curing. I'm going to wait 15 minutes before the lights come on to accelerate the curing but the complete cycle is going to be two hours. I'll mix up some silicone, put it on the top in after my molds have been filled put a little on the top of the chamber, and during the curing cycle I might touch it to see how how well the molds are carrying on the inside of the unit. So there you have the various mode operations of the Silver Bullet curing chamber. We have the HD pattern curing again for our duplication of master patterns or our patterns we're going to make for casting. Standard silicone mold making which is generally an overnight curing depending on the silicone you use and rapid silicone mold making which is adding heat from the lights to accelerate the curing to cure those molds in two hours or under.
