Powerblanket Hot Box and Curing Blankets for Post Curing

When it comes to post curing, maintaining ideal temperature is a must. And if you’re post curing small to medium sized parts, then you may find yourself using expensive ovens, or else taking a whole lot of time and money to build your own. Thankfully, you don’t need to do either of these with the Powerblanket Hot Box on hand.

Post Curing: Bring the Heat

Post curing is a process during mold making that consists of increasing heat to a mold after the initial curing phase. Doing so allows the mold to cure faster, as well as enhances the physical properties of the mold. During post curing, heat must be evenly transferred to the mold at a constant rate as to not interrupt the natural curing process and cause irreversible damage. These damages can cost time in redoing the mold and in money for having to use extra materials.

The best way to heat molds during the post curing phase is to use an insulated hot box. Hot boxes provide regular, even heating to materials that require protection from low or fluctuating temperatures.

The Powerblanket Hot Box

Powerblanket’s Hot Box (sometimes referred to as a Bulk Material Warmer) works great at maintaining the needed temperature for post curing small to medium sized parts. These insulated heating boxes provide an even spread of warmth to give the mold the exact increase of temperature desired.

The Hot Box’s durable construction allows for secure and lasting installation, while its ease of setup makes it transportable and storable. The Powerblanket Hot Box can be easily assembled, disassembled, and reassembled. It gives you the option of bringing your parts to the Hot Box or bringing the Hot Box to your parts. Our Hot Boxes hold product at a temperature of up to 120° F, and the optional adjustable thermostatic controllers allow temperatures to be controlled with precision.
So if you need to keep your epoxy cures at temperature for prolonged periods of time, a Powerblanket Hot Box just might be the thing for you.

Post Curing with Powerblanket Curing Blankets

Of course, after talking about the Hot Box, you may be thinking, “Yeah, but what if what I need to cure is bigger than 48” x 48?” Well, there are two simple answers to this question. Depending on your application needs, we could build a custom size Hot Box for you. But if one of our resin curing blankets would work better, we would certainly suggest this as an option.
