DIY Ceramic HeatCore. So much easier then trying to wrap nichrome wire around the heater barrel and then tape it in place. Once you’ve assembled your HeatCore just screw it on, attach your hook-up wires and power up. Makes disassembling, cleaning and rebuilding your plastruder much quicker, easier and consistent!

Each kit includes enough material to make two HeatCores.

M6 HeatCore Kit contents:

-(2) 3/8" Brass Cores – threaded M6
-(3) 300mm pieces of Nichrome Wire - one piece is an extra
-(2) 1/5 oz. containers of Ceramic Adhesive (Cotronics Resbond) and Popsicle stick applicators
-Hook-up Wires
-Molex Connectors and Crimp pins < New
-Crimp Pins for attaching Nichrome to Hook-up wires
-M6 Screw (mount)

New M8 HeatCore Kit The same as the M6 HeatCore Kit except the Brass Cores are slightly larger and threaded M8.

You will need a soldering iron and solder for attaching the crimp pins and nichrome.

Fully Assembled HeatCores are available in the Enhanced Operators Pack.

Assembly Instructions

Thermal fuses are used in devices like coffee makers. If the device temp exceeds the rated value on the thermal fuse, the fuse breaks and cuts power to the device. We are not currently using thermal fuses with the HeatCores but we’d like to build fuses into a future release. Maybe you can figure out how to do this! If you do, please post your results!!

Power Resistor Heater Kit

This kit is based on Nophead's design and contains:

-(2) Vishay wirewound, 6.8Ohm, 6W, 5% resistors
-(2) Aluminum blocks 0.5" x 0.75" x ~20mm
-(1) Cotronics Duralco Thermally Conductive Epoxy (to attach the resistor to the aluminum block - rated for continuous service up to 500C)
-PTFE sleeves (for resistor leads)
-PTFE coated wire (to attach to resistor leads)
-(2) Male & Female Molex connectors with crimps (to connect resistor to hook-up wires)
-(2) Wood applicator for epoxy

You'll need to drill the the hole for the power resistor and drill and tap the hole for your heater barrel.

Note: We have tested these in-house but we are not currently using them in our products or to heat our plastruders.
