Heatshrink for wiring the extruder The Mendel extruder page talks about using heatshrink over the crimps that connect the nichrome wire. Looking at Maplin's site, all of the heatshrink products have "operating temperatures" far below the ~200C temperatures reached by the print head. Do this mean I need to look elsewhere, or, do the ends of the nichrome wire not reach as high a temperature as the "core"? In particular, I was interested in these combined heatshrink/crimp connectors. No operating temperatures quoted, but being PVC, I understand they'll be towards the lower end of the scale. Any comments? What heatshrink have others used? https://reprap.org/forum/read.php?151,47864,47864#msg-47864 Sat, 15 Aug 2026 17:23:52 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,47864,48746#msg-48746 Re: Heatshrink for wiring the extruder https://reprap.org/forum/read.php?151,47864,48746#msg-48746 Azdle General Mendel Topics Fri, 11 Jun 2010 14:45:11 -0400 https://reprap.org/forum/read.php?151,47864,47905#msg-47905 Re: Heatshrink for wiring the extruder https://reprap.org/forum/read.php?151,47864,47905#msg-47905 jcpren General Mendel Topics Tue, 08 Jun 2010 11:30:06 -0400 https://reprap.org/forum/read.php?151,47864,47874#msg-47874 Re: Heatshrink for wiring the extruder https://reprap.org/forum/read.php?151,47864,47874#msg-47874 shrinktubes from Raychem - they're specified until 250 centigrades ...]]> VDX General Mendel Topics Tue, 08 Jun 2010 08:30:10 -0400 https://reprap.org/forum/read.php?151,47864,47864#msg-47864 Heatshrink for wiring the extruder https://reprap.org/forum/read.php?151,47864,47864#msg-47864 Mendel extruder page talks about using heatshrink over the crimps that connect the nichrome wire.
