BP6 Low Temperature M6 Heating Block + Throat Hotend Kit For 1.75mm 0.4mm J-head Extruder Lerdge Board

Introductions: 1. The heating block and radiator are made of high-purity aviation aluminum. The anodized surface is with a matte texture. 2. High-purity stainless steel material is provided on the throat tube. The unique thick-walled design with the same diameter and the rib design makes it easier to install. 3. The nozzle is made of high-quality international brass that produced by high-precision machining. The chamfering design allows the inner wall to be smooth, and the contact surface flat. The outlet hole of the filament is in the center avoids unsmooth threading and plugging. The laser engraving specifications of each nozzle make it more convenient to recognize. The quality can be saved from the details. 4. Custom non-threaded quick coupling makes the product looks more beautiful. 5. Low-temperature module: can the feeding tube from internal directly to the nozzle throat (that is, the feeding tube completely through the throat) directly to the material sent to melt effectively prevent plug the nozzle, suitable for below 250 degrees material used. For example PLA, ABS, HIPS, etc. About the color changed after some time use of the heating blocks: Due to technology limited, the anodized metal surface color is only for appearance use. After the use of aluminum block, the color will change because the color dye on the metal surface will get evaporated during the high-temperature heating, including the natural aluminum block, just not that obvious. (For example, a black frosted heating block will turn yellow when it is heated at a high temperature). But it will not affect the use at all. It is not a quality problem. If you mind this, please consider before you decide to buy it. Package List: (Low temperature module containing ) 1 x 0.4mm Nozzle 1 x Aluminum heating block 1 x Throat
