300W Copper Hot Runner Coil Heater Stainless Steel 220V One Year Warranty
220v 300w injection molding machine nozzle heater hot runner coil copper heater
Description:
1) A thin layer of the "high" thermal conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, "low" thermal conductivity layer backs up the element wire, directing the heat inward toward the heated part. The result is more efficient heat transfer—a performance solution lowering element wire temperatures and increasing heater life.
2) Nozzle heaters are hermetically sealed for liquid plastic during the manufacturing process. The connection between the heating element and the leads is protected by a special fitting made of brass/stainless steel 1 mm thick, without welding which allows a high mechanical strength in the most delicate area of the heater.
