热流道弹簧管

主要以GRNI钢作外壳材料，用强力压缩氧化镁、进口发热丝，发热管制成后，给回火处理，可结成各种形状，充分加

热接触面积最有效的传导工作温度可升到700℃(1300°F)。可选择内置式热电隅（J型、K型、E型）主要应用于热流道模具、

吹塑机、挤出机及热嘴(浇道套和喷嘴)。It mainly employs GRNI steel as sheathing material, adopting the high compression magnesia and imported heating wire, after the heating pipe

is well manufactured, carry out tempering treatment, it can be formed into many shapes, fully heat up, make the most effective conduction, the

working temperature can be as high as 700℃(1300°F). The built-in thermocouple (type J, K and E) is selectable, it can be mainly applied to hot

runner mold, blow molding machine, extruding machine and hot spout (sprue bush and nozzle).
