Introduction to hot runner heating coil
The hot runner heating coil is a kind of electric heating element. Because its shape determines its scope of use, there is no other electric heating element. The hot runner heating coil is generally used for hot runner plastic mold, blow molding machine, and extrusion. Exit the machine and the hot nozzle (spoon sleeve and nozzle). According to different sizes, the specifications of the hot runner heating coil are divided into many types, including hot runner heating coil 2.2*4.0, hot runner heating coil 3.0*3.0, hot runner heating coil 3.5*3.5, etc.
Hot runner heating coil features:
1, the maximum power density: 10W / cm2, standard power: 4W / cm2---6W / cm2
2, the outer surface has three processes of polishing, sandblasting and blackening.
3, can be equipped with K-type, J-type, E-type temperature-controlled thermocouple.
4, high temperature power cord can choose 200 ° C PTFE line, 300 ° C PTFE line, fiberglass copper line, glass fiber nickel line.
5, high temperature casing can choose stainless steel woven mesh, fiberglass casing (HSM1-B4), waterproof casing (HSM1-B5), metal hose (HSM1-B3), linen casing (HSM1-B1), high temperature plastic Hose (HSM1-B2)
6, stainless steel 304 material maximum temperature temperature is 750 ° C
7, can produce straight or winding finished products.
8, hot runner heating coil has a circular section and a square section and a flat section of various forms, 2.2x4.2mm,3x3mm,3.5x2.7mm,3.5x3.5mm and so on.
