Extrusion lines and line marking machines move molten or highly viscous material from the melt source to the die, nozzle or applicator. A rigid pipe cannot follow moving heads, and an unheated flexible line lets the material cool, thicken and block. JINGCHENG's Extruder Heated Hose is an electrically heated flexible connection for this job: it carries the material between machine sections, keeps it hot along the entire length, and is rated for a maximum service temperature of up to 250°C, withstanding a pressure of 35 MPa at 250°C. The hose is in long-term, stable supply to a number of well-known domestic extruder manufacturers.
Material transfer on extruders and marking machines puts heat, pressure and movement on the same line:
Material freezing: polymer melts, hot melts and marking materials solidify quickly when they lose heat
Viscosity drift: a temperature drop along the line raises viscosity and causes uneven output at the die or nozzle
High pressure at high temperature: extrusion pressure must be carried while the line is at full working temperature
Movement and vibration: moving heads and vibrating machine frames need a flexible line rather than a rigid pipe
An extruder heated hose solves these together: it is flexible, pressure rated and actively heated.
The heating layer consists of uniformly braided heating elements. Because the heat is spread evenly around and along the hose, temperature differences on the inner wall are minimized and the material leaves the hose at a consistent temperature.
High-insulation-efficiency materials surround the heating layer. They are selected with the outer surface temperature in mind, which reduces heat loss and makes the line safer to work around.
Each hose can be fitted with the sensor your controller uses (Type J or Type K thermocouple, Ni120, PT100 or PT1000), and with the connector and pin layout of your machine, so the hose is controlled as one more heating zone of the extruder.

The Extruder Heated Hose is suitable for the flexible material connection on all common types of extrusion equipment, extruders and line marking machines on the market. Typical uses include:
Extruders: heated melt connection between the melt pump, filter and die
Extrusion equipment: flexible heated transfer between machine modules
Line marking machines: heated delivery of marking material from the melter to the applicator
Machine builders: OEM heated connection hoses built to the machine's electrical and fitting standard

JINGCHENG heated hoses are identified by a model code such as JCH-200-16-B-3X220-P2-8:
200: working temperature in °C (200 = 200°C)
16: hose inner diameter in mm (16 = Φ16)
B: inner tube material (B = stainless steel corrugated tube; TB = PTFE hose with stainless steel braid; T = PTFE hose; X = special material)
3X220: working voltage (220 = 220 V; 3X220 = three-phase four-wire 220 V)
P2: temperature sensor (P2 = PT100 two-wire; P3 = PT100 three-wire; K = Type K thermocouple; J = Type J thermocouple; W = no sensor; T = special sensor)
8: working pressure in MPa (8 = 8 MPa)
Ambient temperature: -40°C to +55°C
Relative humidity: not more than 85%
Atmospheric pressure: 86 kPa to 106 kPa
Voltage range: 12 Vac to 380 Vac
The surrounding medium should not contain gases that corrode metal or damage insulation, or conductive media, and severe mold must not be present. For special environments, contact us for a customized hose.
Wire the hose according to its technical parameters and the pin table supplied with it.
Do not twist the hose sideways during or after installation; lateral twisting can cause leakage, flow loss, hose damage or fire.
Avoid sharp bends; bending the hose too tightly can damage it and cause short circuit, leakage or fire.
The hose should be operated only by authorized and trained personnel, ideally the same dedicated operators.
Unauthorized modification or adjustment of the hose voids the warranty.
If you meet a problem not covered by the instructions, contact us so that our engineers can guide the installation.
