Paraffin wax is solid at room temperature and only flows while it is kept hot. In a wax 3D printer, any cold section in the feed line lets the wax thicken or set, the flow to the printing unit becomes irregular and the line can block completely. JINGCHENG's Paraffin Wax Hose, also known as the 3D printer wax hose, is an electrically heated hose built to keep molten wax liquid on its way through 3D printing equipment. It is heat resistant up to 230°C, and it has been upgraded generation after generation together with our customers' printer models and technology, so it matches 3D printers closely and its quality is now very stable.
The line that carries molten wax inside a 3D printer has a direct effect on print quality and uptime:
Solidification: wax that cools below its melting range sets inside the hose and blocks the line
Viscosity changes: partly cooled wax thickens, so the volume delivered to the printing unit no longer matches the program
Cold spots: a single unheated section near a fitting or a bend is enough to start a blockage
Downtime: clearing a hose full of set wax stops the machine and wastes material
An electrically heated wax hose keeps the wax at a controlled temperature along the full length of the line, so it reaches the printing unit as a free-flowing liquid.
The heating layer is made of uniformly braided heating elements wrapped around the inner hose. Heat is spread evenly over the inner wall, which keeps the temperature difference along the hose to a minimum and leaves no cold section where wax can start to set.
High-insulation-efficiency materials surround the heating layer. They are selected with the hose surface temperature in mind, so the heat stays in the wax, less energy is lost and the outside of the hose is safer to touch inside the printer enclosure.
3D printing is a young and fast-moving industry. As our customers have released new printer models and upgraded their technology, the JINGCHENG wax hose has been updated with them, which is why it fits 3D printing equipment closely and runs with stable quality.
A temperature sensor (Type J or Type K thermocouple, Ni120, PT100 or PT1000) can be built into the hose so the printer's controller can hold the wax line at its set point.

The Paraffin Wax Hose is used wherever molten wax has to stay liquid between two points of a machine:
Wax 3D printers: heated wax feed lines inside 3D printing equipment
Paraffin wax transfer: short heated lines that keep paraffin liquid between the melting unit and the point of use
Printer upgrades and new models: hoses built to the connection, length and sensor layout of each printer generation
Replacement hoses: heated wax lines made to match the electrical and fitting layout of an existing machine

Every JINGCHENG electrically heated hose is built to order. The catalog order form lets you specify each of the following:
Item | Catalog options |
|---|---|
Rated voltage | 380 Vac, 220 Vac, 110 Vac, 12 Vdc, or other |
Temperature sensor | Type J thermocouple, Type K thermocouple, Ni120, PT100, PT1000, or other |
Hose length | 3 m, 4.5 m, 5 m, 6 m, 10 m, or other |
Inner diameter | Φ8, Φ12, Φ16, Φ19, Φ25 mm, or other |
Hose working pressure | 4 MPa, 10 MPa, 20 MPa, 35 MPa, or other |
Rated power | 110 W/m, 150 W/m, 170 W/m, 200 W/m, or other |
End fittings (each end) | US, British or metric thread, or other |
Wiring | Pin number, wire color and function defined for the controller end and the gun/tool end |
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.
Inquiry: send us your requirements by phone, fax or the inquiry form.
Specification confirmation: our engineers propose the most suitable specification as a quotation reference.
Quotation: we issue a quotation; you confirm with a purchase order.
Production: the hose is built in our factory to the confirmed specification.
Inspection and packing: every hose is checked for defects and packed.
Shipment: the hose is shipped to your designated address.
Wax and temperature: tell us the wax you use and the temperature the line must hold (standard heat resistance up to 230°C).
Size and length: choose the inner diameter for your wax flow (seven catalog sizes from 1/4" to 1") and the length needed inside the printer.
Electrical: specify the supply voltage (380 Vac, 220 Vac, 110 Vac or 12 Vdc), the power per meter and the sensor type your printer controller reads.
Connections: give the thread standard at each end (US, British or metric) and the connector and pin layout.
Routing: plan the path inside the machine so the hose is not twisted or bent sharply, especially next to the fittings.
