DESIGNED FOR YOUR APPLICATION
Hot Runner Manifold Heater
Hot Runner Manifold Heater manufactured by LICHENGDA with custom voltage, wattage, dimensions, materials and termination options for industrial applications.
ENGINEERING GUIDANCE
Specify this product correctly
Engineered to distribute heat across injection-molding manifolds while avoiding cold spots around flow channels. Heater routing, sensor placement and zone control should be reviewed from the manifold drawing.
Final voltage, wattage, dimensions, material and termination are reviewed against your operating conditions before production.
- ✓ Drawing, sample or application-based development
- ✓ Prototype and low-volume production support
- ✓ Integrated heater, sensor and termination design
- ✓ OEM and ODM production for global equipment makers

PRODUCT ENGINEERING
Manifold channels and heating-zone balance
Hot Runner Manifold Heater: Use the manifold drawing to define grooves, cold sections, terminal exits and heater retention. Distribute the active path around flow channels and mechanical openings to reduce avoidable cold spots.
Review sensor locations and independent zone control together with the formed heater. Confirm groove tolerances and contact pressure before selecting the final electrical loading.
For Hot Runner Manifold Heater, request the missing voltage, power and finished dimensions before calculating current, selecting a supply or fixing the mounting pattern.
For Hot Runner Manifold Heater, send the supply, continuous and peak temperature, mounting drawing, lead exit and quantity. Include the heated medium and control method so the quoted configuration can be checked against the actual duty.
Application and reference configuration
Hot-runner manifolds and injection-molding systems. The final suitability of Hot Runner Manifold Heater depends on the assembled equipment and agreed operating conditions.

ARCHIVED PRODUCT INFORMATION
Description
This type is special shaped bent tubular heaters for hot runner manifolds, the core heating components of hot runner systems for injection molds, available in round tube and square tube types.
1. Left Right Structure Difference
Left: Round Tube Heaters
Made of round tubes with specified diameters of 6.6 mm and 8 mm. Custom bent shapes can be made according to the hole sizes of manifolds for direct installation into drilled holes in manifolds.
Right: Square Tube Heaters
Made of square tubes with cross section sizes of 6×6 mm and 8×8 mm. Square tubes provide larger contact areas with molds, delivering higher heat transfer efficiency and more uniform temperature, making them widely used in high end hot runner systems.
Product Features
Manufactured via one piece bending forming, custom complex shapes (U shaped, Z shaped, Y shaped, multi loop designs) are available to perfectly fit hot runner manifolds with complicated structures.
Terminal pins extend from both ends for connection to temperature controlled power supplies, enabling precise mold temperature regulation.
3. Material & Application
Sheath material: Typically 304 / 310S stainless steel, high temperature resistant and oxidation resistant, suitable for high temperature injection molding environments.
Main purpose: Heating injection mold hot runner manifolds to keep plastic melt thermostatically molten, ensuring stable molding for multi cavity molds. Widely applied in automotive parts, home appliances and precision plastic molds.
4. Key Advantages
Compared with round tubes, square tubes feature larger contact areas, more uniform heating and lower heat loss, ideal for high precision, multi cavity molds. Round tubes offer strong versatility and easy installation for conventional molds.
Product Description
Hot runner coil heaters are made of nickel chrome resistance wire placed inside chrome nickel steel tube filled with MgO powder and compacted for faster and efficient heat transfer. The heaters are annealed to acquire malleability for bending into any shape. Hot runner heaters with built in thermocouple are also available. Hot runner bushes are produced with hot runner heaters of different cross section with inner brass and outer stainless steel cover.
