Feature
● Four-Side Far Infrared Heating with Centrifugal Fan Circulation
Far infrared heating tubes are installed on all four sides of the heating chamber (top, bottom, left, right), heating the product simultaneously from every direction rather than from a single heat source. A high-speed centrifugal fan continuously circulates the heated air to stir and equalise temperature throughout the chamber. This four-side, fan-assisted heating design is specifically suited to thermal radiation heat shrink tubing used in new energy vehicle wire harness assemblies, where radiant heat absorption characteristics differ from conventional heat shrink materials.
● Constant Temperature Control — No Deformation or Discolouration
By distributing heat evenly across the chamber rather than concentrating it at a single heating element, the EW-19O maintains a constant temperature throughout the heating zone. This prevents the localised overheating that causes heat shrink tubing to deform, discolour, or shrink unevenly — a common defect on single-source heating equipment where the side of the product closest to the heat source receives disproportionately more thermal energy than the opposite side.
● High-Temperature Teflon Mesh Conveyor for Continuous Production
Products move through the heating chamber on a Teflon mesh conveyor belt rated to 350°C, enabling continuous assembly-line-style processing rather than batch loading and unloading. Conveyor speed is adjustable from 0 to 6m/min, allowing dwell time in the heating zone to be matched to the specific heat shrink tubing material and wall thickness being processed.
● Floor-Standing or Desktop Configuration — Production Line Integration
The machine is available as either a floor-standing or desktop unit; the desktop configuration can be relocated as needed and synchronised with an existing production line's control system for inline integration. The welded frame structure allows the heating chamber dimensions to be customised to match specific product size requirements beyond the standard configuration.
● Intelligent Control with Adjustable Temperature and Speed
Heating temperature (0–260°C) and conveyor speed (0–6m/min) are both independently adjustable through the intelligent control system, allowing the machine to adapt to the specific temperature and dwell-time requirements of different heat shrink tubing materials and product geometries without mechanical reconfiguration.
Application Range
New energy vehicle (EV/NEV) wire harness heat shrink curing
New energy vehicle wire harnesses increasingly use thermal radiation heat shrink tubing, which requires the specific four-side far infrared heating and constant-temperature environment the EW-19O provides to shrink correctly without deformation. This makes the EW-19O particularly suited to EV battery harness, motor cable, and high-voltage wiring assemblies where heat shrink insulation and sealing performance directly affects electrical safety.
Large or irregular-shaped harness assembly curing
Wire harness assemblies with multiple branches, connectors, or irregular geometries that cannot be processed through a single-point heat gun or single-head shrink machine benefit from the EW-19O's tunnel format, where the entire assembled product passes through the heated chamber and receives even heat exposure regardless of its shape complexity.
High-volume continuous production lines
Production lines requiring inline heat shrink curing as one step in a continuous assembly process — rather than a batch operation requiring manual loading/unloading at a separate station — use the EW-19O's conveyor belt format to integrate heat shrink curing directly into the production flow at the line's takt speed.
Heat-sensitive component curing requiring deformation-free results
Products where heat shrink tubing must maintain precise dimensional tolerance and surface finish after curing — connector boots, sealed junction points, and cosmetic-grade harness sections — benefit from the EW-19O's constant-temperature, four-side heating approach, which avoids the surface marking and dimensional distortion that single-source heating methods can produce.
