HW-R612 Rail Oven

The HW-R612 is a six-zone rail-type SMT reflow oven from China SMT machine manufacturer HWGC, built to reflow solder paste on PCB pads with forced hot-air convection. Six upper and six lower heating zones span a 2,100 mm heating tunnel, followed by two forced-air cooling zones, while the stainless steel Z-shaped mesh belt and rail carry boards at 0-600 mm/min. RKC PID controllers with fuzzy logic and SSR output hold ±1°C accuracy, and the 24 kW startup power brings the oven from room temperature to a stable profile in about 15 minutes, making it a practical workhorse for lead-free and leaded PCB assembly.

Key Features

• Efficient heating system with long-life Swedish nickel-chromium heating wire and curved reflectors for fast heat-up and high thermal efficiency
• Forced hot-air circulation structure heats the PCB and components evenly across the 2,100 mm heating tunnel
• High-density rock wool insulation rated at 120 kg per cubic meter, suitable for both leaded and lead-free soldering
• Taiwan long-shaft high-temperature air motors with loop-type heating wire in a modular layout: low noise, low vibration and easy maintenance
• Perforated galvanized air-distribution plates above and below the boards deliver balanced heat to the PCB; the upper oven body opens fully for chamber cleaning
• Taiwan STK speed-regulating conveyor motor with a 1:60 worm reducer for smooth stepless transport accurate to ±20 mm/min
• RKC precision temperature controllers with PID intelligent calculation and fuzzy control to suppress overshoot and respond quickly to heat changes
• Taiwan Fanda thermocouples in every zone plus SSR solid-state relays with dedicated heat sinks for contactless, reliable switching
• Over-temperature alarm, fault diagnosis, audible-visual warning and delayed shutdown protection for uniform cooling

SMT Industry News

AI server boards and other high-end computing PCBs are driving strong demand for SMT capacity and high-precision placement equipment, and the reflow stage has to keep pace with the boards feeding into it. Those assemblies often combine fine-pitch parts, large copper areas and tight thermal budgets, so a compact six-zone oven with ±1°C control, a 2,100 mm heating tunnel and steady forced-air cooling gives smaller factories a repeatable lead-free profile without a large footprint. Smart factory integration is spreading across SMT production lines at the same time: the HW-R612's full computer PID closed-loop control, fault diagnosis and alarm records make it straightforward to connect oven performance with the line-level data systems that Industry 4.0 projects expect.

Applications

The HW-R612 suits small and medium PCB assembly lines that need a dependable SMT reflow oven with a short footprint, including consumer electronics, LED drivers, power supplies, industrial control boards and prototyping runs. Its rail and mesh-belt transport handles both bare boards and framed panels, and the 40 mm component clearance accepts taller parts on mixed-technology assemblies. For electronics manufacturers upgrading from manual or bench-top soldering, it is an accessible lead-free soldering platform from a China SMT machine manufacturer that also supplies the rest of the SMT production line.
