HUAQIZHENGBANG High-Efficiency Reflow Soldering Machine

It uses a hot-air (hot-wind) heating method with 8 heating zones (4 upper and 4 lower) to provide even, controllable heat across the PCB.

The machine supports PCBs up to 280 mm wide and up to 350 mm long, making it suitable for a wide range of small to medium boards.

Transport speed is adjustable from 160 to 1350 mm/min via analog speed control to match different soldering profiles and throughput needs.

The machine requires three-phase five-wire 380V ±10% at 50Hz. Product literature lists rated power in different places (15 kW in the overview; model specs show 11 kW starting power and 3.5 kW working power). Actual consumption depends on settings and profile — confirm the exact model specification and ensure your facility can handle inrush and running load.

Temperature control range is up to 400°C (from room temperature to 400°C). The oven uses a PID closed-loop control system for precise, repeatable temperature profiles and fast, energy-efficient heating.

Typical warm-up time is about 20 minutes. The transit (pass-through) time for a board is typically 3.5–5.5 minutes, depending on transport speed and profile settings.

The unit includes two natural air cooling zones. For faster or controlled active cooling requirements, external or additional forced-air cooling solutions may be considered.

Yes — the conveyor can operate Left → Right or Right → Left, depending on production line layout and configuration.

The net conveyor belt width is 300 mm. The recommended maximum PCB width is 280 mm and the conveyor height is approximately 900 ±20 mm. The heating zone length is 1400 mm.

Yes. With PID temperature control and a maximum temperature up to 400°C, the oven is suitable for lead-free (RoHS) soldering processes and profiles.

Features include timing automatic chain dripping (an automated timed chain-lubrication/drip system to maintain conveyor performance), drawer-type heater modules for easy replacement, and external controls for temperature and belt speed for convenient operation and monitoring.

The machine is CE certified and comes with a 1-year warranty. After-warranty technical support is available via video support from the supplier.

Listed dimensions vary by documentation — example outline sizes include 2720 × 820 × 1360 mm (weight ~450 kg) and 2440 × 680 × 1200 mm (net weight ~350 kg). Exact size and shipping/crate footprint depend on the model and options, so confirm the specific model dimensions before planning installation.

Routine maintenance includes keeping the interior and ventilation paths clean, inspecting and cleaning the conveyor belt, lubricating moving parts (the automatic chain drip helps with this), and checking heater modules and electrical connections. Replace heater elements, belts or worn parts as they show signs of wear. Follow the supplier’s maintenance schedule in the manual.

Throughput depends on board size, spacing, and chosen transport speed. The oven’s typical transit time is 3.5–5.5 minutes per pass — increasing belt speed reduces transit time but requires profile adjustments. For continuous production, calculate cycle time based on your board length + spacing and selected mm/min speed to estimate pieces per hour.
