Designed and manufactured according to user needs (with dual-zone, three-zone, multi-zone), you can pre-vacuum (high vacuum, low vacuum), through a variety of atmosphere (gas flow system has a proton and a float flow control device). Vacuum pumps, valves, using imported equipment and reliable performance.Fuzzy PID programmable control circuit used technology, with high precision temperature control, temperature overshoot amplitude is small, reliable, easy to operate and so on. In the warm-up way with automatic pre-heating process. Under the program entirely without operator monitoring, adjusting the operating current can be staff from tedious operation freed.
