Improved production volume with continuous pulling of silicon single crystals! Ideal for the preliminary door of vertical high-temperature furnaces!
The "automatic shut-off valve" is a product that enables the continuous pulling of silicon single crystals by being installed on the CZ-type pulling machine, thereby improving production volume. The interior is finished to a mirror surface, and the entire structure is cooled to block radiation heat of 1400°C (vacuum sealing). It is ideal for the preliminary door of a vertical high-temperature furnace entrance. 【Features】 - Enables continuous pulling of silicon single crystals - Increases production volume - Interior finished to a mirror surface, entire structure cooled to vacuum seal radiation heat of 1400°C - Ideal for the preliminary door of a vertical high-temperature furnace entrance *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company is a dedicated machine manufacturer that solves customer problems. We started our business in 1964 with the production of high-pressure cement tile molds. Recognized for our high technical capabilities by the former Niigata Iron Works, we began to receive orders for the supply of machine tool parts and ship parts, as well as other processing and assembly work. After relocating to our current site in 1974, we began developing and selling our own brand of forging machines (hydraulic press brakes and hydraulic shears). Acquiring our own brand has become a significant asset and source of confidence for us, allowing us to respond to the needs of various eras and companies as a dedicated machine manufacturer, including components for small vacuum devices, large vacuum systems, powder valves, and semiconductor lifting machines. Currently, we design and manufacture all dedicated machines in-house, focusing on powder and granular equipment, including rotary valves, in response to customer requests.
