In June 2025, a new type of machine, the "Spring Unwinder SU-300," was completed to prevent springs from getting tangled. Significant improvements have been made from the conventional model, allowing springs that could not be unwound by the parts feeder to be further unwound. It can be operated easily by anyone without damaging the springs, reducing not only the work time but also the burden on workers. The new model can handle a larger quantity of unwinding and is compatible with the speed of polishing machines. By simply changing the attachment, it can accommodate several types of springs.

The "SBC Series" is an environmentally friendly conveyor furnace that enhances heat retention, features a double cover, and reduces the outer surface temperature of the furnace body. By rolling the mesh belt with a unique rolling machine, we have reduced the snagging of extremely small springs. In the old Morita-made MBC conveyor furnace, we were able to maintain a stable tempering within a temperature difference of ±10℃, but by improving the heat retention effect inside the furnace, we have reduced the heater capacity by about 10%. 【Features】 ■ Space-saving with a total length of 1150 mm ■ Stable tempering even with a short length ■ Prevention of workpiece snagging ■ Easy maintenance with an assembly method ■ Maximum temperature of 450℃ *Drawings can be downloaded from the PDF.
