MOLDING UNIT

All molds, apparatus and fixtures for press, heat treatment and assembly units are produced in molding room of Dönmez Clutch. Periodic maintenance of these molds is also carried out in molding room.

Our company has been aiming to design and manufacture all the necessary equipments within the production process by acting with the consciousness of keeping the quality above all else, technological innovation and human focus.

The mold unit is one of the most important units that make the most contribution to the realization of these targets. In particular, it consists of a total of 26 employees with two designers who are most affected by the technological change and who closely follow the technology. The unit has three vertical machining center, one universal milling machine, two universal turning machine, two wire erosion machine, three surface grinding, one cylindrical grinding, one sinking erosion machine, thread cutting machine, jigsaw machine and radial drilling machine.

Some important studies done in the mold unit:

a) Hot and cold forming molds: Progressive, cutting, punching, bending, stamping, ironing, assembly, steel forging, aluminum forging, deburring and calibrating molds

b) Casting pattern: Production and multiplication of cover, pressure plate, bearing, flywheel models.

c) Manufacture of apparatus and special equipment: Special apparatus and machines (turning, milling, drilling apparatus and fixtures, cutting tools etc.) are designed and manufactured according to the specific work piece for machining and the other production units.
