Automatic Power Transmission Gear Reducer Planetary Gearbox Reduction Gear Box for Gear Motors

We are a precision planetary reducer gearboxes manufacturer for electricmotors ,electric machine,electric machinery.We supply variety custom made gear box and gears for power transmission through powder metallurgy process .Powder metallurgy(PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.The powder metallurgy press andsinterprocess generally consists of three basic steps: powder blending (pulverisation), die compaction, and sintering. Compaction is generally performed at room temperature, and the elevated-temperature process of sintering is usually conducted at atmospheric pressure and under carefully controlled atmosphere composition. Optional secondary processing such ascoiningorheat treatmentoften follows to obtain special properties or enhanced precision.
