Product Introduction

Powder metallurgy is the industry technology producing metal powder or use metal powder (or the mixture of metal powder and nonmetal powder) as raw material, after forming and sintering, to make out metal, composite materials and various types of products. At present, the powder metallurgy technology has been widely used in transportation, machinery, electronic, aerospace ,weapon, biological, new energy, information and nuclear industry areas, it becomes one of the most dynamic branches of the new material science. The manufacture of powder metallurgy materials contains the process of raw material powder preparation, sintering after powder forming into the required shape and briquette and product after processing procedures; SIEHE Industry design of Powder Metallurgy Complete Production Line mainly aim at the preparation of raw material powder and subsequent processing products, it has provide equipment and project construction services for many domestic powder metallurgy production enterprises.

      Working Principle

      1. Preparation of raw material powder. Milling method now can be divided into two categories: mechanical method and physical chemistry method. The mechanical method can be divided into mechanical crushing and atomization method; Physical chemistry method can be divided into electrochemical corrosion method, reduction method, chemical combination method, reduction-chemical combination method, vapor deposition, liquid phase deposition, and electrolytic method. The most widely used method is the reduction method, atomization method and electrolysis method.
      2. Powder formed into the required shape of briquette. The purpose of forming is to make out certain shape and size of pressed shape, and make it with certain density and intensity. Forming way can be basically divided into extrusion forming and zero pressure molding. The most use of extrusion forming is the compression molding.
      3. The compact sintering. Sintering is a crucial process in powder metallurgy process. After formed compact by sintering will obtain required finally physical and mechanical properties. Sintering is divided into unit sintering and multi-component sintering. For unit system and multiple system of solid phase sintering, the sintering temperature lower than the melting point of metal and alloy; For multi-component system of liquid phase sintering, the sintering temperature is generally lower than the melting point of the refractory compounds, but higher than the melting point fusible components. In addition to the ordinary sintering, there are special sintering process such as apparent sintering, infiltration method, and hot-pressing method. .
      4. Product after process treatment: After sintering processing, can adopt a variety of ways according to different requirement such as sizing, immersion oil, machining, tempering, and electroplating. Besides, in recent years, some new technology such as rolling, forging is used in powder metallurgy material after sintering processing, which obtain ideal effect.
