3.混炼　

　　混炼是将金属粉末与粘结剂夹杂取得平均喂料的进程。因为喂料的性子决议了终打针成形产物的机能，以是混炼这一工艺步骤非 常主要。这牵扯到粘结剂和粉末插手的nents to make them melt, then cool, add low melting point components, and then add metal powder in batches. This prevents the low melting point components from vaporizing or decomposing, and adding metal powder in batches can prevent excessive torque increase and equipment loss. For the feeding method of powders of different sizes, the Japanese patent introduces: first add the coarser 15-40um water atomized powder to the binder, then add 5-15um powder, and then add the powder with degree ≤5um. The shrinkage of the final product changes little. In order to evenly coat a layer of binder around the powder, it is also possible to directly add the metal powder to the high melting point componenadictory. Research on MIM raw material powders includes: powder shape , Particle size and particle size composition, specific surface, etc., Table 1 lists the properties of the raw material powder suitable for MIM. Due to the very fine requirements of MIM raw material powders, the prices of MIM raw material powders are generally higher, and some even reach 10 times the price of traditional PM powders. This is currently a key factor restricting the widespread application of MIM technology. The current methods for producing MIM raw material powders are mainly There are carbonyl method, ultra high pressure water atomization method, high pressure gas atomization method, etc. 2. Binder Binder is the core of MIM technology. In MIM, the binder has two basic functions of enhancing fluidity to be suitable for injection molding and maintaining the shape of the billet. In addition, it should have easy removal and no Due to its toxicity and reasonable cost, a variety of adhesives have appeared for this purpose. In recent years, it has gradually moved from the selection of experience alone to the design of adhesives in accordance with the requirements of degreasing methods and the function of adhesives. The development of the agent system.　　 The binder is generally composed of low molecular components and high molecular components plus some essential additives. Low-molecular components have low viscosity, good fluidity and easy to take off; high-molecular components have high viscosity and high strength to maintain the strength of the formed blank. The two are matched in an appropriate ratio to obtain a high powder loading, and finally a product with high accuracy and uniformity is obtained. 3. Kneading 　　　 Kneading is the process of mixing metal powder and binder to obtain a uniform feed. Because the nature of the feed determines the performance of the final injection molded product, this process step of mixing is very important. This involves the addition of binders and powders
