mim sintered garden tool spare parts - HR198

Sintered Parts are widely used for machinery, house hardware, garden, agricultural machines, electrical power tools and etc.

The so called powder metals have 3 major advantages: (A) high precision due to mold-based production (B) low price due to its inherent feature of automation for mass production, and (C) flexibility of material composition due to wide variety of powder formula on Fe-Ni alloy.

The process consists of mixing fine metal powders with thermoplastic binders to form a feedstock which is injection molded into a closed mold. After ejection from the mold, the thermoplastic "binders"are chemically or thermally removed from the part so that the part can be sintered to high density. During the sintering process, the individual particles metallurgically bond together as material diffusion occurs to remove most of the porosity left by the removal of the binder. The sintering process shrinks the part, providing a net shape that can be used as-is or further worked to add additional features or improve tolerances.

More than 200 types of vehicle parts and motorcycle parts, i.e., metallurgical parts, are made of sintered metals. This implies that the safety of long-term operation for sintered parts (or powder parts ) is pretty ensured. At last, in order to improve the ductility and elasticity of sintered metals (or sinter metal, sinter parts, sinter bush, sinter gear ) in machinery, the alloy that includes copper and iron becomes the main stream. This is only available by employing the technology of powder metallurgy and sintering. Since 2006, Hengrui has been providing the sintered parts for mechanical parts buyers such as Sainty, Shimano. Besides, we supplied sintered metal parts for Medical equipment makers such as Frankenman. Power tool is another giant buyer such as Emerson and Black & Decker.

The material can be customerized by chemical composition formula so that most mechanical strength such as ductility, tensile strength and hardness can be fulfilled at the same time. Since it is made by molds, then the tolerance of dimensions can be up to 5 microns or better. The delivery cycle can be shortened and the unit prices can be further reduced owing to mass production so that enormous stock in conventional manner is not completely necessary for the buyers. You will not regret to use our metal products.
