Product Description

Metal powder injection molding is a high-tech technology that uses mold injection molding and rapidly manufactures high-density, high-precision, three-dimensional complex-shaped structural parts through sintering.

Stainless steel powder is one of the most used material for MIM. 304L Stainless Steel Powder(ss304L) 304L is a stainless steel grade, which is classified according to the metallographic structure and belongs to austenite stainless steel. The standard grade of the America is AISI304L; the Japanese JIS industrial standard grade is SUS304L; Nitrogen Atomization Spherical Stainless Steel Powder has the characteristics of low oxygen content, high tapping density. It can be widely used in electronic information engineering, biomedical equipment, office equipment, automobiles, machinery, aerospace, etc.

Applications

How we play a role in the industry

HIP Technology

Hot Isostatic Pressing (HIP) technology works by placing the product in a closed container, filling it with inert gas and sintering or densifying the product at a very high temperature (usually close to the forging temperature of the material) and at a very high pressure (usually 100 – 140 MPa). This allows the product to be sintered or densified.

MIM Technology

MIM products can be complex in shape, precise in size, high in strength and produced automatically in large quantities, and can significantly reduce the complexity and cost of traditional metalworking

SLM Technology

SLM, also known as Selective Laser Melting, is similar in principle to SLS in that a laser is used to melt and solidify metal powder in a specified area, which is then moulded in a layer-by-layer stack.

EBM Technology

Electron beam melting refers to a vacuum melting method in which the kinetic energy of a high speed electron beam stream is converted to heat as a heat source for melting metals under high vacuum. The abbreviation is EBM.
