Customized Electronic Product Accessories by Metal Injection Molding Process MIM
Metal injection molding is cost-effective compared to other manufacturing processes when producing complex shape, small size metal components in large quantity, and what else can we do to save more money? Purchasing Cost The purity of powder metallurgy products is generally between 95%-98%, and the procurement cost of raw materials is equal to the cost of each gram of metal materials multiplied by the part volume and the part density. So to control the cost, the volume of the part must be precisely calculated. How to Produce The pressure required is different depending on the product requirements, so the cost will vary. MIM products use less suppression equipment, and the speed should be fast. Control the Mold Cost We need to choose high-pressure materials when selecting mold materials, which can ensure more accurate product specifications.

This success is due to the technology provided by other metal forming technologies, such as forging and metal casting, material utilization, shape complexity, near net shape size control, which includes the advantages of other metal forming. These, in turn, contribute to sustainable development, so that powder metallurgy is a recognized green technology.
Powder metallurgy is a metal forming process which is heated by a metal powder below its melting point. Although this process has been in existence for over 100 years, it has become recognized as an important way of high quality in the last 25 years, and has a variety of important applications.
Â
In reality, powder metallurgy includes several different technologies for producing semi-dense and fully dense assemblies. The traditional powder metallurgy process, referred to as sintered ore, is used to produce the planet carrier.
Â
In the process of metal injection molding (MIM), the operation of the scissors is made by hot pressing, and the production of the powder forging connecting rod is adopted. At the same time, metal additive manufacturing is gradually popularized.
Â
Using many of these powder metallurgy processes, as well as other processes, such as spray forming, roll compaction, rapid solidification, and parts are usually made of particulate metal rather than metal powders. Today's advanced materials are rarely made of metal and metal alloy, usually including ceramic, ceramic fiber and metal compounds.
Metal Injection Molding (MIM) is an established and proven manufacturing technique for producing small, complex, tight-tolerance and high-performance metal parts. MIM is a cost-effective alternative to traditional metal forming techniques such as machining, investment casting, and powder metallurgy. MIM excels at applications that require shape complexity and material properties (high strength, magnetic permeability and corrosion resistance) that cannot be fulfilled by plastic and light metal alloys. It offers tremendous single-step parts consolidation potential that makes it a competitive alternative to stamped/machined-parts assemblies. Many design and economic limitations of traditional metalworking technologies can be readily overcome by MIM.
Today, MIM is serving critical performance applications in a wide range of industries and products including, automotive, commercial aerospace, cellular telephones, dental instruments, electronic heat sinks and hermetic packages, electrical connector hardware, industrial tools, fiber optic connectors, fluid spray systems, hard disk drives, pharmaceutical devices, power hand-tools, surgical instruments, and sporting equipment.

The viscosity of products increases with the increasing of solids content. When the solids content reaches 62%, the viscosity increases sharply after injection, allowing the solids content limit (up to 62%). When the binder is not enough, there is a gap between the two products will affect the powder, excessive mechanical strength of the binder, the solid content is too low, affecting degreasing, sintering shrinkage.How to Control the Cost During the Process of MIM?
