Overview: How Metal Injection molding Service works?

The Basics of Metal Injection Molding Services

Metal powder injection molding is one of the most commonly used manufacturing processes for making metal parts. Because the powder injection molding process has the characteristics of high precision, repeatability, high product stability, low cost, and fast speed, it is widely used in the manufacture of various products and parts. The products serve electronic products, household appliances, mechanical equipment, medical equipment, the military industry, the aerospace industry, etc.

How MIM Metal Injection Molding Works?

MIM Injection process

Clamping: The two sides of the mim mold are combined and closed.

Injection: The powder material is fed into the machine through the feed port and pushed to the mold under pressure

Melt: The molten material in a fluid state is then injected into the mold

Cooling: The material in the mold, cools and solidifies into the shape of the part.

Ejection: After the part has cooled, it is ejected from the mold.

 

Sintering process

Degreasing

Degreasing methods are divided into degreasing solvent degreasing + thermal degreasing and degreasing siphon – thermal degreasing two ways, the adhesive in the green product is separated from the product.

MIM Sintering

through the vacuum sintering furnace, the product is sintered and hardened, and the pores formed after shrinking and degreasing are formed to form the final product.

Shaping

some stainless steel materials (such as SUS 316L,17-4PH steel,420 stainless steel, and so on), are prone to deformation after the sintering process, and it is necessary to correct the deformed part by shaping.

Advantages and Disadvantages of Metal Injection Molding Services

Advantages of injection molding

Material:

We offer many powder metal materials available:

Stainless steel: SUS 304L , Stainless steel 316L,420ss ,steel 440,sus630,17.4ph

iron:4605 steel

titanium:TC21 TC17 TC18

ceramics: zirconia, Aluminium oxide

High-precision and high-density

Compared with the traditional powder metallurgy process, it can provide products with higher density, better product physical properties, smaller tolerances, and higher precision.

low cost

Due to marginal benefits, the cost of producing more than 5,000 pieces of products is much lower than the cost of CNC-processed products,

Stability

Because the industry is produced through molds, it has a high degree of consistency and can ensure the stability of product batches. 

Quick

Rapid prototyping, tooling ready in 25-30 days, parts shipped in 25-30 days

Surface Quality

The injection mold is precision CNC milled and polished to give the part an excellent surface. It can reach a roughness of Ra0.3.

 

The disadvantage of injection molding

Structural constraints

Some products with special structures are difficult to be integrally formed by injection molding.

High cost in small batches

Since the MIM process needs to produce MIM molds first, the cost is too high for the production of small batch products (quantity less than 1000 pieces).
