  Aluminum die-casting is a highly efficient and versatile manufacturing process widely used in producing complex and lightweight parts. This technique involves forcing molten aluminum into a mold cavity under high pressure, producing parts with excellent dimensional accuracy and surface finish. While aluminum die-cast parts are inherently strong and durable, applying a protective and decorative coating can significantly enhance their performance and longevity. Surface finishing is a critical step in the production of aluminum die-cast parts. Among various finishing techniques, painting or spraying is particularly popular due to its ability to provide both functional and aesthetic benefits. By applying a spray coating, manufacturers can protect aluminum parts from environmental damage, improve their appearance, and add specific properties tailored to the needs of different applications. Functions of Spraying on Die-Cast Parts 1.1 Protection One of the primary functions of spraying on

  MIM 4065 Low Alloy Steel Metal Injection Molding service Metal injection molding of martensitic 4605 low alloy steel delivers an exceptional combination of high strength, hardness, and corrosion resistance. The alloy contains 17% chromium for good general corrosion performance and molybdenum for enhanced pitting and crevice resistance. Significant carbon and nitrogen additions enable 4605 MIM parts to achieve hardness levels exceeding HRC 60. The fine, uniform carbide distribution imparted by MIM also provides a refinement in flexibility over conventional 4605 grades. Excellent dimensional stability is maintained during heat treatment. These balanced properties make MIM 4605 suitable for various demanding applications. With its hardness, strength, corrosion resistance, and excellent manufacturing characteristics, MIM 4605 presents an advanced low alloy steel solution for critical components across industries, including aerospace hydraulic components, measure tool parts, power tool p

  MIM 440C Stainless Steel Metal Injection Molding service Martensitic 440C stainless steel  metal injection molded parts  offer exceptional hardness, strength, and corrosion resistance. The high carbon and chromium contents enable excellent wear resistance with the ability to reach hardness levels over HRC 60. However, 440C maintains sufficient toughness and impact strength to avoid brittle behavior. But 440C has a lower ability to withstand dynamic loads. The fine carbide distribution and refined microstructure from the  metal injection molding (MIM) process  improve fatigue strength and ductility versus the  precision casting process . Post-sintering heat treatment allows ultimate tensile strengths over 2000 MPa to be achieved. The balanced properties of MIM 440C make it well suited for applications requiring high hardness for wear resistance combined with excellent corrosion performance. Typical uses include: Plastic injection molds. High-performance ball bearings. Valves. Nozzles

  17-4 PH Metal Injection Molding 17-4PH stainless steel is a precipitation-hardening martensitic stainless steel that contains approximately 17% chromium and 4% nickel as its major alloying elements. It offers an excellent combination of high strength, good corrosion resistance, and ease of machinability. 17-4PH is widely used for metal injection molded parts because it can achieve high strength and hardness through heat treatment while retaining good corrosion resistance and excellent mechanical properties. The metal injection molding process combines the advantages of plastic injection molding with excellent properties of 17-4 PH. Plastic injection molding process allows high complexity for 17-4 PH MIM parts. Precipitation hardening heat treatment allows 17-4PH MIM parts to attain high tensile strength, yield strength, and hardness needed for demanding applications.

Stainless Steel Optional for MIM The most commonly metal injection molded stainless steels are 304 and 316/316L due to their excellent corrosion resistance and easier fabrication. Precipitation-hardening alloys can achieve very high strength through aging but are more difficult to MIM. Some common stainless steel alloys are used in metal injection molding (MIM) , including: 304 Stainless Steel 316L Stainless Steel 17-4 PH Stainless Steel 420 Stainless Steel 440C Stainless Steel 430 Stainless Steel 316 Stainless Steel MIM-Stainless Steel Material Comparison Austenitic grades offer the best corrosion resistance, martensitic grades have the highest hardness and strength, and ferritic grades provide an economical option when hardness is not critical. Here is a brief comparison of standard stainless steel alloys used in metal injection molding (MIM): 304: Austenitic stainless steel. Excellent corrosion resistance and good formability. Lower strength and hardness. It is commonly used for con
