  Neway's Role in Powder Metallurgy As a trailblazer in Powder Metallurgy and Metal Sintering , Neway has carved a niche in producing Metal Injection Molding (MIM) parts . With a rich legacy and a relentless pursuit of innovation, Neway has consistently delivered precision-engineered sintered metal parts to various industries. At the same time, Neway has summed up the experience in 30 years of custom sintering metal parts manufacturing career and has made outstanding achievements in the fields of Self-Lubricating Sintered Bearings, tungsten alloy pressing and sintering forming, and the manufacture of porous metal parts. Neway's Contribution to Powder Metallurgy Neway's prowess in Powder Metallurgy is evident in its ability to produce intricate, high-precision parts in large volumes. The company's proficiency in choosing the suitable metal powder, molding it into the desired shape, and executing the sintering process to form a solid piece sets it apart in the industry.

  Sintered Gears Bushings Overview Sintered self-lubricating gears, bushings, and bearings refer to powder metallurgy components with porosity and impregnated lubricants to provide continuous lubrication during operation without needing external lubricant replenishment. Compared with solid gears, bushings, and bearings, they are lightweight, porous, self-lubricating, and high-strength. We usually use two kinds of powder metal manufacturing methods to produce sintered gears and self-lubricating bushings, namely metal injection molding and powder compression molding , which belong to the powder metallurgy process. Solid metal gear, bushings manufacturing methods The primary manufacturing processes for solid metal gears and bushings each offer distinct advantages. Gear machining allows high-precision profiling and finishing, but casting provides near-net shape capability. Forging improves strength through grain flow shaping. Bushing machining enables tight tolerances and surface finish

Metal injection molding (MIM)  has revolutionized the production of intricate metal parts, offering unique advantages in terms of design flexibility, cost-effectiveness, and material properties. For purchasing and parts design engineers, understanding the process of powder metallurgy and metal injection molding is crucial to make informed decisions and effectively leveraging its benefits.   The Origins of Metal Injection Molding The roots of metal injection molding can be traced back to the powder metallurgical industry , which has a long history of utilizing powdered metals to create various components through the powder metallurgy process. Powder metallurgy involves producing metal parts by compacting and sintering metal powders, including powder steel, powder titanium, and powder tungsten. Also was called the powder pressing molding process . However, traditional powder metallurgy techniques had limitations when manufacturing complex shapes with high precision. Historical background
