Types of MIM Parts

MIM parts are formed by mixing fine powders of metal and plastic, resulting in complex geometries for obsolete or unfeasible forms. They can be separated based on their application.

• Industrial MIM Parts: are functional pieces like bearings, which help simplify the cost in assemblies.
• Consumer MIM Parts: are final products like replaceable razor blades or precursors for other goods. They are usually characterized by intricate designs.
• Medical MIM Parts: include delicate instruments and essential devices such as surgical tools, orthopedic implants, stents, catheters, prosthetics, etc. They often feature fine detail and require strict adherence to quality and safety standards.
• Aerospace MIM Parts: include components like turbine blades, brackets, and sensors that are added to streamline tasks, enhance safety, reduce costs, or improve the efficiency of engineering processes.
• Automobile MIM Parts: can be engine components, gearbox parts, fuel injectors, connectors, and more. The material's strength makes it suitable for critical components that must withstand harsh conditions.

Specifications and maintenance for MIM parts

• Materials

  The appropriate materials are needed in MIM to make MIM parts. Certain qualities have to be met to make the MIM process viable, like plasticity and strength. Usually, metal powder like stainless steel is used for the core, surrounded by a solid and flowable polymer.

• Temperature

  The MIM process needs precise heat levels at various stages, like the debinding and sintering processes. During sintering, the temperature has to rise above 1,200°C for titanium powder to weld the particles together.

• Design Complexity

  Even geometric details are complicated, but the design of MIM parts is still simple. Parts with increased accuracy and slenderness can be made through MIM. Internal cavities and walls as thin as 1 mm can be present in designs.

• Pressure

  According to specification, an injection molding machine with a holding force of 28 tons is required to make MIM parts of this size. A different machine with a 210-ton clamping force is needed for MIM parts of this size, and it holds the mold with higher pressure.

To maintain the MIM parts properly and ensure their longevity, it is essential to clean the parts regularly cleaning them with a soft cloth. It's also necessary to keep the parts away from harmful chemicals that could damage them. Storing them in a dry environment will also help maintain them. Further, temperature fluctuations should be avoided, and they shouldn't be exposed to extreme heat or cold that could cause warping. If any parts require lubrication, it is critical to lubricate moving components with high-quality oil or grease. Finally, routine inspections should be carried out to check for any signs of wear or damage and address any issues as soon as possible.

Scenarios of MIM parts

• Medical industry:

  The medical industry demands high-precision components. MIM parts are prevalent in the field. MIM technology makes drugs adjustable for patients, enhancing medication personalization and improving patient outcomes. MIM assists in creating intricate, lightweight drug delivery devices that possess both reliability and efficiency. MIM is utilized to manufacture components for minimally invasive surgical instruments, such as endoscopic forceps. Furthermore, MIM can manufacture disposable medical equipment, like syringes and connectors, in large quantities. The production process is fast, fulfilling the need for speed in the medical industry.

• Automative industry:

  MIM parts are used in automotive applications. Luxury and performance vehicles often include automobiles that require high-performance components. These components must be robust enough to withstand harsh conditions and lightweight to enhance fuel efficiency. MIM technology is also used to manufacture intricate, lightweight automotive accessories such as knobs and handles. In addition, automobiles require many parts, including gear shafts, connectors, locks, and even lightweight aluminum parts, all of which can be made using MIM technology.

• Aerospace industry:

  The aerospace industry needs light but strong materials and products. MIM technology can create lightweight and complex engine parts. The nozzles, valves, and actuator components of spacecraft are also made using MIM technology. Another usage is aerospace fasteners.

How to choose MIM parts

Choosing metal injection molding parts requires careful consideration of various factors.

• Specify parts requirements

  To begin with, it is essential to determine the performance needs of the components. Things like strength, endurance, temperature resistance, magnetism, conductivity, hardness, and other functional requirements must be identified.

  Secondly, the geometry of the parts should be confirmed, comprising the size, weight, and complexity of the structure. Besides, it's important to ascertain the quantity of parts that need to be produced. MIM is especially cost-effective for large production volumes, typically in the thousands or tens of thousands.

  Moreover, the materials for MIM should be researched as well. MIM offers a wide range of materials, including stainless steel, tool steel, carbon steel, low-expansion steel, high-temperature alloys, nickel alloys, copper alloys, etc. Each material has its unique properties and suitability for specific applications.

  Finally, the budget constraints for the project should be considered. While MIM offers cost-effective solutions for large-scale production, it is essential to evaluate the cost implications based on materials, design complexity, and production volume.

• Find suitable MIM suppliers

  Buyers can search for suppliers who provide MIM services in bulk on platforms like Alibaba.com. When browsing MIM suppliers, remember to check the suppliers' company profile, approvals, product testing, and certification. Contact the suppliers and ask about their product-related certifications to ensure the product's quality.

  Furthermore, consider the suppliers' production capacity, technical proficiency, and experience in dealing with specific industries or applications. Strong partnerships can be forged by picking suppliers who meet specific requirements and expectations.
