  • Our Customized Service Advantages
    Unlike standardized product providers, we focus entirely on "customization" and break the limitations of traditional MIM production. Every service process is independently designed and optimized for you, ensuring exclusivity and uniqueness:
    Exclusive Design & R&D Support: Our professional engineering team will work closely with you to deeply understand your product usage scenarios, performance requirements, and appearance expectations. From initial concept communication to 3D modeling, prototype testing, and process optimization, we provide exclusive R&D support, and all design schemes are only for your project, with no reuse or disclosure to third parties.
    Full-Range Material Customization: We support the customization of various MIM-compatible materials, including stainless steel, carbon steel, alloy steel, titanium alloy, and other special metals. According to your requirements for strength, corrosion resistance, wear resistance, and cost, we select the most suitable material formula and optimize the mixing process to ensure the final product meets your performance standards.
    Precision Process Control: Leveraging advanced MIM production equipment and self-developed process parameters, we achieve high-precision molding of complex structures (such as micro-sized parts, irregular shapes, and internal hollow structures) that are difficult to achieve with traditional processing methods. The dimensional accuracy can reach ±0.005mm, ensuring the consistency and stability of each customized product.
    Flexible MOQ & Fast Delivery: We understand the diverse needs of foreign clients, whether it is small-batch trial production (MOQ ≥ 5000 pieces) or large-batch mass production, we can provide flexible production arrangements. With an optimized production cycle, we shorten the customization lead time by 20% compared with the industry average, ensuring that your products are delivered on time.
  • Our Customized Service
    To ensure a smooth and efficient customization experience, we have designed a streamlined service process, with clear division of labor and full transparency at each step:
    Needs Communication: Our multilingual team (English, German, etc.) communicates with you in detail to confirm product specifications, performance requirements, material preferences, quantity, delivery time, and budget, and provides professional suggestions based on your actual needs.
    Scheme Design & Quotation: According to the communication results, our engineering team completes the 3D design, process plan formulation, and material selection, and provides a detailed quotation and project schedule, ensuring no hidden costs.
    Prototype Production & Confirmation: We produce a small number of prototypes using the customized process, send them to you for testing and confirmation, and make timely adjustments according to your feedback until the prototype fully meets your requirements.
    Mass Production & Quality Inspection: After prototype confirmation, we start mass production. During the production process, we conduct strict quality inspection at each link (raw material inspection, molding inspection, sintering inspection, finished product inspection) to ensure that each product meets the standard.
    Delivery & After-Sales Service: We cooperate with well-known international logistics companies to ensure safe and timely delivery of products to your designated location. After delivery, we provide a one-year after-sales service, and promptly solve any product quality problems that may arise during use.

FAQs

  • Q What is MIM? How is it different from CNC, die casting, and stamping?

    A

    MIM (Metal Injection Molding) is a near-net-shape manufacturing process that combines plastic injection molding with powder metallurgy.
    It is ideal for producing small, complex, high-precision parts with intricate 3D geometries.

    l Advantages:      

     ①　High design freedom

    ②　Excellent dimensional accuracy

    ③　Good mechanical strength

    ④　Cost-effective for high-volume production

    l Comparison:  

    ①　CNC: Suitable for simple geometries and low-volume production, but has higher costs and lower efficiency for complex parts.

    ②　Die Casting: Capable of producing larger parts, but generally offers lower precision, strength, and thinner wall capabilities compared to MIM.

    ③　Stamping: Limited to 2D flat or formed sheet metal parts; cannot produce complex 3D shapes.

  • Q What materials can be used with MIM?

    A

    l Stainless Steels: 304, 316L, 17-4PH.

    l Iron-based Alloys: Fe-Ni, Soft Magnetic Alloys.

    l Tungsten Alloys, Titanium Alloys (select grades).

    l Low-Alloy Steels, Tool Steels.

    l etc.

  • Q What level of precision can you achieve?

    A

    l Standard tolerance: ±0.03mm to ±0.05mm.

    l High precision: Can achieve ±0.01mm to ±0.02mm, depending on part geometry and size.

    l Note: Tolerances may be relaxed for larger parts or more complex geometries.

  • Q What are the design guidelines for MIM parts?

    A

    l Recommended wall thickness: 0.3mm to 3mm (minimum achievable: 0.2mm).

    l Avoid sharp corners and abrupt transitions between thin and thick walls.

    l Incorporate radii and draft angles where possible.

    l Complex holes, non-circular holes, and threads can be directly molded.

  • Q Can you produce threads, blind holes, and deep holes?

    A

    l Threads: Can be directly molded, eliminating the need for secondary machining.

    l Blind holes & deep holes: Feasible, but subject to aspect ratio limitations. Feasibility depends on the specific part design—please provide a drawing for evaluation.

  • Q What surface finishes are available?

    A

    l Polishing, Sandblasting,

    l Electroplating: Nickel, Zinc, Chrome, Gold, Silver, etc.

    l E-coating, Blackening (Black Oxide), PVD, Passivation, etc.
