Precision Metal Injection Molding Services for Custom Precision Parts

High-Volume Precision Parts — From Grams to Mass Production

JINGYE provides integrated Metal Injection Molding Services for small, precise and geometrically complex metal components. The service covers material and feedstock selection, drawing review, injection molding, debinding, controlled sintering, sizing, secondary machining, surface finishing and inspection. It is designed for repeat production where consistent geometry, metal performance and unit-cost control must be achieved together.

 

As a MIM Parts Manufacturer with in-house metal powder and feedstock development capability, JINGYE can coordinate powder characteristics, molding behavior and sintering shrinkage during process development. This materials-to-parts capability supports Custom Metal Injection Molding projects in consumer electronics, precision hardware, industrial equipment, automotive systems and medical devices.

 

Is Metal Injection Molding Suitable for Your Part?

Project Characteristic Why MIM Is Suitable
Small parts with complex three-dimensional geometry Features such as holes, grooves, ribs, teeth and irregular profiles can be formed in one molding cycle.
Repeat or high-volume production Tooling cost can be distributed across production volume while maintaining consistent part geometry.
Parts requiring multiple machining or assembly operations Near-net-shape molding can reduce cutting, joining and repeated setup operations.
Material, strength or corrosion requirements Stainless steels, precipitation-hardening steels, soft-magnetic alloys, copper, titanium, cobalt-chromium and nickel systems are available.
Tight functional dimensions Sintering shrinkage, distortion risk and machining allowance can be planned around critical drawing dimensions.

JINGYE reviews part size, weight, wall thickness, tolerance, annual demand and finishing requirements before recommending Custom Metal Injection Molding. CNC machining may remain more suitable for low-volume or frequently changing designs, while conventional powder metallurgy is generally more economical for simpler geometries.

 

MIM Materials and Selection Priorities

Material Family Available Grades Selection Focus
Stainless and high-strength steel 304L, 316L, 17-4PH, 440C, G19 Corrosion resistance, strength, hardness, wear resistance and heat-treatment response
Iron-nickel soft-magnetic alloy FeNi8, FeNi30, FeNi50 Magnetic response for electromagnetic and sensor components
Copper alloy Pure copper, Cu20, Cu40 Electrical conductivity, thermal conductivity and corrosion performance
Titanium alloy TC4 (Ti-6Al-4V) High strength-to-weight ratio and corrosion resistance
Cobalt-chromium alloy F75 Wear resistance, corrosion resistance and non-magnetic performance
Pure nickel and special alloys Ni200 (N6 / N02200) and project-specific systems Corrosion resistance, conductivity and special service conditions

JINGYE has developed MIM feedstock for multiple alloy systems and operates a dedicated validation line for powder and feedstock trials. More information about particle-size distribution, tap density and available grades is provided on the MIM powder page.

 

JINGYE MIM Manufacturing Capacity

  • ♦  15 MIM production lines: current daily production capacity reaches up to 30,000 components.
  • ♦  In-house feedstock development: material formulation and shrinkage behavior can be coordinated with the part-manufacturing process.
  • ♦  Complete production route: mixing, injection molding, debinding, sintering, sizing, inspection, finishing and packaging are controlled within the manufacturing workflow.
  • ♦  Secondary operations: CNC finishing, internal-hole grinding, tapping, heat treatment, polishing, sandblasting and passivation are available according to the drawing.
  • ♦  Inspection capability: dimensional, density, hardness, tensile, corrosion, composition and microscopic testing can be incorporated into the inspection plan.
  • ♦  Quality and documentation: ISO 9001 and GJB 9001C quality-management requirements are supported; RoHS and REACH compliance documentation and material safety data are available where applicable.

This integrated capacity allows JINGYE to operate as a MIM Parts Manufacturer for both product development and repeat production, with process control extending from metal powder and feedstock to finished-part inspection.

 

Information for a Custom MIM Quotation

For an engineering review, provide the available 3D model and 2D drawing, target alloy, estimated annual quantity, critical dimensions and tolerances, surface-finish requirement, heat-treatment requirement, application environment and inspection standard. JINGYE will review MIM feasibility, shrinkage control, tooling considerations, secondary operations and the proposed quality plan before confirming the Metal Injection Molding Services quotation.
