MIM Custom Manufacturing
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.
| 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.
| 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.
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.
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.

Detailed Capabilities
1. Molding Process
Metal Injection Molding (MIM) mixes metal powder with a binder to form a feedstock, which is then injection molded, catalytically debinded, and vacuum sintered to obtain high-density, high-precision, and complex-shaped metal structural parts. It is particularly suitable for small-part, high-volume, highly complex, and highly consistent products.
