Manufacturing Services
Quick Answer
Emitech's manufacturing services cover the full production lifecycle of precision metal components, from design review and tooling to final inspection and delivery. We specialize in metal injection molding (MIM) for high-volume, geometrically complex parts and CNC machining for prototypes, low-volume runs, and tight-tolerance finishing. With in-house tooling, material selection, quality inspection, and surface treatment capabilities, we help engineers reduce lead times, consolidate suppliers, and improve part performance across automotive, medical, electronics, and industrial markets.

Our Core Manufacturing Capabilities
Choosing the right production method depends on part geometry, volume, material, and tolerance requirements. At Emitech, we guide customers through this decision by offering two complementary manufacturing services: MIM for net-shape complexity at scale, and CNC machining for precision, flexibility, and speed.
Both services are managed under a single project workflow, so you do not need to coordinate multiple vendors. Our engineers evaluate your CAD files, recommend the most cost-effective process or combination of processes, and validate quality at every stage. This integrated approach reduces communication overhead, prevents tolerance mismatches, and accelerates time to market for new products. When a single part benefits from both technologies, we also manage MIM + CNC secondary operations internally, ensuring tight handoff control and consistent scheduling.
MIM + CNC Dual Production Line Comparison
The table below summarizes how our two primary production lines compare across key engineering and commercial criteria. Many customers start with CNC prototypes to validate fit and function, then transition to MIM tooling once volumes justify the investment.
| Capability | MIM | CNC Machining | Best Use Case |
|---|---|---|---|
| Part Complexity | Excellent for intricate 3D geometries, undercuts, thin walls, and internal features | Excellent for precise external features, threads, bores, flats, and tight tolerances | MIM: complex net shapes; CNC: critical finishing dimensions |
| Typical Volume | 10,000 to millions of parts per year | 1 to 10,000 parts per year | MIM: mass production; CNC: prototypes and low-volume |
| Material Range | Stainless steels, low-alloy steels, tool steels, titanium, copper, Kovar | Most machinable metals and engineering plastics | MIM: powder metals; CNC: broad metal and plastic selection |
| Tolerance | ±0.3% to ±0.5% typical, with selected features tighter | ±0.01 mm to ±0.05 mm typical | MIM: near-net shape; CNC: ultra-precise final dimensions |
| Lead Time | Tooling 4-6 weeks, first article 1-2 weeks after tool approval | Prototype 3-5 days, production 1-3 weeks | MIM: longer setup, faster unit output; CNC: faster startup |
| Surface Finish | Good as-sintered; improved with polishing, passivation, coating | Excellent machined finish; ready for anodizing, plating, coating | MIM: cosmetic after treatment; CNC: precision finish directly |
| Cost Driver | Upfront tooling; low per-part cost at volume | No tooling; higher per-part cost and machine time | MIM: high volume; CNC: low volume or large parts |
How MIM and CNC Work Together
Many precision parts benefit from a hybrid workflow: MIM delivers the complex near-net shape, and CNC machining adds critical threads, bores, and tight-tolerance surfaces. Emitech manages both processes under one roof. Learn more about MIM + CNC secondary operations or compare the processes in our MIM vs CNC machining guide.
Metal Injection Molding (MIM)
Metal injection molding is ideal for producing small, complex metal parts in large quantities. The MIM process mixes fine metal powder with a binder, injects it into a precision mold, then removes the binder and sinters the part to near-full density.
- Net-shape production of intricate geometries
- Materials including stainless steel, low-alloy steel, titanium, and copper alloys
- Tight tolerances and excellent surface finish
- Cost-effective at volumes from 10,000 to millions of parts
Our team supports MIM tooling design, material selection, and process optimization to ensure every batch meets specification. Whether you need surgical instrument components, automotive sensors, or electronics hardware, MIM delivers consistent quality with minimal secondary operations.
CNC Machining Services
When your project requires rapid prototypes, low-to-medium volumes, or post-processing of MIM components, our CNC machining services provide the flexibility and accuracy you need. We operate advanced CNC milling and CNC turning centers with modern multi-axis capability.
- Rapid prototyping and short lead times
- High-precision tolerances for critical fits
- Wide range of metals and engineering plastics
- Ideal for low-volume, large, or highly toleranced parts
CNC machining is often used alongside MIM to add threads, bores, flats, or finishing features that would be difficult or costly to mold directly. This hybrid approach gives customers the best of both technologies: MIM efficiency for complex shapes and CNC accuracy for critical dimensions. We also machine standalone components such as shafts, brackets, housings, and connectors from bar stock or castings when MIM is not the right fit.
