About Emitech
Quick Answer
Emitech (Nanjing Emitech Technology Co., Ltd.) is a MIM manufacturer in Nanjing, China. We operate one integrated production site in Jiangsu Province that delivers metal injection molding, CNC machining, and surface treatment for automotive, medical, industrial, and electronics customers worldwide. Our single-site model keeps engineering, tooling, production, and quality inspection under one roof, so we can control lead times, repeatability, and cost from first article through serial production. Our single-site production in Nanjing supports projects from prototype through high-volume production.
Our Factory Story
Emitech is based in Nanjing, Jiangsu Province, a manufacturing hub near Shanghai with strong supply-chain access and engineering talent. From the beginning, the company focused on metal injection molding as a repeatable way to produce complex metal parts at volume without the waste of conventional machining.
Our engineering and quality teams combine shop-floor experience with formal training in materials science, mold design, and metrology. Our team retains its people over the long term, which means project knowledge stays inside the company instead of walking out the door with every new order. This continuity is especially valuable for long-life automotive and medical programs that require stable process parameters year after year.
Over the years we added CNC secondary operations, a quality lab, and finishing processes, but we deliberately kept everything on one site. Our single-site model means a part engineer can walk the MIM process floor in the morning, review CMM data at lunch, and adjust tooling the same afternoon. There are no hand-offs between distant factories, no blame-shifting, and no hidden logistics delays.

Emitech supplies precision MIM and CNC parts to OEMs in automotive, medical devices, consumer electronics, industrial tools, and firearms. Our parts are shipped to North America, Europe, and Asia.
Capabilities
Our manufacturing services are built around MIM, but we offer the secondary processes that turn a sintered component into a production-ready part:
- MIM core process — Compounding, injection molding, solvent/catalytic debinding, vacuum sintering, and sizing.
- CNC machining — Turning, milling, drilling, tapping, and grinding for critical dimensions.
- Surface treatment — Passivation, electropolishing, plating, PVD, shot peening, and tumbling.
- Quality assurance — CMM, optical comparator, density testing, metallography, and full traceability.
- Engineering support — DFM, mold design, shrinkage compensation, and inspection documentation.
- Prototyping & small batches — Rapid tooling and bridge production to help you validate designs before committing to full-scale molds.

Documented Quality Management System
Quality is not a final inspection step; it is designed into every stage of our process. Emitech operates under a documented quality management system that covers quoting, design review, incoming raw-material verification, in-process inspection, final audit, and shipment. We document process parameters, maintain calibration records, and retain traceability data for each lot. Customers receive inspection reports, material certificates, and dimensional data on request.
We calibrate measurement equipment on schedule, conduct regular internal audits, and review supplier performance quarterly. Non-conforming material is segregated and analyzed, and corrective actions are tracked to closure. This disciplined approach is what allows us to consistently ship MIM parts that meet drawing requirements and customer expectations.
Why Work With Emitech?
Fast Communication
Our sales and engineering teams are fluent in English and understand machining, so requirements do not get lost in translation.
Fast Response
We reply to most RFQs within 24 hours and provide DFM feedback along with the quote.
Fast Delivery
Because MIM, CNC, and finishing sit on one floor, parts move straight from sintering to machining without cross-border shipping.
Well-Equipped Facility
Injection, debinding, sintering, CNC, surface treatment, and metrology are all in-house under one documented quality management system.
Quality Control
Every lot is traceable through our ERP, with dimensional inspection reports and material certificates (mill certs) available.
Flexible MOQ
We accept prototype and bridge-tooling orders, then scale smoothly to multi-cavity high-volume production.
Engineering & Leadership Team
Our technical team brings together materials science, mold engineering, and precision manufacturing experience. Key team members have long tenure at Emitech, providing the process stability and institutional knowledge that high-mix, long-life production programs require.

Frequently Asked Questions
Q: Where is Emitech located?
A: Emitech is located in Nanjing, Jiangsu Province, China. We have always operated from the same region, building our process knowledge and supplier relationships around a single manufacturing site. From this site we have grown into a full-service precision manufacturer serving customers in North America, Europe, and Asia.
Q: Is Emitech a trading company or a factory?
A: We are a factory. We operate one integrated production site in Nanjing that houses MIM injection, debinding, sintering, CNC machining, surface treatment, and quality inspection. There is no separate outsourced production layer between us and your parts.
Q: What materials can Emitech process?
A: Our portfolio includes stainless steels such as 316L, 304, 17-4PH, 420, and 430L; low-alloy steels such as 4605 and 8620; titanium Ti-6Al-4V; soft magnetic Fe-Ni alloys; and specialty alloys such as Kovar ASTM F15 and cobalt chrome ASTM F75. Details are available on our MIM materials page.
Q: How does Emitech manage quality?
A: We operate a documented quality management system. It covers incoming material verification, in-process inspection, final dimensional inspection, metallographic analysis, and full lot traceability. We also provide dimensional inspection reports and material certificates (mill certs) for automotive and medical customers.
Q: Does Emitech offer CNC machining in addition to MIM?
A: Yes. We operate a CNC machining cell for secondary operations such as drilling, tapping, turning, milling, and grinding. Combining MIM with CNC machining lets us hold tight tolerances on critical features while keeping complex geometry cost-effective. This one-roof combination also shortens lead times because parts do not need to be shipped between separate MIM and machining vendors.
Q: What surface finishes are available?
A: We offer passivation, electropolishing, plating, PVD coating, shot peening, and tumbling. Surface finish requirements are reviewed during DFM so the correct process is built into the routing rather than treated as an afterthought.
Q: How can I request a quote?
A: Send your drawings, 3D models, material specification, and estimated volume to mim@mikeshoppingroom.com or message us on WhatsApp at +86 138 1403 4409. We typically respond within 24 hours. For complex projects, we will also include a preliminary DFM note and tooling timeline so you can evaluate feasibility before placing an order.
