At Sundar, we operate on the principle of the 3S
Speed
We understand that time-to-market is critical. Our streamlined quoting process, efficient production workflows, and fast lead times get you functional prototypes in as few as 5 days and production parts without unnecessary delays.
Stability
Consistency is the foundation of quality. Our ISO 9001:2015 certified processes, rigorous CMM inspection, and controlled manufacturing environment ensure that every part we ship — whether it’s the first or the thousandth — meets your specifications.
Service
We believe in partnership, not just transactions. You get a dedicated project manager who speaks English, works in your time zone, and provides transparent communication from quote to delivery. Free DFM feedback and full inspection reports are part of our standard service.
Who We Are?
Rooted in China, Serving the World
Sundar Industries is a privately owned manufacturing company based in Shenzhen, China. We specialize in five core manufacturing services: CNC machining, injection molding, sheet metal fabrication, metal stamping, and rapid prototyping.
Unlike trading companies or brokers, Sundar owns and operates every machine on our shop floor. This direct control allows us to manage quality, cost, and lead time with complete transparency — and pass those benefits directly to our customers. We export to customers in the United States, Germany, the United Kingdom, France, Italy, and more. Our team is experienced with international shipping, customs documentation, and packaging for safe long-distance transport.
Our Business Model
Sundar Industries bridges the gap between prototyping and production. Many engineers struggle with coordinating multiple suppliers, inconsistent quality, and slow communication. We solve this by being a single, reliable partner throughout your product lifecycle.
Rapid Prototyping
Functional prototypes in days, not weeks. Use our CNC machining, 3D printing, or vacuum casting services to validate your design quickly with production-grade materials.
Low-Volume Production
Need 1pc to 1,000 parts? We offer bridge tooling, low-volume injection molding, and short-run CNC machining to help you test the market or meet immediate demand.
Full-Scale Production
For volumes beyond 10,000 units, our injection molding, metal stamping, and high-volume CNC machining services deliver consistent quality with scalable capacity.
Our Team
Behind every precision part is a team of skilled engineers, machinists, and quality professionals. Sundar employs 80 full-time manufacturing experts, including:
Senior Tooling & Manufacturing Engineers
who provide free DFM feedback and optimize your design for manufacturability.
CNC Machinists and Toolmakers
with years of experience in complex 5-axis machining, injection mold making, and precision fabrication.
Quality Control Engineers
who operate our CMM and inspection equipment to verify every critical dimension.
Project Managers
who speak fluent English and serve as your single point of contact, ensuring clear communication across time zones.
