One-Stop Custom Manufacturing From Prototype to Production
Why juggle five vendors when one handles everything? Great Light delivers CNC machining, 3D printing, injection molding, sheet metal, and vacuum casting — all under one roof, with free DFM analysis and quotes returned in 2 hours.
What We Do
Ten Core Manufacturing Capabilities. One Reliable Partner.
Whether you need a single functional prototype or a bridge-production batch, every service below includes free DFM analysis, CMM-backed quality inspection, and real-time order tracking.
CNC Machining
Precision is non-negotiable — which is why our 3, 4, and 5-axis CNC milling and turning centers hold tolerances to ±0.01mm. Ideal for functional prototypes, low-volume production, and production-grade metal or plastic parts. Free DFM included.
CNC Turning
Great Light offers high-precision, custom CNC turning services widely utilized in OEM manufacturing, rapid prototyping, and mass production. We help you quickly obtain metal and plastic components with extremely tight tolerances.
CNC Milling
We offer highly competitive pricing for our CNC milling services. Leveraging advanced 3-axis, 4-axis, and 5-axis CNC milling machines, we ensure consistent product quality, exceptionally tight tolerances, and rapid delivery—regardless of the project’s scale.
Sheet Metal Fabrication
Enclosures, brackets, panels, and structural assemblies — faster and more cost-efficiently than billet machining. Laser cutting, bending, stamping, and welding all in-house. We work with aluminum, stainless steel, cold-rolled steel, and copper.
Rapid Prototyping
Rapid 3D printing, CNC machining, injection molding, sheet metal fabrication, extrusions, and other prototyping services.
Injection Molding
Ready to validate in real production materials before committing to hard tooling? Our rapid aluminum or steel molds are ready in 5–7 days, supporting 100 to 100,000+ parts. The fastest bridge between prototype and mass production.
Die Casting
One-off prototyping or 1000+ production parts
Vacuum Casting
Need 20–200 production-quality plastic parts without injection mold investment? Vacuum casting (urethane casting) with silicone molds delivers injection-molded surface quality at a fraction of the cost — ideal for investor demos, market testing, and pre-production validation.
Surface Treatment
A part is only complete when it looks, feels, and performs right. We offer anodizing, powder coating, electroplating, sandblasting, passivation, black oxide, and laser etching — achieving surface roughness below Ra 0.8μm for medical and high-spec applications.
