13 years of proven precision machining experience delivers end-to-end manufacturing support for startups, innovators and global leaders. Complex designs are perfectly realized from first prototype to mass production.
Tenghui is one of the most reliable rapid prototyping companies. We can turn your designs and ideas into real parts in just a few days.
At Tenghui, we don’t just machine parts—we deliver production-grade functional prototypes that meet strict industrial standards. Our advanced in-house capabilities span 3/4/5-axis precision CNC machining, custom sheet metal fabrication, and comprehensive surface finishing.
With our professional engineering team manually verifying every DFM review, we bridge the gap between your engineering designs and flawless, consistent production. We empower you to test form, fit, and performance before scaling up, minimizing R&D risks and accelerating your project timelines with uncompromised quality.
At Tenghui, we bridge the gap between complex engineering designs and flawless physical production. By combining deep human expertise with multi-axis precision, we deliver the structural integrity, extreme tolerances, and flexible volumes your hardware innovations demand.
Every drawing is analyzed by a 10+ year manufacturing engineer to fix hidden design flaws and cut production costs by 15%-20%.
Specializing in high-precision milling and turning for instrument-grade parts to ensure a flawless assembly fit.
No restrictive MOQs. We provide fast 3-5 days delivery for R&D test prototypes and seamlessly scale up to volume runs.
Mature in-house chemical passivation and anodization to deliver robust protection and exquisite industrial aesthetics.
Whether for rapid prototyping or medium-volume production, we deliver engineer-verified quotes within 24 hours and flawless custom parts in days.
Operating from our 3,000+ ㎡ modernized smart facility in Chang’an, Dongguan, Tenghui utilizes over 60 advanced multi-axis CNC machining centers and precision sheet metal production lines. We specialize in manufacturing high-precision, complex industrial components and airtight instrument enclosures, reliably securing extreme tolerances down to ±0.005mm. Every single component undergoes rigorous in-house quality tracking and formal CMM dimensional inspection, fully compliant with ISO 9001:2015, RoHS, and REACH international standards. Our advanced processing capabilities proudly serve demanding global sectors, including precision optical instruments, robotics, medical devices, and industrial electronics
Our standard manufacturing tolerance for CNC machining is ±0.005” (±0.127 mm). For high-precision applications, we can achieve tight tolerances down to ±0.001” (±0.025 mm) or tighter upon request. All dimensions are verified using advanced CMM and optical inspection equipment.
We offer rapid prototyping with turnarounds as fast as 3 to 5 business days, depending on part complexity and surface finishing requirements. For low-to-medium volume production runs, standard lead time is typically 2 to 3 weeks. Expedited shipping options are available.
No, we have no MOQ restrictions. Whether you need a single prototype for design validation or low-volume production of 10,000+ units, we support your project at every stage with cost-effective pricing models.
We machine a wide range of metals including Aluminum (6061, 7075), Stainless Steel (304, 316L), Titanium, Brass, and Copper, as well as engineering plastics like PEEK, POM/Delrin, PC, and Nylon. Available surface finishes include anodizing, powder coating, bead blasting, electroplating, and mirror polishing.
Yes. Every RFQ undergoes a comprehensive Design for Manufacturability (DFM) review by our engineering team. We analyze your 3D CAD models (STEP/IGES) to identify potential machining bottlenecks, suggest optimization tips, and help reduce unit costs before starting production.
We perform 100% in-process inspection and final CMM quality control. Upon request, we provide full quality documentation with your shipment, including Material Test Reports (MTRs/ROHS/REACH), Full Inspection Reports (CMM/FAIR), and Certificates of Conformance (CoC).
If you have any questions or would like to book a session please contact us.
Once we receive your design files, our senior manufacturing engineers will manually perform a comprehensive DFM review and deliver an accurate, optimized quote within 24 hours.
