Satisfaction Rate
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.
Multi-axis milling for complex structural parts down to ±0.01mm tolerance.
High-speed precision turning for axisymmetric shafts and tight-tolerance bores.
Laser cutting, bending, and precision welding for rugged custom steel enclosures.
Rapid SLA and SLS additive manufacturing for functional prototype validation.
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.
The following information is for preliminary reference only. Final specifications, MOQ, and lead time are subject to product model, material, tolerance, surface treatment, and order quantity confirmation.
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 ±0.01mm. 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
Every drawing is analyzed by a 10+ year manufacturing engineer to fix hidden design flaws and cut production costs by 15%-20%.

Please send your STEP (.step/.stp) or Parasolid (.x_t) files, quantity, material, and surface finish requirements. Include a 2D PDF drawing showing any critical dimensions, tolerances, and threads.
Yes. Send your current files and let us know which requirements are still undecided. We can discuss suitable options and identify any additional information needed for an accurate quote.
We accept orders starting from a single prototype and support low-volume batches and repeat production.
Yes. We review your drawings for manufacturability and flag potential issues. Any proposed changes to your design, material, or specifications require your approval before production.
We typically provide quotes within 24 hours of receiving complete project details. Simple prototypes may take 3–5 days to manufacture. Your production lead time is confirmed with your quote.
We inspect parts against the agreed drawings and specifications. Please specify any required material certificates, dimensional inspection reports, or CMM reports when requesting a quote.
Yes. We support both prototyping and production, confirming specifications, quantities, and inspection requirements before each order.
Yes. We can review and sign an NDA before you share your files. Your drawings and project information are kept confidential.
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.
