为什么选择 Winson？-- Built on 15 years of manufacturing and 12 years of procurement expertise.
DFM Support
We're not just a manufacturer -- we're your consultant. Free drawing optimization before prototyping: adjusting R-angles and tolerance settings to save you 20%-40% in costs.
Rapid Prototype Response
With in-house raw material inventory and our CNC center, standard prototype cycles are reduced to 7-14 business days -- keeping your R&D timeline on track.
Small Batch to Mass Production
Supporting R&D institutes needing 1-10 development pieces, all the way to industrial clients requiring tens of thousands in mass production -- same quality, any scale.
Supply Chain Transparency
Every order connects directly to Iris and the engineering team. Real-time production milestone updates -- eliminating the "black box" anxiety of overseas sourcing.
Customization in Action
定制实战：解决真实的工程难题 -- Three cross-product cases demonstrating the breadth of our capabilities.
Custom Sapphire Dome for Aerospace Detector
Challenge
Aerodynamic heating during high-speed flight combined with severe impact forces required a non-standard curved geometry with extreme thermal stability.
Solution
High-strength asymmetric sapphire dome with 3D CNC grinding, Ra <0.5nm polish, and operating range validated at -40°C to 800°C.
Dead-Front Mirror Glass for Smart Home Display
Challenge
The device needed to look like a mirror when off, while maintaining uniform light transmission when the screen was active -- demanding precise coating control.
Solution
Custom mirror silk-screen + AG coating on tempered glass panel with calibrated transmission uniformity across the display area.
Sapphire + Hastelloy Assembly for Chemical Sensor
Challenge
Repeated sealing failures in strong acid environments due to thermal expansion mismatch between the optical window and metal housing.
Solution
Glass-to-metal bonding with sapphire window hermetically sealed into Hastelloy C-276 housing, achieving IP69K with full chemical resistance validation.

Customization FAQ
定制化 FAQ：工程师常问的问题 -- Honest answers from our engineering team.
Don't see your question here? Our engineering team is available for a direct technical consultation.
Ask Iris DirectlyCan you work from a rough sketch instead of a CAD file?
Yes. Our engineering team can convert your dimensional description or rough sketch into a formal technical drawing. Simply send us your measurements, application requirements, and any reference images -- we'll produce a proper CAD file for your review and approval before prototyping begins.
Do you offer reverse engineering services?
Absolutely. If you have an existing sample but no drawings, we can perform reverse measurement and mapping to create accurate technical documentation. We'll also identify any design improvements -- such as material upgrades or tolerance optimizations -- that could reduce cost or improve performance.
What is the minimum order quantity for prototyping?
We support orders starting from a single piece (MOQ = 1) for R&D and development phases. There is no minimum quantity barrier -- we believe in growing alongside our clients from proof-of-concept all the way to mass production.
How do you handle NDA and IP protection for custom designs?
We sign Non-Disclosure Agreements before any technical drawings or specifications are shared. Your design files are stored in a restricted-access system, accessible only to the assigned engineering team. We do not share, replicate, or resell any custom design to third parties -- ever.
What documentation do you provide for compliance (RoHS, REACH, ISO)?
We provide full compliance documentation including ISO 9001 certificates, RoHS and REACH compliance declarations, material test reports (MTR), and inspection reports (COC/COA). These are standard inclusions for all production orders destined for the EU and North American markets.
Can I visit the factory or arrange a third-party audit?
Yes -- and we actively welcome it. Factory visits to our Shenzhen facility can be arranged with advance notice. We also accept third-party audits (SGS, Bureau Veritas, etc.) and virtual factory tours via video call. Transparency is a core value, not just a claim.
Still have technical questions?
We respond to every engineering inquiry within 24 hours.
