Corporate Purpose
Bridging the Gap from Concept to Factory Floor
We are not a trading intermediary. We are dedicated technical manufacturing partners committed to mechanical integrity, aesthetic refinement, and repeatable quality.
The Challenge in Modern Contract Manufacturing
Many independent brand owners, industrial designers, and established luxury houses know exactly what they wish to produce. However, finding a manufacturing partner capable of translating 2D design concepts or 3D files into robust, production-ready blueprints without sacrificing micrometer tolerances or finish fidelity is notoriously difficult.
Traditional factories often resist engineering support for emerging collections, while conventional export traders introduce communication lag, lack hands-on metallurgy depth, and erode brand margins.
The Fullion Advantage
Fullion was founded to resolve this friction. By combining international commercial transparency and English/Cantonese/Mandarin technical communication in Hong Kong with deep, multi-axis machining capabilities in Guangdong, we offer complete end-to-end production governance.
Every collection benefits from direct Design for Manufacturability (DFM) reviews, certified raw material lots, traceable cleanroom assembly, and strict non-disclosure protections from day one.
Manufacturing Scope
Specialized Production Divisions
Our cleanroom and CNC fabrication facilities deliver turn-key solutions across four specialized industrial categories.

Architectural & Lifestyle
Lifestyle & Decor Objects
Luxury stainless steel tableware, barware, solid brass incense burners, candle holders, and collectible metal figurines engineered for boutique luxury brands.
Engineering Methodology
Our Structured Manufacturing Protocol
We treat every product as a precision engineering endeavor. Every project follows an auditable 6-stage lifecycle to guarantee consistency from prototype to volume delivery.
STAGE 01
DFM Feasibility Analysis
Our senior tooling engineers review your CAD models, sketches, or physical reference parts to optimize wall thicknesses, parting lines, and tooling paths.
STAGE 02
2D Blueprint Master Packages
We generate comprehensive 2D manufacturing blueprints defining critical dimensional tolerances (down to ±0.003 mm), chamfers, and alloy certifications.
STAGE 03
First-Article Prototyping
Physical first-article prototypes are machined via 5-axis CNC and hand assembled in our cleanroom for client tactile and mechanical confirmation.
STAGE 04
Batch Machining & Finishing
Volume production incorporates multi-spindle CNC turning, investment casting, automated 8K mirror buffing, hairline brushing, and Class 10,000 PVD coating.
STAGE 05
Rigorous Metrology & Cleanroom QC
Completed pieces undergo 100% dimensional CMM scanning, optical projection, hydrostatic water pressure testing, and torque audits under AQL 1.0 standards.
STAGE 06
Global Export & Fulfillment
Finished components and timepieces are individually blister-packed in anti-static materials, packed in export grade cartons, and dispatched via express air courier.
Operating Principles
Guiding Engineering Values
The non-negotiable quality commitments that govern our workshop operations, client collaborations, and commercial policies.
PRINCIPLE 01
Engineering Clarity
Every product begins with documented technical specifications. We never cut corners on engineering blueprints, tolerance limits, or alloy verifications.
PRINCIPLE 02
Material Integrity
Surgical-grade 316L stainless steel, titanium, and bronze are our core foundations. We never compromise on material density or corrosion resistance.
PRINCIPLE 03
Brand Confidentiality
We work strictly for brand owners and design studios. Your proprietary molds, CAD drawings, and branding assets remain legally protected under bilateral NDAs.
PRINCIPLE 04
Long-Term Growth
We do not seek one-off transactional orders. We invest in tooling and manufacturing infrastructure that scales reliably as your brand collections expand.

Enterprise Inquiries
Frequently Asked Questions
Key insights into our manufacturing capabilities, prototyping models, intellectual property safeguards, and order progression.
Is Fullion a trading company or a direct manufacturer?
Fullion is a direct contract manufacturer. We operate our own precision machining, finishing, and cleanroom assembly bays in Guangdong under direct technical management, complemented by our commercial headquarters in Hong Kong. We do not broker orders to third-party factories.
Can you assist with products that only have rough concept sketches?
Yes. Our engineering department provides comprehensive Design for Manufacturability (DFM) assistance. We take initial sketches, dimensional moodboards, or physical references and develop production-grade 3D CAD models and 2D engineering blueprints.
What are your standard Minimum Order Quantities (MOQs)?
For complete custom watches, initial production runs typically start at 300 to 500 units per collection, which can be split across dial or finish variations. For individual watch components or custom lifestyle objects, MOQs range from 100 to 300 pieces depending on geometry.
How do you protect our brand design and intellectual property?
We execute binding bilateral Non-Disclosure Agreements before reviewing client drawings. Custom molds, stamping dies, and CAD blueprints are dedicated exclusively to your account and never shared or repurposed.
What are the typical lead times for prototypes and batch production?
First-article prototypes typically require 25 to 35 working days following blueprint approval. Mass production runs usually take 45 to 60 working days depending on surface treatments and caliber integration complexity.
