In 2026, international fast-fashion brands and supermarkets face significant logistical challenges. Fluctuating shipping costs, strict customs inspections, and complex international trade tariffs require brands to build highly resilient, risk-averse supply chains.
If a buyer relies on a manufacturer confined to a single geographic location, they expose their entire retail operation to massive geopolitical bottlenecks.
To provide our international B2B clients with unparalleled stability and highly competitive pricing, Zhantai Glasses actively operates a state-of-the-art Thailand factory alongside our Wenzhou headquarters. This dual-hub manufacturing strategy offers immense strategic advantages when you order anti blue light glasses wholesale:
The Bulk OEM/ODM Ordering Process: A Step-by-Step Guide
Executing a high-volume custom order requires a highly organized workflow to guarantee success and protect your retail profit margins. Here is the exact step-by-step roadmap you will experience when you initiate a bulk order with us.
Step 1: Design Consultation and Technical Specifications
The process begins with your brand’s specific vision. Your buying team provides reference concepts, target demographic data, and ideal retail price points to our engineering department. We lock in the technical specifications together. You decide whether to utilize a sleek transparent TR90 polymer, a high-gloss Tortoise PC finish, or a sleek metal frame. We ensure all external packaging and product descriptions use clean, consumer-facing language. Finally, we finalize the exact blue light blocking percentage your market requires.
Step 2: 3D CAD Modeling and Physical Prototyping
Our engineers generate precise 3D CAD models of your frame. After your team approves the digital files, the factory utilizes advanced CNC machining to produce a physical prototype. This crucial step allows your buyers to hold the product, test the ergonomic fit on a human face, and verify all visual proportions and lens coatings before committing to mass production.
Step 3: Mold Creation and The MOQ Standard
Upon your approval of the physical prototype, our engineers cut the heavy steel injection molds. Because designing and tooling these precision molds requires massive engineering labor and expensive machine time, mass production relies heavily on economies of scale.
To optimize the injection machines and deliver the lowest possible unit cost for our corporate clients, we operate with a strict Minimum Order Quantity (MOQ) of 1200 units per style. This volume guarantees production efficiency and ensures your brand achieves aggressive profit margins.
Step 4: High-Speed Mass Production and Assembly
With the steel molds locked into the injection machines, mass production officially begins. Technicians inject the molten polymers into the molds under extreme pressure. Once the raw frames cool, the finishing team meticulously polishes the plastic to achieve a perfect, high-end luster.
The assembly department then installs the durable metal hinges, secures the blue-light-blocking lenses into the front rims, and applies your custom brand logo to the temple arms using precision pad printing or laser engraving.
Step 5: Final Inspection and Freight Logistics
Before the factory boxes your bulk order, every single pair passes through a rigorous Quality Assurance checkpoint. Inspectors manually verify the hinge tension, check the lenses for microscopic scratches, and run random batch tests through the spectrophotometer to guarantee blue light filtration accuracy. Finally, the logistics team packages the glasses according to your exact retail specifications and arranges direct freight shipping from our Thailand or Wenzhou facilities directly to your international distribution centers.
