Step-by-Step Guide to Ordering Custom in Bulk
Embarking on a high-volume OEM (Original Equipment Manufacturer) or ODM (Original Design Manufacturer) project might seem daunting. However, a professional butterfly sunglasses manufacturer will streamline this process into a predictable, highly organized workflow.
Here is exactly what you can expect when you partner with us to bring your eyewear vision to life.
Step 1: Design Consultation and Specifications
The process begins with your vision. You share your reference images, sketches, or brand mood boards with our engineering team. We discuss your target demographic, your retail price point, and your specific material preferences—such as opting for a clear, high-gloss polymer or a matte-finish Tortoise design. During this phase, we also finalize the functional requirements, including the desired lens Visible Light Transmission (VLT) category and hinge type.
Step 2: 3D CAD Modeling and Prototyping
Once we lock in the specifications, our engineers create highly detailed 3D CAD (Computer-Aided Design) models of the frame. We send these digital files for your approval. After you approve the digital design, we use advanced 3D printing or CNC machining to create a physical prototype. This allows you to hold the glasses, test the fit on a real human face, and verify the proportions before we commit to mass production.
Step 3: Mold Creation and The MOQ Requirement
After you approve the physical prototype, we move to the most critical stage: cutting the steel injection molds. Because creating these precision molds requires significant engineering labor and machine time, mass production relies on economies of scale.
To maintain our highly competitive pricing and ensure production efficiency for our B2B clients, we operate with a strict Minimum Order Quantity (MOQ) of 1200 units per model. This volume allows us to optimize the injection machines and deliver the best possible unit price for your retail distribution.
Step 4: Mass Production and Assembly
With the molds secured in the injection machines, mass production begins. We melt the selected polymers and inject them into the molds under massive pressure. Once the raw frames cool, our technicians carefully polish the plastic to remove any seams or rough edges.
Next, the assembly team takes over. They install the metal hinges, secure the UV400 lenses into the oversized butterfly rims, and apply any custom brand logos to the temple arms via pad printing or laser engraving.
Step 5: Final Inspection and Global Shipping
Before we box your order, every single unit passes through our Quality Assurance department. Inspectors verify the hinge tension, check the lenses for scratches, and ensure the color matching aligns perfectly with your approved prototype. Finally, we package the sunglasses according to your retail requirements—whether that means individual polybags for warehouse storage or fully branded retail boxes—and arrange freight shipping from our manufacturing hubs directly to your distribution centers.
