OEM Sunglasses Manufacturing
Overall, the process of sunglasses manufacturing involves numerous steps., some of which can be automated with machinery, while others still require manual labor. The production process varies depending on the materials used. Here, we will use acetate sunglasses as an example to illustrate the entire manufacturing process. The production of acetate sunglasses involves several key steps: sunglasses designing, prototyping, material selection, frame carving, nose pads welding, needle thrusting, tumbling, and more.
Due to limited space, not all process steps will be involved, but this will not hinder your understanding of the production process.
Sunglasses Design and Prototyping
As we all know, before creating any product, it’s essential to clearly understand what we want to manufacture. The same principle applies to sunglasses manufacturing. Before the actual production phase begins, it’s crucial to communicate with the sunglasses manufacturer and finalize all design details. This initial stage sets the foundation for the entire production process. Click here to learn more about sunglasses design

The Process of Acetate Sunglasses Manufacturing
Acetate sunglasses manufacturing is a detailed and multi-step process that combines both automated and manual craftsmanship to ensure high-quality results. Here’s an overview of each stage involved in the production of acetate sunglasses, including what each step entails and its significance.
Drying Acetate
Acetate sheets are dried to remove any moisture content. Ensures the material is stable and ready for precise cutting and shaping, preventing warping or other issues during production.
Sawing Sheet
Acetate sheets are cut into manageable sizes. Prepares the material for detailed carving and shaping into frames.
Frame Carve
The cut acetate pieces are carved into the shape of the sunglasses frames. Defines the basic shape and structure of the sunglasses frames.
Nose Pads Welding
Nose pads are welded onto the frames. Ensures comfort and stability when wearing the sunglasses.
Needle Thrusting
Precision drilling to create holes for hinges and other components. Ensures accurate placement of hinges and screws for assembly.
Tumbling
Frames are polished using a tumbling process. Smooths and refines the surface of the frames for a high-quality finish.
Hinge Welding
Hinges are welded to the frames. Provides the sunglasses with durable and functional joints for folding.
Temple Cutting
Temples (arms of the sunglasses) are cut to the appropriate length and shape. Prepares the temples for attachment to the frames.
Screw Assemblying
Screws are assembled into the hinges and other components. Ensures all parts are securely connected and functional.
Temple Curving
Temples are curved to fit comfortably around the ears. Enhances the fit and comfort of the sunglasses.
Filing End Piece
The ends of the temples are filed and finished. Ensures smooth edges and a comfortable fit.
Groove Milling
Grooves are milled into the frames for lens placement. Prepares the frames to securely hold the lenses.
Polishing
Final polishing of the frames. Gives the frames a glossy, high-quality finish.
Lens Cutting
Lenses are cut to fit the frames precisely. Ensures lenses fit perfectly within the frame grooves.
Print the Customer’s Logo
The customer’s logo is printed onto the sunglasses. Personalizes the product and enhances brand identity.
Install Lens
Lenses are installed into the frames. Completes the assembly of the sunglasses.
Adjusting Frame
Frames are adjusted for final fit and alignment. Ensures the sunglasses are comfortable and properly aligned.
Quality Inspection
Final inspection of the sunglasses. Ensures all sunglasses meet quality standards before packaging.
Packaging and Shipment
Sunglasses are packaged and prepared for shipment. Protects the sunglasses during transport and ensures they arrive safely to the customer.
