Following on from our Tie Factory Visit, the next stop was our Sunglasses Factory. Our aim was to check the production facilities of the factory; to learn more about the production process and to make sure that the production goes smoothly. Production Management and Factory Visits go hand in hand, making sure production runs smoothly without hiccups is important and being in the factory allows for immediate feedback.
Sunglasses Factory Visit: Creating the Frames
The very first step when manufacturing sunglasses is deciding on your style. There are a huge range of styles for sunglasses and each style has an individual mold.
When you have decided on your style, the decided mold is put into an Injection Molding machine. The raw plastic material is added and will be molded to the decided style. It is at this stage that paint can be added to the raw material mix to give the sunglasses their intended colour or pantone match. The colour will run through the whole frame.
When the injection is complete, each frame is dropped into water to cool and retain shape. The injection process will continue until the allocated amount of frames have been created.
Although the frames have been made, we need to separate the arms from the overall plastic cast the mould injection has created. This is done by hand with the finished frames moved on to the next process where any bumps or imperfections can be smoothed out.
In this polishing stage, the frames are spun and smoothed using stones to remove any imperfections or bumps that have developed during the molding process. Now, the frames are a step closer to becoming promotional sunglasses.
Sunglasses Factory Visit: Assembling the Sunglasses
Now we have our completed frames, it is time to assemble and finish the sunglasses. This involves the attaching the metal part to the frames as well as branding the information along the arm.
Our supplier sources lenses from an external factory and these are sent out to be assembled at our factory. The plastic frames are constructed to hold the lenses in place using tension mount designs. In this type of frame, the lenses can be pressed into their respective openings through the front edge of the frame without falling out its rear edge. The plastic frame material permits sufficient stretching to allow the lenses to snap into these grooves, without snapping themselves.
Sunglasses Factory Visit: Packaging and Finalizing
The final step in the production process of promotional sunglasses is packaging. How will you be presenting your sunglasses? In a opp bag or in a paper box? Once the packaging has been completed, all is left is a QC of your products and the production process for sunglasses is complete.
