How to make plastic eyewear1: Design of plastic eyewear.

The design of plastic eyewear can choose different colors and appearances according to the brand elements, applicable occasions, seasons and applicable people, showing individual style. Innovative frame shape design, such as square, round or special shape, can also make the glasses more eye-catching. In addition, the current environmental awareness is getting stronger and stronger. Using environmentally friendly materials to make glasses frames can reduce the consumption of natural resources and avoid pollution to the environment.

How to make plastic eyewear 2: Material preparation.

The main material for producing injection molded glasses frames is plastic particles, and different styles of glasses frames use different plastic particles. Before production, first select the appropriate plastic particles according to the requirements of the injection molded glasses frames, and then screen, clean and dry the plastic particles to ensure the stability and reliability of the particle quality.

How to make plastic eyewear 3: Making molds.

Mold design is one of the most critical links in the manufacture of plastic eyewear. When designing the mold, factors such as the shape, size, appearance and interface accuracy of the glasses frame need to be considered to ensure that the glasses frame manufactured by the mold can meet the needs of customers. For example, some of our customers have high requirements for the quality of glasses, so when we make the mold, we also need to mirror the inside of the mold to ensure that the plastic eyewear produced have a perfect appearance.

How to make plastic eyewear 4: Injection molding.

Injection molding refers to the process of pouring plastic into an injection molding machine and then making a certain shape through operations such as melting, pressurizing, injecting, cooling, and disengaging. Its main steps are as follows:

A. Material melting: Put the pre-treated plastic particles into the hopper of the injection molding machine and melt the plastic by heating.

B Plastic injection mold: When the molten plastic reaches a certain pressure and temperature, the plastic is injected into the pre-designed mold through the injection molding machine.

C. Mold cooling: After the injection molding is completed, the glasses frame in the mold needs to be cooled to ensure that it is completely hardened and demolded.

D. Product removal: The glasses frame manufactured in the mold is taken out of the mold by mechanical or pneumatic means.

How to make plastic eyewear 5: Manual process.

After completing the injection molding process of plastic eyewear, the glasses frame needs to be manually processed later, including repairing the discharge port, rollers, grinding, assembly and spraying.

How to make plastic eyewear 6: Quality control.

The produced glasses frames need to be quality tested to ensure that they meet the design requirements and customer needs. Among them, they mainly include appearance inspection, dimensional accuracy, durability, toughness and other aspects. For unqualified products, they need to be repaired or remanufactured in time.

plastic eyewear are a high-precision, high-quality manufacturing process from design, material preparation, injection molding, manual processing to quality control in every link. It requires strict control of the entire production process and handling of every detail. Only through professional production technology and quality assurance system can the produced glasses frames be guaranteed to be of high quality, beautiful appearance and durability. As an experienced injection molding glasses factory, BESTSEA makes plastic glasses for some mid-to-high-end European and American glasses brands, including plastic optical glasses and plastic sunglasses.
