According to the mold assembly table, cleaned and qualified molds are combined in different ways with sealing rings or adhesive tapes, and a dust-free production workshop is used. The cleanliness must meet the quality requirements of water, oil, and dust free.
1. Filling
Inject raw materials that have reached a certain viscosity through the sealing ring manually or mechanically into the assembly mold, check the sealing performance of the sealing equipment, and ensure that the quality meets the requirements.
2. One-time curing
Send the filled mold to the curing furnace for heating, and heat different specifications of glasses according to different curing curves and control programs, resulting in different curing times.
3. Detachment
The semi-finished products after solidification in the production of glasses are made of glass molds on both sides and transparent resin glasses in the middle. Separate the produced glasses from the substrate, resulting in the birth of rough glasses.
4. Trimming and cleaning
After separating the rough glasses from the mold, they are polished. Due to the diameter of the rough glasses being about 4mm larger than the required glasses, the edges of the trimmed glasses are smooth, making it easy for later processing. After trimming the glasses, there are unreacted raw material monomers and powder under the grinding edge on the surface, and they are cleaned using an ultrasonic cleaning tank.
5. Secondary curing
The function of secondary curing in glasses production is to eliminate stress inside the glasses and repair the surface of the glasses, making the dents on the surface of the glasses smoother. Finally, the glasses after secondary curing are inspected and stored in the warehouse.
6. Hardening
Soaking, alkali treatment, surface soaking, alkali treatment, rinsing, water cutting, drying, cooling, soaking hardening, preparation for drying and other sequential hardening treatments are carried out. The hardening solution mainly forms a transparent film, increases the surface hardness of the glasses, and enhances the adhesion between the coating film and the substrate surface. Hardening inspection, curing. After passing the inspection, send the glasses into the oven for hardening and solidification.
7. Coating
Place the chuck filled with glasses into the coating machine for coating. The purpose of painting is to reduce the reflection of light, but it is impossible to avoid the reflection of light. There will always be residual colors on the surface of the glasses, which means that the coated glasses are radiation resistant, anti-static, scratch resistant, and pollution resistant, making it easier to clean.
