Our Factory
PART MACHINES WE HAVE
Temple Shooting
Machines
In order to make acetate temple be out of shrink and affect to wear, it is necessary to put core wire inside the actate temples. There is precise drilling and core wire installation, the frame and the temples are well connected, this is helpful to make the glasses more durable and reducing the risk of loosening. Core wire shooting process is one important production step for producing high-quality eyeglass for sure,
Our company produced lots of customized core wire for our korea customers, which request complicated core wire shooting skills, otherwise there are lots of problems among the whole production process.
Tumbling
Machines
The tumbling process in eyeglass manufacturing can enhances production efficiency. Through continuous operation with automated equipment, it reduces manual intervention time and errors. We are always looking for the way to reduce production cost without affect quality, our company has invested over USD 150,000 in research and development, continuously improving tumbling materials and machinery to reduce handmade polishing cost. Although we are not a large-scale factory, our company owns 40 TUMBLERS. Our mission is to maintain the unique charm of each eyeglass frame while ensuring its surface becomes smoother and more refined.
Laser Welding
Machines
Laser weldig can work on very small details, also it has better welding accuracy by comparing with regular welding technique. when customers provide some complex eyewear designs to us for working, we will consider laser welding for meeting customers' requirement. Normally we use it in situations where traditional welding machines cannot meet the welding requirements or do not achieve the same quality as laser welding. Previously, we don't make laser welding in our own workshop directly and mainly cooperate with other professional outsource department, but the quality was not stable and hard to meet our requirements. To maintain our high-quality standards, we purchased 2 laser welding machines to be operated by our internal staff.
Ti Welding
Machine
Normally we use Argon welding to produce Titanium material eyeglasses, this welding method guarantees high-quality finishes for eyeglass frames. Our company has been producing titanium frames for 15 years. Throughout the production process, we have maintained excellent control over cleanliness, welding accuracy, and welding production efficiency, providing a strong guarantee for the production of high-quality eyeglasses. Currently, we have 8 argon welding machines for titanium frame welding.

LAB TEST WE DO
Artificial Sweat Test
Artificial sweat testing is used to check the corrosion resistance and durability of eyewear materials. This test copy the composition of human sweat by putting the eyewear in an artificial sweat container under specific temperature and humidity conditions. Here is rough test method: the test material we use includes sodium chloride, urea, and lactic acid, set the pH of human sweat (usually between 4 and 6). The testing temperature is generally set between 30°C and 40°C, time last from 48 to 72 hours. After the test, the eyewear should show no significant corrosion, discoloration, or structural damage, ensuring its durability and safety in actual use. Our company's metal plating can usually pass 48H artificial sweat testing.
Polarization Test
A polarization tester is based on the optical principle of polarization phenomenon. It uses the characteristics of polarizer to separate and measure polarized light in different directions. In this way, we can see how the polarized sun lenses are placed in eyewear frame, and improve the visual clarity and comfort.
Here is rough test method: placing the polarized sun lenses in the tester, rotating the lenses, and adjusting the light source to measure their light transmittance and polarization angle. The polarization tester will show the intensity and direction of the light.
Testing standards request the polarized lenses' light transmittance to be set within a specific range, and the polarization angle should be kept within +/- 1°..
Welding Test
Normally lots of experienced production manager will check the welding strength by bending the frame through hands, however our company always apply scientific methods to check the welding strenght. The machine we use is welding tester, it is used to check the quality and strength of the welding points. Here is rough test method: Apply a force of 10 to 20 Newtons to the welded joints, repeatedly bending them at an angle of 30 to 45 degrees again and again to check cracks, fractures, or looseness. Standards require the testing equipment to precisely control the applied force and angle. Through this test, we can see the welding strength of each eyeglass frames, and make sure the eyeglasses be wear safely and stably during dairly life.
The Hinge Durability Test
The hinge durability test for eyeglass frames is used to check the long-term durability of hinges. Normally, we will open and close the hinges again and again to achieve the number of times an eyeglass hinge would be used in daily life, checking the looseness, breakage, or failure.
Here is rought test method: a force of 0.5 to 1.0 Newton-meters (Nm) is applied, open and close the hinge time by time at an angle of approximately 90 to 135 degrees. Generally, a minimum of 10,000 opening and closing times is required to pass the test. The screwless hinges produced by our company can endure up to 30,000 opening and closing cycles without showing any signs of looseness, breakage, or failure.
Drop Ball Test
Belive that all eyewear people know drop ball test, this drop ball test is used to check the impact resistance of sun lenses, make sure the sunglasses can be wear safely in daily use. Normallly we will drop a steel ball with specific weight from a fixed height, then the ball will strike the sun lens surface, like an accidental impacts. During this step, we will use a 16g steel ball and dropped from a height of 1.27 meters. When the sun lenses should not show any signs of cracking, or separation, and must maintain their optical performance and surface is well kept, then this test pass. Usually, USA Customs requires a drop ball test report for making customs clearance.
Eyewear Size Reading Test
The size reading test is used to check the lens dimensions, so the lens size can be produced according to design specifications, also it is easy for production department to evaluate if the size is workable to move forward. Before the test, our people will use one caliper to measure the lens width, height, and perimeter.The size measurement should be same as the requirements outlined in the CAD drawing, also the lens dimensions should meet CE standards and customer demands. Typically, the actual width of the frame should not exceed more than 5mm size tolerance, and the height of the frame should not exceed than 3mm. Through this test, the production of eyeglass lenses quality is ensured, consumers will feel it is very comfortable to wear frame that deepward produce.
Sunglasses Stress Test
The sun lens stress test is one part of international industry standards, For example, ISO 12312-1 and ANSI Z80.3, especially European customers focus on this kind of test much more, because it is necessary for us as factory to meet market and regulatory requirements, and enhancing customers' eyewear brand credibility. This test is used to make sure that the sun lens will not hurt people's eyes and make sure the wearing comfortability. Stress induced by compression is typically acceptable if located in the B zone; however, if in the A zone, special attention is needed to ensure no significant impact on optical performance.
