The Spectacle Frame Endurance Tester has a certain fatigue resistance, ensuring that the frame can be safely worn for 2 years or more, and the frame can be resisted from normal loss.
Eyeglass Hinge Cycle Tester to determine the spring hinge of the frame has a certain durability, Spectacle Hinge can withstand a certain number of opening and closing activities and maintain the original state, the purpose is to detect the change of the spring force of the spring hinge.
Digital Torsion Tester Machine Equipment For Glasses Leg upper part of this instrument is a sample clamp, and the glasses frame is clamped at both ends of the clamp for torsion test.
Eyeglass Falling Sand Abrasion Tester simulates the effects of falling sand on the lenses, which can scratch and damage them over time. This type of testing is important for ensuring that eyeglass lenses are able to withstand the rigors of everyday use and will not easily become scratched or damaged.
eyeglass lens flame retardant tester to determine whether the material has the required flame retardant properties to ensure the safety of users.
Eyeglasses Frame Tensile Welding Tester Used for testing the tensile properties of eyeglass frames to determine the strength of welded or assembled connections.
Eyeglass Nickel Release Tester In the process of nickel release test, it is necessary to use the roller to simulate the loss for about 5 hours to destroy the coating on the surface of the frame.
Eyeglass Expansion Durability Tester To determine the over-extend the temple arms of eyeglass with certain distance, which can withstand opening and closing angles at certain force values and repeatedly opening and closing, with the aim of detecting changes in temple arms life.
Eyeglasses Lens Wear Tester Equipment Used for testing the surface quality of the lens, it is required to rub the surface of the lens with steel wool or pencil according to relevant standards to observe the degree of friction resistance of the lens.
