The measurement frame has a certain lens retention ability, ensuring that the frame can be safely worn for 2 years or more, preventing the lens from falling off due to a slight impact, affecting the wearing effect.
Glasses Frame Coating Adhesion Tester is important for ensuring that the coating on spectacle frames is applied properly and will not easily peel or flake off.
eyeglasses frame perspiration corrosion tester is designed to simulate the conditions that spectacle frames are subjected to in everyday use, such as perspiration and corrosion, in order to determine how well they will hold up over time.
Eyeglasses Frame Tensile Welding Tester Used for testing the tensile properties of eyeglass frames to determine the strength of welded or assembled connections.
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.
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.
eyeglass lens flame retardant tester to determine whether the material has the required flame retardant properties to ensure the safety of users.
wear test 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.
Eyeglasses Lens Impact Tester, Impact Testing Machine is mainly used to test the impact resistance of the lens, so as to prevent the lens from breaking or falling off due to some impact, thus endangering the safety of users.
