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.
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.
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.
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 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.
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 Foot Wire Frame Angle Tester Measuring the durability of the longitudinal force of the spring hinge of the mirror frame, and it can bear certain times of bending and keep the original state, so as to detect the change of the spring force of the spring hinge.
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.
Eyeglasses Frame Torsion Tester For Endurance Test clamp the eyeglass frame on both ends of the fixture for torsion test, observe the degree of wear and evaluate its folding resistance, and provide reference data for material selection.
