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.
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.
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.
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.
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.
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.
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.
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.
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.
