A, QA test hardware operations must know handbag hardware accessories according to functional, safe sex two major premise.
Two, hardware problems poor plating, plating color, fade, scraping hands, opening and closing are not flexible, poor, signs of rust,
In three, the conventional inspection method and inspection tools.
Four, vernier caliper / torsion meter / gauge
1, hit nails: Volume nail surface diameter and length of screw angle respectively. The data is its specifications. Surface plating is bad, no rust phenomenon.
2, pull card D buckle or circle category: D buckle or circle diameter, volume after rail roughness, check the wire interface adaptation, whether scraping hands. Then the tensile test, shall not be less than 15LBS, handle D buckle and circle electroplating whether OK, pulling force shall not be less than 28-60KG, other ibid.
In 3, a pull piece torsion of conventional 3 around the rotating whether 2.5KG OK, 5 piece around the rotating 4KG, 8 piece around the rotating 6KG, 10 piece around the rotating 8KG.
In 4, dog buckle type test methods: electroplating whether OK, chromatic aberration, switch is flexible, scraping hands, amount of dog buckle diameter, roughness measuring wire. Then the tensile test, decorative dog buckle must bear no less than 8KG, usually 28-60KG
5, side buckle type, plating is uniform, scraping hands, measure its diameter, and then measure its wire width, must bear the 28-60KG tensile test.
In 6, the magnetic buckle type, plating is uniform, scraping hands, measure its diameter, gasket and ears of firmness, magnetic buckle opening must be able to withstand the porosity of not less than 2LBS, the tight not higher than 8LBS. The pressing buckle and so.
7, pin buckle, plating is uniform, scraping hands, pin length is OK, the amount of flexibility, the diameter and the diameter of wire. Pin buckle force shall not be less than 28KG.
In 8, lock type, surface plating is Yun uniform, bright. Edges and corners are scraping hands, inserting is flexible, the screw is matched. Lock plug mated, must bear the pulling force of not less than 18LBS.
In 9, the chain type, interface is fit, plating is uniform without signs of rust, whether scraping hands. Decorative chain must withstand the force shall not be less than 15LBS.
10, surface decoration drilling, electroplating surface is uniform, bright, Rhinestone is reflective, shedding, Rhinestone between location is uniform, with no signs of rust.
