● Detection tool: digital caliper or micrometer.
● Indicate the code for inspection.
● the number of outlet slot 5 × 2, hanging hook 2.
● hole A is not roundness ≤ 0.30mm, both sides of the hobbing plane unevenness ≤ 0.30mm, no significant warping.
● hole hole anastomosis is not allowed to have a step, feel smooth and unimpeded.
● no residual shape or damage, color is no different normal
● finish up to ▽ 7 or more, but allow for harmless scars and miniatures.
● Metal-free impurities or other debris, containing metal, debris products, must be waste separation.
● no melting marks, no internal pores bright spot. There are stomatal highlights (excluding melting marks) products for foreign goods.
● no flash, burr and excess material. Key parts of the burr ≤ 0.05 mm.
● anti-pressure ≥ 25 kg / square centimeter, no damage.
● feel a strong elasticity, and not brittle.
● hardness, wear resistance are suitable for high-speed heavy-duty rotation.
● Selection of raw materials must meet the requirements of the EU ROHS directive, and has UL yellow card certification and fixed-point supply.
● heat distortion temperature ≥ 120 degrees Celsius, insulation resistance must be ≥ 1000M ohm, flame retardant UL94Vo level / 0.8-3.2mm.
● High voltage test 4KV (AC, DC) / 1 minute without breakdown. (Tester for the Changzhou Instrument Factory CY2674A type.)
● other structures should meet the transformer manufacturing process as the standard.
