● 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.
● Other structures should be consistent with the transformer manufacturing process as a standard.
