● 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≤0.20mm,both sides of the hobbing plane of the parallelism≤0.20mm,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 meet the transformer manufacturing process as the standard.

● Detection tool:digital caliper or micrometer.
● Mark the code according to the illustration.
● The number of outlet slots is 6 x 2.
● The irroundness of the inner hole K is less than 0.20mm,which is suitable for matching with the size of the inner shell D.
● No obvious steps are allowed at the anastomosis of the inner hole,and there is no obvious warping after the assembly of the two pieces,and the joint is≤0.20mm.
● The shape is not incomplete or damaged,allowing invalid defects at the anastomosis,and the color is normal.
● The finish should be at least 7,but harmless scars and microcosm are allowed.
● No metal impurities or other debris,products containing metal and debris must be isolated as waste products.
● No fusion marks,no internal porosity bright spots.Products with stomatal bright spots(without fusion marks)are used as equivalent foreign products.
● No flash,burr and excess material.Burrs in key parts≤0.05mm.
● Pressure resistance≥25 kg/cm2,not damaged.
● Feel strong elasticity,and not brittle.
● Selected raw materials must meet the requirements of the EU ROHS directive,and have UL yellow card certification and fixed supply.
● Thermal deformation temperature≥120 degrees Celsius,insulation resistance must be≥1000M ohms,flame retardant performance UL94Vo class/0.8-3.2mm.
● Other structures should conform to the transformer manufacturing process.
