A:

Combination pliers points on the general market and high grade two, the division of the so-called class not because of quality problems, and make the wire clamp is material problem, and the grade of the different. General wire pliers can be made of chromium vanadium steel high carbon steel and nodular cast iron. Chrome vanadium steel of high hardness, good quality, this kind of material is commonly used in manufacturing of steel wire can be classified as high grade steel wire cutters, the relative is lower level of high carbon steel, ductile iron do combination pliers quality most times, the cheapest price.

This store is located in the world's largest small commodities market - yiwu international trade city, zhejiang province, accompanied by the growth of the whole yiwu international trade city gradually set up a complete products production and sales of industrial chain, built up his own a well-known brand - sheng navigation hardware tools. The main sales wire pliers are professionally certified vanadium steel wire pliers. The surface can be plated with chromium, nickel iron, sublight, electroplating, black nickel and other treatments. Generally have inner box, elevator, card, double bubble, head bubble wrap. Durable, not easy to rust, variety, good quality. Products are sold all over the world. It is well received by domestic and foreign customers.

Use caution: use pliers to act according to your ability, not overload. Avoid by all means is not in the case of cut continuously twist pliers, easy to collapse teeth and damage of steel wire or iron wire or copper wire, as long as the claws can leave a bite, then use pliers mouth before the tooth clamping wire, gently up or down a wire, can break off the broken wire, not only save Labour, and no damage to pliers, can effectively extend the service life. In addition, the wire pliers are insulated and not insulated, and should be distinguished in the charge operation, so as not to be damaged by strong electricity!

Iv. Fabrication process

(1) steel forging.

(2) blank shaping (thickness repair) -- drilling center hole -- rough scraping (to make the coordination degree level)
(3) forming milling (milling back, teeth, circle, back teeth) -- fine scraping (smooth and flat size)
(4) two pieces to match -- the bevel (cutting edge) -- the edge of the knife -- the rivets.
(5) locksmith (the dislocation of the blade) -- grinding (grinding wheel riveting, grinding shape, grinding neck) -- the head eye.
(6) white whole (clamp handle flatness, rear opening size, mouth gap)
(7) heat treatment (HRC42)
(8) black integration (flexibility and swing)-- fine grinding (two sides)
(9) high frequency heat treatment at the edge (hrc48-50)
(10) polishing
(11) oil packaging.

(2) the clippers open Angle should not be less than 22 °
(3) the cheek should not have the card resistance phenomenon, and can shear 1.6mm hard steel wire.
(4) no obvious loosening of tail rubber sleeve.
(5) the surface electroplating layer cannot have obvious scratches.

Vii. Precautions

5. Can not be used as a hammer;
