  • The needle of a lock stitch sewing machine plays a crucial role in creating the stitch. The needle is responsible for piercing the fabric and creating a hole for the thread to pass through. The design of the needle is important as it determines the quality of the stitch.

  • Double needle sewing is an exquisite technique that elevates the quality and aesthetic appeal of various sewing projects. Utilizing two needles threaded with a single line of thread, this method creates parallel lines of stitching, which not only enhances the design but also adds strength and durability to the fabric. Whether applied in garment construction, home décor, or craft projects, double needle sewing brings a professional finish to any piece.


  • Additionally, overlock machines tend to have more stitch options and settings than sergers. They can create a variety of stitch widths, lengths, and styles to suit different sewing projects. Overlock machines also have differential feed mechanisms, which allow you to adjust the feed of the fabric through the machine for more precise stitching.

  • In addition to providing strength and durability, lockstitch sewing also helps to prevent leaks and spills

  • The dog cage is a resting place for the dog, do not put it in the place where the family is walking, teach the children, when the dog is in the cage, do not disturb the dog.
  • Most people think that the fine wire of the front and back twist barbed wire is not as thick and durable as common sense, but the front and back twist barbed wire is made of hot-dip galvanized steel wire, which is more than three times greater than the tensile strength of iron wire, and the amount of zinc added is not less than hot-dip wire
  • One: according to the color of the spray blade thorn rope, its price is higher than the ordinary blade thorn rope 2000-2200 yuan, but the price ratio of the spray blade thorn rope is much higher.

  • Large roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other surface treatment process processing. Large roll galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire). Although galvanized galvanized wire and silver powder paint spray effect appearance is not much different. But the effect is very different, galvanized wire surface is zinc layer, good adhesion, good corrosion resistance.

  • Large coils of galvanized wire are divided into hot dip galvanized and cold dip galvanized. Hot dip galvanized wire is dark in color, consumes more zinc metal, forms infiltration layer with the base metal, and has good corrosion resistance. Hot dip galvanized wire can be maintained for decades in outdoor environment. Cold galvanized production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

  • Annealed wire is a soft iron wire made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. The composition of iron wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet rolled into 6.5mm thick steel bar is the wire rod, and then put it into the wire drawing device into a different diameter of the line, and gradually reduce the aperture of the wire tray, cooling, annealing, plating and other processing technology made of various specifications of iron wire.

  • In addition, before the wire enters the zinc liquid, a layer of insulation material containing zinc oxide reducing agent can reduce the heat loss and zinc ash floating. When the zinc solution contains 0.002%-0.005% aluminum, the brightness of the zinc layer can be increased obviously, and excessive zinc ash can be prevented from oxidation on the surface of the zinc solution.

  • The purchase of blade barbed rope also needs to consider the higher manual installation cost in the later period. Generally, customers only ask the price of blade barbed rope, and sometimes the installation cost is not taken into account in the budget, which is very unreasonable. Because the installation cost is not cheaper than the rope itself, sometimes even the blade rope and column combined. The blade stabbing rope needs a lot of manpower and material resources for installation. In general, the installation cost is also a relatively large expenditure item in the stabbing rope project.
