Whether you are a seasoned professional or a sewing enthusiast, embracing this machine can elevate your sewing experience to new heights.


  • In conclusion, the zigzag embroidery machine represents a significant advancement in the world of textile art. Its versatility, ease of use, and ability to produce high-quality designs have made it an invaluable tool for both amateur crafters and professional businesses. As the demand for custom embroidery continues to rise, these machines will undoubtedly play a pivotal role in the evolution of embroidery techniques. Whether you are looking to start a new hobby or enhance your business, investing in a zigzag embroidery machine might just be the key to unlocking endless creative possibilities in the realm of embroidery.


  • One of the primary benefits of using a long arm zig zag sewing machine is the efficiency it offers. The extended throat space enables sewists to work on larger projects without the frustration of fabric bunching. This feature is especially beneficial when quilting, where maintaining fabric integrity is crucial for achieving beautiful patterns. The zig zag functionality further enhances this efficiency. Zig zag stitches not only add decorative elements but also offer strength to seams, particularly in stretch fabrics. This dual capability allows users to explore a broader range of sewing projects, transforming an ordinary sewing experience into a creative adventure.

  • The specific design and layout principles are:

  • In the process of production, the acid activation solution can remove the corrosion products and oxide film on the surface of low carbon steel wire without excessive corrosion on the matrix. Galvanized wire can be used zincate galvanized or chloride galvanized process, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well.

  • Steel mesh manual binding line of the joint simple sliding, steel and concrete strength is weak, simple crack. The welded joint can accept not only pressure but also shear force. Longitudinal and transverse steel bars form a network structure, which plays a bonding anchorage effect. The number of solder joints per unit area is added when the diameter of the wire mesh is small and closely spaced. More conducive to strengthening the crack resistance of concrete, can reduce more than 75 percent of the attack of steel mesh cracks is a new, energy-efficient steel mesh structure, used in beams and columns, floors, roofs, walls, concrete pavement, bridge deck paving and other industrial and civil buildings.

  • 1, galvanized silk mesh molding sheet must be packed with flat hard materials, to avoid improper packaging and eternal deformation. It is important that each package and roll of raw material be marked with product name, standard, quantity, trademark, lot number, manufacturer, date of production, packing symbol, inspector code and inspection certificate.

  • Small and medium-sized cat cage, dog cage and fence are mostly pure wire welding, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage has to withstand more force.

  • In reinforced concrete structure, the crack width of cold wire drawing is smaller than that of circular steel bar or even that of hot rolled thread bar. So cold wire drawing is more popular in the construction industry. The material for cold drawing is made of steel bars and can be simply explained how it is made, that is, its production process is simple. It’s based on steel bars, which are constantly stretched evenly, stretching the bars into something very thin, like wire drawing, without plasticity.

  • All can do spring can be called spring steel wire, and high carbon is the highest carbon content. Features: WITH high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is OK, but welding function and cold plastic deformation ability is poor.

  • Galvanized hexagonal mesh uses: building wall fixed, heat preservation, heat insulation; Power plant piping, boiler heating; Anti-freezing, residential protection, landscaping protection; Raise chicken and duck, isolate chicken and duck house, play the role of protecting poultry; Protect and support seawalls, hillsides, roads and Bridges and other waterworks.

  • Hot dip galvanized steel wire surface smooth, smooth, no cracks, joints, thorns, scars and corrosion, galvanized layer uniform, strong adhesion, corrosion resistance lasting, toughness and elasticity is excellent. The tensile strength should be between 900Mpa-2200Mpa (wire diameter Φ0.2mm-Φ4.4mm). The number of torsion (Φ0.5mm) in more than 20 times, repeated bending should be more than 13 times. The thickness of galvanizing is thin, usually only 3-15 microns, bright, smooth, beautiful appearance, poor corrosion resistance, generally a few months will rust.

  • Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.

  • Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.

  • Annealing wire is widely used because it has a good elasticity and flexibility, in the annealing process can be good control of its hardness, it is mainly made of iron wire, more often used in the construction industry binding wire use. In the production of the wire factory, annealing wire will be processed according to the properties of the material, according to the needs of different to change its hardness degree, can make it has more advantages, can reduce the consumption of metal, reduce the cost of production.

  • U nail price selection of galvanized iron wire, hot dip galvanized iron wire and black iron wire and other high-quality wire, welded, PVC or PE, PP powder after curing coated its surface, with strong adhesion, good corrosion resistance, bright color and so on.

  • Galvanized iron wire can be divided into hot-dip galvanized iron wire and cold galvanized iron wire according to different processing methods. Galvanized iron wire is more prominent in its corrosion resistance. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Galvanized iron wire products are widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.

  • Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.

  • The blade gill net has 3-7 buckles every 2 turns, and it is a circle card. After being opened, it forms a spiral shape. When stretching, you must take protective gloves to prevent scratches. When opening, only one side of the gill net needs to be fixed, and then the gill net needs to be opened in the opposite direction. Pay attention to the spacing of the holes should not be too large, otherwise it will affect the aesthetic effect. As long as the time to slowly return to the line, simple operation, convenient construction.

  • The main factors causing metal rust: relative humidity of the atmosphere at the same temperature, the percentage of water vapor content and water vapor saturation content in the atmosphere, known as relative humidity. Under certain relative humidity, the corrosion rate of metal antirust oil is very small, but higher than the relative humidity, the corrosion rate increases suddenly. This relative humidity is called the critical humidity. When the humidity in the atmosphere is higher than the critical humidity, the metal surface will appear water film or water droplets, if the atmosphere contains harmful impurities, dissolved in the water film, water droplets, electrolytes and aggravate corrosion.
