  • In conclusion, long arm sewing machines represent a significant advancement in sewing technology, particularly for those who love quilting and crafting. With their large sewing areas, advanced features, and versatility, these machines make tackling big projects more manageable and enjoyable. They cater to both experienced quilters and those just starting, offering opportunities for growth and creativity in the craft. Whether for personal use or a business endeavor, investing in a long arm sewing machine can transform the sewing experience, making it efficient, fun, and fulfilling.


  • *Due to the higher pricing and an entirely different segment, I did not include any industrial models into this comparison, but in case your budget could extend to several thousand USD, go check it out. My favorite, Janome HD9 is a top-notch professional, industrial sewing machine. Hopefully soon, I'll create a comparison between that one and the corresponding Juki model that's been on my mind for years too.

  • Strength of galvanized wire: tensile strength is the great tensile stress that the material can withstand before tensile fracture; Yield strength has two indexes: upper yield and lower yield. It is a process in which the stress does not increase but the deformation continues to occur during the tensile process. When the force value drops for the first time, the major stress is the yield strength, and the yield strength must be less than the tensile strength.

  • In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

  • 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.

  • There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.

  • With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.

  • The basic requirements are the flatness of the net surface, hook mesh first after weaving, weaving process, rolling flowers can not turn, to adhere to smooth, can not present wire or turn flowers.
  • Hexagonal cage has a wide range of applications, with the progress of science and technology, has been extended to the major hydraulic engineering, civil engineering. Geotechnical engineering and other projects. In the hydraulic hexagonal cage in the river construction to reach the utility, that is appropriate and the use of hexagonal cage used to fill stone, fixed river, can avoid river erosion bring water and soil loss. In the civil engineering project, the hexagonal cage is considered appropriate and the use of similar particle size volume particle filling, cage between the formation of a mesh wall, which is the stone cage mesh retaining wall.taining wall.

  • The amount of zinc on the surface of high zinc barbed rope is about 5 times that of general zinc barbed rope, thus greatly prolonging the time of rust resistance. In the appearance of the two products are silver white and metal texture is better, for the distinction between the two products is more difficult to distinguish if it is a layman, but for long-term work of professionals can be separated from the two at a glance.

  • Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.

  • 4, safety, environmental protection, harmless to people (livestock), even if it does not intend to touch the guardrail will not hurt like steel, iron guardrail. Stainless steel wire mesh can be used as poultry cage, egg basket, channel fence, drain tank, porch guardrail, anti rat net, mechanical protective cover, livestock and plant fence, grid frame, etc.

  • Ordinary installation of blade thorn rope on the wall and the height of the wall in two meters up and down the general construction costs in a dozen yuan a meter, but if it is said that the height of the prison construction ordinary wall has reached four or five meters so that the construction cost of each meter is about 30 or 40 yuan, mainly because of high altitude operation risk degree is relatively large reason. The construction cost is different, but the price of blade thorn rope is the same, often the construction cost is higher than the product, which is the thorn rope factory recommends customers to use better quality blade thorn rope, which eliminates the cumbersome time and cost of subsequent demolition and installation.

  • Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.

  • The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.

  • Of course, the quality of any kind of product is also affected by the implementation of the specification of the manufacturer, if it is the welding screen manufacturers in the production of their own is not very high implementation of the specification, or in the production line of the procedure specification has declined, or there is no higher requirements on the production link.
