N8 Nickel Chromium Alloy Wire/ Flat Wire 0.15mm*1.5mm for Industry Sealing Machine
1. General Description
Nichrome 80 (Nickel 80%, Chromium 20%) resistance alloy is an ideal electrical heating material that can be used up to 2150oF or 1200oC. It has suitable hot strength and extremely high electrical resistance. Nichrome 80 alloy (Strip and Wire) produces a strong chromium oxide layer upon heating that provides outstanding oxidation resistance at the elevated temperatures. It has high melting temperature about 1350oC. Nichrome wire offers a special resistance range of 5500 ohm/m.
We offer fine gauge wire for a broad range of applications including low temperature heating in the electronic equipments such as variable frequency controller for example potentiometers, pressure transducers, detonators, ceramic resistance, wire wound resistance, lead wire and also strings for musical instruments.
Nichrome 80 resistance heating alloy is suitable for reconstructing your atomizer and is particularly excellent for sub-ohm coils. It has smaller resistance per unit length than Kanthal hence it heats up more quickly and is recommended over Kanthal for various applications.
2. Sealing Machine
A vertical form fill sealing machine is a type of automated assembly-line product packaging system, commonly used in the packaging industry for food, and a wide variety of other products. Walter Zwoyer, the inventor of the technology, patented his idea for the VFFS machine in 1936 while working with the Henry Heide Candy Company. The machine constructs plastic bags out of a flat roll of film, while simultaneously filling the bags with product and sealing the filled bags. Both solids and liquids can be bagged using this packaging system.
The typical machine is loaded with a continuous flat roll of plastic film, which has had labeling and artwork applied to the exterior or interior of the film. Note that while plastic is the most commonly used packaging material in the food industry, the technology can also be used to form continuous metalized foil/film, paper, and fabric product containers by changing the edge sealing/seaming methods. For some products the film may first be fed through a sterilizing chemical bath and dryer prior to use in the packaging system.
For a vertical form-fill-seal the film approaches the back of a long hollow conical tube, which is called the forming tube. When the center of the plastic is near the tube, the outer edges of the film form flaps that wrap around the conical forming tube. The film is pulled downward around the outside of the tube and a vertical heat-sealing bar clamps onto the edges of the film to create the "fin Seal", bonding the film by melting the seam edges together.
To start the bagging process, a horizontal sealing bar creates the "Bottom Seal" by clamping across the bottom edge of the tube, bonding the film together, and cutting off any film below. This sealing bar can be on a fixed height, which is called an intermittent sealing process. Faster systems include a sealing bar that moves down with the bag while sealing. This is called a continuous process. The product is either pre-measured by a multi-head weighing system or the sealed tube end is then lowered onto a precision weighing table and the product to be bagged is dispensed through the long conical tube in the center of the bag. When the gross weight of the product-filled bag is reached, filling stops, and the horizontal sealing bar seals the top of the bag, simultaneously forming the bottom of the next bag above. This bag is then cut off from the tube and is now a sealed package, ready to advance onward into the product boxing and shipping processes.
