What Is the Purpose of Carbide Rods?

Carbide rods are cemented carbide round rods, also called cemented carbide bars, which are simply tungsten steel round rods or carbide rods. Carbide rod is a composite material composed of refractory metal compound (hard phase) and binder metal (bonding phase) produced by powder metallurgy.

Carbide rods are mainly used for drills, end mills, and reamers. It can also be used for cutting, stamping, and measuring tools. It is used in papermaking, packaging, printing, and non-ferrous metal processing industries. In addition, it is also widely used to process high-speed steel tools, tungsten carbide milling cutters, tungsten carbide cutters, NAS cutting tools, aviation tools, tungsten carbide drill bits, milling cutter core bits, high-speed steel, tapered milling cutters, metric milling cutters, micro end milling cutter, reaming pilot, electronic cutter, step drill, metal cutting saw, double-guaranteed gold drill, gun barrel, angle cutter, tungsten carbide rotary file, tungsten carbide cutter, etc.

Solid Carbide rods can be used not only for cutting and drilling tools (such as micron, twisted drills, drill vertical mining tool specifications) but also for input needles, various roll wore parts, and structural materials. In addition, it can be used in many fields, such as machinery, chemical, petroleum, metallurgy, electronics, and defense industries.

Selecting a solder ball jet nozzle

Jet (or Wave) soldering is similar to wave in that it’s uni-directional and provides the same benefits as wave. Its smallest solder diameter is 4mm, it requires minimal maintenance, and it is fairly low cost. The solder ball jet nozzle type you use will depend on the make-up of the board and the location of SMDs on that board.

For instance, a fairly large row of connectors/leads not in close proximity to SMD components could use a wide solder ball jet nozzle to swipe (or wave) the entire row at once. A small area closed situated to an SMD would require a very small solder ball jet nozzle to avoid disturbing the surface mount device.

Solder ball jet nozzles attack the board at about the same angle (7) as a Wave machine, and can deliver a high volume of solder using a tapered tip which guides solder roll-off in one direction returning unused solder back to the pot from its trailing edge. In this scenario, the direction of travel (board or nozzle) is very important.

Solder ball jet nozzles are long-lasting and usually cost only a few hundred dollars. Some boards can benefit from a custom solder ball jet nozzle to solder an area as quickly as possible in a dip or drag process, or even a min-wave.

Solder Ball Jet Nozzle Design

Most lab-based electrospinning setups comprises of a solder ball jet nozzle for dispensing of the solution. Despite the emergence of solder ball jet nozzle-less electrospinning techniques especially in mass production electrospinning, nozzle-based electrospinning still retains some advantages such as better charge concentration and solder ball jet nozzle variations for improving electrospinning or fabricating hybrid fibers.

In most lab-based electrospinning setup, a hypodermic needle with a flat tip is used as the electrospinning solder ball jet nozzle. However, electrospinning may still proceed with other needle tip configurations. A flat tip is generally preferred as it provides a flat surface for the formation of a stable Taylor cone with little oscillation of the jet compared to chamfered tip needle [Ksapabutr et al 2005]. At higher feed-rate, it was found that a flat tip needle is more prone to generating multiple electrospinning jets compared to chamfered tip needle [Ksapabutr et al 2005]. Parameters such as solder ball jet nozzle diameter has been covered elsewhere and will not be covered here. Instead, other improvements and variations of nozzle design shall be discussed.

As a class, the coaxial solder ball jet nozzle is the most widely used design in electrospinning. While most commonly used for spinning core-shell nanofibers through injection of different solution through the core and shell of the solder ball jet nozzle, this design have also been used to inject solvent through the shell cavity to maintain spinnability of the solution (Read more).

Injection of solvent through the shell of a co-axial electrospinning setup was also found to affect the cross-sectional profile of the resultant fibers. When electrospinning Eudragit L100 nanofibers using conventional single solder ball jet nozzle, the fibers produced were found to have a flat/ribbon cross-sectional profile. This is attributed to the formation of a thin wall/skin due to rapid evaporation of ethanol on the surface of the electrospinning jet. Subsequent evaporation from the core of the electrospinning jet causes the thin wall to collapse and form flat fibers.

To produce round fibers, Yu et al (2014) injected solvent through the shell of a co-axial solder ball jet nozzle during electrospinning such that it delays the evaporation from the surface of the main electrospinning jet which allows smoother mass transfer of the solvents from the core to the atmosphere. This delay also enables more stretching of the electrospinning jet and thus smaller diameter fibers can be produced. Another use of the coaxial design is to allow incorporation of air jet surrounding the core spinning solder ball jet nozzle to facilitate and improve jet initiation.
