Differences Between Straight and Curved Dispensing Needles——Considerations in Choosing Straight or Curved Needles

Accessibility of the Target Area The most obvious factor in choosing between straight and curved needles is the accessibility of the area where the fluid needs to be dispensed. If the target area is flat and easily reachable, a straight needle is usually the simplest and most efficient option. However, if there are obstacles, tight corners, or angled surfaces that need to be navigated, a curved needle becomes indispensable. For example, in the repair of small, intricate electronic devices, where components are packed closely together, a curved needle may be required to apply adhesive to a specific joint without touching adjacent components. Type of Fluid and Dispensing Requirements The nature of the fluid being dispensed also plays a role in the needle selection. Viscous fluids may require a larger - bore needle, and the choice between straight and curved will depend on the application area. For highly viscous adhesives used in heavy - duty industrial bonding, a straight needle with a larger inner diameter may be suitable for flat - surface applications, while a curved version of the same large - bore needle could be used if the bonding area is in a hard - to - reach location. Additionally, if the dispensing process requires a very precise and controlled flow, such as in the case of applying conductive adhesives in microelectronics, both straight and curved needles need to be selected based on their ability to deliver the fluid in the required amount and pattern. In conclusion, both straight and curved dispensing needles have their own strengths and are essential components in the field of dispensing technology. Understanding their differences in structure, function, and compatibility with dispensing syringes, especially in the context of American and Japanese styles, is crucial for achieving optimal results in various manufacturing and industrial applications. By carefully considering the accessibility of the target area and the type of fluid and dispensing requirements, manufacturers can make an informed decision on whether to use a straight or curved needle for their specific processes.

Advantages of Plastic Dispensing Valve

Advantages of Plastic Dispensing Valve Good chemical compatibility: plastic material has good chemical stability and can resist the chemical erosion of many kinds of glue. Like instant glue, epoxy resin glue, silicone, etc., in the process of using, plastic dispensing valve will not have chemical reaction with glue, will not contaminate the glue, to ensure the quality of dispensing and the performance of the glue itself. Light weight: Compared with metal dispensing valves, plastic dispensing valves are lighter in weight. This feature is an obvious advantage in automated dispensing equipment, can reduce the overall load on the equipment, so that the equipment movement is more flexible, reduce the energy consumption of the equipment operation, but also to facilitate the installation and commissioning of the equipment. Lower cost: the relatively low cost of plastic raw materials, and plastic is easy to mold, through injection molding and other processes can be mass production, can effectively reduce the manufacturing cost of dispensing valves, for the need to use a large number of dispensing valves for the enterprise, you can significantly reduce the cost of production, enhance economic efficiency. Good insulation: in the electronics industry and other insulation requirements of the field, the insulation properties of plastic dispensing valves can be avoided due to the conductive dispensing valves triggered by the circuit short-circuit and other issues, to protect the safety and stability of electronic products in the production process. Easy to customize: Plastic can be added through different additives or different molding processes to meet different performance requirements, to facilitate customized production according to specific dispensing application scenarios and requirements, such as changing the hardness of the plastic, toughness and so on.
