Fluids are dispensed for numerous applications such as bonding, gasketing, filling, lubricating, sealing and many other uses from different industries. All types of fluids are used, from the thinnest to the thickest, two-part combinations, those that change viscosity, to those that need light curing. Dispensing can be done in single pieces, batches, or for volume manufacturing with fully automated in-line systems. Controlling the fluid dispensing process has become more important than ever before. Full service solutions with products ranging from fluid dispensing systems for low to high viscosity liquids, fluid dispensing valves, dispensing controllers, plunger pumps for precise dispensing, hibar pumps for precise filling, consumable products such as industrial dispensing syringes and cartridges, dispensing needles, custom made needles, standard pressure tanks, custom made pressure tanks, stirrer units, liquid dispensing systems etc. have been offered by numerous companies.
However, some companies are still looking for more innovative and flexible products. Process parameters, fluids, and valves often have to be changed on the fly. Companies are beginning to pay increased attention to trends including sustainability, that is to say greener manufacturing, lower energy consumption, decreased use of hazardous solvents, and lower waste generation.
Precision fluid dispensing is the application of a fluid to a substrate in a precise, controlled, repeatable, and consistent manner, day after day, month after month, and year after year. This directly ties to the quality of the final product. The specific application will determine what type of dispensing equipment and what processes should be used. To date, companies that manufacture fluid dispensing system have developed high quality fluid dispenser systems to fit many adhesive dispensing applications.
Most of them offer a wide range of liquid dispensing systems to help you to dispense any fluid such as glue, thin solvents to thick silicones and brazing pastes quickly, accurately, and with no waste or hand fatigue. Also, they offer four types of fluid dispenser systems, barrel dispensing systems, cartridge dispensing systems, valve tank dispensing systems and tube pump dispensing systems to meet a wide variety of your production requirements.
Many companies have been designing fluid dispense valves that are reliable and provide excellent accuracy, repeatable dispensing and precision dispensing performance over a range of material viscosities, material pressures and shot sizes. Valves are selected based on factors such as fluid viscosity, fluid content and purpose that the valves will be used for. Most of the manufactured dispense valves include many enhancing features such as adjustable suck-back control and pinch type stroke adjustment that can be used with difficult materials.
Fluid dispensing has evolved to such an extent that it can perform the exact operation, with the specific tools needed, to fit each company’s process and product requirements. It can increase productivity, lower cost-of-ownership, improve quality and reliability, and reduce time-to-market. But to take advantage of these improvements, each application must be carefully evaluated to select the most appropriate dispensing solution. Dispensing needs should be viewed from a systems perspective rather than trying to cobble together various components to make them work.
