How to Choose Fully Automatic Dispensing Equipment? Industry Precision Requirements are the Key!
In high-end manufacturing sectors such as new energy, automotive, photovoltaics, and 3C electronics, the stability of the dispensing process directly impacts product sealing performance, structural strength, and even service life. As the core equipment for achieving this process, the selection of fully automatic dispensing equipment often perplexes enterprises—how to choose fully automatic dispensing equipment? The answer is actually not complicated: industry precision requirements are the key! Different industries and processes have significantly varying demands for dispensing precision. Choosing the right equipment can avoid sealing failures, material waste, or product rework caused by adhesive deviations. This is particularly evident in the solutions provided by professional manufacturers deeply rooted in the dispensing field, such as Centron.I. First, Clarify: How Much Do Precision Requirements Vary Across Industries?The first step in selecting fully automatic dispensing equipment is to "match the seat"—clarify the precision requirements of your specific industry, as demands for dispensing precision vary dramatically across different fields:Power Battery Industry: Precision sealing of battery components and thermal conductive dispensing for modules require extremely micro-volume precision control. For instance, Centron's Miflo screw metering system achieves a minimum discharge volume as low as 0.014ml and a metering accuracy of ±1%, perfectly adapting to the "micro and precise" requirements for dual-component dispensing in power batteries, avoiding waste from excess adhesive or protection insufficiency from insufficient adhesive .Automotive Industry: For structural adhesive and hemming adhesive application in welding processes, uniform adhesive volume at every point is crucial to avoid compromising body sealing performance. Centron's Puflo plunger metering system, with ±1% accuracy, meets this requirement. For glass dispensing in final assembly, which requires not only precision but also compatibility with high-viscosity glass adhesive, Centron's Enflo continuous metering system, paired with heating functions, maintains ±3% accuracy while ensuring adhesive viscosity stability through temperature control .Photovoltaic Industry: Frame dispensing requires balancing "precision" and "cycle time." Centron's HF pressure stabilization metering system, with ±3~5% accuracy, suits small to medium capacity needs, while the IPF servo metering system, with ±1~3% accuracy, meets high-precision demands. Both support "one-drag-one" or "one-drag-two" configurations, adapting to high-cycle production lines. Junction box potting requires precise metering of low-viscosity fluids. Centron's MF screw metering system offers repeatability accuracy of ±2%, ensuring consistent potting volume to avoid overflow or insufficient protection .3C Electronics Industry: Dispensing processes for LEDs and semiconductor chips demand extremely high micro-volume precision. Equipment like Centron's Miflo screw metering system, with a minimum discharge of 0.014ml and ±1% accuracy, is necessary to meet the precise needs for chip sealing and bonding .II. How to Choose Fully Automatic Dispensing Equipment? Focus on Three Core Precision Parameters!After clarifying industry precision requirements, the next step is to focus on the equipment's core parameters, which are key to determining suitability. How to choose? At least monitor these three parameters directly related to precision:
Metering Accuracy: The Core Determining Dispensing "Accuracy"Metering accuracy is the "soul" of fully automatic dispensing equipment, directly affecting the consistency of each dispensing volume. Among mainstream metering systems, Centron's Miflo screw metering and Puflo plunger metering both achieve ±1% accuracy, suitable for high-precision fields like power batteries, automotive welding, and 3C electronics. The Enflo continuous metering system offers ±3% accuracy, adapting to high-cycle scenarios like automotive final assembly and photovoltaic frame dispensing. The Cyflo gear metering system maintains precision even in high-viscosity scenarios (20,000~3,000,000 cP), suitable for automotive coating and photovoltaic frame dispensing. When selecting equipment, ensure the metering accuracy is lower than or equal to the allowable deviation in industry requirements to prevent increased product defect rates .
Compatible Viscosity Range: Determines Whether Materials Can Be "Stably Delivered"Dispensing materials vary greatly in viscosity across industries. For example, thermal conductive adhesives in power batteries and glass adhesives in automotive applications can reach several hundred thousand cP, while some dispensing materials in 3C electronics have lower viscosity. If the equipment's compatible viscosity range does not cover your materials, it may lead to unstable delivery, adhesive volume fluctuations, or even breakage and sagging issues. Centron's feeding system can handle medium to high viscosity materials ≥20,000 cP, and the Cyflo gear metering system adapts to high-viscosity fluids from 20,000 to 3,000,000 cP. The transfer system can pre-treat high-viscosity materials through stirring or heating, ensuring stable delivery. When selecting equipment, confirm that the viscosity compatibility range includes your material's viscosity to avoid "underpowering" or "overkill" .
Control System Response: Determines Precision "Stability"Even if metering accuracy and viscosity compatibility meet standards, a slow control system response can cause precision fluctuations. Centron's CS2000 series control system has a program scan cycle as low as 1ms, enabling quick response to dispensing parameter adjustments and reducing adhesive pattern fluctuations. It also supports storing 255 independent recipes, allowing quick adaptation to different product dispensing parameters for multi-variety, small-batch production without frequent hardware adjustments, indirectly ensuring precision stability. Furthermore, some control systems feature adaptive control functions that self-learn from adhesive viscosity changes and adjust metering parameters in real-time. Centron's control system possesses this capability, further ensuring precision consistency in long-term production .
So, how to choose fully automatic dispensing equipment? First, check if the metering accuracy matches industry needs, then see if the viscosity compatibility range covers your materials, and finally, ensure the control system can guarantee long-term precision stability. These three points are indispensable.III. Don't Overlook: The "Hidden Guarantees" for Precision Implementation – Customization and ServiceWhen selecting fully automatic dispensing equipment, don't just look at "hard parameters"; also pay attention to the "hidden guarantees" that enable precision "landing"—customized solutions and service support. Otherwise, the equipment might not integrate well after purchase:
Customized Solutions: "Precise Adaptation" Tailored to Industry ProcessesDifferent industries have specific dispensing process characteristics, and generic equipment may not fully meet needs. For example, for photovoltaic frame dispensing, Centron provides a "one-drag-two" configuration where a single metering unit serves two dispensing stations, improving equipment utilization while ensuring precision in high-cycle production. For automotive glass dispensing, Centron designs an 8-section heating system (2 sections each for feeding, metering, hoses, and dispense valve) with PID precise temperature control to maintain adhesive viscosity and avoid temperature fluctuations affecting dispensing accuracy. For power battery dispensing, a dual-component dual-pump switching system enables non-stop production while ensuring metering accuracy . How to choose? Beyond core precision parameters, consider whether the manufacturer can provide customized solutions tailored to industry processes to avoid disconnection between equipment and production needs.
Service Support: "Precision Continuity" by Reducing DowntimeDuring long-term operation, equipment precision may decline due to component wear or parameter drift. Timely service support is then crucial. Centron has built a global service network, with 12 domestic service stations in China covering key cities like Shanghai, Shenzhen, and Changchun, and overseas service stations in Italy and Thailand with a spare parts warehouse in Hungary. Within the warranty period, it offers telephone technical support within 2 hours and on-site engineer service within 24 hours, enabling quick fault resolution, reducing unplanned downtime, and ensuring precision stability . When selecting equipment, pay attention to the manufacturer's service network coverage and response efficiency to avoid prolonged precision issues due to delayed service.
IV. With Precision as the Core, Choose the Right Equipment to Avoid DetoursIn the selection of fully automatic dispensing equipment, industry precision requirements remain the core benchmark throughout the process. From micro-dispensing in power batteries to high-cycle dispensing in automotive vehicles, from sealing dispensing for photovoltaic modules to precision dot dispensing in 3C electronics, precision demands in different scenarios determine the equipment selection direction.How to choose fully automatic dispensing equipment? Remember this core logic: anchor on industry precision requirements, first clarify your required precision range and material characteristics, then match the equipment's core parameters—metering accuracy, viscosity compatibility range, and control system response speed. Simultaneously, evaluate the manufacturer's customization capability and service support to ensure the equipment can both "meet precision standards" and remain "stable long-term." Manufacturers like Centron, with 18 years of deep experience in the dispensing field, have provided reliable equipment solutions for many leading enterprises by precisely matching the precision needs of different industries. This serves as an important reference for enterprise selection—choosing the right equipment not only improves dispensing quality but also reduces costs, enhances production efficiency, and adds advantages in high-end manufacturing competition.
