In the manufacturing of core components such as filters and filter elements, the end cap gluing process directly affects the product’s sealing performance and durability. Based on practical production experience, the key points of end cap gluing operations are sorted out from three dimensions: equipment selection, process matching, and process control.
1. Process Matching: The “Two-Way Fit” Between Adhesive and Equipment
The performance of the adhesive is the underlying logic for gluing quality. Take the Filter end cover gluing machine as an example. Although PU adhesive is a conventional choice, it is prone to softening under high-temperature conditions of metal end caps, requiring a switch to two-component epoxy adhesive. On the equipment side, the glue injection pressure and speed need to be adjusted according to the adhesive viscosity to avoid needle blockage due to overly thick glue or glue seepage due to overly thin consistency. Factory technicians once found through experiments that reducing the rotation speed of the Double head end cap gluing machine by 15% can significantly improve the fluidity of high-viscosity adhesives.
The Filter element gluing machine must also consider the air permeability of the filter media. Excessive glue may block the pores of the filter element, while insufficient glue may lead to sealing failure. It is recommended to implement hierarchical management of equipment parameters, preset gluing quantity thresholds for different filter media, and equip online glue quantity monitoring modules.
2. Process Control of Filter Element Gluing Machine
Positioning deviation of end caps is a common cause of poor gluing. The error of traditional manual alignment can reach ±0.5mm, while the Filter element gluing machine with a visual positioning system can control the error within ±0.1mm. A certain enterprise improved the pass rate of Filter element gluing machine operations to 99.2% by adding an end cap incoming material inspection station.
The impact of environmental temperature and humidity on the adhesive curing speed cannot be ignored. It is recommended to equip the Double head end cap gluing machine with temperature and humidity compensation algorithms. When the workshop temperature exceeds 30°C, the equipment automatically shortens the glue injection interval to prevent the glue joint from entering the next process before curing.
Equipment maintenance is crucial to ensure stability. The glue path system of the Filter gasket pouring machine needs to be cleaned daily to avoid residual glue curing; the synchronous belt of the Double head end cap gluing machine needs to have its tension checked every 500 hours to prevent displacement of the glue injection head.
3. Quality Traceability of Filter Gasket Pouring Machine
Modern End cap gluing machines already have the function of uploading production data to the cloud. By scanning the QR code on the end cap, parameters such as glue injection pressure and environmental temperature and humidity of each equipment batch can be traced. When batch bubble problems occur in the Filter gasket pouring machine, the technical team can quickly locate abnormal adhesive batches through data review, avoiding broader quality risks.
End cap gluing operations represent a dual game between details and equipment. From the precise debugging of the Filter end cover gluing machine to the process adaptation of the Filter element gluing machine, every link tests the fine-grained control capabilities of the production team.
