Glue Dispenser & Coating Machine Seals
Product Introduction
Glue Dispenser Seals are core sealing accessories for precision glue dispensing equipment, mainly applied to key components such as automatic glue dispensers, piezoelectric jet valves, screw valves and glue storage tanks, serving as high-precision sealing elements integrating dynamic and static sealing. Made of high-performance materials including modified PTFE, perfluoro rubber, silica gel, nitrile rubber and spring-energized seals, they are compatible with glue media of different viscosities and chemical properties such as epoxy resin, UV glue, silica gel, hot melt glue and AB glue.
Designed for the working conditions of high-frequency reciprocating movement, high-pressure glue injection and micro-precision glue output of dispensing equipment, these seals feature excellent wear resistance, high and low temperature resistance, and chemical corrosion resistance. The unique spring energy storage structure can automatically compensate for sealing surface wear and assembly eccentricity errors, effectively solving problems such as glue leakage, dripping and uneven glue breaking after long-term operation. With a low friction coefficient and long service life, they perfectly adapt to high-pressure, high-speed and high-precision industrial dispensing scenarios and make up for the shortcomings of traditional ordinary O-rings.
Characteristics
Wide temperature resistance range (-50℃~250℃), capable of withstanding high pressure up to 50MPa; wear and fatigue resistance, suitable for high-frequency continuous operation; glue corrosion resistance, no swelling, hardening or aging; adaptive wear compensation, zero leakage during long-term operation; low friction resistance to ensure stable micro-dispensing accuracy.
Application Fields
Widely used in 3C electronics, semiconductor packaging, precision hardware, automotive electronics, new energy, medical devices, optical instruments and other industries. Core scenarios include chip packaging dispensing, mobile phone accessory bonding, circuit board three-proof dispensing, sensor sealing dispensing, power battery potting, precision parts gluing, medical device bonding and sealing, covering all automated dispensing processes with strict requirements for high precision, no leakage and high stability.
Product Introduction
Coating Machine Seals are special sealing accessories customized for automatic coating machines and three-proof coating equipment, mainly installed on key sealing positions such as coating machine nozzles, spray guns, fluid conveying pipelines, pressure cavities and reciprocating transmission mechanisms. Coating equipment usually performs large-area, uniform thin-layer fluid coating operations, with media dominated by low-viscosity fluids such as three-proof paint, insulating paint, anti-corrosion coating agents and atomized coatings, which put forward extremely high requirements for the penetration resistance, anti-atomization leakage and solvent resistance of seals.
Made of high-density modified PTFE, fluororubber and imported composite polymer materials, these seals are optimized for the working conditions of continuous atomization spraying and uniform fluid conveying of coating equipment. They feature excellent solvent penetration resistance, atomization corrosion resistance and aging resistance, which can effectively prevent paint penetration, atomization air leakage and uneven coating thickness, ensure uniform and stable coating process, avoid paint waste and product defects, and adapt to long-term continuous automatic coating production.
Characteristics
Excellent solvent resistance and paint penetration resistance, compatible with various paints and three-proof paint fluids; anti-atomization leakage, avoiding spray virtual edges, missing coating and thickness deviation; resistant to long-term continuous operation, no aging, cracking or deformation; high sealing accuracy, suitable for thin-layer precision coating processes; high and low temperature resistance and wear resistance, adapting to high-intensity assembly line operation.
Application Fields
Mainly applied in electronic manufacturing, household appliances and electrical equipment, automobile industry, aerospace, industrial control equipment, communication equipment and other fields. Typical application scenarios include circuit board three-proof coating, PCB insulation protection coating, auto parts anti-corrosion coating, household appliance control board moisture-proof coating, industrial control equipment waterproof and anti-corrosion coating, and precision component protective coating, serving as core sealing consumables for automatic precision coating production lines.
