Below is AXXON GKG VERMES ANDA Dispensing Seals and Gaskets
Dispensing machine seals (commonly called dispensing machine seals or dispensing machine seals) are mainly used in dispensing equipment to ensure that the glue does not leak during the dispensing process, ensuring the dispensing accuracy and the normal operation of the equipment. Its main uses include:
1. Sealing function: prevent glue leakage and ensure that the glue is only released at the predetermined position during the dispensing process.
2. Protection function: protect the dispensing head and dispensing valve to prevent external contaminants from entering and extend the service life of the equipment.
3. Control function: help control the flow of glue and ensure accuracy during the dispensing process.
Common materials for dispensing machine seals
The material selection of dispensing machine seals is usually based on the properties of the dispensing liquid and the requirements of the working environment. Common materials include:
1. Polytetrafluoroethylene (PTFE: Strong chemical corrosion resistance, suitable for a variety of chemicals.
2. Silicone: High temperature resistance, good elasticity, suitable for occasions requiring high flexibility.
3. Fluororubber (FKM/Viton): High temperature resistance and good oil resistance, suitable for high temperature and oil environments.
4. EPDM (ethylene propylene diene monomer): Good heat resistance, ozone resistance, and aging resistance, suitable for high temperature and oxidative environments.
5. Polyurethane (PU): Good wear resistance, suitable for environments with greater wear.
Service life of dispenser seals
The service life of dispenser seals mainly depends on the use environment and the properties of the dispensed liquid. Generally, a pan seal made of high-quality materials can be used for thousands of hours or even longer. Specific
Service life is also affected by the following factors:
1. Operating frequency: Frequent use will accelerate the wear of the pan seal.
2. Operating temperature: Too high or too low temperature may affect the elasticity and durability of the pan seal.
3. Corrosiveness of dispensing liquid: Some highly corrosive liquids will accelerate the aging of the pan seal.
Temperature range of dispensing machine seals
The temperature range of dispensing machine seals of different materials is different. The following are the approximate temperature ranges of some common materials:
1. Polytetrafluoroethylene (PTFE): -200℃ to +260℃.
2. Silicone: -50℃ to +230℃.
3. Fluororubber (FKM/Viton): -20℃ to +200℃.
4. EPDM (ethylene propylene diene monomer rubber): -40℃ to +150℃.
5. Polyurethane (PU): -30℃ to +80℃.
According to the specific application requirements, choosing a dispensing machine seal of the appropriate material can effectively improve the performance and service life of the dispensing equipment.
