Material Selection
Generation 1
For Generation 1 dispensing syringes, common materials are used for their construction. The barrel is usually made of general - purpose plastics, such as standard polypropylene (PP). While this material is cost - effective, it may have limitations in terms of chemical resistance and durability. For example, when used with certain aggressive glues, the plastic barrel of Generation 1 syringes may be prone to swelling or corrosion over time, which can affect the accuracy of dispensing and the lifespan of the syringe. The plunger is also made of relatively basic materials, which may not provide the best sealing performance and smooth - movement characteristics.
Generation 2
Generation 2 dispensing syringes take a step forward in material selection. High - performance polymers are often used for the barrel. These materials offer better chemical resistance, ensuring that the syringe can withstand a wider range of glue types without being damaged. For example, some Generation 2 syringes use specialized polypropylene materials with enhanced chemical - resistant properties. In addition, the plunger in Generation 2 syringes may be made of materials with self - lubricating properties, which significantly improves the smoothness of the plunger movement during dispensing. This not only makes the dispensing process more stable but also helps in achieving more accurate dispensing amounts.
