Critical sealing component for injection nozzles that prevents material leakage and maintains pressure integrity during plastic injection molding processes.
A precision-engineered sealing element specifically designed for injection molding nozzles, creating a hermetic seal between the nozzle tip and mold sprue bushing. This component prevents molten plastic leakage, maintains consistent injection pressure, and ensures proper material flow during the injection phase of the molding cycle. The sealing gasket/O-ring withstands high temperatures (typically 200-300°C), high pressures (up to 200 MPa), and chemical exposure to various polymer materials.

Typically every 500,000 to 2,000,000 cycles depending on material, operating conditions, and maintenance. Regular inspection for compression set, cracking, or chemical degradation is recommended.
Common causes include excessive temperature beyond material limits, chemical incompatibility with specific polymers or additives, improper installation compression, contamination from degraded material, and mechanical damage during nozzle cleaning.
No, material selection must match specific operating conditions. FKM works for most applications up to 230°C, FFKM for higher temperatures and aggressive chemicals, while silicone offers better flexibility but lower chemical resistance.
