Fischbach K11 LDPE Plunger for 310 mL Cartridges

Description

The Fischbach K11 plunger is an LDPE cartridge component for 310 mL packaging used with sealants and other viscous compounds. Its convex head helps reduce trapped air during plunger setting, while the flexible sealing lips maintain contact with the cartridge wall during storage and dispensing.

Designed for Cartridge Filling and Dispensing

The K11 is suited to automated and manual filling operations that need dependable mechanical handling. The convex face allows the plunger to enter the filled cartridge with less air trapped beneath it. An inward-slanted expanding ring increases the effective plunger diameter as pressure rises, helping the component follow the cartridge wall and push material forward.

That expanding action supports more complete emptying when the packaged compound is thick or the applicator produces high force. Flexible sealing lips also help the cartridge work with compressed-air application equipment by limiting bypass around the plunger. Mechanical and pneumatic dispensers can both be used when they are compatible with the cartridge, plunger, and material viscosity.

During setup, match the plunger to the correct 310 mL Fischbach cartridge and verify that filling equipment seats it squarely. Keep the sealing surfaces clean and protect the component from deformation before use. Filling pressure, headspace, storage conditions, and the packaged chemistry should be validated as a complete packaging system.

Its 6.6-gram LDPE construction keeps the component light while providing the flexibility needed for sealing and pressure-responsive expansion inside the cartridge.
