Optimum Cartridge Pistons

Description

Key Points:-

• Cartridge pistons manufactured by Nordson EFD and molded from high-density polyethylene (HDPE).
• Engineered to prevent blow-by, fluid bypass, and leakage inside Nordson EFD cartridges.
• Features dual wiping edges that clean inner cartridge walls during travel to minimize fluid waste.
• Incorporates air-dissipating vent channels to purge entrapped air during filling.
• Includes blue-pigmented, looser-fit variants with smaller wipers tailored for high-viscosity pastes and gels.

Optimum® cartridge pistons are precision-molded from high-density polyethylene (HDPE) to deliver an exact, consistent seal inside Nordson EFD cartridges. Engine-fitted tolerances prevent blow-by, fluid bypass, and leakage during both high-volume filling and long-term storage. By establishing uniform surface contact along cartridge walls, these pistons enable smooth, unobstructed travel for highly predictable, repeatable fluid dispensing.

Designed for demanding fluid packaging and dispensing operations, Optimum pistons significantly optimize production workflow and process control. The integrated dual wiping edges clean the inner cartridge walls during travel, minimizing fluid waste, reducing residue build-up, and simplifying disposal compliance. For specialized high-viscosity applications, blue pistons feature a smaller leading-edge wiper—providing a tailored fit that prevents dripping or stringing while offering quick visual confirmation of piston depth.

Key Features & Technical Specifications

• Precision-Molded High-Density Polyethylene: Engineered to exact tolerances to eliminate blow-by, ensure total fluid containment, and maintain continuous, friction-minimized travel along cartridge walls during high-pressure dispensing operations.
• Integrated Air-Dissipating Vent Channels: Features specialized geometry that allows entrapped air to escape during the filling process, significantly reducing or eliminating time-consuming centrifuging steps.
• Dual Wiping Edge & High-Viscosity Options: Incorporates dual wiping edges to thoroughly clean cartridge interiors and maximize fluid yield, with blue-pigmented, looser-fit variants specifically optimized for seamless dispensing and visual tracking of heavy pastes and gels.
