Ratio-Pak Accessories / Piston Insertion Tool - 200ml-400ml barrels

Product Name

Nordson Ratio-Pak Configurable Accessories / Piston Insertion Tool - 200ml-400ml Barrels

Brief Description

A specialized accessory designed to facilitate the correct and efficient insertion of pistons into Nordson Ratio-Pak two-component (2K) adhesive and sealant cartridges, specifically for 200ml-400ml barrel sizes. This tool ensures proper sealing and air evacuation, which is crucial for consistent and accurate dispensing of two-part materials.

Popular Applications & Uses

- Ensuring air-free filling of two-part adhesive and sealant cartridges.- Standardizing the piston installation process in cartridge filling operations.- Preparing cartridges for dispensing various two-component materials like epoxies, urethanes, silicones, foams, coatings, and potting compounds.- Preventing piston bounce and inconsistent dispensing by ensuring proper piston seating and air evacuation.

Industries that Commonly Use It

- General Manufacturing- Aerospace/Defense- Automotive Service/Repair- Construction/ Building Services- Medical Device/ Prosthetics- LED/Electronics- Metal Fabrication- Plastic Fabrication- Marine- Furniture- Cabinet & Woodworking- Distributers & Resellers

Special and Unique Features

- Specifically designed for Nordson Ratio-Pak 200ml-400ml barrels.- Facilitates easy and standardized piston installation, crucial for consistent dispensing.- Often includes a mechanism (like a bump or pin) to open the piston's air release diaphragm during insertion, allowing trapped air to escape.- Ensures proper sealing of the cartridge, preventing leaks and material contamination.- Helps prevent air entrapment between the piston and the fluid column, which can lead to piston bounce and inconsistent deposits.

Key Properties

- Optimized for use with Nordson Ratio-Pak cartridge systems.- Precisely sized for 200ml-400ml Ratio-Pak barrels.- Aids in achieving consistent and repeatable piston placement, enhancing dispensing accuracy.- Constructed for durability and repeated industrial use.

Surface Compatibility

- Compatible with the internal surfaces of Nordson Ratio-Pak 200ml-400ml cartridges, typically made from polypropylene (PP) or nylon.- Designed to work effectively with various piston materials, such as MDPE used for piston rear seals.

Known backups / known substitutes

- Manual piston insertion, which is less consistent and carries a higher risk of air entrapment and improper sealing.- Piston insertion tools from other manufacturers designed for similar two-component cartridge systems (e.g., MixPac).- Automated piston insertion equipment, typically used for high-volume production lines.

Comparison Note

This Piston Insertion Tool significantly improves upon manual piston insertion by providing a standardized, repeatable, and air-free method for preparing two-component cartridges. It reduces material waste and rework caused by improperly seated pistons or trapped air, leading to more reliable and precise dispensing. Compared to fully automated systems, it offers a cost-effective and efficient solution for medium-volume cartridge filling and preparation operations.
