Product Name
MixPac Plungers for DMA50 & DMA51 Dispensers (PLA & PLB series, All ratios - 1:1, 2:1, 4:1, 10:1)
Brief Description
MixPac Plungers are essential replacement components designed for use with DMA50 and DMA51 manual dispensing guns. These plungers facilitate the accurate and consistent dispensing of two-component (2K) adhesives, sealants, and other reactive materials from 50ml (and sometimes 75ml) "square-back" cartridges. They are crucial for ensuring the correct mixing ratios (1:1, 2:1, 4:1, 10:1) of the two separate components, which is vital for the adhesive's performance and bond strength.
Popular Applications & Uses
- Dispensing two-part epoxy, polyurethane, silicone, and methacrylate adhesives.- Applying sealants in construction and building services.- Bonding components in the electronics industry and potting electronic components.- Repair and assembly tasks requiring precise application of two-component materials.- Woodworking and cabinetry projects requiring strong adhesive bonds.- Mold making and casting applications using silicones and urethanes.- General industrial assembly lines and portable applications for adhesives and sealants.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Cabinet & Woodworking- Chemical Industry- Construction/ Building Services- Concrete- Distributers & Resellers- Energy- Fabrication- General Manufacturing- LED/Electronics- Medical Device/ Prosthetics- Metal Fabrication- Mold Making/ Casting- Plastic Fabrication
Special and Unique Features
- **Ratio Specificity:** Available for all common mixing ratios (1:1, 2:1, 4:1, 10:1) to match various two-component adhesive formulations.- **Universal Compatibility:** Designed to work with standard 50ml “square-back” cartridges (A-system and B-system designs) from various brands.- **Easy Interchangeability:** Plungers can be easily swapped out to change the dispensing ratio of the DMA50/DMA51 dispenser, offering versatility.- **Precision Dispensing:** Ensures accurate metering of components, critical for optimal adhesive performance and minimizing waste.- **Durable Construction:** Crafted from high-quality plastic materials to withstand repeated use in demanding environments.- **System Integration:** Part of the comprehensive MixPac system, designed to work seamlessly with MixPac dispensers and cartridges for reliable results.
Key Properties
- **Material:** Typically made from durable plastic (e.g., PBT & Reinforced Nylon for the DMA gun itself, plungers are plastic).- **Compatibility:** Specifically designed for MixPac DMA50 and DMA51 manual dispensers.- **Ratio Options:** Available for 1:1, 2:1, 4:1, and 10:1 mix ratios.- **Cartridge Type:** Compatible with 50ml (and some 75ml) dual-barrel, square-back cartridges.- **Function:** Pushes pistons through cartridges to dispense two-component adhesives.
Surface Compatibility
MixPac plungers themselves do not directly contact the bonding surfaces. Their compatibility is indirect, enabling the precise application of various two-component adhesives and sealants. Therefore, surface compatibility depends entirely on the specific adhesive or sealant being dispensed, which can include materials like: - Metals- Plastics- Wood- Composites- Concrete- Ceramics- Glass
Known backups / known substitutes
- **Other MixPac Plunger Series:** While PLA and PLB are mentioned, other MixPac plunger series might exist for different dispenser models or cartridge types.- **Conversion Kits:** MixPac offers conversion kits for some DM-series and DP-series dispensers to change ratios, which might include plungers.- **Generic Hand Plungers:** For very low-volume or non-critical applications, generic small manual hand plungers might be used, though they may lack the precision and reliability of MixPac plungers.- **Alternative Dispenser Systems:** Entirely different two-component dispensing systems (manual, pneumatic, or battery-powered) from other manufacturers (e.g., Cox, MK) or other MixPac lines (e.g., DM2X, DP2X) would use their own specific plungers or drive mechanisms.
Comparison Note
MixPac plungers for DMA50/DMA51 dispensers are distinguished by their integration into a highly reliable and precise dispensing system. Unlike generic plungers, they are engineered to ensure a perfect fit and consistent force application within MixPac's square-back cartridges, guaranteeing accurate mixing ratios for two-component adhesives. This system approach, where plungers, cartridges, and dispensers are designed to work seamlessly together, minimizes waste, prevents cross-contamination, and delivers reproducible bonding results, which is crucial for professional and industrial applications.
