KAKUUNDO (THAILAND) CO., LTD. presents "ecomaru" purging pellets, an innovative solution for injection molding machine cleaning. This product features newly developed ultra-fine, flexible GlassWool short fibers, providing an overwhelmingly large specific surface area. These soft and fine fibers effectively remove dirt and contaminants from every corner of the molding machine without causing damage, addressing common issues such as black spots, residue during color changes, and carbonization of flame-retardant resins. ecomaru is offered in two grades: GWP and GWS. GWP (PP+GW, 180-280°C) is suitable for PP, PE, GPPS, and PMMA, excelling in high-cleaning performance and resin replacement, particularly for transparent applications and color changes. GWS (AS+GW, 200-320°C) is designed for a broader range of resins including ABS, AS, HIPS, PA6/66, POM, PBT, PC, and PC-ABS, specializing in black spot removal. Key benefits include significant reduction in defect rates, cost savings by minimizing downtime and material waste, and replacing time-consuming manual disassembly cleaning. Customer case studies show a reduction in defect rates from 9.96% to 2.80% and up to a 64% decrease in purging material usage. The GlassWool also reduces screw wear and suppresses odors and fumes, improving the working environment. Additionally, ecomaru incorporates over 60% recycled special GlassWool, contributing to sustainability. Proper usage involves a combination of auto and short purging, with specific guidelines for resin replacement to ensure complete GlassWool discharge, especially for transparent materials.
