Since then, we have consistently improved and advanced these heads, creating models tailored for a wide range of applications. Hundreds of our mixing heads are currently operating effectively for a diverse clientele both domestically and internationally.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Specifications<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Comes with the control panel to ensure an accurate parameter settings and to initiate automatic metering with a single touch.<\/li>\n\n\n\n<li>Direct metering of each raw material from the mixing head.<\/li>\n\n\n\n<li>Minimal to No Air in the blend during injection.<\/li>\n\n\n\n<li>Outstanding mixing performance for both initial and residual flows.<\/li>\n\n\n\n<li>Equipped with a constant balance pressure nozzle (optional) to sustain discharge pressure at the desired level regardless of discharge volume fluctuations.<\/li>\n\n\n\n<li>The exceptional durability is achieved by utilizing specialized steel combined with advanced surface treatment techniques.<\/li>\n\n\n\n<li>The exceptional sealing system prevents cross-contamination between materials within the mixing head.<\/li>\n\n\n\n<li>DOP Circulation device effectively prevents the material buildup on the cleaning shaft and discharge piston.<\/li>\n\n\n\n<li>The Minimum discharge time is as fast as 0.1 seconds.<\/li>\n\n\n\n<li>A range of sizes is offered to accommodate various discharge volumes.<\/li>\n\n\n\n<li>Easy design provides a quick disassembly and a user-friendly maintenance.<\/li>\n\n\n\n<li>Compact, lightweight, and small size for easy handling.<\/li>\n\n\n\n<li>Equipped with a step-less air regulator
