Melt Pump for 1.2m Two-Color Sheet Extrusion Line
In the competitive plastic processing industry, 1.2m two-color sheet extrusion lines are widely used for food packaging, automotive interiors, and electronic components—demanding strict color separation, uniform thickness, and consistent quality. However, traditional extrusion systems often struggle with pressure fluctuations, uneven material blending, and high energy consumption, leading to costly scrap and limited productivity. Our specialized melt pump addresses these pain points, becoming the core upgrade for high-end 1.2m two-color sheet production lines.
Designed as a positive displacement conveying device between the extruder and die, our melt pump forms the advanced "extruder + melt pump + die" configuration ¹, separating metering, pressure boosting, and stabilization from the screw system. For two-color sheet extrusion, this separation is critical: it eliminates the "pulse effect" caused by screw rotation ⁵, controlling pressure fluctuation within ±0.5% and flow precision to 0.5-1%. This ensures the two polymer melts (PP, PE, PET, PS, or PC) maintain exact proportions, achieving sharp color boundaries and consistent thickness tolerance across the 1.2m width—meeting the strict standards of premium packaging and automotive industries.
Our melt pump delivers tangible benefits for 1.2m two-color sheet lines. Productivity increases by 15-30% ² as the pump takes over pressure-building, allowing the extruder to operate at optimal speed while reducing screw load. Energy consumption drops by 10-30% ⁸, cutting electricity costs significantly. The stable melt flow minimizes material degradation and scrap rates, especially valuable for two-color production where color mismatch waste is costly. Additionally, the pump’s high-temperature resistance (up to 350℃) ³ and wear-resistant alloy components ⁵ handle high-viscosity materials and filled polymers, extending equipment lifespan by reducing extruder wear.
Versatility is a key advantage. Our melt pump seamlessly adapts to 1.2m two-color lines processing thermoplastics like PP, PE, PET, ABS, and biodegradable materials (PLA, PBAT) ³. Whether producing food-grade PET sheets or impact-resistant PP automotive panels, it maintains precise flow control for each color stream, preventing layer separation and ensuring uniform texture. The linear relationship between pump speed and flow ⁶ simplifies process adjustment—operators can fine-tune output without frequent 螺杆 parameter changes, reducing downtime and training costs.
Backed by industry-proven technology, our melt pump is engineered for reliability in continuous 1.2m two-color sheet production. It features optimized gear profiles for smooth melt transfer, advanced sealing systems to prevent leakage, and precise temperature control to protect material properties ⁷. As plastic processing moves toward precision and sustainability, our melt pump is the strategic investment to elevate your 1.2m two-color sheet line—delivering higher quality, lower costs, and stronger market competitiveness.
