X2F’s Controlled Viscosity Molding (CVM) Technology

Conventional injection molding relies on extreme heat and pressure to force material into a mold —conditions that can degrade polymer chains and cause defects like warpage and sink marks.

X2F’s CVM Systems offer a breakthrough alternative. Our patented low-pressure molding process continuously melts and pumps material into the mold while precisely controlling parameters like screw back pressure, cavity pressure, and torque. The result is optimized material flow, superior process stability, and consistently high-quality molded parts.

  • X2F’s Patented Process: Eliminates the need for traditional injection molding’s screw, barrel, and heat-based shearing.
  • Patented Extruder Screw: Enables on-demand polymer manipulation for precise control.
  • Enhanced Flexibility: Adapts dynamically within the process, improving efficiency and customization.
  • Preserves Material Integrity: Avoids damaging the molecular structure of polymers and prevents breakdown of glass fibers or additives.
  • Dynamic Adaptability: Operates in real-time, unbound by conventional pre-measured “shot-to-shot” injection molding.
  • X2F’s Process Is: Ideally suited for automated molding and seamless integration with automation.

  • Lower Pressure and Clamp Tonnage
    The CVM process uses up to 70% less pressure than conventional methods, significantly reducing the required clamp tonnage and enabling lighter, less costly molds.
  • Pressure-Controlled Molding
    CVM is pressure-controlled, preserving the polymer’s natural characteristics and avoiding excessive pressure and shear that can degrade material properties.
  • Adjustable Gate-Freeze Time
    CVM allows for flexible gate-freeze timing, which enhances control over filling speed and time. This reduces defects such as warpage, stress, and filler orientation issues.
  • Material Versatility
    CVM can handle a wide variety of materials, from low- to high-viscosity substances, offering greater versatility compared to conventional injection molding.
E60Vi Technology Highlights
  • Pulse Packing
    The patented “Pulse Packing” method ensures smoother, more effective part packing, reducing internal polymer stress and improving part quality.
  • Faster Cycle Times
    By minimizing shear-induced heat, CVM achieves cycle times that are equal to or shorter than traditional injection molding.
  • Energy Efficiency
    CVM uses less energy to melt and move materials, lowering overall energy consumption by up to 80% — while also reducing the machine footprint by 50%.
  • Polymer and Filler Integrity
    CVM maintains polymer and filler integrity by avoiding the extreme pressures and shear forces of traditional methods.
