Comprehensive Applications
From Masterbatch to Mega-Compounds: Solutions for Every Sector.
We don’t just sell machines; we provide process-specific configurations optimized for your material’s unique behavior.
- Masterbatch & Additives
High-concentration dispersion requires aggressive mixing without degrading the polymer.
Filler Masterbatch (CaCO3 / Talc / TiO2):
- The Challenge: Handling huge volumes of powder (up to 85% loading) causes severe wear and feeding issues.
- Our Solution: SAT Series with high torque and deep-channel screws ensures high intake capacity. We use W6Mo5Cr4V2 wear-resistant barrels to extend service life by 3x.
Color Masterbatch:
- The Challenge: Even microscopic agglomerates cause streaks in films or fibers.
- Our Solution: Specialized distributive mixing elements (ZME/TME) ensure perfect pigment wetting. Our self-wiping profile guarantees fast color changes with minimal waste.
- Advanced Compounding & Modification
Enhancing polymer properties with fibers, modifiers, and alloys.
Engineering Plastics (PA, PBT, PC + GF/CF):
- The Challenge: Adding glass fiber improves strength but causes abrasion; excessive shear breaks fibers, reducing impact strength.
- Our Solution: Gentle kneading blocks and side feeders allow fiber addition downstream, preserving fiber length while ensuring homogenization.
Cable Compounds (HFFR / XLPE):
- The Challenge: Flame retardants and cross-linking agents are extremely temperature-sensitive.
- Our Solution: Tandem Systems (SAT-TDD) or TDY Counter-Rotating extruders. We separate the high-speed mixing step from the low-speed pressure buildup step, keeping melt temperatures precisely controlled.
- Petrochemical & Polyolefin Finishing
Critical equipment for polymerization plants (LDPE, HDPE, PP).
- The Mission: Turning reactor powder/melt into uniform pellets
- Our Capability: Mega-Scale Extruders (up to 360mm) capable of 60 tons/hour. These lines feature explosion-proof designs, integrated gear pumps, and massive underwater pelletizers, fully compatible with plant DCS.
- Direct Extrusion (Bypass Pelletizing)
The most energy-efficient way to produce semi-finished goods.
PET / PLA / PP Sheet & Board:
- The Innovation: Instead of pelletizing > cooling > re-heating > extruding, we combine everything.
- The Benefit: Our Planetary Roller or Twin Screw extruder equipped with a melt pump and sheet die processes undried flakes directly. This cuts energy bills by 40% and prevents IV (Intrinsic Viscosity) drop.
- Recycling & Sustainable Materials
Turning waste into high-value raw material.
PET / Film Recycling:
- The Feature: High-Vacuum Degassing.
- The Result: Multi-stage vacuum ports efficiently strip moisture and volatiles from washed flakes, allowing for direct compounding without pre-drying.
Bio-Plastics (PLA / PBAT / Starch):
- The Feature: Extended L/D Ratios (52:1).
- The Result: Provides the necessary residence time for reactive compounding and esterification processes.

FAQ
A: We are a direct manufacturer. Since 2008, we have been designing and building extruders in our own facility. We handle the core manufacturing steps—from gearbox assembly to final testing—ourselves, ensuring we have full control over quality and timelines.
A: Our factory is located in Jurong, Jiangsu, China. It houses our machining center, assembly lines, and an R&D trial center. You are welcome to visit us to inspect the production quality or run a test on our lab machines.
A: It depends on your performance requirements. The SAT Series is our proven workhorse for 90% of heavy-duty tasks. The U+ Series (15 Nm/cm³) is our flagship for maximum throughput and European-class performance.
A: Absolutely, if you prioritize Cost-Effectiveness. The EC Series is designed for applications like Color Masterbatch, Powder Coatings, and general compounding where extreme torque is not necessary. It delivers USEON's signature reliability with a standard specific torque, offering the best Price-Performance Ratio and a faster Return on Investment (ROI).
A: Choose TDY for heat-sensitive materials like PVC, XLPE, or HFFR. Its low-shear action prevents degradation. For most other mixing tasks, Co-Rotating (U+/SAT/EC) is more efficient.
A: Yes. We build Jumbo-Compounders (e.g., SAT360) with outputs over 60 tons/hour for Polyolefin finishing, featuring 24/7 continuous operation and DCS integration.
A: It allows you to produce finished sheets/boards directly from raw materials, skipping the pelletizing step. This saves up to 40% in energy and protects material quality.
A: Yes. While we are well-known for PET recycling, our twin screw technology is equally effective for a wide range of other materials:
- Film & Woven Scraps: Light-density PP/PE/PA films or fibers fed via specialized side feeders.
- Engineering Plastic Regrinds: Re-compounding ABS, PS, PC, or PA scraps from injection molding.
- Upcycling: Adding fillers or modifiers to recycled materials to upgrade their properties (e.g., PP + Talc).
Our high-vacuum degassing and melt filtration systems ensure excellent quality even with printed or moisture-laden scraps.
