PVC Compound Production Lines and Turnkey Compounding Systems
Monomex develops complete process solutions for the production of high-quality PVC compounds. In the PVC industry, product quality depends on precise raw material handling, accurate dosing, controlled mixing, efficient extrusion, effective venting, stable pelletizing and reliable packaging.
Monomex PVC compound production lines are designed as complete turnkey systems, covering every stage of the process from raw material storage and feeding to hot-cold mixing, twin screw extrusion, single screw discharge extrusion, pelletizing, cooling, conveying and packaging.
With strong process engineering know-how and advanced extrusion technology, Monomex provides reliable solutions for PVC-P, PVC-U, cable compounds, profile compounds, shoe sole materials, hoses, medical applications, films, sheets, fittings and injection molding grades.
High-Quality PVC Compounding with Process Reliability
PVC is a temperature-sensitive polymer. For this reason, screw design, residence time, melt temperature, shear control, vacuum performance and pelletizing method are critical factors in PVC compound production.
Monomex PVC compounding lines are engineered to process different formulations, high filler ratios and various additive systems. Stabilizers, plasticizers, fillers, pigments, processing aids, flame retardants and performance additives are accurately fed and homogeneously dispersed according to the required formulation.
This results in stable production, lower waste rates, consistent pellet quality and reliable end-product performance.
Soft PVC / PVC-P Applications
Monomex PVC compound production lines provide high mixing efficiency and controlled plasticizing performance for flexible PVC applications.
Typical applications include:
PVC cable insulation compounds
PVC cable sheathing and bedding compounds
Shoe and shoe sole materials
Foamed PVC-P compounds
Profile and hose extrusion compounds
Medical-grade PVC compounds
Flexible PVC injection molding compounds
Flooring, film and sheet applications
Rigid PVC / PVC-U Applications
In rigid PVC compound production, process stability, temperature control and homogeneous additive distribution are essential for final product quality.
Typical applications include:
PVC window and door profile compounds
Interior and exterior PVC profile materials
PVC pipe and panel compounds
Injection molding grades for fittings and technical parts
Blow molding grades for bottles, containers and hollow parts
PVC alloys and polymer blends
Film and sheet compounds for calender feeding
MEX T + MEX S Two-Stage PVC Compound Extrusion System
At the heart of Monomex PVC compounding plants is the two-stage extrusion system, consisting of the MEX T twin screw extruder and the MEX S single screw discharge extruder.
The MEX T twin screw extruder is designed for intensive mixing, additive dispersion, plasticizing and process control. The MEX S single screw discharge extruder ensures gentle melt transfer, stable pressure build-up, improved venting performance and consistent feeding to the pelletizing system.
This two-stage system provides key advantages in PVC compound production:
High mixing homogeneity
Controlled melt temperature
Lower shear stress on PVC material
Improved vacuum and degassing performance
Stable pellet quality
High process flexibility
Reliable continuous production
Fast adaptation to different PVC formulations
Tandem PVC Compound Extrusion System
Monomex tandem PVC compounding systems are developed for producers who require high product quality, process stability and formulation flexibility.
The tandem system separates the mixing and pressure-building functions into two extrusion stages. This allows better process control, especially for heat-sensitive PVC formulations, high filler compounds and demanding additive systems.
This design helps manufacturers achieve more consistent melt quality, better pellet uniformity and improved long-term production reliability.
Pelletizing and Cooling Systems
Pellet quality has a direct impact on downstream processing performance. Monomex integrates the most suitable pelletizing system according to the PVC formulation, production capacity and final application.
Depending on the process requirements, Monomex PVC compounding lines may include:
Dry air pelletizing systems
Hot-cut pelletizing systems
Cooling and screening systems
Pellet conveying systems
Packaging and bagging units
The main objective is to achieve low dust formation, uniform pellet size, stable bulk density and reliable flow behavior.
PVC Feeding and Dosing Systems
Selecting the correct feeding and dosing system is one of the most important factors in PVC compound production. PVC formulations often include resin, fillers, stabilizers, plasticizers, pigments and specialty additives that must be added in the correct sequence and with high accuracy.
Monomex provides gravimetric and volumetric feeding systems according to the formulation, raw material characteristics and production capacity.
Available feeding solutions include:
Single screw feeders
Twin screw feeders
Liquid dosing systems
Rotary valve feeding systems
Loss-in-weight gravimetric feeders
Central recipe management and process control systems
With the right feeding configuration, formulation deviations are reduced, raw material losses are minimized and product quality becomes more consistent.
