Compounding & Extrusion
Compounding and extrusion are key processes in the plastic manufacturing industry. Fillers and reinforcing materials can be incorporated into a polymer matrix in various ways, creating new material properties, and ultimately transforming into specific granules. These granules, with distinct characteristics, can be used for multiple applications. The primary type of extruder used for compounding is the co rotating intermeshing twin screw extruder.
Chuangbo provides plastic compounding extruders for a series of plastic compounds, offering innovative solutions for today’s most demanding compounding applications.

Compounding and Extrusion
In the plastics manufacturing industry, compounding and extrusion are essential processes that precisely disperse additives, fillers, and reinforcing materials into a polymer matrix. Through these processes, new rheological, mechanical, thermal, and processing properties can be imparted to the material, ultimately forming high-quality plastic pellets for a wide range of applications.
The most widely used equipment for compounding is the co-rotating intermeshing twin-screw extruder, known for its excellent mixing, dispersing, and conveying capabilities. It is the industry-standard machine for engineering plastics, color masterbatch, filler masterbatch, biodegradable materials, cable compounds, and TPE/TPU modification.
CHUANGBO provides high-performance compounding and extrusion solutions for various polymer materials
We supply advanced compounding and pelletizing extruders designed for engineering plastics, elastomers, biodegradable materials, cable compounds, and masterbatch production, helping customers handle even the most demanding compounding applications.
Compounding is a melt-mixing process in which polymers are blended with additives, fillers, or reinforcing agents to achieve targeted performance. Common additives include:
- Lubricants
- Antioxidants
- Heat stabilizers
- Flame retardants
- Reinforcing fillers (glass fiber, carbon fiber, talc, calcium carbonate)
- Colorants (pigments and dyes)
- Compatibilizers and impact modifiers
The end product is known as compounds or masterbatches depending on the formulation.
