lab dispersion kneader machine for plasticating and mixing rubber and plastic testing for TPR TPE masterbatch polymer rubber etc.
Thermoplastic Rubber (TPR), also known as Thermoplastic Elastomer (TPE), it is a versatile material widely used in footwear, seals, grips, toys, and various flexible molded products.
To produce and process TPR efficiently and consistently, some machines are essential across different stages of production—from compounding to molding.
Here’s a categorized list of essential machines:
1. Compounding & Mixing Equipment
The compound mixing machines are crucial for formulating and homogenizing TPR blends. Bacially , the following equipment are essential on this mixing process :
* Dispersion Kneader – The dispersion kneader is one of the most critical machines in TPR production. It’s designed for high-shear, uniform mixing of rubber and thermoplastic components with fillers, plasticizers, and other additives. The dispersion kneader is perfect for uniform mixing of rubber, TPR, TPE,SBS, SEBS with PP or other thermoplastics in lab and production settings. Ideal for batch mixing.
* Internal Mixer (Banbury Mixer) – High-efficiency industrial mixer for mass production.
* Twin-Screw Extruder – For continuous compounding and pelletizing of TPR compounds.
* Open Mill (Two-Roll Mill) – Used for refining, blending, and pigment mixing.
2. Pelletizing & Granulation Machines
After compounding process, TPR material often need to be pelletized for further granulate extruding processing. Here are
* Strand Pelletizer – Cools and cuts extruded strands into uniform pellets.
* Underwater Pelletizer – Used for high-speed pelletizing in production lines.
3. Forming & Molding Machines
After pelletizing process , the TPR material then need to be processed into final products via:
* Injection Molding Machine – Common for making TPR footwear, seals, grips, etc.
* Extrusion Line – Produces profiles, sheets, tubing, etc.
* Blow Molding Machine – For hollow TPR items, e.g., toys, bottles.
4. Testing & Laboratory Equipment
When the TPR material is finished , in order to control material quality , it need to go to another procedure R&D, and formulation optimization.
* Lab Kneader / Lab Mixer – Small-batch mixers for testing compounds.
* Rheometer – Measures flow and deformation under stress.
* Mooney Viscometer – Analyzes viscosity of rubber materials.
* Tensile Tester – Tests strength and elongation of finished TPR.
* DSC/TGA Analyzer – Thermal analysis for material characterization.
From mixing raw materials to molding finished goods, each machine plays a vital role in the TPR production process. Whether you’re in R&D or full-scale manufacturing, having the right equipment—such as a dispersion kneader, extruder, pelletizer, and molding machines—ensures product quality, process efficiency, and long-term production success.
