TPU TPR thermoplastic elastomer Plastic granules making machine lab plastic pellet machine

Thermoplastic elastomer (TPE), also known as thermoplastic rubbers (TPR), combines thermoplastic and elastomeric properties in the form of copolymers or physical blends of polymers. TPE is relatively easy to use in manufacturing, e.g., by injection molding, compared to thermoset elastomers. It is ideal for reinforcing and toughening plastic materials.

TENGDA is committed to delivering top-quality plastic granule-making machines for various TPE pelletizing applications(TPS/TPO/TPV/TPU/TPC/TPA). Our TPE extruders feature screw elements made from W6Mo5Cr4V2 (high-speed tool steel) for optimal wear resistance; The base material of barrel is 45# steel. All electrical components such as the main motor, inverter, PLC, main electrical controller, and current display are sourced from globally recognized brands such as "FUJI", "SIEMENS", "Schneider""OMRON" etc. 

1. Higher L/D ratio provides better mixing, homogenization, and devolatilization, which are essential for producing high-quality TPE granules;

2. Tightly intermeshed screws elements ensures less clearance, resulting in uniform and bubble-free granules;

3. Main feeder and conical side feeder allow for precise control of material input and the addition of additives or fillers;

4. Non-stop screen changer enables continuous operation without the need to stop the machine when changing the mesh, preventing strand breakage;

5. Advanced temperature control system ensures optimal processing conditions throughout the barrel;

6. Vacuum venting ports for efficient removal of volatiles and moisture during extrusion;

7. Hardened barrel liners and screws for increased wear resistance and longer service life.

1. Energy-saving:

  
All main motors of machine use Variable Frequency Motor(AC), eliminating three-phase asynchronous motors;

   - Easy and energy-saving speed regulation.
   - The AC motor features a simple structure, compact size, low inertia, cost-effectiveness, ease of maintenance, and durability.

   - Capable of expanding output and achieving high-speed, high-voltage operations.

   - Enables soft start and fast braking.
   - Spark-free, explosion-proof, and strong environmental adaptability.

2. High Output:

   - Our machines have been tested to achieve 10%-20% higher actual production output compared to similar models on the market.

3. Easy Installation:

   - Only need to connect to inlet and outlet water, saving up to 2 days of installation time.

4. Advanced Design:

   - Electrical components are from top brands such as "SIEMENS" and "SCHNEIDER".

   - Industry-first advanced dust cover design for a sleek appearance and easy maintenance.

   - Thicker and more heat-resistant heater to ensure the heating effect of the barrel and the service life of the heater;

   - Stainless steel pipes and valves in the barrel's water cooling system for durability.

5. Excellent Service:

   - 1-year comprehensive warranty, with an extended 3-year warranty for the main gearbox.

   - Custom layout and piping design for seamless integration into existing facilities.

   - Technical support for new product development initiatives.
