TSH-P Twin Screw Extruder PLA + Starch Resin Granules Making Extrusion Machine

TENGDA twin screw resin extruder features two intermeshing screws that rotate within a heated barrel, providing superior mixing, melting, and homogenization capabilities compared to single screw extruders. With a L/D ratio of 48:1, it’s excels in producing a wide range of biodegradable granules, such as PLA/PBAT/PBS + starch Resin Granules. They are ideal for applications requiring intensive mixing, such as compounding, reactive extrusion, and processing of heat-sensitive materials. The unique design of this resin extruders allows for better control over residence time, temperature, and shear, resulting in stable product quality and improved efficiency. 

1. Plug and play design: all systems of the extruder are installed at the base of the principal machine and can be activated integrally once power and water supplies are properly set up;

2. Touchscreen process control system regulates and monitors the mixing process in real time;

3. L/D ratio: 48:1, focus on biodegradable granules production line;

4. The barrels, screw elements, and gearbox of the main extruder are all manufactured using CNC milling machining centers;

5. The cooling system requires only connection to inlet and outlet water, reducing installation costs for customers;

6. Free of debugging, fast installation;

7. Capacity is increased by 10%-20%;

8. Energy-saving is increased by 5%-15%;

9. Suitable to operate for small-scale runs in the lab to large-scale manufacturing.

This Twin Screw Extruder is well-suited for producing a wide range of biodegradable granules：

1.  PLA/PBAT/PBS etc. Biodegradable resin+Biomass filler(starch、plant fiber+lignin etc.)+other additives;
2. PLA/PBAT/PBS etc. Biodegradable resin+minerals filler(CaCo3、Talcum power etc.)+other additives;
3. PLA/PBAT/PBS etc. Biodegradable resin+Biomass filler(starch、plant fiber+lignin etc.)+other additives+minerals filler(CaCo3、Talcum power etc.)+other additives.

These biodegradable materials are typically used to produce: disposable tableware, non-woven fabrics, packaging materials, agricultural coatings, toys, coatings, glues, fibers and other biodegradable products.

What is a twin screw extruder used for?

A twin screw extruder is used for mixing, compounding, and granulating various polymer materials. It is particularly effective for processing materials that require thorough mixing and homogenization, such as resin granules.

How does a twin screw extruder work?

A twin screw extruder operates by feeding polymer materials into a heated barrel where two intermeshing screws rotate. These screws mix, melt, and homogenize the materials, which are then forced through a die to form the desired shape or granules.

What are the benefits of using a twin screw extruder for resin granules making?

The intermeshing screws provide excellent mixing capabilities, ensuring uniform dispersion of additives and fillers. Additionally, the efficient mixing leads to fewer rejected products.

How do you maintain a twin screw extruder?

Regular Cleaning: Use effective cleaning materials to prevent residue buildup.

Component Inspection: Check and replace worn screws and barrels.

Proper Storage: Clean the extruder, loosen screws, and protect the power cord.
