Equipment advantages

How to develop PLA polylactic acid/starch based extrusion sheet equipment? Through multiple discussions, it is believed that technological innovation, structural optimization, precision manufacturing can be carried out from five aspects to achieve high output and low energy consumption of the equipment, and to create a domestic PLA polylactic acid/starch based twin-screw extrusion sheet equipment.

1) Twin screw combination technology

Years of accumulated experience in the development and design of twin-screw configurations are combined with software technology for optimization. Special double headed threaded components and screw combinations are used to achieve various functions such as conveying plasticization, mixing and blending, shear dispersion, homogenization, exhaust volatilization, and pressure building extrusion. Especially in the removal of crystallization water inside PLA materials, it has extremely high efficiency. The specially designed exhaust port does not emit material, allowing for free and smooth flow, achieving low-temperature extrusion, and avoiding thermal degradation of PLA;

2) Vacuum exhaust technology

Multi stage forced exhaust ensures that PLA materials do not undergo hydrolysis or crystal point formation during melting and plasticization processes. The special three-stage vacuum exhaust technology and oil gas separation technology, with ultra large pumping volume and ultra-high vacuum degree, greatly reduce the viscosity reduction of PLA.

3) High strength roller internal spiral flow channel technology

The internal spiral flow channel structure design of the high-strength roller is matched with a water temperature control system, which enables the roller to have accurate temperature control and heat transfer effect;

4) Intelligent remote control technology

Through our company's server IDC center industrial data center and industrial data collection and analysis software, remote monitoring network equipment, standard motor health detection and analysis system, equipment energy management optimization system, etc., we can achieve remote monitoring of equipment in customer factories and collect and store various process data, conduct process data analysis, and optimize production process formulas.

5) Craftsmanship spirit in equipment manufacturing process

The selection of components, manufacturing processes, processing accuracy, heat treatment and surface treatment, appearance design and other industrial designs are carefully considered to ensure the stability and reliability of the equipment and improve its performance.

Product Application

Widely used in fields such as electronic product casings, automotive components, medical devices, clothing fibers, agricultural films, food packaging, tableware, etc.
