Micro Conical Extruder Introduce

Overview

The RT-739 Micro and Lab Compounders offer exceptional value, delivering superior performance and long-lasting durability. Thanks to their robust design—including a durable motor drive, housing, barrel, and screws—these compounders ensure longer lifespans (over 10 years) and reliable, reproducible results over time. With the advanced DGRIGHT technology, you can easily adjust compound volumes (15, 10, or 5 ml), making it incredibly versatile.

These compounders are built for better mixing, allowing for easy control of residence time and offering higher output, thanks to the fully intermeshing screw design. Whether you’re working with injection molding, film production, or (multi) filament extrusion, the RT-739 delivers faster and more consistent in-line shaping compared to any other lab extruder on the market.
Additional features include continuous screw torque monitoring, effortless cleaning (with water cooling and cleaning compound), and no need for specialized screw design knowledge. The RT-739 can also be easily scaled up to larger parallel twin-screw extruders—a capability that sets it apart from the competition. If you only need to melt and extrude materials (such as filaments or films), the RT-739 can operate in continuous mode. It also supports vertical extrusion and can dose fluids without leakage.

In short, the RT-739 Micro and Lab Compounders are perfect for small to medium sample sizes, providing great results that are reproducible, reliable, and fast, with easy scalability for future growth. Ideal for formulation development, feasibility studies, material screening, and resolving technical marketing challenges.

Product Features

Micro-Design: The micro-compounder is designed to handle small batch volumes, with a capacity of up to 15ml. This makes it ideal for research and experimental setups that require precise control over limited sample sizes.

Advanced Configuration: Featuring spiral and pitch-variable screws, the system efficiently prevents high-viscosity polymers from climbing up the screws. Additionally, the recirculation channel is engineered to simulate accurate residence times, ensuring optimal processing conditions.

Versatile Processing: Equipped with advanced rheological control software, the machine allows for the precise measurement of the mixture’s flow properties. Multiple experimental modes are supported, including single-cycle compounding, timed-cycle compounding, continuous feed compounding, constant-speed compounding, and constant-torque compounding, offering flexibility for various testing scenarios.

Ease of Cleaning: The barrel design allows for a full 180° opening, providing easy access for thorough cleaning and maintenance of both the chamber and screws, helping to maintain process hygiene and efficiency.

User-Friendly Operation: With a streamlined process that takes only ten minutes from melting and polymerization to extrusion and injection molding, the system ensures rapid production cycles, making it a practical tool for fast-paced research environments.

Extended Functionality: A range of modular extensions are available, enabling the system to support additional applications such as extrusion, injection molding, film drawing, and spinning, enhancing its utility for diverse processing needs.

Product Specifications

Micro Melt Spinning Machine System

The micro melt spinning machine consists of RT-739 and RT-742 models. Among them, RT-739 is a front-end micro conical twin-screw extruder, mainly used for melting, co-mingling and extrusion of raw materials; RT-742 is a melt spinning machine, which consists of two parts, namely, a silk thread winding device and a silk thread secondary stretching and spinning device. The hardness of the barrel of the melt spinning machine is 64HRC (Rockwell Hardness), and the hardness of the screw is 54HRC (Rockwell Hardness), which is the highest in the industry. The melt spinner can withstand acid and alkali values of PH 0~14 (full range coverage), strong acid and alkali corrosion resistance and super hardness can be late to meet the needs of a variety of polymer research and development; for example, strong acid and alkaline materials, ultra-high viscosity engineering materials, and even can be used for the need to add ceramics or metal powders modified polymer materials. The unique rheological software can be used to monitor the screw torque, shear viscosity, shear rate and shear stress in real time, which can be used to assist in the scaling up of production equipment.
