JED laboratory extruders are designed specifically for laboratory environments, primarily used for polymer material research, formulation testing, sample preparation, and small-batch pelletizing. Their core advantages lie in their compact size, high precision, and ease of operation, making them ideal for R&D applications in universities, enterprises, and research institutes. The following is a summary of key information:

I. Extruder Types and Features
Single-screw extruders: Compact and easy to operate, they are suitable for extrusion experiments with general-purpose plastics (such as PE or PP). They offer uniform feeding, precise temperature control, and stable discharge, making them easy for beginners to quickly learn and maintain. They are also easy to clean and ideal for high-frequency laboratory experiments.
Twin-screw extruders: Commonly used for complex compounding requirements, such as polymer modification and pelletizing. Their smaller screw diameter reduces material consumption and supports water cooling, ensuring uniform, smooth pellets.

II. Core Applications
Polymer plastics research (such as formulation development and performance testing).
Small-batch sample preparation and pelletizing (such as the molding of modified pellets or transparent formulations). Material compounding experiments (twin-screw versions are suitable for challenging tasks, such as TPU or PEEK modification).

Third, choose JED products to ensure equipment stability and after-sales service:
Single-screw extruder:
Small laboratory single-screw extruder: Directly shipped from Zhejiang, China, with high cost-effectiveness, suitable for testing materials such as PE/PP.

Fourth, Selection Recommendations

When purchasing, pay attention to key components: screw speed (affects production capacity and plasticizing effect; modern equipment can reach speeds of over 100-120 rpm), water jacket temperature control (to avoid premature softening or excessive resistance), and reducer design (to ensure high torque capacity). Prioritize models with a screw diameter that matches the experimental specifications.
