Researchers working on new materials have all experienced this: They painstakingly produce a sample in the lab using a desktop spinning extruder, and the performance seems promising. However, when they confidently prepare to scale up the production line, the resulting product either lacks strength, has a rough surface, or simply cannot be extruded. Upon investigation, the reason turns out to be that the shear strength of the small-scale equipment was too weak, or the residence time varied too much.

This creates an awkward situation: small-scale test data looks good, but lacks value for scale-up. To obtain reliable pilot-scale data, you have to borrow production line equipment, requiring hundreds of kilograms of material per startup, resulting in high costs, long cycles, and frequent queues.

The HARTEK desktop spinning extruder machine is designed precisely to solve the problem of “scaling-up distortion.” It’s not just a simple desktop extruder, but a scaled-down industrial spinning production line.

Why can data from a desktop spinning extruder machine be directly used for mass production?

The key lies in two points: First, the shear rate and distributive mixing capacity of the conical twin-screw extruder are specifically designed to closely resemble the flow field of a large conical twin-screw extruder. Second, its die, metering pump, spinneret, and draft rollers are all scaled down to industrial-grade standards, not toy-level simplifications. This means that the optimal temperature, screw speed, and draft ratio found on this equipment can be directly used as initial settings for large-scale production lines.
