How Does An Extruder Turn PLA Into Drinking Straws?
PLA straw production lines typically involve a series of processes, including straw extrusion, cooling, and cutting.
Here’s a general overview of how a PLA straws production line works:
The straws are cut using a Haul-off and Cutter machine, and the length of the produced straws is regulated by adjusting the traction speed and cutting speed of the machine.
Following the cutting process, the diameter, length, wall thickness, or weight of the cut straws are measured manually. If they meet the production requirements, they are deemed to be essentially qualified.
At this stage, the production of straight straws is completed.
If there is a requirement to produce bent straws using PLA material, an additional step of straw forming is introduced after Step 3. Cutting. The process of forming flexible straws involves the use of a specialized straw-forming machine. Different shapes of straws necessitate the use of corresponding machines designed specifically for those shapes. For instance, a Z-shaped straw-forming machine is employed for Z-shaped straws, an expandable straw-forming machine is utilized for expandable straws, and a U-shaped straw-forming machine is employed for U-shaped straws.
Straight straws, commonly used for milk tea (PLA straws), can be directly packaged after production using a straw-aligning machine and an incline conveyor to transport them to the straw packaging machine.
Milk tea straws are typically packaged individually, so a machine designed for individual straw packaging, such as the ML31D, is used.
After individual straw packaging, if there is a need to group multiple straws together. multiple straw packing machines like ML39E will be used.
The 3 Key Factors That Determine the Performance of PLA Straw Extruder
1. Good plasticizing effect.
Ensure that the straw material after the distribution of uniform temperature heating, reach the flow state, and has good plasticity.
a. A good plasticizing effect of the straw extruder screw indicates that it can effectively melt the straw material into various specifications of straws and produce multiple sizes of straws. It can also be used to produce products like pen cores and pen barrels.
b. A good plasticizing effect of the straw extruder improves product quality. The produced straws are more uniform, with more precise dimensions. The surface of the produced straw products is smooth, without defects such as bubbles or burrs. The quality is more stable, meeting the high-quality requirements of customers for straw products.
2. Large amount of extrusion
It enables large daily output of straws and ensures good quality straws.
3. Precise temperature control
In the case of low precision, the temperature is difficult to control and requires multiple debugging, which is likely to waste a lot of straw material.
