In the production process, many manufacturers will encounter such problems: due to the pressure of the machine head, the unreasonable size of the mold and other reasons, whether it is a thick wall or a thin wall of the straw, the production is often not round enough, which requires the use of vacuum to round these unqualified straws. However, this process is often time-consuming.
In order to solve this problem, Mr. Ling Hongjun, an expert in straw machinery from the think tank of the Chinese Academy of Management Sciences, has developed a unique patented screw structure BM separation type + pineapple nail structure, which can be produced very round without vacuuming.
The PLA material can be fully plasticized and mixed during the extrusion process, so that the straw is very round after production.
In addition to straws with a thick wall of more than 30 wires, such as cotton swab sticks, lollipop sticks, etc., which still need vacuum suction to ensure roundness during the production process, straws of other specifications can be easily produced without vacuum assistance
Straw machineThat's all for the patented screw construction, which produces all the contents of a very round straw without vacuuming.
