What is the Most Important Factor When Choosing a Straw Machine?

 There are many types of straw machines on the market, but the most critical point in choosing a straw machine is the screw of the straw machine. The design of the screw determines the production quality of the straw. A suitable screw is essential for producing high-quality PLA (polylactic acid) straws.



When selecting a straw making machine, it’s important to consider the length-to-diameter ratio of the screw. This ratio is particularly crucial for producing PLA straws. The larger the ratio, the better the mixing effect of the screw, which enhances the uniform plasticization of the raw materials and ensures the consistent quality of the PLA straws. 

For example, straw machinery expert Mr. Ling Hongjun developed a PLA straw extruder that features a patented screw design incorporating a pineapple pin and BM separation structure. With a length-to-diameter ratio of 33:1, this screw design supports both PLA and PP (polypropylene) materials. This advanced design improves the mixing and plasticization of the raw material, ensuring the production of high-quality PLA straws.

In addition to the screw’s length-to-diameter ratio, the heating system on the screw is another critical consideration. A highly efficient infrared heating coil, combined with a cooling fan, can ensure stable heating temperatures while conserving energy. This setup prevents the production environment from being affected by temperature fluctuations, further contributing to consistent straw quality.

Beyond the screw design, you should also consider the type, color, and shape of the straws you intend to produce.

·         Type: Different machines cater to different straw types, such as milk tea straws, drinking straws, and artistic straws. For instance, if you’re looking to produce milk tea straws, you can choose the ML12 PLA two-color milk tea straw machine, which can realize the production of two-color milk tea straws and has a large extrusion volume. It is a professional straw machine for producing PLA straws.

 

PLA Two Colour Drinking Straw Machine

·         Color: There are single-color straw machines, two-color straw machines, five-color straw machines, etc. If you want to produce colorful straws, you can choose the ML15 five-color straw machine, which can realize the production of straws in multiple colors and is a professional straw machine for producing various beverage straws.

Five Colors Drinking Straw Machine

Shape: If you’re planning to produce bendable straws, the ML24 high-speed series fully automatic bending straw machine could be an excellent option. This machine automatically processes straight straws into bendable ones and efficiently delivers finished products, making it highly effective for large-scale production.

PP Flexible Straw Auto Making Machine

In summary, choosing a straw making machine or Straw Making Machines Manufacturer with the right screw design ensures both the consistent quality and production efficiency of PLA straws. Additionally, consider your specific needs, such as the type, color, and shape of the straws you want to produce. If you’re still unsure about which straw machine to choose, feel free to consult experienced straw machine experts in China.
