The pellets are transferred to another extrusion molder. The second straw extrusion is fitted with a different type of die, which produces a hollow tube shape. The pellets are dumped in a hopper on one end of the drinking straw machine and are forced through a long channel by a screw mechanism. This screw is turned in the barrel with power supplied by a motor operating through a gear reducer. As the screw rotates, it moves the resin down the barrel. As the resin travels down the heated channel, it melts and becomes more flowable. To ensure good movement and heat transfer, the screw fits within the barrel with only few thousands of an inch clearance. It is machined from a solid steel rod, and the surfaces almost touching the barrel are hardened to resist wear. By the time the resin reaches the end of the barrel, it is completely melted and can be easily forced out through the opening in the die.

The resin exits the die in a long string in the shape of a straw. It is then moved along by a piece of equipment known as a puller which helps maintain the shape of the straw as it is moved through the rest of the manufacturing process. In some processes, it is necessary to pull the straw through special sizing plates to better control the diameter. These plates are essentially metal sheets with holes drilled in them. Eventually, this elongated tube is directed through a cooling stage—usually a water bath. Some operations run the plastic over a chilled metal rod, called a mandrel, which freezes the internal dimension of the straw to that of the rod. Ultimately, the long tubes are cut to the proper length by a knife assembly.

While sitting in his younger brother Albert's fountain parlor, the Varsity Sweet Shop in San Francisco, Friedman observed his young daughter Judith at the counter, struggling to drink out of a straight straw. He took a paper straight straw, inserted a screw and using dental floss, he wrapped the paper into the screw threads, creating corrugations. After removing the screw, the altered paper straw would bend conveniently over the edge of the glass, allowing small children to better reach their beverages. U.S. patent #2,094,268 was issued for this new invention under the title Drinking Tube, on September 28, 1937. Friedman would later file and be issued two additional U.S. patents and three foreign patents in the 1950s relating to its formation and construction. Friedman attempted to sell his straw patent to several existing straw manufacturers beginning in 1937 without success, so after completing his straw machine, he began to produce the straw himself.

The Flexible Straw Corporation was incorporated on April 24, 1939 in California. However, World War II interrupted Friedman's efforts to construct his straw making machine. During the war, he managed the optometry practice of Arthur Euler, O.D., in Capwells' Department Store in Oakland, California, and continued to sell real estate and insurance to support his growing family. Friedman obtained financial backing for his flexible straw machine from two of his brothers-in-law, Harry Zavin and David Light, as well as from Bert Klein, a family associate. With their financial assistance, and the business advice of his sister Betty, Friedman completed the first drinking straw machine in the late 1940s. Although his original concept had come from the observation of his daughter, the flexible straw was initially marketed to hospitals, with the first sale made in 1947. It is now cited as an early example of Design for All.

The three series of our drinking straw machine: drinking straw extrusion machine, flexible straw making machine, drinking straw packing machine was certified for the EU CE certification, Notice No. 1067 in August 2009.

Today, the demands of PLA straw become greater and greater with human awareness of environmental protection grows. PLA is short for biodegradable polyactic acid, belongs to the family of Polyester. Polylactic acid is lactic acid by the main raw material for polymerization of polymers, raw material sources can be fully regenerated, mainly maize, cassava as raw materials. Poly-lactic acid production process clean and biodegradable products to achieve the cycle in nature, it is an ideal green polymer material. But the PLA materials for the production of straw is very high technological requirements, our company has successfully developed a PLA drinking straw machine and PLA flexible drinking straw machine.

The largest manufacturer of PLA is Nature Works Co.,Ltd in U.S. And Hisun Biomaterial Co.,Ltd in China comes the second. Their current output is 70 thousand tons and 5 thousand tons. PLA has many applications ranging from extrusion, injection molding, and membrane to spinning and other applications in many fields.

Several years ago, in the straw business we often see such a busy scene a group of people working in the workshop. Drinking straws and plastic packing were put directly in the air. But later, the labor costs grow. And the problem of health which brought on by Hand-packed is difficult to control. More and more drinking straw manufacturers need automatic packing machine to pack instead of manually urgently          We regard the needs of our customers’ as our responsibility. In 2003, through the efforts of our company's technical team, China's first Multi-drinking straws packing machine was born. The development of Multi-drinking straws packing machine completely changes the actuality that slow rapid, unsanitary environment and expensive human labor of hand-packing. A Multi-drinking straws packing machine can replace of 15 person's hand-packing.
