25. March 2015

Among the large contingent of Chinese machinery suppliers at the show this week, Tech-Long USA, Commerce, Calif., is showing off a new generation of rotary stretch-blow molders in booth S32001. The G5 model on display offers outputs up to 2400 bottles/hr per cavity with six to 32 cavities. It reportedly reduces energy use by 10-15% compared with previous machines and enhances compressed-air recovery by 40-55%. Improvements in speed result from use of servo motors instead of pneumatic stretch rods; an integrated gripper system for faster bottle discharge from the molds; and a new PLC with 15-in. touchscreen. Improved seals are said to reduce air-exhaust noise from 92 to 83 db. Keth Boss, CEO of Tech-Long Americas, says this is the fifth-generation machine from Guangzhou Tech-Long Packaging Machinery Co.
