Blow Molding Machine

PET blow molding machine

During the production of PET containers, are reliability & energy consumption the key purchasing factors? The answer is yes. Only the most stable process window and lowest energy consumption can achieve the most efficient productivity.The continuous innovation of TECH-LONG's blower will directly provides a direct benefit to both uptime and cost efficiency.

TECH-LONG PET stretch blow molding machine is the first national brand of high-speed rotary stretch blow molding machine. This has been a key project of the Torch Program, a program to develop new and high technology and fill in the domestic gap in the high-speed blow molding machines field. In 2002, TECH-LONG developed and manufactured its first high-speed blow molding machine - RJM8. Our new CPX G5 blow molding machine series has realized a giant leap from 800BPH [Bottles Per Cavity per Hour] to 2,400BPH. As a leading Blow Molding Machine Supplier, we offer innovative solutions for various industries.

TECH-LONG's fifth generation of blow molding machines was developed with the most advanced stretch blow molding technology in the world pressure air is used to blow and stretch the PET preforms into containers. The CPX series has many advantages, including a high level of automation and intelligence, superior and consistent product quality high production efficiency, and low energy consumption, making it the perfect machine for PET containers' production for various types of liquid products.
