Zhenxiong two-step molding PET bottle solution

The injection molding machine manufacturer Zhenxiong Group Co., Ltd. exhibited its CHEN-PET two-step molding PET bottle solution at the show. In 1998, this system debuted at the K show in Cologne, Germany. More than forty sets of CHEN-PET are in use worldwide.

PET bottles are manufactured in two ways, one-step and two-step. One step is to inject PET into the tube blank and blow it into a given bottle shape while it is still not cooled. This less efficient process is mainly used for small batch production. With the popularity of large-capacity carbonated beverages, two-step production becomes an inevitable solution. The advantages of the two-step molding process are: PET bottles can be recycled; suitable for medium and large batch production; the degree of acetaldehyde is very low: soda X汨3 Micrograms, mineral water X ≤ 5ppm; bottle mouth no leakage; preforms will not be eccentric; preforms will not deform discoloration; in the case of the same mechanical strength, two-step PET bottles can be reduced by 10% -15% Weight; transport and storage costs are significantly reduced due to preforms (relatively small) rather than bottles to the beverage filling line; separation of preform production and bottle blowing process can optimize the production process and avoid wasteful production. Ability; product defective rate is extremely low.

The CHEN-PET system is a complete turnkey solution controlled by a central controller. The four components include: precision injection molding machine; needle valve control hot runner multi-cavity mold; removal robot with cooling function, needle-shaped preform conveyor belt; It also includes an auxiliary system consisting of a chiller, a desiccant dryer, and a mold temperature controller. The main components are: special injection molding machines, special molds for hot runner needle valve control, robots with independent cooling devices, needle conveyors with air-cooling devices, chillers, mold temperature controllers, and dehumidification drying systems.

The CHEN-PET system has 16-48 chambers to choose from, targeting global large and medium beverage manufacturers.
