I. Features of QJ-A4L-S1 Servo Automatic Blow Molding Machine

1. The preform transfer adopts a servo drive design, featuring high operating speed and high precision.
2. It has a wide application range for blow molding, capable of producing large-capacity bottles up to 2.0L, with strong capacity versatility.
3. It adopts suspended dense heating: the center distance between preforms is small, ensuring high heating efficiency and significant energy savings. The light waves of the heating tubes can penetrate the interior of the preforms, enabling the bottles to achieve optimal transparency and a perfect appearance after blow molding.
4. Equipped with a quick mold change design: operators only need to push the mold into the machine's mold installation slot for fixation, making mold change safer and more convenient.
5. The mobile operating platform facilitates daily operation and adjustment of the machine.

II. Comparison of Main Performance Features Between A4L-S1 Servo Blow Molding Machine and Conventional Automatic Blow Molding Machines on the Market

● Conventional Automatic Blow Molding Machines on the Market (Disadvantages)

1. The preform heating is designed as "inverted preform heating (mouth downward)". With this design, the preforms will bend when heated and softened. The larger the bottle capacity, the longer the preform, which makes it more prone to heat-induced bending and uneven thickness during molding inside the mold—seriously affecting bottle quality.
2. Preforms are inserted upside down on preform holders. These holders are large in size and heavy, resulting in a large center distance between preforms, slow movement speed, and significantly increased power consumption. Additionally, the heavy weight of the holders accelerates the wear of the transmission chain.

● A4L-S1 Servo Blow Molding Machine (Advantages)

1. The preform heating is designed as "suspended heating (mouth upward)". Benefiting from the natural downward force of the center of gravity, the preforms will not bend when heated and softened. The preforms can be uniformly molded inside the mold, thus ensuring bottle quality.
2. The preforms are transferred in a suspended manner without preform holders. This design achieves a small center distance between preforms, fast movement speed, and low wear.
