The next step involves transferring the parison to the mold cavity, which is a critical stage in obtaining the desired bottle shape. TECH-LONG's blow molding machines employ advanced robotic systems for precise and efficient transfer of the parison to the mold. This technology guarantees accuracy, minimizing wastage and improving overall production efficiency.

5. Inflation and Cooling:

Once the parison is properly positioned inside the mold cavity, compressed air is introduced to inflate the parison. This inflation process forces the plastic against the mold walls, taking the shape of the desired bottle design. The machine maintains the required pressure until the plastic cools down, ensuring the bottle retains its shape and structural integrity. TECH-LONG's blow molding machines incorporate cooling systems that expedite the cooling process, further enhancing productivity.

6. Ejection and Trimming:

After the plastic has fully cooled and solidified, the mold is opened, and the bottle is ejected from the machine. TECH-LONG's blow molding machines employ efficient ejection mechanisms that quickly and safely remove the bottles from the mold. Additionally, any excess material, known as flash, is trimmed off using automatic trimming systems, ensuring a clean and presentable final product.
