Hot sale servo control plastic Chemical pesticide bottle for injection blow molding bottle

Chemical bottles manufactured using injection blow molding are commonly used for packaging various chemicals,Injection blow molding is a process that combines elements of injection molding and blow molding to produce hollow plastic containers with precise dimensions and complex shapes. Here's an overview of the process:

1. Mold Preparation: The first step is to design and prepare the mold for the chemical bottle. The mold consists of two halves: the core and the cavity. The core forms the internal shape of the bottle, while the cavity creates the outer shape.

2. Injection Molding: In this stage, plastic resin pellets are melted in an injection molding machine. The molten plastic is injected into the cavity of the mold under high pressure, forming a solid parison (a tube-like structure with an open end).

3. Transfer to Blow Molding Station: After injection, the mold opens, and the parison is transferred to the blow molding station. The parison is held between the core and cavity halves of the mold.

4. Blow Molding: High-pressure air is introduced into the parison, causing it to expand and take the shape of the mold. The air pressure stretches the plastic material against the mold walls, forming the final shape of the bottle. The mold is designed to have the desired features, such as neck, threads, handles, or other intricate details.

5. Cooling and Solidification: Once the bottle has taken its final shape, it is cooled to allow the plastic to solidify and maintain its form. Cooling can be achieved through the circulation of cooling water or air around the mold.

6. Mold Opening and Ejection: After the cooling process, the mold opens, and the finished chemical bottle is ejected from the machine. Any excess material or flash is trimmed off from the bottle.

7. Quality Control: The produced bottles undergo quality control checks to ensure they meet the required specifications. This may involve visual inspection for defects, dimensional checks, and testing for leakage or chemical compatibility.

8. Packaging: Once the bottles pass quality control, they are ready for packaging. They may be labeled, capped, sealed, or placed in additional packaging materials
