Mold opening is a crucial process when making plastic bottles. It is the first step in the manufacturing process, key to quality and efficiency. This article will introduce the plastic bottle mold opening process in detail.

Mold Design

Firstly, the mold needs to be designed according to the product requirements. The mold is generally divided into two parts, one is the mold core and the other is the mold cavity. The core of the mold determines the shape of the inside of the plastic bottle, and the cavity of the mold determines the shape.

Mold design needs to formulate corresponding design schemes according to product size, shape, thickness, process and other requirements.

Mold making

After the mold design is completed, it needs to be made. Making molds requires the use of special materials and tools, usually steel or aluminum alloys.

During the production process, multiple processes such as milling, EDM, grinding, and polishing are required to ensure the quality and precision of the mold.

Install the mold

The finished mold needs to be installed on the injection molding machine. The injection molding machine is divided into upper and lower parts, the upper part is the fixed plate, and the lower part is the movable plate.

Install the mold on the upper fixed plate, and the lower movable plate needs to be connected with the oil cylinder of the injection molding machine.

Debugging the mold

After the mold is installed, the mold needs to be debugged. This includes adjusting parameters such as injection pressure, temperature, speed, time, etc. to ensure product quality and production efficiency.

During the debugging process, mold trials and inspections are required to find and solve problems.

Mass production

After the mold debugging is completed, it can enter the mass production stage. It needs to be checked and adjusted at any time during the production process to ensure product quality and production efficiency.

The whole mold opening process needs to pay attention to the following issues:

Design: The mold design needs to be carried out according to the product requirements, and the size, shape, thickness, process and other requirements must be carefully considered.

Manufacturing: Mold making needs to go through multiple processes, and each process needs to be carefully made to ensure the accuracy and quality of the mold.

Debugging: Mold debugging needs to carefully adjust parameters, test molds and check, and solve problems in time.

Production: The production process needs to be checked and adjusted at any time to ensure product quality and production efficiency.

In short, the plastic bottle mold opening process needs to go through rigorous design, manufacturing, debugging and production, and each link needs to be carefully operated and inspected to ensure product quality and production efficiency.
