Silicone Baby Bottle Nipples Making Vacuum Compression Hydraulic Rubber Moulding Machine

Silicone Baby Bottle Nipples Making Vacuum Compression Machine/Rubber Mold Press

The Vacuum Compression Molding Machine is designed for rubber and plastic product manufacturing, utilizing a molded vacuum vulcanization process. It is particularly well-suited for producing various forms of seals. The molding and vulcanization take place in a vacuum negative pressure environment, allowing for efficient exhaust and minimizing the formation of bubbles.

This versatile machine comes in single-base and double-base configurations, offering options for safety enclosure and a clamping die mechanism, which can be chosen based on specific process requirements.

The main body of the vacuum vulcanizing press features a side plate structure, comprising upper beams, side plates, front and rear doors, door frames, hydraulic cylinders, plungers, and hot plates. This robust construction ensures precise operation and reliable performance during the vulcanization process. The Vacuum Compression Molding Machine is a valuable tool for achieving high-quality rubber and plastic products, especially seals.

The Vacuum Molding Machine operates using a fast air extraction method during the vulcanization process. Here's how it works:

1. Initial Air Extraction: During the idle time of the vacuum pump, the machine starts extracting the air from the vacuum box. This process creates a low-pressure environment inside the box.

2. Connecting the Vacuum Hood: When the air in the vacuum hood needs to be evacuated, the machine connects the gas in the vacuum hood with the low-pressure environment inside the vacuum box.

3. Balancing Gas Pressure: By connecting the gas in the vacuum hood with the low-pressure environment inside the vacuum box, the gas pressure in both areas is balanced. This balance allows for rapid air evacuation from the vacuum hood.

4. Achieving Rapid Pumping: As a result of the balanced gas pressure, the vacuum pump can quickly and efficiently remove air from the vacuum hood, facilitating the vacuum molding process.

This method of fast air extraction and gas pressure balancing in the vacuum hood and vacuum box enables the Vacuum Molding Machine to achieve rapid and effective pumping, creating a vacuum negative pressure environment essential for efficient exhaust and bubble-free molding of rubber and plastic products, especially seals.
