28 inch Luggage Vacuum Forming Machine

The 28-inch luggage box vacuum forming machine adopts vacuum adsorption forming technology. By heating to soften and applying air pressure for shaping, the plastic sheet is processed into a lightweight and sturdy luggage box shell. Here is a detailed introduction of the equipment:

I. Equipment Features

1. **Specification Configuration**

- Designed for production of 28-inch luggage boxes, equipped with special molds and heating platforms.

- Supports size adjustment, enabling flexible handling of various-sized box production tasks.

2. **Material Compatibility**

- Suitable for ABS, PC, PP and other thermoplastic engineering plastics. It possesses excellent impact resistance and strength, meeting the requirements for high-quality box shell manufacturing.

3. **Heating System**

- Utilizes an efficient heating device, which can be either electric heating or infrared heating.

- Supports precise control of temperature and time to ensure uniform heating of the plastic sheet and prevent local overheating or deformation.

4. **Forming System**

- Based on the vacuum suction forming principle, negative pressure is used to make the softened sheet material closely adhere to the mold, enabling rapid forming.

- An optional compressed air-assisted forming function is available, which improves the contour accuracy and surface quality of the product.

5. **Automation Control**

- Integrates PLC programmable control system to achieve full-process automated operation.

- Equipped with a touch human-machine interface, supporting parameter setting, operation monitoring, and fault diagnosis, with simple operation.

6. **Safety and Environmental Protection**

- Equipped with multiple safety protection mechanisms, including over-temperature protection and leakage protection functions, to ensure operational safety.

- Compliant with environmental standards, by optimizing energy consumption and reducing waste rates, it supports a green production model.

II. Operating Procedure

1. **Preparation stage**: Install and fix the mold, and clamp the plastic sheet onto the heating platform.

2. **Heating stage**: Start the heating system to uniformly soften the sheet to the molding temperature.

3. **Molding stage**: Turn on the vacuum system and use negative pressure to adhere the sheet to the mold; optional compressed air can be used to assist in the molding process.

4. **Cooling stage**: Shut off the heating, and quickly cool the product through air cooling or water cooling to achieve the final shape.

5. **Demolding stage**: After cooling is complete, remove the molded box shell from the mold box and perform edge trimming and quality inspection.

III. Equipment Advantages

- **Efficient Production**: Quickly respond to large-scale order demands, significantly enhancing production capacity.

- **Precise Forming**: Advanced molds and control systems ensure stable product dimensions and consistent appearance.

- **High Flexibility**: Supports various materials, thicknesses and colors of plastic sheets, flexibly meeting diverse market demands.

IV. Application Domains

 Mainly used in the luggage box manufacturing industry, it is suitable for the production of plastic shell products such as travel cases and trolley cases. It is an ideal equipment for achieving high-quality and lightweight luggage manufacturing.
