Mobile Toilet Rotomolding Equipment

Mobile toilet rotomolding equipment, represented by the 3.0m diameter oven equipment produced by Xuri, is the core equipment for producing lightweight and recyclable mobile toilets. The following provides an explanation from three aspects: equipment principles, application advantages, and technical characteristics:

1. Compatibility of Rotomolding Process with Mobile Toilet Production
Rotomolding (rotational molding) is a process that uniformly attaches plastic raw materials to the inner wall of a rotating mold through heating and then melts and forms them. This process does not require high-pressure injection or extrusion, has low mold costs, and can produce hollow structures, making it particularly suitable for manufacturing large and complex-shaped mobile toilet shells. Its advantages include:

• Lightweight Design: By selecting high-strength plastics (such as polyethylene) and optimizing wall thickness, the main body of the toilet can be reduced in weight by 30%-50%, facilitating transportation and installation.
• Recyclability: Plastic materials can be melted and reshaped, with a recycling rate of over 90% after disposal, meeting environmental requirements.
• Integrated Molding: Single-step molding can complete components such as the toilet shell and water storage tank, reducing assembly processes and improving sealing and durability.

2. Core Parameters of the 3.0m Diameter Oven Equipment
The 3.0m diameter oven produced by Xuri is a typical piece of equipment for rotomolding mobile toilet production, designed based on the following technical logic:

• Mold Compatibility: The 3.0m diameter can accommodate standard mobile toilet molds (usually 2-3m long and 1.5-2m wide), supporting the production of 1-2 toilet units per cycle.
• Temperature Control: The oven uses zoned heating (temperature range 150-350°C) to ensure uniform melting of plastic raw materials and avoid material degradation due to local overheating.
• Rotation System: The mold rotates bidirectionally at a speed of 5-15 revolutions per minute, allowing the plastic to uniformly cover the inner wall of the mold under centrifugal force, forming a shell with uniform thickness (usually 3-8mm).
• Cooling System: After molding, rapid cooling is achieved through forced air or water cooling, shortening the production cycle (approximately 4-6 hours per cycle).

3. Technical Optimizations in Equipment Application
To improve production efficiency and product quality, the 3.0m oven equipment is usually equipped with the following technologies:

• Multi-directional Mold Tilt: By adjusting the tilt angle of the mold (0-45°), the plastic flow path is optimized, reducing defects in thin-walled areas.
• Automated Control System: Integrated monitoring of temperature, rotation speed, and time parameters enables digital management of the production process, reducing human error.
• Energy-saving Design: Heat recovery devices are used to preheat raw materials with residual heat, reducing energy consumption by 20%-30%.

Currently, this equipment has been widely used in the mass production of mobile toilets for scenic spots, construction sites, and other scenarios. Its lightweight and recyclable characteristics significantly reduce the full lifecycle cost, making it a mainstream solution for manufacturing environmentally friendly public facilities.
