Working Principle
The molding powder is supplied to the weighing system through the feeding mechanism. Once the preset weight is reached, the feeding process is automatically controlled by the PLC system.
The accurately measured material is then discharged into the designated container or transferred to the next stage of production. Operators can adjust the target weight and other operating parameters through the touchscreen interface.
This automatic process reduces dependence on manual weighing and helps improve material consistency throughout the production process.
Application
This weighing and dosing equipment is commonly used for the preparation of molding materials for:
- Melamine plates
- Melamine bowls
- Melamine trays
- Melamine cups
- Melamine dishes
- Other compression-molded tableware
- Urea moulding compound products
It is particularly useful for factories requiring repeatable powder portions and efficient material preparation.
Advantages for Manufacturers
Improved Production Consistency: Accurate material portions help keep the amount of molding compound consistent from one production cycle to another.
Reduced Manual Labor: Automatic weighing and discharge operations reduce repetitive manual weighing work and improve overall workflow efficiency.
Easy Parameter Adjustment: The PLC touchscreen system allows operators to change weighing settings according to different products and production requirements.
Adaptable to Different Products: The configurable weighing range makes the equipment suitable for products with different sizes and molding material requirements.
Easy Production Line Integration: The machine can be customized to match the layout and operating requirements of an existing melamine tableware production line.
