Grid Casting Machine for Lead-Acid Batteries is a core technology in the production of automotive and industrial battery grids. The quality of the grid directly affects battery efficiency, durability, and electrical performance. For this reason, battery manufacturers require highly reliable, precise, and productive equipment.
The Automatic Grid Caster Model H22, developed by Degani Aldo Srl, represents one of the most advanced solutions available today for high-volume, high-precision grid production. According to the technical documentation, the H22 machine is designed to guarantee:
- Constant production quality
- Stable and repeatable casting conditions
- Minimal maintenance requirements
- Low vibration and reduced noise levels
- High reliability even in continuous operation
Grid Casting Machine Design and Operating Principle
The H22 Grid Casting Machine is a fully automatic system engineered for the casting of low-antimony and lead-calcium alloys, commonly used in modern SLI and industrial batteries. The machine features hydraulically driven movements for all main components, including ladle, mould, trimming unit, and grid ejection system. This hydraulic architecture ensures:
- Smooth and vibration-free motion
- Linear and stable molten lead flow
- Improved grid dimensional consistency
- Reduced casting scrap
Special attention is given to thermal control. The feeding pipe transporting molten lead from the pot to the dosing valve is electrically heated by Joule effect, allowing the system to reach working temperature in approximately 15 minutes while maintaining uniform heat distribution and preventing oxidation. An internal gas flame further protects the molten lead from surface oxidation, ensuring clean and defect-free grids.
Productivity and Automation
One of the key advantages of the H22 Grid Casting Machine is its high productivity combined with minimal manpower requirements. The system is capable of producing up to 20 grids per minute, depending on alloy composition and grid design. When configured in groups of four machines connected to a single melting pot, the entire production cell can be operated by only one operator, significantly reducing labor costs while maintaining high output levels.
The H22-PLC version integrates advanced automation and process control features, including:
- PLC control system
- Diagnostic alarms and error monitoring
- Storage of casting parameters for up to 20 different grid types
- Automatic cooling control
- Production counters and programmable timers for pre-heating cycles
These functions allow precise control of every stage of the casting cycle, ensuring repeatability and fast changeover between different grid formats.
Grid Size Flexibility and Industrial Capability
Thanks to recent mechanical upgrades, the H22 Grid Casting Machine is no longer limited to standard automotive grid formats. The reinforced hydraulic unit, enlarged mould holder, and upgraded ejector and cam systems allow the production of grids typically manufactured on industrial casting machines.
The system can now cast:
- Single grids up to 183 × 320 mm
- Double grids up to 183 × 155 mm
- Thickness up to 4 mm
A universal single trim-die covers trimming widths from 165 mm to 183 mm, further increasing flexibility and reducing tooling change time.
Technical Specifications of the H22 Grid Casting Machine
The standard installation data confirm the industrial robustness of the machine:
- Overall dimensions: 3650 × 1340 × 2300 mm
- Weight: 1350 kg
- Casting speed: 4 to 22 grids per minute
- Installed power: 17 kW (including feeding pipe heater)
- Compressed air: 5–7 bar
- Cooling water: 1–3 bar
- Power supply: 230/400 V – 50 Hz
These characteristics make the H22 suitable for both medium and large-scale battery plants, where stability, throughput, and energy efficiency are critical.
Advantages for Lead-Acid Battery Manufacturers
Implementing a high-performance Grid Casting Machine for Lead-Acid Batteries such as the H22 provides several strategic benefits:
- Consistent grid weight and geometry, improving plate uniformity and battery performance
- Lower scrap rate, due to stable lead flow and precise temperature control
- Reduced maintenance, thanks to hydraulic drives and vibration-free operation
- High operational safety, with integrated emergency systems and enclosed control panels
- Scalability, allowing multi-machine configurations for high-volume production lines
