Lead acid battery positive Spine/Grid Production Line is used to produce the tubular lead acid battery positive spine. The manufacturing process involves spines casting and spines cutting. A positive spine die casting machine, spine die casting mould and a spine cutting machine be used in the whole production process.

The battery gird production line has 3kinds working methods:

1.Manual/Semi-auto spine production line

Lead alloy be feed into melting pot by manual. Electric heating tubes melting alloy in pot. Molten PB metal be inject into gird mould automatically. Operator picks casted grid from mold cavity. Use cutting machine to cut the gird runner and length to required dimension.

2.Automatic spine production line

Conveyor belt feeds PB alloy blocks to melting furnance. Grid die casting machine inject grids. Then a robot pick the grid up from mold cavity, and set it in a storage frame. Another robot move the grid to cutting machine, and got a finished lead grid part. Whole process is full automatically.

The Lead Acid Battery Positive Spine/Grid Production Line detail manufacturing process:

In spine manufacturing process, we suggest use manual production line. It is more cheap, fast and easy maintain than automatic line.

1.Lead alloy be melted in pot.

Electric heating tubes used to melt PB alloy. First time, we need used burner to melt the Lead alloy blocks to avoid the damage of electric heater. Or, ladling molten alloy into machine pot from centralized smelting furnace. Melting temperature can be controlled and adjusted. A dust exhaust hood used to remove waste gas.

2. Grid mold move down and connect with nozzle.

A longer hydraulic cylinder push and pull the grid mould up and down along the slant guide rail. Mold locking mechanism clamp the grid mold. Mould gate connect with injection nozzle tightly.

3. Molten PB alloy be injected into Spine/Grid mold.

A hydraulic cylinder with a plunger be set above the furnance. Plunger push molten lead alloy through gooseneck mechanism to nozzle and be inject into mold cavities.

4. Grid mold move up, opening mold.

Longer cylinder pull the grid mold up, mold-opening mechanism open the movable die half.

5. Worker picks casted spine from mold cavities.

Manual grid making process, operator pick casted spine up from mold cavity. Clean and lubricate mold cavity.

6. Cutting machine cut the runner and to cut the spines as per technical requirement.

Casted grid be set in cutting machine. A fixture hold and limit the grid. Cutter move down, runner way and extra ribs be cut, got finished spine.

7. Another worker inserts spines into battery tubular plates.

The finished grid be insert into tubes by manual.

The PDC Spine making machine application:

PDC-pressure die casting machine, which used to cast tubular positive plates grid/spine for lead acid battery. High pressure makes the gird with high-density. That allows the casted grid has good performance.

Which lead alloy types can be used to produce battery positive plate spines?

Die casting lead alloy types: Lead antimony alloy, Lead calcium alloy.

Spine PDC machine & Mold working period:

Grid Mold 20days, Spine Die Casting Machine 30-40days.

Grid Die Casting Mold Material and Life:

H13 or same type mold steel material.

Mold life: 3-5years
