SELL Lead acid battery positive spine grid die casting machines

April 22, 2022

Spine or Grid die casting machine used to make lead acid battery positive plate PB alloy spine. The pressure cast spine is better than gravity cast spine at the strength and crystal density. Details of PDC spine making machine:

Gravity casting be used to produce the spines many years ago. As its bad performance at the strength and crystal density, pressure die casting method used to instead of old casting method.In Europe, Pressure die casting method are widely used in lead acid battery positive grid manufacturing. The machine be named grid die casting machine, spine die casting machine or pressure spine die casting machine (PDC). Pressure die cast grids (spines) have more advantages than gravity cast spines at the strength and crystal density.

Our die casting machine advantages: stable, easy to maintain. The 700type grid high pressure casting machine with hydraulic mold clamping system, that can make double-spines at one shot.

Basic information of Battery spine/grid die casting machine:

  1. PDC Spine making machine application: to cast tubular positive plates of lead acid battery.

  2. Die casing lead alloy types: Lead antimony alloy, Lead calcium alloy.

  3. Spine PDC machine & Mold working period: Grid Mold 20days, Spine Die Casting Machine 30-40days

  4. Grid Mold material: H13

  5. Mold life: if everything goes well, 3-5years

Spine/Grid Pressure Die Casting Machine Performance & Features:

1. PDC grid making machine has 3 kinds control functions: manual, semi-auto, full-auto.

2. Die casting system drives by hydraulic station, pressure and injection speed can be adjusted.

3. Machine Hydraulic system is separated with die casting structure body. An independent hydraulic station gives more space of grid machine for assembly, maintain and repair.

6. Spine mould heats by electricity and cools by circulating cooling water. Mould temperature can be controlled and adjusted.

7. Mold steel material is H13, which has high strength and hardness.
