Our battery box moulds are the ideal solution for battery manufacturing — built with lead-acid, lithium-ion and UPS options in mind. Our mould makers understand the importance of moulds tailored to each battery’s working environment and requirements.
Crafted with precision from high-quality steel, our battery box moulds hold ±0.08 mm wall uniformity across thin internal cell partitions and flatness on heat-sealing covers — guaranteeing the acid-resistance, electrical insulation, and pressure-test safety of your molded PP/ABS battery cases.

Materials and safety
| Steel | Role |
|---|---|
| 718H | Main cavity/core — uniform hardness & polishability for deep cell partitions |
| 1.2738 | High rigidity pre-hardened steel to prevent core shift under high injection pressure |
| 2344 (H13) | High-wear areas and long-life production |
These materials provide excellent insulation and withstand high-pressure and high-temperature testing, so the finished case keeps the battery safe and durable.

Battery case mould FAQ
What battery case moulds do you make?
Battery box and case moulds for lead-acid, lithium-ion and UPS batteries — automotive series (N40, N50, N70, N100, N120, N150, N200), UPS series (55AH, 90AH, 100AH), inverter IT500, and DIN55 and DIN66 series.
What steel is used for battery case moulds?
Steel 718H, 1.2738 and 2344, chosen for high rigidity, wear resistance, and dimensional stability so molded PP/ABS cases pass high-pressure leak testing — which is what guarantees the safety and durability of the finished battery case.
Which battery types do your moulds cover?
Automotive (N-series), UPS backup (AH-series), inverter (IT500) and DIN-standard (DIN55/DIN66) batteries, plus lithium-ion and lead-acid cases. Each series is tailored to the battery type and working environment.
Why does battery case mould design matter for safety?
A battery case must insulate and contain the cell and survive pressure and temperature. The mould controls wall uniformity, sealing surfaces and dimensional accuracy — so a correctly designed mould is what lets the case pass high-pressure and high-temperature testing.
Can you tailor a mould to a specific battery series?
Yes. We build moulds tailored to the battery type and its working environment — automotive, UPS, inverter or DIN — so the case fits the cell and the application precisely.
