FAQ – Frequently Asked Questions
Q1: What is the difference between hot pressing and Hi‑Pot testing in this machine?
Hot pressing applies controlled heat and pressure to shape the cell and eliminate wrinkles, ensuring uniform thickness. Hi‑Pot testing simultaneously checks for short circuits between anode and cathode by applying a high voltage (0‑500V) and measuring leakage current.
Q2: What is the typical production throughput?
Throughput depends on cycle time settings. With adjustable dwell time (0‑30 min) and test time (1‑5s), the machine can be optimized for R&D (longer cycles for process validation) or production (shorter cycles for higher throughput).
Q3: Can this machine handle different pouch cell sizes?
Yes. The worktable size is 350×270mm standard and customizable. Pressure (50‑2000KG), temperature (RT‑130°C), and dwell time (0‑30 min) are all adjustable to accommodate various cell sizes and materials.
Q4: What is the platen parallelism and why does it matter?
Platen parallelism is ≤±0.02mm, ensuring uniform pressure distribution across the entire cell surface. This prevents uneven shaping and ensures consistent cell thickness, which is critical for battery performance and safety.
Q5: Can the heating function be turned off?
Yes. The hard copper platens have temperature control with optional heating shut‑off when hot pressing is not required.
