FAQ

1. What is this product?

It is a precision instrument that compresses bulk powder into a fixed shape by applying a known vertical pressure, measures its volume change, and calculates the mass per unit volume.

2. What is this product used for?

It helps determine the maximum theoretical density achievable for powder materials during processing (e.g., before battery coating or during pharmaceutical tableting), enabling optimization of process parameters.

3. How does this product work?

Utilizing Hooke's Law and density formulas, it dynamically calculates the functional relationship between pressure and density. This is achieved by applying precise force and simultaneously measuring the height displacement of the powder layer within a mold of known cross-sectional area.

4. Why is this product important?

In the lithium battery industry, compaction density directly determines the battery's volumetric energy density. Insufficient density leads to inadequate capacity, while excessive density may impair electrolyte wetting. This instrument is the sole means to measure this critical balance.

5. How should users select the suitable configuration for different powder materials?

Configuration selection depends on powder type, expected density range, sample characteristics, and testing requirements. Battery electrode powders, pharmaceutical powders, and metal powders may require different testing conditions. QINSUN engineers can provide suitable configuration recommendations based on specific applications.

6. How does QINSUN ensure testing accuracy and provide technical support?
