A complete instrumentation set for lead-acid and Li-ion battery case moulders — impact, tensile, VSP / HDT thermal grading, ESCR, density and ash — for reliability under acid, vibration and heat.
Battery cases sit under acid or electrolyte, vibration and heat for years. Failure is usually a crack — from stress, impact or environmental attack — and it means product recall.
This solution combines impact, tensile, thermal (VSP / HDT) and ESCR tests so battery-case moulders can qualify resins, verify batches and check finished cases. Real customers include Amara Raja, Exide, HBL Power Systems, Tata Green Battery and more.
Each card links to the machine that runs the test.
Notched Izod / Charpy impact — brittleness screen for PP, HDPE and ABS cases.
Tensile strength, elongation and modulus of the case resin and moulded strips.
Vicat softening point and heat deflection — critical for battery cases operating hot.
Environmental stress cracking of HDPE / PP cases in surfactant / electrolyte.
Verify incoming resin MFI batch by batch to prevent short-shots and weld-line weakness.
Grade verification and filler / regrind detection.
Percentage of ash / filler in the case resin at high temperature.
Accelerated ageing of finished cases to simulate long-term thermal exposure.
Battery-case tests span ASTM D256 / D6110 / ISO 179/180 (impact), ASTM D638 / ISO 527 (tensile), ASTM D1525 / D648 (VSP/HDT), ASTM D1693 (ESCR), ASTM D1238 / ISO 1133 (MFI), ASTM D792 (density), ASTM D5630 (ash) and ASTM D5423 (ageing). Every instrument is calibration-certified.
