Discovery HR30 resin rheology and cure characterization

TA Instruments · Warpage, topography and stress metrology

Purpose: Obtain resin flow and cure data for material comparisons and mold-flow inputs during short-shot evaluation.
Technical approach: HR30 uses rotational and oscillatory rheometry to track viscosity and storage/loss moduli under changing temperature, shear and time.
Scope of use: For resins that can be sampled with compatible geometries and temperature control. Filled packaging materials require method validation.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Laboratory shear/cure data do not represent every mold-cavity flow or identify short-shot causes alone. Geometry, fillers, slip and sample heating affect results.
What to prepare
BLNKK suggests formulation/batch and filler information, sampling/storage history, process thermal profiles, short-shot samples and existing viscosity data.
Confirm with the supplier
Confirm geometries, gap, temperature control and measurement range; discuss cure-test repeatability and suitability of exported data for the flow model.
Public evidence: The current lineup lists HR30; the HR10/20/30 brochure provides an HR30 thermoset-cure example and model-specific tables.
