The apparent density is determined to check manufactured and delivered moulding material. Knowledge of this density is a precondition for the calculation of loading chamber volumes of processing machines as well as of containers for storage and transport.
The apparent density is the ratio of mass and occupied volume. According to nature, the volume and thus the density considerably depend on the manner of pouring. For this reason the testing method was standardized; the PTL Density Test Funnel Device exactly complies to the relevant standards. In addition to the Density Test Funnel Device a precision balance is needed for determination of the mass.
PTL Density Test Funnel Devices have an electrically conductive connection between the funnel and the measuring cylinder to ensure potential equalization in case of electrostatic charges.
A Density Test Funnel Device can only be used for moulding material that can be poured from a specified funnel, i. e. powdery, granular or several short-fiber moulding materials. For long-fiber and shred-like moulding material, the apparent density is to determine in accordance with ((DIN) EN) ISO 61.
