Applicational range
The Mflow is a modular, expandable device with which you can determine the melt mass and melt volume flow rate. Affordable to setup and gradually expand at any time.
You can optionally expand the Mflow with, for example, the pneumatic weight lifting unit or the weight pegging unit. The extrusion plastometers are equipped with heating elements that are specially adapted to the thermal conditions of extrusion barrel and device covers. This achieves a very good distribution of temperature over space and time.
Operation of the Mflow via a PC offers all the advantages of testXpert II: up to six devices per PC can be operated, the traceability of the results and their further processing with testXpert II LIMS is possible for a statistical check and as long-term statistics.

Applicational range
The Cflow is a compact instrument that allows rapid determination of the Melt mass flow rate of plastics. It is specifically designed for the processors of plastics that are less subject to extrusion tests and which do not require a connection to a PC.
The temperature control of the heating elements, the heating chamber and the extrusion barrel are perfectly matched to each other. The temperature is generated where it is needed. That ensures an excellent distribution of temperature across the full height of the barrel from the outset.
Rapid device control is facilitated by the test granulate contained in the scope of delivery. Addition control options are available for the temperature in the extrusion barrel, for the diameter of orifices and barrels with plug gages. An automatic or manual extrudate cutter, a separating door and a die plug are optionally available for the Cflow.

Read MoreQuick ViewZwick Cutting presses
Range of application
Zwick cutting presses are used to manufacture specimens from rubber, elastomers, foam rubber, plastic foils, and paper with a hardness up to 85 Shore A (according to ISO 868). The primary specimen shape classifications are as follows:
• Rectangular specimen
• Dumbbell specimen
• Round specimen
• Special specimen
Exceeding the given Shore hardness will greatly reduce the lifetime of the cutting blade and, in extreme cases,can result in damage.
