In PVC processing, the auto-stop for semi-automatic rinsing of the extruder and die has repeatedly proven itself. This process is triggered by the operator in the extruder’s control system. In this process the feeding of the production material is stopped, and the melt pressure at the screw tip is monitored.
Pulsation-free passage through the PVC die - battenfeld-cincinnati
Pressure fluctuations are substantially reduced with the result of a low-pulsation melt flow passing into the forming die. The final results are better semi-finished product quality with fewer dimensional fluctuations and consequently optimal utilization of the material.
battenfeld-cincinnati produces largest melt gap for pipe extrusion
2019年10月10日 · At its booth B 19 in hall 16, battenfeld-cincinnati Germany GmbH, based in Bad Oeynhausen, will present as a world premiere the largest adjustable melt gap for a pipe extrusion die, with which a diameter range from 1,200 to 1,600 mm can be covered without nozzle change.
A cavity pressure sensor is a pressure transducer installed in the mold, which is able to measure the melt pressure inside a certain cavity. The peak value of the cavity pressure is directly related to the part filling level, and this in turn to the final dimensions of the molded part.
New melt pressure transducer for low pressure extrusion
2019年2月20日 · True-Melt-Sensor Nominal Controls Inc. Toronto, Ontario introduces True-Melt™ pressure transducers designed for low pressure extrusions.
They range in pressure from plastic 0-500 in the PSI 0-20,000 with temperatures outputs range 0-10 V (at 70-750°F. PSI Typical mV/V, 4-20 mA, 0-5 V, or transducer scale output). APPLICATION Plastic materials are formed to shape by a process defined as extrusion. This is accom- …

Next-generation extruders from battenfeld-cincinnati have long since established themselves in the market. High output rates at low screw speeds, effective melting performance with low melt temperatures plus a reduced pressure profile and consequently less wear on machines – these are the benefits provided by the high-speed solEX NG series.
Battenfeld-Cincinnati adds smaller unit to solEX NG line
2022年11月30日 · Steady flow measures melt pressure in front of the extrusion die and constantly adjusts the screw speed to eliminate fluctuations. The company has applied for a patent. The German machinery manufacturer also unveiled a new pelletizing extruder series for PVC, the aglomEX, suitable for both dry blend and recycled PCR material.
Melt Pressure Transducer | Extruder Pressure Transducer
Offers melt pressure measurement in ranges from 0 - 250 through 0 - 10,000 psi at accuracies down to 0.25% and process temperatures up to 700°F. The PT460E Series transducer is a ±0.5% sensor ideal for melt pressure applications.
PT435A High Accuracy Melt Pressure Transducer for Space
PT435A High Accuracy Melt Pressure Transducer for Space Restricted Areas. Model PT435A provides the high accuracy of models PT420A and PT422A but can mount in extremely tight spaces. The specially designed process connector uses a free - spinning jam nut and an exposed capillary tube capable of 1/16" bend radius.
