Die Head
The specially designed DKM basket die head and spiral die head for the DKM series single screw extruder, fits well with the DKM high speed vacuum calibrator and guarantees the high output with excellent article quality. The max producible pipe diameter isΦ1600mm.
* Regardless of material viscosity variation, widely applicable for HDPE/MDPE, PERT, PP/PP-R, PB, PS/ABS and HMW-PE pipe production, with reliable processing property.
* High output but rather low pressure drop and melt temperature.
* Small pipe stress due to the low melting pressure and temperature.
* Capacious and smooth runner reduces the pipe stress to the minimum.
* High quality ceramic heater with longer service life.
* Pipe with scratch-free smooth surface finishing.

Polyolefin pipe die-heads for pipe diameters ranging between 10 - 2 000 mm are part of the delivery package. Reifenhäuser was the world's first supplier of die-heads for 2 000 mm pipes, thereby significantly increasing the extrudable pipe diameter of the time a milestone that perfectly illustrates Reifenhäuser's key expertise.
Reifenhäuser uses spiral mandrel die heads for the extrusion of PE pipes. Coextrusion adapters for the extrusion- of 2 and 3 layered pipes are also supplied.

As the most influential brandname on extrusion die, owning 60% market share in China, we have been always dedicated to carrer on development of extrusion dies and correlative products
Features
Special flow channel design, sutiable for different raw materials, JCtimes has developed series of dies for PE PP PVC EVA foam products.
Independent temperature control system in lips ensures very identical temperature on the whole width, in order to get most proper expansion rates for different raw materials.
Equipped with the feedblock can produce the co-extrusion foamed products, in whiich surface layers are compact and the internal layer is foamed
Width adjustment system
According customer’s requirement to design various width adjustment system, include: external deckling system and inernal deckling system.
Features
Internal deckling system have reducing thick edge function, mainly use for coating extrusion line. Due to the special adjust requirement, the flow channel of the die also have special design.
Screw type external deckling can adjust the width on line and it working can save time, labour, and raw materials,
