Extruders, Downstream And Supply Inc

new and used plastics manufacturing equipment for the extrusion industry

Rupture Disc's

 All extruders must have a mechanical pressure relieving device - Rupture disc's are utilised at the head of the extruder at provide this and are subject to wear and eventual replacement.  Two styles are available with varing pressure ratings. 

    2 3/4 Inch Long Version - $59.95 Each                                   6 Inch Long Version - $129.00 Each

  

Replacement Breaker Plates

The main reason for most head clamp leakage involves wear and scoring associated with the breaker plate and replacement is often necessary to regain proper seal.  We custom manufacture breaker plates in 303 stainless steel to suit all brands of extruders - we will provide a drawing allowing you to provide all the critical dimensions.   

 Typical Extruder Sizes - 1 1/2 Inch @ $195.00, 1 3/4 Inch @ $225.00, 2 Inch @ $265.00, 2 1/2 Inch @ $295.00, 3 Inch @ $350.00, 3 1/2 Inch @ $395.00 and 4 1/2 Inch @ $475.00 

  

Melt Pressure And Melt Temperature Indication

We offer various retrofitable panel mount indicators with barrel mount transducers or immersion thermocouples to measure and indicate individual melt pressure, melt temperature or both in a combined unit.

 Unit shown offers both digital melt temperature and melt pressure in one panel mountable indication instrument and has a barrel mounted melt pressure transducer with built in immersion thermocouple (also includes 20 ft long communication cable) - PRICE:  $1,149.00

Unit offering just digital melt pressure indication - PRICE: $949.00      

  

Analog And Digital Meters 

 It is often desirable to have additional indicators of the extrusion process - good examples are that of heater loading (although EDS supplies ammeters for heater loading standard on every machine - this is often not the case with other suppliers), amp loading of motors, RPM's and Ft/Min indicators and we can provide retrofittable instruments that can be installed by your electrician.      

Analog Ammeters - Typically $59.95 each - provide scale range and power source (may require CT)  

Digital Meters - 0-10 Volt or 4-20 mA signal inputs and scaleable (may require CT if signal not available) - $129.00 each 

 

Encoder-Counter Packages

 There is often a requirement for accurate measurement and reaction within the extrusion process -  activation of a cut sequence or reaction as a result of reoccuring limit being reached.  EDS offers easy to program or pre-programed packages to assist in achieving your desired output.    

 Typical 'Digital Cut To Length' package show above - 1 ft/rotation rubber covered wheel mounted on 600 pulse per rotation encoder with communication cord to programmed panel mount counter offering output signal and reset to zero.  PRICE:   $950.00
