I am asking anyone , what they could reccommend as suitable choice for some more small lab 25mm compound extruders (air blown compound pellet) and complimentry profile extruders (25mm) for smalll profile samples within the lab.I have been for 6 yrs involved in Rheology field in the pursuit of a range of mixed composites (ratios and formula formation) of virgin and or waste singular and or mixed polyfin families chelating nano fibre as comingled compositions. I've looking at facilitators and marrying agents, even autoclauving and solid state particle micronizing I am also looking later/sooner at later larger side fed direct and or indirect machines for both applications i;m also in pursuit of multi lamnination capability. I'm about to relocate my own lab )personal) to a Asian country. Brenton J. Burge ------------------

Brenton,I am a repsresntative for Randcastle micro extruders and some related technologies. I would be happy to discuss with you over email the excellent results obtained on these extruders. You may consider posting on more directly related catagories such as "Single Screw", "Profile", "Equipmwnt Wanted" an so forth. ------------------

Tom happy for any info and back up. Think you know were I'm heading.Quickly what is the budget for approx 25mm or are your machineries of different calibration. IP: Logged |

It is hard to say about the price. It sepends on what you want to do. A 1" extruder with minimal L  and minimal controls is likely $25-30K US. I recently sold a 3/4" line with film die and roll stack for $60K.What is really seling lines for Randcastle now is the new Patented Recriculator screw design. The screw combines low pressure mixing, extensional flow and recirculation and has been outperforming twin screw mixing at times. (Twin screw mixing is something I have some expertise in, so this comes as a surprise, but there at technical explainations for the results.) The recirculator is now gaining worldwide attention for it's ability to mix things such a carbon nano-tubes in small quantities. (Super expensive stuff at this point.)

Tom, one of the direction Im heading is high impact compounds using natural compound in nano molcule from where they are combined with Virgin and or waste regrind singular of mixed. Let keep open
the dialogue.
When I make the final decision I widh to almost get the machine of the shelf. I live now in Asia, already having moved (actually had a base there 6 yrs) and have had a lot to do with Korea and Chijna as well as Taiwan.
Like to expediatness.

In addition to Tom's good suggestions, and for comparison's sake, I'll mention the C.W.Brabender(South Hackensack NJ) line of small extruders---conical twins, and 3/4",1" single screws--L/D's up to 35:1,vented or not. For Asian markets, the parent Brabender Co. in Duisberg Germany would be the source of info.
These extruders can be hooked to a torque rheometer drive, or available as stand-alone "table-top" extruders.IP: Logged |

Two Beeps and Tom, Its like a novice amongst masters, thankyou to you both. I'm humble and appreciative to say the least. I have been biased towards conical twin screw functionality. In the past years I have been working on direct inline feed systems where one line usurps side fed barrel venting and where the fibre is more on the front end withthis side fed process so I dont get degredation. Essentially I would love it if I could take micronised cellulosic fibre and feed this direct into a machine along with that of small shredded polyfins (virgin or otherwise singular or mixed) Perhaps the method of feeding as I described needs some variant. One part of my push has been to find a system that does away with the reliance on compound masterbatch pellet as a direct manufacturing produciton option. Having said that I may need to bide my time and stay with the conventional systems for accuracy and integrity sakes. Mailleffer have gone a interesting way with this with the Connor Conex concept. What do you both/all have to pass on in respect to your thoughts. First thing first is the lab needs and and I greatly appreciate any direction to comparitives of manufacturers and their products. As Tom wrote each system has their own merit.
