EXTRUDER MAINTENANCE | MACHINERY
extrusion equipment is also becoming smaller - companies do not wish to keep large stocks so local spare part suppliers must have replacements on the shelf.
Entek developed the QC3 extruder (Quick
Change, Quick Clean, Quality Control) with quick change features for screw changes. The company claims QC3
twin-screw extruders are designed to
be mistake-proof. Screw elements can only go on the shaft one way, for example, and feature an alignment puck. Processors are said to be able to execute five-minute screw changes. The QC3
is
claimed to be particularly cost beneficial in colour compounding applications where compounders are producing numerous, small-sized batches of materials.

forces when it comes to new developments in the compounding and masterbatch industry, says Jürgen Sauer, Head of Business Unit Service at Leistritz. He says that ultimately customers will decide on which developments will be launched as products, but points out that increasingly all-en- compassing support programmes are being demanded, aimed at mechanics, electrics, control,
process technology and product quality. “Profitability and system availability must be maximised, with efficiency, quality and reliability determining success in the global market,” says Sauer. “These are exactly the reasons why lines must network, quality must be optimised and flexibility enhanced. Even older systems are being partly modernised in terms of technology and control. Spare part availability, as well as preventive maintenance, are becoming increasingly important. Customers want to analyse all their data in-house
