On the eve of Christmas, KraussMaffei China announced some good news. Its section bar production line composed of two KMD 40KK linked with three co-extruding machines and exclusively customized for the YKK Group in Japan passed the trial run and acceptance check at one go during the three-day on-site debugging after 18 months of concerted efforts.
KraussMaffei China started to provide the section bar extruder for YKK in 2006 and so far it has supplied more than 40 extruders of various sorts to it, including KMD 40KK, KMD 60KP, KMD 75-32, KMD 90-32, KMD 114-26, KME 20-25 and KME 30-25.
In the past decade, to meet all the technical demands of YKK, KraussMaffei China has developed and customized various combined models for it. YKK’s new section-bar door and window frame production line has posed a new challenge for the R&D and design of extruders. Given the limited space in YKK plants, the two KMD 40KK main extruders and the three co-extruding machines must be placed together within the width of 3.1m, and the center-to-center distance between the two parallel main extruders is only 500mm. What’s more, KraussMaffei China needs to add the K-Tron metering and charging device to them and adopts the latest C6 control system for composite co-extrusion of PVC, PMMA and flexible PVC. No one has met such a demanding requirement for precision design in the business. Thanks to the support of German experts, KraussMaffei’s Chinese extrusion team has overcome various technological challenges, completed machine installation and passed the trial run at one go, with almost zero error made in the composite section-bar extruder production process from research and development to debugging, a unique design in the world for composite section-bar extruder.
At the site of equipment debugging, Mr. Sugahara, YKK technical director, thumbed up for the work done by KraussMaffei’s technicians. Cui Xiaojun, CEO of KraussMaffei China, said the cooperation with YKK was a typical win-win and he welcomed more clients to choose KraussMaffei’s customized engineering solutions. KraussMaffei China will serve clients with top extruding equipment and technologies in the world for win-win results.
