This one was de-risked in three steps: weekly production photographs from order to crating, a factory acceptance run on the customer's own CaCO<sub>3<\/sub> with the video and the parameter sheet sent over, and installation by our agent in Pakistan in the customer's language.

A <a href=\"\/machines\/co-rotating-twin-screw-extruder\/\">KTE-52B<\/a> \u2014 51.4 mm screws, 2\u00d7720 N\u00b7m, 55\u201375 kW, 80\u2013200 kg\/h \u2014 sits exactly in that band, and it is the size most first-time buyers should be looking at rather than the 75 mm machine they ask for.<\/p>\n<p>He bought a small twin screw extruder without coming to China first. That is not unusual, and it is not reckless if the order is structured properly.
