Built by a factory that runs what it sells
MAKERL Machinery — Jinan Makerl Machinery Co., Ltd. — thermal break assembly machinery since 2004.
Twenty years on one problem: the thermal break
MAKERL is a China-based manufacturer of thermal break assembly machinery for aluminum profiles — from single CNC knurling machines to fully automatic production lines running 120–240 profiles per hour.
Our equipment is produced under the TUSHUN CNC brand at our factory in the Qihe Dayu Industrial Park, Dezhou, Shandong. Over 20+ years we have supplied window and door fabricators, curtain wall processors and aluminum profile plants worldwide.
We sell machines the way engineers buy them: you send your profile cross-section drawings, we test knurling and strip insertion on real tooling, and only then do we quote a configuration. Installation, commissioning and operator training are part of the delivery, not an extra.
