LIHAN screw and barrel are a symbol of success for plasticizing and output. All original screw geometries have been proven the test of time in the market based on different formulations, that's why our designers hold nothing back when it came to creating outstanding performance.
Strict design standards in manufacturing , heat processing and quality assurance ensure this unique pairing on a uniform plat form, this ultimately enhances the connection between screw and barrel.
We have ensured that every detail that goes into every aspect of a LIHAN product is perfection.
