Twin screw barrels are an important component in plastic extruders,
and they are used to melt, mix, and pump plastic materials through
the extrusion process. Nitrided screw barrels are a type of twin
screw barrel that have been treated with a nitriding process to
improve their surface hardness, wear resistance, and corrosion
resistance.
Nitriding is a heat treatment process that involves the diffusion
of nitrogen into the surface of the metal. This creates a hard,
wear-resistant layer on the surface of the screw barrel, which
helps to extend its service life and improve its performance in the
extrusion process. Nitrided screw barrels are particularly
well-suited for processing abrasive or corrosive materials, as
their surface hardness helps to resist wear and damage over time.
In addition to their improved wear and corrosion resistance,
high-quality nitrided twin screws can also provide other benefits
in the extrusion process, such as improved mixing efficiency and
reduced energy consumption. The precise design and manufacturing of
the screw and barrel can also have a significant impact on the
quality of the extruded product, making it important to work with a
reputable supplier who can provide high-quality components that are
custom-designed to meet the specific requirements of the
application.

Company Introduction
Our company Bloom(Suzhou) Materials Co., Ltd is a trading company
especially for oversea sales, but our factory OUZI technology is
specialized in the manufacturing of Replacement parts for Twin
Screw Extruder. So far has over then 5 years of research and
development production experience. Manufacturing Barrels,
Gearboxes, Overall Liners and Screw Elements for Twin Screw
Extruder. Our products cover all kinds of wear and corrosion
resistant spare parts such as screw elements , barrels, shafts,
plugs, couplings and so on. The screw diameter ranges from dia12.mm
to dia.350mm. We do not produce single metal barrels and screw
parts, but we also researched and produce bimetallic extruded screw
barrels, which will make the life time of the parts double or
triple increased. Our factory has strong technical force, excellent
processing equipment, advanced production technology, strict
inspection system and perfect after-sales service. My factory OUZI
technology is the main supplier of spare parts of Leistritz China.
We welcome all the friend oversea to contact and test my products,
we are sure that Quality proves everything.If You give us one
chance , we will return you inconceivable quality increased.
