Advanced Information

A subsidiary of Dalian Heavy Industry Equipment Group,
DXS made significant strides in 2025:
Localization: Its first 450,000-ton/year polypropylene
compounding and extrusion granulation line passed factory
acceptance in July, advancing China from a "follower" to a
"peer" in this field.
Globalization: Opened a Thailand service center in May
to enhance Southeast Asian market penetration; delivered a
custom ultra-precision four-roll rubber calender to Thai clients
in September.
Its high-precision, energy-efficient calenders have gained
wide recognition domestically and internationally. Sinochem’s Guilin base delivered outstanding
innovations:
Its 57-63 inch all-steel radial giant tire two-stage building
3 Guilin rubber R&D institute breaks machine won the "High-Quality Product" award, overcoming
chokepoint in five-compound extruder international bottlenecks in extra-large tire production via 4
technology invention patents.

A new electric-heated solid tire vulcanizer (energy
conversion rate >90%) was mass-delivered to leading tire
makers, enabling near-zero carbon emissions when paired with
green electricity.

5 Yiyang Rubber & Plastic Machinery
(Yiyang R&P) Excels in Technological
Innovation and Global Expansion

In July 2025, Guilin Rubber R&D Institute achieved
a breakthrough in key core technologies for five-compound
rubber extruders, ending foreign monopolies in high-end
green tire equipment. The equipment enables simultaneous in-
machine compound extrusion of 5 rubber materials, ensuring
high wear resistance and low rolling resistance—fully
complying with international standards such as the EU’s green
tire labeling system. Adopted by Michelin, Zhongce Rubber, Yiyang R&P achieved leapfrog development:
