This silo is constructed from stainless steel or magnesium‑aluminum alloy. Adopting a cylindrical design, it delivers excellent wind‑resistance and earthquake‑resistance performance.
A weighing module is installed at the silo bottom, which enables real‑time data feedback of raw material inventory.
Multiple auxiliary fittings are configured on the silo top, including inspection ports, maintenance walkways, exhaust vents, lightning arresters, anti‑fall protection devices and other components.
As the plastic processing industry upgrades toward automation and large-scale production, storage silos have gradually become the core unit of production line
materialmanagement. They not only ensure raw material quality and improve production continuity, but also help enterprises realize centralized management of
raw materials.
What advantages can storage silos bring?
1.Continuous material supply for stable production
They enable uninterrupted feeding for multiple pieces of equipment, reducing the time cost and error rate of manual material replenishment.
2.Pollution isolation for guaranteed product quality
With their airtight structure, sealed silos can effectively block external moisture and dust.
3.Workshop space optimization
Traditional raw material stacking occupies a large amount of workshop space, while large outdoor silos are installed outdoors to free up indoor production area. Raw materials are transported via fully enclosed pipelines without dust overflow, which both improves the workshop environment and reduces raw material waste.

Storage silos (storage bins / hoppers) are by no means simple material-holding containers. They act as the core hub connecting raw material conveying, production processing and quality control, and directly determine a factory’s material management efficiency and finished product yield.
Dongguan Niasi Plastic Machinery Co., Ltd. was founded in 2008. We are a national high‑tech enterprise integrating R&D, solution design, equipment manufacturing, project execution and after‑sales maintenance. For more than ten years, we have specialised in automated material handling for the plastics industry.
Based in Dongguan’s major manufacturing cluster, we have rich practical experience in on‑site project delivery. Our core product portfolio covers central material conveying systems, large‑scale outdoor raw material silos, dehumidifying dryers, metering and conveying equipment. We deliver one‑stop solutions for new‑plant overall planning, existing factory renovation and upgrading, and overseas export projects.
We have served over 500 domestic and international clients. Besides domestic sales, our engineered systems and equipment are exported in bulk to Japan, South Korea, Southeast Asia, the Middle East and other regions. We are a repeated exhibitor at CHINAPLAS. We possess full‑range engineering capacity for the design, manufacturing and overseas delivery of large clustered silo projects. Our in‑house technical team manages the whole scope, from equipment fabrication, control system development and steel‑structure accessories through to installation guidance. No complete project is outsourced, which ensures reliable project quality.
As the core storage component of central material conveying systems, Niasi large‑size plastic silos are backed by extensive hands‑on experience in outdoor silo projects for both domestic factories and overseas export assignments.
