Economical Storage Bin
Targeting mass raw material storage and centralized workshop warehousing scenarios, we develop the Economical Storage Bin with a large-capacity square cabinet design, fitting mass pellet storage for plastic granulation plants and recycled resource processing factories, a core supporting product actively promoted by overseas medium & large plastic processing enterprises and complete set equipment agents. Conventional round storage hoppers feature limited single-batch storage capacity, with multiple units occupying excessive workshop floor space. In contrast, the square three-dimensional structure of the Economical Storage Bin enables side-by-side stacking to maximize factory warehouse area utilization, with large-capacity cabinets storing thousands of kilograms of raw materials at once and drastically cutting frequent material replenishment labor.

The entire cabinet of the Economical Storage Bin is bent and welded from thickened 304 stainless steel plates with reinforcing ribs at four corners to boost cabinet load-bearing capacity and resist deformation under full material load. A widened feeding door on the top facilitates bulk feeding via forklifts and feeding machines, while the inclined diversion structure at the bottom enables complete emptying of pellets by self-weight without raw material residue waste. The fully sealed cabinet design isolates outdoor moisture, dust and insects, enabling partitioned storage of virgin materials, regrinds and color masterbatch without cross-contamination, adapting to rainy and humid production environments in Southeast Asia. Standard discharge ports are reserved on cabinet sides for direct connection to spiral feeding machines and mixing units to realize automatic material conveying. Multiple Thai recycled plastic factories have made bulk purchases of the Economical Storage Bin to build raw material warehouse zones.
As an original manufacturer with 13 years of production experience, we strictly control the plate thickness of the Economical Storage Bin and reject industry malpractices of thin plate cost-cutting. Cabinet load-bearing capacity and tightness are fully tested before delivery with service life far exceeding iron sheet storage bins at the same price point. The minimum order quantity is only one unit; overseas agents may purchase separately or combine with color mixers and storage hoppers for bundled sales to enrich supporting equipment categories. Every Economical Storage Bin undergoes full-load weight bearing and tightness testing before delivery, ready for direct warehouse use upon arrival without additional modification.

Factory Strength
Our factory is located in Rui'an, Wenzhou, Zhejiang Province, operating a 3,000 ㎡ modern standardized plant with an independent in-house R&D team continuously optimizing the load-bearing structure and diversion design of the Economical Storage Bin to boost storage capacity and reduce raw material residue. The factory maintains stable stock of standard storage cabinet units for short production cycles on regular orders, with faster delivery for repeat customers. The production workshop is fully equipped with CNC bending and laser welding equipment alongside weight bearing test benches. Every Economical Storage Bin undergoes full-load weight bearing trial operation after assembly to guarantee stable delivery performance. Global purchasers are also welcome to visit our factory for on-site inspections and prototype testing with raw materials.
Qualification Certifications

The full series including the Economical Storage Bin is manufactured in compliance with international machinery production standards ANSI and DIN, with workshop noise and sewage meeting global environmental regulations. Equipment can pass third-party on-site inspection and testing. Stainless steel plates and welding processes of the cabinets fully meet export standards with no certification barriers for export to Europe, America, Southeast Asia and the Middle East. Complete quality inspection records are delivered alongside goods, enabling overseas agents to provide test reports to local end customers for qualification audit demands.
After-Sales Service
All specifications of the Economical Storage Bin carry a unified 1-year complete machine warranty with dedicated after-sales specialists assigned to consult global customers. Free replacement of plate spare parts is provided for collision deformation during transport, and remote video one-on-one maintenance guidance is available for welding leakage during operation. For bulk cooperation agents, we provide free complete product promotional materials and equipment installation teaching videos, and support free delivery of small prototypes for customer testing. If concentrated common equipment issues arise among end customers after bulk procurement, we expedite plate spare part shipments and issue optimized rectification plans to minimize agents' after-sales operating costs to the greatest extent possible.
