Granule Storage Hopper
Targeting dedicated closed storage of pure plastic pellets and automated production line supporting demands, our self-developed Granule Storage Hopper is exclusively designed for virgin pellets, recycled pellets and color masterbatch pellets - standard supporting auxiliary machinery for injection molding, granulation and film blowing equipment, consistently purchased in bulk by plastic processing agents in Southeast Asia and the Middle East. General-purpose storage hoppers on the market accommodate both powder and pellets with small bottom inclination angles prone to retention of fine plastic pellets requiring manual cleaning after every material switch and wasting massive working hours. In contrast, the Granule Storage Hopper adopts a large-inclination conical bottom structure fully adapted to spherical and cylindrical plastic pellets for complete self-weight emptying of internal materials without residue waste.

The entire hopper body of the Granule Storage Hopper is integrally rolled and polished from thickened 304 stainless steel with smooth inner walls free of welding protrusions for unobstructed sliding of plastic pellets without jamming. Hopper plate thickness is upgraded with thickened material to resist long-term pellet friction and avoid metal debris contamination of raw materials. A detachable sealed feeding cover on the top isolates workshop dust and outdoor moisture to prevent pellet moisture absorption causing water ripple and bubble defects on injection-molded finished products. A standard universal discharge flange at the bottom directly connects to spiral feeding machines and all types of color mixing stirring equipment to realize automatic continuous feeding and eliminate frequent manual material replenishment. Multiple pellet processing factories in Vietnam and Malaysia uniformly match the Granule Storage Hopper across full production lines with over 50% reduction in workshop labor costs.
As an original manufacturer with 13 years of production qualifications, we refuse to cut plate thickness corners. Every Granule Storage Hopper undergoes pellet emptying testing before delivery to guarantee zero residual material retention. The minimum order quantity is only one unit; overseas trading companies may purchase separately for stocking or combine with color mixers and drying mixing machines for bundled sales to raise order total value. The equipment adapts to 220V/380V multi-national voltage matching feeding machines with no export adaptation barriers, perfectly fitting standalone small workshop matching and centralized feeding systems for large factories alike.

Customization Capabilities
Our factory provides full OEM/ODM customization services. The Granule Storage Hopper capacity, hopper height, discharge caliber and support frame height can be adjusted according to customers' workshop ceiling heights and main unit interface dimensions. Engineers can independently optimize structures based on production line layout drawings provided by customers, with free delivery of small prototypes for testing. Mixed shipments of different capacity Granule Storage Hoppers are available for large full-container orders. Customer self-owned brand LOGOs can be printed on the outer hopper body, and support frame colors and sealed cover styles modified on demand to help overseas agents build self-branded complete auxiliary machinery sets.
Packaging & Transportation

All exported Granule Storage Hoppers comply strictly with international export packaging standards. The inner and outer hopper surfaces are wrapped with thick waterproof and moisture-proof protective film; foam collision-proof padding is added to discharge flanges and hopper mouth edges, and the exterior is integrally reinforced with fumigated solid wood crates to avoid collision deformation and seawater rust corrosion during sea transportation. We are familiar with customs declaration and container loading procedures for major global ports with specialized staff tracking delivery progress throughout. If transport damage occurs upon goods arrival at the destination, we provide free replacement of plate and support frame spare parts and bear all losses entirely, eliminating cross-border logistics worries for overseas agents.
Payment Terms
Standard Granule Storage Hoppers adopt the payment scheme of 30% advance deposit and 70% balance payment before shipment. Customized modified storage hoppers require 50% advance payment and 50% balance payment prior to delivery. Tiered procurement discounts are negotiable for full-container bulk purchases. Settlement is supported via major globally convertible currencies such as US Dollars and Euros with formal trade documents issued for all fund transfers, meeting financial write-off requirements for overseas trading companies and factory purchasers. More flexible payment cycles can be negotiated for long-term stable repeat customers.
