HDPE Ball — Material Specifications, Engineering Data & OEM Supply
HDPE Ball is manufactured in Gujarat by HEMSUN ENGG. INDUSTRIES, providing tight dimensional accuracy and long service life in precision valve balls. Features premium high-density polyethylene (HDPE) compounding, void-free sintering, and precision CMM inspection.
Where HDPE Ball is used
Sealing and flow-control element in ball valves and pump check seats, where sphericity and surface finish decide shutoff tightness and operating torque.
Selected for aqueous, acid and alkali service at ambient temperature where light weight and low cost lead.
Supplied to drawing across the published range — Diameter
5mm to 310mm — industry-leading HDPE Ball size range; Material: HDPE (High Density Polyethylene) — with dimensional and material reports on request.

Manufacturing process
Our dedicated manufacturing cells produce HDPE Ball from premium high-density polyethylene (HDPE) powder stock. After uniaxial preforming in precision tooling, components undergo computer-monitored sintering cycles and diamond-tooled CNC profiling to hold exact drawing dimensions.
Material selection notes
Featuring FDA-compliant virgin high-density polyethylene (HDPE) or specialized filled compounds, HDPE Ball provides reliable sealing and low-friction motion under continuous operating temperatures up to +260°C. Filler additions enhance mechanical rigidity, wear resistance, and thermal conductivity for heavy mechanical loads.
How to specify your order
To evaluate HDPE Ball for your project, submit component PDF drawings and resin requirements. HEMSUN engineers review part geometry, recommend appropriate compression tooling or CNC machining approaches, and provide competitive commercial proposals.
Quality checks and inspection
Quality assurance for HDPE Ball includes 100% optical dimensional inspection, digital micrometer verification, CMM coordinate layout testing, and water displacement specific gravity checks according to ASTM D792. High-voltage spark testing up to 80 kV/mm verifies absence of internal pinholes and voids.
Ordering and export documentation
Domestic HDPE Ball orders ship with GST invoice and e-way bill where applicable. Export orders include commercial invoice, packing list, and certificate of origin from our IEC-registered works. Material certificates and dimensional reports attached for qualified pharmaceutical and OEM shipments Contact info@hemsun.com or sales@hemsun.com with your balls specification.
Export packing and lead time
Export customers receive complete logistics assistance for HDPE Ball, including FOB/CIF shipping quotes, express air courier delivery for prototype samples, and secure sea-freight container packing with full batch traceability.
Storage and handling
Storage and operating notes for HDPE Ball: Keep parts in sealed packaging at ambient room temperature. During equipment overhaul, inspect sealing lips for particulate embedding and replace components showing mechanical wear.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Diameter and sphericity are verified on calibrated gauges and the achieved grade is recorded on the inspection report; sintered density is checked per ASTM D792. A mill test certificate ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
Frequently Asked Questions
What is the largest HDPE Ball you manufacture?
We manufacture HDPE Balls up to 310mm diameter. Large HDPE Balls serve water tank float valves and large-bore water infrastructure check valves.
Are HDPE Balls suitable for potable water applications?
Yes. HDPE is FDA-compliant, non-toxic, and widely approved for potable water contact. Our HDPE Balls are suitable for water supply check valves, borehole pump check valves, and potable water system float valves.
Do HDPE Balls float on water?
Yes. HDPE has a specific gravity of 0.94–0.96 g/cm³ — less than water — so HDPE Balls float on water. Ideal for water tank float valves and liquid level control applications.
