Custom Material Balls — Material Specifications, Engineering Data & OEM Supply
HEMSUN ENGG. INDUSTRIES manufactures Custom Material Balls in Dahegam, Gandhinagar, Gujarat, India for high-performance industrial sealing, chemical processing, and valve OEM applications. Engineered from 100% virgin and custom-filled engineering fluoropolymer, featuring chemical inertness (pH 0–14), wide operating temperature (-200°C to +260°C), and precision CMM-inspected tolerances for domestic and export supply.
Where Custom Material Balls 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.
Common where an obsolete or single-source part must be reproduced from a drawing, a sample, or measurement of the worn original.
Supplied to drawing across the published range — Diameter
5mm to 310mm — widest custom ball range from India — with dimensional and material reports on request.

Manufacturing process
Our dedicated manufacturing cells produce Custom Material Balls from premium engineering fluoropolymer 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 engineering fluoropolymer or specialized filled compounds, Custom Material Balls 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 Custom Material Balls 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 Custom Material Balls 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 Custom Material Balls 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. Recurring supply schedules supported with fixed drawing revision and lot numbering for plant stores Contact info@hemsun.com or sales@hemsun.com with your balls specification.
Export packing and lead time
Export customers receive complete logistics assistance for Custom Material Balls, 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
Care and handling for Custom Material Balls: Protect machined sealing edges against impact during transit and staging. Do not exceed recommended compressive stress limits during mechanical flange tightening.
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
Can you manufacture a ball in a material not listed on your product pages?
Yes. Contact us with your material specification, diameter, tolerance, and quantity. We manufacture in virtually all engineering plastics, fluoropolymers, and elastomers — including specialty compounds, filled grades, and blended materials. Our material range covers PTFE, PEEK, UHMWPE, Nylon, POM, PP, HDPE, PVC, PVDF, FEP, PFA, ETFE, NBR, EPDM, Viton, Neoprene, Silicone, and more.
What is the largest custom ball you can manufacture?
We manufacture custom balls up to 310mm diameter in engineering plastics and fluoropolymers, and up to 310mm diameter in rubber/elastomeric materials — one of the largest custom ball sizes available from any manufacturer globally.
Can you reverse engineer a ball from a physical sample?
Yes. Send us the physical sample — specify the material if known (or we can advise from application context). We measure, draw, and replicate the ball precisely in the correct material grade. Useful for replacing obsolete OEM balls for valves and pumps without the original drawing.
What is the minimum order quantity for custom balls?
We manufacture from single prototype pieces. MOQ is flexible and depends on material, size, and complexity. Contact us with your requirement, material, and size for a quote.
