OEM Contract Manufacturing — Dedicated Capacity, Compression Tooling & High-Volume Parts Supply
HEMSUN ENGG. INDUSTRIES delivers comprehensive OEM contract manufacturing partnerships for global industrial equipment builders, valve manufacturers, semiconductor fabricators, and specialized fluid handling engineering firms. Operating from Dahegam, Gujarat, India, our vertically integrated plant provides dedicated hydraulic compaction capacity, custom toolroom die fabrication, cleanroom-standard sintering, multi-axis CNC machining, and stringent quality assurance under unified management.
Where OEM Contract Manufacturing is used
Sealing and wear ring locating and retaining pressure at a bore or shaft interface.
Common where an obsolete or single-source part must be reproduced from a drawing, a sample, or measurement of the worn original.
Key properties
Dedicated contract manufacturing cells with allocated press and CNC machining capacity
In-house toolroom for rapid die design, modifications, and long-term tooling maintenance
End-to-end supply chain integration
raw polymer sourcing, preforming, sintering, and finish machining
Bespoke private labeling, specialized export packaging, and scheduled batch call-off deliveries
Stringent IP protection, NDAs, and full traceability across all material and production logs
Flexible volume agreements from pilot line validation to high-volume recurring OEM contracts

Manufacturing process
HEMSUN's contract manufacturing protocol ensures strict reproducibility across production batches: (1) Contractual review, customer NDA execution, and tooling CAD modeling; (2) Tool fabrication from hardened tool steel with dedicated die numbers; (3) Resin formulation testing and controlled hydraulic pressing; (4) Calibrated thermal sintering with continuous chart recording; and (5) Multi-axis CNC machining and 100% CMM dimensional layout verification.
Material selection notes
We process a broad spectrum of virgin and compounded engineering polymers: Virgin PTFE (granular & fine powder), modified PTFE with reduced cold flow, glass-filled (15–25%), carbon-filled (25–33%), bronze-filled (40–60%), graphite, MoS2, virgin and carbon-filled PEEK, Delrin POM-C, and ultra-high-molecular-weight polyethylene (UHMWPE).
How to specify your order
When requesting an OEM contract manufacturing agreement, please provide 2D/3D component drawings with critical GD&T tolerances, annual usage forecasts, preferred delivery frequency (Kanban / call-offs), and packaging specifications. Our engineering leadership provides turnkey proposals within 24 hours.
Quality checks and inspection
Each contract manufacturing lot undergoes 100% QA checks: 3D coordinate measuring machine layout, surface roughness profilometry (Ra ≤ 0.20 µm), hydrostatic pressure decay testing, and batch ASTM Material Test Reports (MTR).
Ordering and export documentation
Domestic orders dispatch with GST tax invoice and e-way bill. Export orders include Certificate of Origin, packing list, commercial invoice, and complete QA inspection certificates dispatched direct from Gujarat ports.
Export packing and lead time
We provide comprehensive international supply chain support for global OEMs. Shipments are packaged in multi-layer VCI moisture barrier wrap and seaworthy wooden crates engineered for maritime container shipping.
Storage and handling
Tooling and dies created for contract customers are permanently stored, insured, and maintained in our climate-controlled die library at Dahegam for the lifetime of the supply contract.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Sealing faces are inspected for flatness and finish, thickness verified on calibrated gauges, and sintered density 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.
