Space & Satellite Industry — process notes
Our integrated engineering department collaborates directly with space & satellite industry procurement and engineering teams: (1) 2D/3D CAD drawing review and material selection; (2) In-house mould and fixture toolroom fabrication; (3) Multi-axis CNC machining and high-tonnage hydraulic preforming; and (4) 100% batch metrology verification with full Material Test Reports (MTR). For our complete range of capabilities, explore our OEM & ODM custom manufacturing solutions (/custom-manufacturing).
Space & Satellite Industry — material scope
Components for space & satellite industry applications are produced from premium virgin and filled polymers (15–25% glass-filled, 25–33% carbon-filled, 40–60% bronze-filled, MoS2, PEEK, Delrin POM-C, UHMWPE, and technical ceramics). Raw resins are strictly tested for density (ASTM D792) and tensile strength (ASTM D4894) with batch traceability maintained for all production runs.
Space & Satellite Industry — tooling support
All tooling sets—including multi-cavity compression moulds and CNC machining fixtures—are designed and CNC-machined in-house from vacuum-hardened AISI D2 and H13 tool steel (58–62 HRC). Cavities are diamond mirror-polished (Ra ≤ 0.15 µm) to ensure sharp part release and high dimensional repeatability across multi-year OEM supply contracts.
Space & Satellite Industry — project selection
To request an OEM/ODM proposal for space & satellite industry parts or machinery, submit 2D PDF technical drawings or 3D STEP models, material requirements, annual batch quantities, and operating pressure/temperature parameters. Our engineering department provides comprehensive technical and commercial proposals within 24 hours.
Space & Satellite Industry — quality checks
Quality assurance protocols include digital coordinate measuring machine (CMM) dimensional verification, hydraulic pressure decay testing, dielectric spark breakdown testing (up to 80 kV/mm), and surface roughness profilometry (Ra ≤ 0.20 µm). Certified Material Test Reports (MTR) are provided with every production lot.
Space & Satellite Industry — commissioning
For machinery deliveries (Precision Powder Compaction Presses, Custom Engineered Hydraulic Presses), HEMSUN provides complete factory acceptance testing (FAT) at Dahegam prior to shipment, followed by on-site foundation anchoring, electrical cabling, hydraulic oil charging, and operator training by factory service engineers.
Space & Satellite Industry — export and lead time
Export shipments are packaged in multi-layer VCI moisture barrier bags and seaworthy wooden crates. Shipments clear direct from Gujarat via Mundra and Nhava Sheva (JNPT) container ports with Certificate of Origin, packing lists, and commercial documentation.
Space & Satellite Industry — maintenance and spares
Comprehensive spare part packages (hydraulic seal kits, replacement heating elements, PLC software backups) and technical support are maintained for all industrial installations.

Frequently Asked Questions
What capabilities does HEMSUN offer for space, satellite, and aerospace ground support?
HEMSUN engineers precision compression-moulded and CNC-machined virgin and filled PTFE components including cryogenic fluid loading seals, RF antenna feed-through insulators, and low-loss dielectric spacers. We also build custom hydraulic compaction presses for advanced composite panel compression.
How does HEMSUN approach future commercial space and planetary infrastructure hardware?
As commercial space systems transition from experimental R&D to serial hardware fabrication, HEMSUN's calculation-driven press engineering and clean fluoropolymer sintering capabilities provide the heavy compaction tooling and precision polymer seals required by aerospace fabricators building next-generation hardware.
Can HEMSUN manufacture cryogenic and vacuum-rated polymer seals?
Yes. We process high-density virgin and filled PTFE compounds that maintain elasticity and sealing integrity at cryogenic temperatures down to -200°C (-328°F) in vacuum environments.
