How does Hasung Machinery ensure the quality and purity of metal powder produced by its atomizers?

Hasung provides a 2-year factory warranty for all industrial machines, covering manufacturing defects of main mechanical and electrical components. Consumable spare parts (crucibles, seals, filters, graphite parts) are excluded from warranty. Standard after-sales support includes 12–24 hour engineer response, free remote troubleshooting via video call, lifetime technical consultation and preferential pricing for spare parts after warranty expiry. On-site repair service is available upon request with separate service charges. Every machine is tested for 168 continuous hours before delivery to reduce on-site failure risk Hasung.

The custom chain line workflow follows 5 phases:

• Requirement collection: chain type, wire gauge, output speed, alloy material and factory layout.
• Concept & engineering design: mechanical structure, electrical control and process flow drawing.
• Prototype simulation and bench test for key forming & welding modules.
• Assembly and factory trial run with sample chain production to verify pitch, weld quality and consistency.
• Final adjustment, acceptance test and handover of operation manuals. We iterate and optimize the design together with clients until sample quality meets production requirements before mass manufacturing.

Hasung equipment complies with CE safety certification, ISO9001 quality management system, SGS inspection standards. Electrical, vacuum and pressure systems follow international industrial safety codes. All machines are fitted with multi-layer safety protection: over-temperature, over-current, over-pressure and door interlock safety cutoffs. We can provide certification documents and test reports for customs inspection and local factory audit for most export marketsHasung.

Vacuum pressure casting removes air from the mold cavity before melting and filling, eliminating gas porosity, bubbles and surface pinholes. Controlled inert gas pressure pushes molten precious metal to fully fill intricate fine jewelry patterns. The solidified castings have denser, finer and uniform grain structure, higher tensile strength and better ductility. It reduces surface defects, lowers material scrap rate and minimizes post-polishing work. Consistent casting results are achieved batch by batch, especially suitable for gold, silver and platinum fine jewelry productionHasung.

Yes. Hasung offers optional on-site installation, commissioning and hands-on operator training for overseas customers. Our senior engineers travel to the client’s factory to complete machine assembly, vacuum & electrical debugging, process parameter setting and operation training covering daily operation, recipe setup, preventive maintenance and common fault troubleshooting. Remote video training and online real-time support are provided free of charge as standard. On-site service fees including engineer flight, accommodation and daily allowance will be quoted separately.

Standard B2B payment term is 30% deposit upon order confirmation, 70% balance before shipment. For large custom production lines or high-value turnkey projects, we can negotiate staged milestone payments according to project progress. Letters of Credit (L/C) are acceptable upon prior review. All pricing is quoted in USD. Final payment terms are formalized in the sales contract.
