Custom Mill Sourcing & Certified Raw Stock Procurement

Specialty Forgings, Precision Extrusions, Exotic Alloys & Custom Plate Thicknesses.

Standard warehouse catalog sizes do not always satisfy mission-critical engineering designs. JYH Prototype leverages direct strategic partnerships with premier international and domestic metallurgical mills (including Aleris, Constellium, Thyssenkrupp, and Baosteel). We source custom continuous-cast billets, pre-machined net-shape forgings, customized extrusion dies, and rare superalloys (Inconel, Monel, Hastelloy, Kovar) with guaranteed delivery timelines.

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Custom Mill Sourcing & Certified Raw Stock Procurement.

What is the lead time for custom aluminum extrusion tooling? +
Custom extrusion die tooling is typically fabricated in 10 to 14 business days, with first-article extruded samples dispatched within 3 weeks.
When does it make financial sense to use custom forgings instead of billet? +
When production volume exceeds 50–100 pieces for large structural parts, near-net forgings save significant CNC cycle time and reduce material waste, offsetting tooling costs.
Can you source rare metals like Kovar or Inconel 718? +
Yes. We regularly procure Inconel 718/625, Hastelloy C276, Kovar, Invar 36, and Nitronic 60 directly from certified specialty alloy mills.
Can JYH hold buffer stock of raw materials for my annual blanket PO? +
Yes. We offer vendor-managed inventory (VMI) agreements, purchasing and warehousing your project-specific raw stock in Shenzhen with scheduled releases.
