Cut implant procurement costs by 30–37% without compromising on quality, compliance, or delivery speed. Direct OEM partnership for US & European knee implant systems.
✅ ISO 13485 · ✅ FDA Registration · ✅ CE Marking · ✅ ASTM F75
For US and European medical device companies, the pressure to reduce costs while maintaining surgical quality has never been greater.
Western OEM prices have risen 22% in 3 years. High price of branded implants squeezes margins for hospitals and distributors.
Unreliable suppliers cause low quality surface finishes and dimensional deviations, leading to surgical complications.
High shipping costs and unpredictable ocean freight delays disrupt surgical schedules and inventory planning.
Most Asian OEMs demand 2000+ MOQs and 16-week lead times, killing flexibility for custom full knee reconstruction surgery systems.
We are Hebei Ruiyi Yuan Tong Technology Co., Ltd. (Rays Casting) — a high-tech enterprise specializing in medical-grade high-temperature alloy precision castings. We solve the price/quality/logistics equation.
Integrated high-temperature alloy precision casting + CNC machining. 50,000+ sq ft facility in Hebei, China. Short R&D cycles.
ISO 13485, CE, FDA compliant. ASTM F75 / ISO 5832-4 materials. Full traceability, 100% inspection.
Replicate existing designs or develop new Unilateral Tibial Plateau, Femoral Condyle, and Tibial Plateau systems.
Samples in 4–6 weeks. Production in 8–12 weeks. Low MOQ (500 units) to start. Flexible shipping (FOB, CIF, DDP).
Our core competency lies in manufacturing high-temperature alloy precision castings for orthopedic implants. Below are the standard and customizable options for full knee reconstruction surgery components.

| Casting Process | Investment Casting (Lost Wax) | Investment Casting + HIP | Investment Casting + HIP |
| Surface Finish (Ra) | ≤ 0.2 µm (standard) | ≤ 0.1 µm (polished) | ≤ 0.2 µm (standard) |
| Tolerance | ± 0.05 mm (CT 5-6) | ± 0.03 mm (CT 4-5) | ± 0.05 mm (CT 5-6) |
| Sterilization | Gamma / EtO (validated) | Gamma / EtO (validated) | Gamma / EtO (validated) |
| Certification | ISO 13485, CE, FDA 510(k) cleared | ISO 13485, CE, FDA 510(k) cleared | ISO 13485, CE, FDA 510(k) cleared |
🔬 *Custom geometries, porous coatings (plasma spray), and HA coatings available upon request for full knee reconstruction surgery systems.



"We switched to Rays Casting for our full knee reconstruction surgery line. 37% cost reduction and zero quality deviations in the first 10,000 units. Their OEM capability is world-class."

"The technical support for custom Femoral Condyle design was outstanding. Lead times were 4 weeks faster than our previous supplier. Highly recommend for OEM knee implants."

"Rays Casting solved our high shipping costs problem by offering CIF terms to Rotterdam. Consistent quality on Tibial Plateau components. We have doubled our order volume."


Our standard MOQ for full knee reconstruction surgery implant components is 500 units per design. For custom or complex geometries, we can start with 300 units after design validation.
We follow ISO 13485 and FDA 21 CFR 820. Every batch undergoes chemical analysis, mechanical testing, dimensional inspection (CMM), and surface finish verification. We provide full material traceability and Certificates of Compliance.
We are proud to hold ISO 13485:2016, CE Marking (MDR), and our manufacturing facility is FDA registered. We also comply with ASTM F75, ISO 5832-4, and ASTM F136 standards.
Absolutely. We offer full OEM/ODM services. Send us a sample or 3D model (STEP/IGES), and our engineering team will perform a DFM analysis and deliver prototypes within 4 weeks. We specialize in Unilateral Tibial Plateau, Femoral Condyle, and Tibial Plateau components.
We offer flexible terms: FOB (Tianjin/Shanghai), CIF (Hamburg/Rotterdam/LA), and DDP for qualified partners. Our logistics team consolidates shipments to reduce your freight costs. Average shipping time to US East Coast is 25 days.
We specialize in high-temperature alloy precision castings. Our primary materials are Cobalt-Chromium-Molybdenum (CoCrMo) per ASTM F75 and Titanium (Ti6Al4V) per ASTM F136. We also support UHMWPE components for the bearing surfaces.
