As a global pioneer in orthopedic medical device manufacturing, our facility operates at the intersection of metallurgical mastery, biomechanical engineering, and clinical feedback. We specialize in providing custom OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) solutions for human and veterinary total hip replacement (THR) systems. Our infrastructure is equipped with state-of-the-art multi-axis CNC turning-milling centers, Citizen Swiss-type automatic lathes, high-speed VMC machinery, and class 10,000 (ISO 7) cleanroom packaging environments.
From initial CAD modeling and finite element analysis (FEA) to high-precision machining, plasma spray Hydroxyapatite (HA) surface treatment, and 100% optical coordinate measuring machine (CMM) inspection, we maintain rigid compliance with ISO 13485:2016, CE (MDR 2017/745), and US FDA regulatory standards.
OEM/ODM Strategic Value: We enable medical device brands, healthcare distributors, and veterinary surgical groups to shorten their product development cycle by 40%, guaranteeing full material traceability (ASTM F136 Ti-6Al-4V ELI, ASTM F138 SS316L/SS LVM, CoCrMo), zero-defect batch quality, and customized private-label laser marking and packaging.
Utilizing exclusively implant-grade Titanium Ti-6Al-4V ELI (ASTM F136) and High-Nitrogen SS LVM steel, ensuring maximum fatigue strength and biostability.
5-Axis milling and Swiss turning yield micro-tolerances (+/- 0.005mm) for critical taper joints (12/14 taper) and acetabular locking mechanisms.
Vacuum Plasma Sprayed Hydroxyapatite (HA) coating (porosity 30–50%, thickness 50–150 μm) accelerates rapid osseous integration and biological fixation.
Total Hip Arthroplasty (THA) is one of the most clinically successful procedures in modern reconstructive orthopedics. However, long-term survival of hip implants depends fundamentally on mechanical stability, stress transfer minimization, and low-wear tribological pairings. Our OEM/ODM stems are designed with optimized proximal cross-sections (double-tapered wedge or anatomical geometry) to achieve reliable proximal cortical engagement while decreasing distal stress shielding.
In cementless fixation systems, primary mechanical stability is governed by precise press-fit sizing against the prepared femoral canal. Secondary long-term stability relies on bone ingrowth or ongrowth into porous surfaces or Hydroxyapatite (HA) layers. The proximal coating encourages physiological load transfer, maintaining bone stock and reducing thigh pain associated with distal stiffness mismatches.
The wear of the bearing surface remains a primary factor influencing revision rates due to osteolysis driven by wear debris particles. Our artificial hip joint systems utilize high-purity CoCrMo (Cobalt-Chromium-Molybdenum) femoral heads or Zirconia-Toughened Alumina (ZTA) ceramic heads articulated against Highly Cross-Linked Polyethylene (HXLPE) or Vitamin E-blended HXLPE acetabular liners.

Veterinary Total Hip Replacement presents unique biomechanical challenges compared to human hip arthroplasty. Canine patients exhibit significantly higher quadrupedal activity levels, varying coxofemoral joint angles, and diverse anatomical range across breeds (ranging from small breeds requiring #4 stems up to large breeds needing #10 stems). Our veterinary THR systems (including BlueSAO-compatible geometry) incorporate specialized micro-acetabular cups and modular femoral components engineered to withstand high dynamic impact loads while treating severe canine hip dysplasia and coxofemoral osteoarthritis.
The global orthopedic implant procurement landscape is undergoing a structural paradigm shift driven by technological advances, stringent regulatory demands, and supply chain consolidation. B2B procurement managers and OEM brand owners must stay ahead of several emerging trends:
Direct metal 3D printing (Selective Laser Melting / Electron Beam Melting) allows the production of biomimetic trabecular structures directly integrated into acetabular shells, eliminating delamination risks of traditional coatings.
Utilizing CT scan DICOM data and AI algorithms, custom anatomical stems can be manufactured via automated CAM routines, delivering optimal fit for severe dysplastic femurs or complex revision cases.
Incorporating silver ion (Ag+) micro-particles or iodine-supported anodization into the porous matrix to reduce Periprosthetic Joint Infections (PJI) without compromising osteoblast cell proliferation.
As regulatory compliance under EU MDR (2017/745) and US FDA 510(k) becomes increasingly complex, global distributors are shifting away from fragmented trading suppliers to direct contracts with fully certified OEM/ODM manufacturers like us who provide comprehensive technical documentation, clinical safety data, and batch-by-batch material certificates.
