Process Introduction

Sandblasting creates a micro-rough surface to enhance osseointegration for medical devices, removing oxides and scale while providing a uniform matte finish. It is widely used for bone-contacting implant surfaces to improve long-term clinical stability.

Technical Specifications

Typical Applications

· Implants: Trauma plates, bone screws, spinal fusion cages, porous implant surfaces

· Instruments: Non-slip instrument handles, textured high-precision tool components

Process Introduction

Polishing reduces surface roughness to minimize wear, friction and tissue irritation, improving biocompatibility and aesthetic appearance for articulating surfaces and surgical instruments.

Technical Specifications

Typical Applications

· Implants: Hip/knee prostheses, femoral heads, acetabular liners

· Instruments: Osteotomes, forceps tips, minimally invasive shafts

Process Introduction

Electropolishing removes micro-burrs and surface contaminants, forming a smooth passive oxide layer to improve corrosion resistance and cleanability for surgical instruments and implants.

Technical Specifications

Typical Applications

· Implants: Small bone screws, non-magnetic components

· Instruments: Reusable surgical tools, endoscopic parts

Process Introduction

Passivation forms a protective chromium oxide layer to prevent rust and corrosion, enhancing biostability and meeting medical devices cleanliness standards.

Technical Specifications

Typical Applications

· Implants: Bone pins, auxiliary fixation devices

· Instruments: All reusable stainless steel instruments

Process Introduction

Laser marking provides permanent, non-damaging identification for full traceability (UDI, lot number, serial number) without affecting biocompatibility.

Technical Specifications

Typical Applications

· Implants: UDI marking, lot & serial number tracking

· Instruments: Manufacturer, batch & sterilization marking

Process Introduction

Heat treatment optimizes hardness, strength and fatigue resistance; relieves internal stress to avoid deformation in high-stress orthopedic parts.

Technical Specifications

Typical Applications

· Implants: Bone screws, intramedullary nails, joint stems

· Instruments: High-torque tools, durable shafts

Process Introduction

Anodizing forms a dense, protective oxide film on titanium surfaces, improving corrosion resistance, insulation and wear resistance. It also allows color coding for implant size identification in orthopedics.

Technical Specifications

Typical Applications

· Implants: Bone screws, intramedullary nails, joint stems

· Instruments: High-torque tools, durable shafts

Process Introduction

TiN (Titanium Nitride) coating is a hard PVD ceramic coating that provides excellent wear resistance, low friction and high hardness, widely used to extend the service life of orthopedic instruments.

Technical Specifications

Typical Applications

· Implants: Reusable drills, taps, reamers, forceps, osteotomes

· Instruments: High-wear auxiliary implant components

Process Introduction

DLC (Diamond-Like Carbon) coating offers ultra-low friction, high hardness and excellent biocompatibility, ideal for articulating implant surfaces and wear-prone surgical instruments.

Technical Specifications

Typical Applications

· Implants: Joint articulating surfaces, spinal implant sliding parts

· Instruments: High-wear minimally invasive tools, sliding components

Process Introduction

Electroplating deposits a thin metal layer to improve surface hardness, corrosion resistance, conductivity and appearance, complying with ISO 13485 for medical devices.

Technical Specifications
