WSRCNC's Material Selection Strategy
WSRCNC understands the specific material requirements for medical devices. When selecting machining materials, we comprehensively consider the component's function, operating environment, biocompatibility, mechanical properties, and cost-effectiveness. For the precision component in the image, here are several materials WSRCNC might employ, analyzed with their characteristics:
Aluminum Alloys
Characteristics: Aluminum alloys (e.g., 6061, 7075) are lightweight, have good thermal conductivity, are easy to machine, and are relatively low-cost. Their surface can be anodized to form a hard, corrosion-resistant oxide layer, improving wear resistance and aesthetics.
Applicability: The component in the image is very likely made from an aluminum alloy. In blood testing equipment, aluminum is commonly used for structural parts, brackets, internal functional parts not directly contacting the body, and modules requiring rapid heat dissipation. Its lightweight nature helps reduce overall device weight, and its good machinability makes creating such complex geometries possible. Anodized aluminum, with its increased surface hardness and corrosion resistance, can meet the needs of many precision parts not directly exposed to blood or reagents.
Medical Grade Stainless Steel
Characteristics: 316L stainless steel is one of the most commonly used materials in the medical industry, offering excellent corrosion resistance (especially in chloride environments), good mechanical strength, and biocompatibility. It is easy to clean and sterilize and moderately priced.
Applicability: If the component in the image needs direct contact with blood, reagents, or will be in a humid environment long-term, 316L stainless steel would be an ideal choice. Its corrosion resistance effectively withstands various chemical substances, ensuring long-term stability and safety. WSRCNC uses specific cutting parameters and coolants when machining stainless steel to avoid work hardening and ensure surface quality.
Titanium Alloys
Characteristics: Titanium alloys (e.g., Ti-6Al-4V) are renowned for their exceptional biocompatibility, high strength-to-weight ratio, and excellent corrosion resistance (particularly in biological environments). They are considered the "gold standard" for medical implants.
Applicability: While the component in the image is unlikely an implant, if it must withstand high stress or contact highly corrosive media within the blood testing device while requiring the highest level of biocompatibility, titanium alloy is a viable option. WSRCNC has extensive experience machining titanium alloys, overcoming challenges posed by their high hardness and low thermal conductivity to ensure machining precision and surface integrity.
PEEK (Polyether Ether Ketone)
Characteristics: PEEK is a high-performance engineering plastic with excellent biocompatibility, wear resistance, chemical resistance, high-temperature resistance, and X-ray translucency. It is an ideal lightweight metal alternative.
Applicability: If the component requires electrical insulation, light weight, or must operate in specific chemical environments, PEEK might be chosen. For instance, in fluid control systems, PEEK can be used for valve bodies, connectors, or pump components, leveraging its superior chemical resistance and low friction coefficient. WSRCNC can perform precision CNC machining on PEEK, ensuring its complex channels and hole structures meet design requirements.

Application in the Case: The component in the image features complex internal channels and multi-layered structures, which can be efficiently and accurately completed in one go using 5-axis milling. For example, the internal蜿蜒 paths and grooves of varying depths can be machined without dead angles through multi-axis interpolation, ensuring channel smoothness and dimensional accuracy. The toothed edge structure and holes can also be finished in the same operation, guaranteeing overall concentricity and positional accuracy.
CNC Turning
Process Description: CNC turning is primarily used for machining rotationally symmetrical parts. By rotating the workpiece and linearly feeding the tool, material is efficiently removed to create features like cylinders, cones, and threads.
Application in the Case: For a circular component like the one pictured, its initial disc shape is typically obtained via CNC turning. If the component requires highly concentric internal holes or shafts, turning is also a key process. WSRCNC utilizes high-precision CNC lathes to ensure the part's roundness, concentricity, and surface roughness meet medical-grade standards.
Precision Drilling and Tapping
Process Description: On CNC machining centers, high-precision drills and taps are used to perform precise drilling and tapping operations, creating various sizes of through-holes, blind holes, and threaded holes.
Application in the Case: The numerous holes on the edge and interior of the component, whether for fastening, locating, or fluid transfer, require extremely high positional and diameter accuracy. WSRCNC uses rigid machines and precision tools, coupled with strict program control, to ensure minimal positional deviation for each hole, smooth hole walls, and complete threads, meeting subsequent assembly and functional requirements.
Surface Treatment
Process Description: After machining, components may require surface treatments to enhance their performance. Common treatments include:
Anodizing: For aluminum alloys, forming a dense, hard, corrosion-resistant oxide layer that can be colored.
Passivation: For stainless steel, removing surface free iron and forming a stable oxide layer to improve corrosion resistance.
Polishing: Improving surface finish, reducing roughness, and lowering the risk of bacterial adhesion.
Application in the Case: The smooth surface of the pictured component likely underwent fine polishing or anodizing. These treatments not only enhance corrosion and wear resistance but also make the part easier to clean and sterilize, complying with medical device hygiene standards.
