What is Medical Casting
Medical castings are casting products specially used for various medical equipment, instruments and related medical facilities. They are usually made of biocompatible metal materials. Such as stainless steel and titanium alloy. They have specific mechanical properties and precise structures. To meet the needs of complex working conditions. Such as aseptic operation in medical scenarios.
As a professional foundry and supplier of medical equipment castings. JC Casting can accurately control the biosafety of materials. And the precision of products with many years of casting experience. And provide reliable support for various medical scenarios.
4 advantages of casting technology in the medical industry
The advantages of casting technology in the medical industry are significant. It can accurately match the special requirements of the medical field for parts.
1. Efficient molding of complex structures
It can directly cast complex parts that fit the human anatomy. Such as artificial joint surfaces and bone screw threads. It does not require a lot of subsequent processing. Avoids damage to material properties. It is especially suitable for the special-shaped design of implantable devices.
2. Material utilization and cost optimization
For high-priced materials such as titanium alloy and cobalt-chromium alloy. Casting can reduce waste. Increase material utilization by 30%-50%. It can reduce unit cost in batch production and ensure product consistency.
3. Meet high precision and surface requirements
Advanced processes such as lost wax casting allow micron-level tolerances. Smooth surfaces to be achieved. Reducing subsequent polishing steps.
4. Support personalized customization
Combined with 3D printing technology, customized molds can be quickly produced. Patient-specific parts. Such as skull prostheses. Can be efficiently produced to meet the needs of precision medicine.
Material selection for medical castings
The material selection for medical castings needs to comprehensively consider biocompatibility, mechanical properties, and corrosion resistance. Common casting materials of JC Casting are as follows:
1. Stainless steel
Low cost. Good corrosion resistance and processing performance. Moderate strength. The surface can be passivated to improve biocompatibility. Commonly used in surgical instruments. medical equipment housings. infusion pump components, etc.
2. Titanium and titanium alloys
Excellent biocompatibility. Low density. High strength. Strong resistance to body fluid corrosion. It is the core material for implantable castings, such as artificial joints, bone screws, heart valve stents, etc.
3. Cobalt-chromium alloy
Excellent wear resistance. High strength. Strong corrosion resistance. Stable biocompatibility. Especially suitable for scenes with long-term friction and load. Mostly used for friction surfaces of artificial joints, dental implant bases and other castings.
4. Magnesium alloy
It is degradable. It can be gradually absorbed in the body. No secondary surgery is required for removal. It has good biocompatibility. Its density and elastic modulus are close to those of bones. It is mainly used for short-term implantation of orthopedic fixation parts. Such as fracture screws and bone plates.
5. Precious metal alloys
Mainly gold, silver and platinum alloys. Excellent biocompatibility and stability. Strong anti-oxidation. Mostly used in dental castings. Such as crowns and bridges. Take into account both functionality and aesthetics.
JC Casting’s Casting Process
JC Casting primarily uses investment casting and centrifugal casting processes.
Investment Casting
Investment casting is one of the core processes of JC Casting.
Process flow: Make mold. Inject wax to get wax mold. Assemble into wax mold set. Apply refractory paint and sprinkle sand to dry into shell. Dewax at high temperature to get mold shell. Then pour in molten metal. After solidification, knock out the shell to take out the casting. Then clean and polish.
The advantages of this process are significant. It can produce castings with complex shapes and high dimensional accuracy. The surface quality is excellent. It reduces the workload of subsequent processing. It is especially suitable for making castings with delicate structures and extremely high precision requirements in the medical field.
Centrifugal Casting
Centrifugal casting is another important process of JC Casting.
Process flow: The mold is installed in the centrifuge. The speed is set according to the material and size of the casting. Then the molten metal is poured in. The centrifugal force evenly distributes it along the mold wall and solidifies it into a casting. After stopping the machine to take out the casting, it can be processed later.
The advantage of this process is that the molten metal can fully fill the mold under the action of centrifugal force. The casting has a dense structure and good mechanical properties. And for castings in tubular and cylindrical shapes, the production efficiency is high. It can ensure the uniformity of the casting. And meet the requirements of medical equipment for casting strength and stability.
Whether investment casting or centrifugal casting. JC Casting ensures that every medical casting meets high standards of quality.
