Production technology and application of high-quality medical mold parts

As the medical industry continues to increase its requirements for precision, safety, and durability, the quality of medical mold parts has become a key factor in ensuring the smooth production of medical devices and consumables. As a customized mold parts supplier focusing on medical, laboratory consumables and medical packing, we are committed to providing high-precision, high-durability mold parts to meet the needs of various medical equipment production. The following are several key factors we focus on in mold parts production.

Application areas: Medical molding parts are not only used in the production of injection molds, but also have a wide range of applications in the medical industry, covering a variety of needs from basic medical devices to high-precision laboratory equipment. The following are some of the main application areas be use:

l Precision injection molds: A large number of high-precision injection molds are required in the medical industry for product production, including various disposable medical products and high-precision medical parts. These molds have very high requirements for mold parts, such as mold core, mold insert, slider, core pin and cavity, especially in the injection molding process, which requires high precision and stability for a long time.

l Pharmaceutical packaging: Medical mold parts are also used in the pharmaceutical packaging industry, especially molds for the production of medicine bottles, medicine boxes, syringes, pharmaceutical containers and other products. With the increasing requirements for the safety and precision of pharmaceutical packaging, the quality of mold parts directly affects the smooth progress of the packaging process.

l Medical device manufacturing: In medical device manufacturing, mold parts are widely used in the production of syringes, needles, infusion sets, catheters, surgical tools and other products. These products require mold parts to have extremely high precision, corrosion resistance and long-term stability.

l Personalized medical equipment: As the medical industry develops towards personalization and customization, many small-batch, precision medical equipment and consumables require special mold parts. For example, customized implants, orthopedic devices, dental instruments, etc., all require high-precision mold parts to support their production.

l High-end medical equipment: For example, large medical equipment such as X-ray machines, CT scanners, blood glucose meters, etc., also require precision parts manufactured by molds. Medical mold parts play an important role in the production of these devices, ensuring the high performance and long-term stability of the equipment.

l Laboratory equipment production: In the manufacturing process of laboratory equipment, medical mold parts are used to produce various laboratory consumables and instrument parts, such as culture dishes, test tubes, centrifuge tubes, microtubes, specimen collection containers, etc. The manufacturing of these equipment requires parts to have precise dimensions and high temperature and chemical corrosion resistance.

l Laboratory equipment and consumables: including various types of laboratory equipment (such as microscopes, reagent bottles, culture medium containers, etc.) and disposable consumables. These products require mold parts to maintain accuracy during long-term use and withstand certain chemical corrosion and high temperatures.

Material selection: quality is the foundation

In the production process of medical mold parts, material selection is a crucial first step. We use high-quality steel and alloy materials, which can not only meet the medical industry's requirements for strength and durability, but also effectively resist corrosion and wear. Common materials such as stainless steel, Stavax, Unimax , S7, H13, aluminum alloy and special alloy materials can ensure that mold parts still maintain stable performance under high temperature, humidity and chemical substances.

Heat treatment: improve hardness and durability

In order to further enhance the mechanical properties of mold parts, we perform precise heat treatment on the selected materials. Through heat treatment processes such as quenching and tempering, the hardness and wear resistance of mold parts can be improved, and their service life can be extended. This is especially important for the medical industry, because medical molds need to have extremely high durability and stability under long-term and high-frequency use.

Coating: Improve corrosion resistance and functionality

Surface coating treatment of medical mold parts is also very important. We use advanced coating technologies such as nitriding, chrome plating, titanium coating and Balinit C coating to improve the corrosion resistance, oxidation resistance and friction resistance of mold parts. These coatings can not only effectively extend the service life of the mold, but also ensure that it will not react when in contact with drugs, liquids or other chemicals, ensuring the safety of medical products.

Processing: Precision and Efficiency

In the process of manufacturing medical mold parts, precision processing is the key to ensuring product quality. We use a variety of advanced equipment for processing to ensure that each accessory meets high-precision standards. Specific processing equipment includes:

l CNC Lathe/Milling: CNC lathes and milling machines are used to perform fine rotation and milling operations to ensure high precision of mold parts, especially in the processing of high-precision cylindrical surfaces and complex shapes.

l CNC Machining: CNC Machining are suitable for precise rotation and milling processing, which can meet the positioning requirements of mold accessories and ensure the accuracy and consistency of mold parts.

l Wire EDM: Wire EDM is used to cut mold parts with complex shapes, especially for some hard materials, It can accurately cut small holes, complex contours and precise shapes to ensure that the shape and size of each mold accessory strictly meet the design requirements.

l Electrical Discharge Machining (EDM): We are equipped with Sodick EDM, These EDM can perform precise molding and detail machining on materials with higher hardness, through the action of electric pulses, EDM can cut very fine and complex details, which is suitable for the micro-machining needs of medical molds.

l Grinding Machine: Grinding machines are used for fine surface processing, which can greatly improve the surface quality and finish of mold parts. Especially when high-precision mating surfaces and mirror effects are required, grinders can ensure extremely fine surface treatment and increase the service life and stability of the mold. For medical mold parts that require a high degree of cleanliness and precision, such as Ra 0.4, grinding machines are essential processing equipment.

Combined with these advanced processing equipment, we can ensure that each medical mold part meets strict quality standards while ensuring efficient production, meeting customer needs in terms of precision, durability, and improve the production efficiency of injection molds, extend the service life of molds, reduce time and produce costs, and allow customers to focus more resources on core processes, design and project management.

The manufacture of medical mold parts requires not only precise processing technology, but also high-quality materials, strict heat treatment and advanced surface coating processes.
