High precision requirements

Medical products usually have complex geometric shapes and fine structures, such as micro-medical device components, high-precision medical connectors, etc. Like the commonly used tips in laboratories, their size is small but requires extremely high accuracy to ensure the accurate amount of liquid absorbed at each time. For example, the size and shape of the needle tip and catheter need to be precisely controlled to ensure safety and effectiveness during use.

Strict hygiene standards

Since medical products are in direct contact with the human body or used in medical operations, molds must meet strict hygiene standards. This means that the mold material needs to be good biocompatible, smooth surface and easy to clean to prevent the growth and retention of bacteria and contaminants.

The particularity of material selection

In order to ensure the safety and reliability of medical products, the materials used in injection molds usually need to have high temperature resistance, corrosion resistance, wear resistance and other properties. For example, commonly used mold steels such as P20, H13, etc. can meet the requirements for long-term use of medical products after special treatment.

02. Key points of design and manufacturing

Mold structure design

Reasonable mold structural design is the key to ensuring product quality and production efficiency. For medical products, multi-cavity molds, hot runner systems or special release mechanisms may be required to improve production efficiency and product consistency. For example, when producing a large number of suction heads, multi-cavity molds can significantly improve production efficiency.

Optimization of cooling system

The precise cooling system can effectively control the mold temperature, reduce product deformation and internal stress, thereby improving product dimensional stability and quality.

Surface treatment technology

In order to improve the wear resistance and mold release performance of the mold, various surface treatment technologies are often used, such as hard chromium plating, nitriding, etc.

03. Quality control and testing

Size detection

Use high-precision measuring equipment, such as a three-coordinate measuring instrument, to strictly inspect the key dimensions of the mold to ensure that it meets the design requirements. Taking the indwelling needle as an example, it is crucial to detect key dimensions such as the angle of the needle tip and the inner diameter of the catheter.

Test mold and sample evaluation

After the mold manufacturing is completed, trial mold production is carried out, and the samples are subjected to comprehensive performance testing and appearance inspection, including physical properties, chemical properties and biocompatibility.

Monitoring during production

During mass production, the mold is regularly maintained and inspected to promptly discover and resolve possible problems to ensure the stability of product quality.

04. Development trends and innovations

Digital design and manufacturing

With the continuous development of computer technology, digital design and manufacturing technology are being used more and more widely in the field of medical injection molds. Through CAD, CAM software and simulation analysis, it is possible to predict possible problems and make optimizations during the mold design stage.

Micro injection molding technology

With the increasing demand for medical micro-device, micro-injection mold technology has developed rapidly. It is possible to produce medical parts with extremely small size and high precision, such as finer tips.

Application of new materials

Continuously explore and apply new mold materials, such as high-performance engineering plastics, ceramic materials, etc., to meet the higher requirements of medical products for mold performance.

In short, injection molds for medical products are an important support for the medical manufacturing industry, and their design, manufacturing and quality control levels directly affect the quality and safety of medical products. Continuously innovating and improving the technical level of injection molds is of great significance to promoting the development of the medical industry.

Application and development of molding integration in the medical field

In today's medical field, continuous innovation and progress in technology have brought better and more efficient medical services to patients. Molding integration, as an advanced manufacturing technology, is gradually playing an important role in the medical industry.

Molding integration has a wide range of applications in the medical field. In the manufacturing of medical devices, such as disposable syringes, infusion devices, etc., through integrated molding technology, the high precision and consistency of the products can be ensured and strict medical standards and hygiene requirements can be met.

For example, instruments for minimally invasive surgery have complex shapes and fine structures that rely on molding integration to achieve. This technology can create instruments with tiny channels and precision components, improving the accuracy and safety of the surgery.

In terms of medical consumables, molding integration has also shown significant advantages. For example, during the mold design and plastic molding of wound dressing, the breathability, water absorption and antibacterial properties of the material can be accurately controlled, providing an ideal environment for wound healing.

In the production of medical implants, molding integration is even more indispensable. For example, artificial joints, pacemaker shells, etc., it needs to be highly compatible with the human physiological structure, and at the same time have good biocompatibility and mechanical properties. Through the integration of molding, molds can be customized according to the individual differences of the patient, and implants that perfectly match the patient's body can be produced, improving the treatment effect and the patient's quality of life.

The development trend of molding integration in the medical field:

Material innovation trend: In the future, more new medical-grade plastic materials will be developed and applied to the molding integration process. For example, materials with better biodegradability are used for temporary medical auxiliary devices; materials with better comprehensive performance such as strength and toughness are used for load-bearing implants, etc.; smart materials such as temperature, pH, etc. Materials may also be introduced to better monitor and adapt to the internal environment of the human body.

Trends of digitalization and intelligence: 

The deep integration of digital technologies such as 3D printing and molding integration. On the one hand, 3D printing can be used to quickly create complex mold prototypes and then mass production; on the other hand, parameter monitoring and quality control in the production process will be more intelligent, and molding parameters can be adjusted in real time through sensors and big data analysis to ensure the product Stability and consistency of quality. At the same time, the development of intelligent design software will make mold and product design more efficient, accurate and personalized.

Trend of miniaturization and refinement: As medical technology develops into microscopic fields, such as nanomedicine, integrated molding technology needs to be able to manufacture more miniaturized and refined medical components and equipment. For example, micro-instruments for precise targeted drug delivery, more refined vascular stents, etc.

Green and environmentally friendly sustainable trends:

 In the production process, environmentally friendly production processes and material recycling models will emerge. For example, reduce energy consumption and waste emissions during mold processing, and recycle and reprocess medical plastic products.

Trend of multi-technology integration: Molding integrated technology will be integrated with other advanced manufacturing technologies (such as laser processing, plasma surface treatment, etc.) and biotechnology (such as cell culture technology, etc.) to expand application scenarios in the medical field. For example, in the manufacturing of implant surfaces, creating a microenvironment conducive to cell growth, etc.

The development of molding integration in the medical field also faces some challenges. First of all, the medical industry has extremely high requirements for product safety and quality, and the molding integrated production process must strictly follow relevant laws and standards, which puts forward strict requirements on the quality management system of manufacturing enterprises.

Secondly, the R&D cycle of medical products is long and the investment is large. The application of molding integrated technology requires close cooperation with the medical R&D team to conduct a large number of experiments and verifications to ensure the reliability and effectiveness of the product.

However, with the continuous advancement and innovation of technology, molding integration has broad prospects in the medical field.
