The injection molding technique is widely favored across the medicare industry for shaping disposable medical syringes. However, manufacturers need to follow medical standards to avoid fines and regulatory charges.
Disposable medical items are key components of the medical industry as they serve a crucial role in life-saving. Medical syringes are one of those pharmaceutical medical devices that are central to every medical operation worldwide. They need to be precisely produced with complete quality standards of purity. Disposable syringes are also a result of injection molding with precisely calculated amounts of molds and packaging of materials. The process involves a number of steps that ensure stringent quality control measures and maintain the complete functionality of the syringes for long-term use. Here will discuss the process of manufacturing medical syringes through the injection molding process. It will also highlight the key raw materials that play a crucial role in the large-scale manufacturing of medical syringes that meet the rising demands of the healthcare sector.
Syringe Production Process
Medical syringes and other disposable devices are the results of the injection molding process which is why the process is also referred to as medical molding. The production is divided into several steps with each phase ensuring the safe and reliable administration, from selection to assembly.
Design and Selection of Material
The first step of the medical molding cycle is the selection of design and material required. As syringes come in different sizes and capacities, it is necessary to choose the right design to meet the requirements standards, such as volume (1ml, 2ml, 5ml, or 10ml), needle compatibility, size, and ease of use. Design can be finalized only when the material that suits the selected size offers a compatible bond. The use of the right quality plastic is necessary to ensure the regulatory standards and prevent any chances of medical instability among patients. Choosing the right material also helps pharma manufacturers avoid unnecessary fines and regulatory charges.
Injection Molding as Per Medical Standards
The injection of medical grade plastics in predefined design die is the second step second step of the process. In this phase, the manufacturing of syringes begins by melting the plastic and injecting it into the mold cavity of the desired shape and size. The injected molten material imparts the syringe as per medical standards of manufacturing syringes. The injection molding method for syringe manufacturing is feasible as it facilitates large-scale production while maintaining consistency in dimensions and accuracy. This method is reusable and also maintains the tolerances and smooth surfaces of the syringes that after slight polishing are ready for assembly and packaging.
Assembly and Packaging
Packaging of medical syringes is a tricky process as the molded parts of the syringes need to be kept in a highly controlled environment to prevent any sort of contamination. To keep up with sterilization and purity measures, manufacturers precisely insert the plungers into the barrels of the syringes while keeping an eye out for any imperfection or defect. When assembled in a complete shape, the process of sterilization begins to maintain the integrity of the end product.
Quality Control
Another crucial phase is quality control and double-checking of requirements to ensure the accuracy of the manufacturing process. In this phase, the syringes undergo visual inspection from the core team. They measure the dimensions of the shape and perform various functional tests on the samples to validate the sterilization. Through close evaluation as per medical standards, the defect-free syringes are passed on for dispatch and use in the market under the supervision of core manufacturing bodies.
Compliance and Regulation
As syringes are medical components, regulatory compliance is key to aligning the market usage and manufacturing processes with the industry standards of security and fair use. The compatibility factor for medical use products is determined through Compliance and regulation checks to ensure that the medical use syringes are reliable, and safer for use for patients.
Raw Material for Medical Syringes Injection Molding
Different types of plastic are used in the medical syringe molding process and each type serves a unique purpose when it comes to metrics of standards and medicine use.
Polypropylene
Polypropylene is a thermoplastic which has a low viscosity and can be used in medical syringes injection molding process. It features an array of medical applications and can be packaged for future use.
Ethylene Oxide
Other than thermoplastics, gases, and chemicals also play a crucial role in the medical molding process. Ethylene oxide is one of them which is a flammable colorless gas that acts as a sterilizing agent in a very low amount to keep the syringes free from contamination.
Rubber gaskets
Rubber gaskets are components that join the cylinder and the plunger with complete precision so that no air or impurities can pass through. Different qualities of rubber with sterilization standards are used for this purpose.
Needles
Needles are crucial constituents of medical syringes as they offer different morphs and sizes. For a specific syringe with low volume and quantity, a thin needle is used while other syringes come with thicker needles for other uses in the medical sector.
Packing paper
During the assembly and packaging of syringes for industrial use, recyclable packaging paper is necessary to meet global standards and regulations. It also enhances the shelf life of the syringe and prevents contact of any impurity to syringe surfaces.
Wrapping it Up
The medical component molding process requires the use of highly specialized machinery and equipment to ensure quality. A sterilization plant, air compressor, and packaging machines are crucial to assemble the syringes as per medical standards. Testing equipment such as measurement tools, heat evaluation, and contamination checks are also part of the medical syringe molding process. Ultimately, injection molding comes into play in the manufacturing of medical syringes. Manufacturers use a combination of injection molding machines such as mechanical, hydraulic, and electrical to produce the best and optimal syringes.
