Silicone, a unique chemically inert compound similar to synthetic rubber, offers exceptional mechanical properties and compatibility with biological tissues. With its exceptional flexibility, silicone is the go-to medical-grade plastic polymer for manufacturing a wide range of products and devices, such as catheters, connectors, and tubing.
Polystyrene (PS)
Polystyrene (PS) is a high-quality engineering-grade plastic that’s not as flexible as others, but it has exceptional mechanical properties and is compatible with body tissues. Polystyrene offers excellent dimensional stability, making it ideal for creating critical medical components like petri dishes, culture trays, and diagnostic parts.
Compliance With Industry Standards
Medical injection molding ensures that the produced components meet all necessary regulatory requirements set by the FDA.
Cost Effectiveness
Injection molding is not only automated, but it also significantly reduces labor costs. With computer-controlled precision, each part is efficiently produced, resulting in lower costs per unit.
High Precision and Accuracy
Injection molding guarantees tight tolerances and dimensional accuracy, which are crucial in the medical field. With injection molding, even the smallest deviations can be avoided, reducing the risk to patients.
High Volume Reproducibility
When it comes to medical products, such as syringes, gloves, and masks, the ability to produce high volumes with consistency is crucial. This is where injection molding excels. With this technique, once the mold is created, thousands of identical parts can be produced without the need for maintenance.
Collaborating closely with leaders in medical technology, we transform innovative concepts into solutions that enhance advanced medical treatments.

☼ Advantages of Plastic Injection Molding for Medical Applications
Medical Solutions for Plastic Injection Molding Infographic
Compared to other plastic manufacturing processes, plastic injection molding offers a number of clear advantages, especially when working with a knowledgeable and skilled injection molding partner. These benefits encompass the following:
Compliance with industry standards/regulations: Engineering-grade plastics can be used in plastic injection molding operations to create parts that enhance patient safety and comply with FDA guidelines. Additionally, these medical plastics parts require less finishing work than metal ones, resist contamination, and maintain an easy-to-clean surface.
Mechanical properties: Injection molded parts made from engineering-grade plastic resins exhibit exceptional mechanical properties, including tensile strength, high-temperature resistance, and tolerances comparable to those of metal parts.
Flexibility: By working with uncolored virgin material, we can customize each part color to meet the exact needs of the customer.
High volume repeatability: In medical device manufacturing, a few millimeters or microns can differentiate between a functional component and a failed component. Yongchao—must have the skills to produce high-precision, high-accuracy components in both small and large quantities.
☼ Selection Considerations for Medical Grade Plastics
Strength: The selected material should provide the level of strength needed to support the application.
Industry standards: It should fully comply with FDA and medical industry standards relevant to the final component.
Operating conditions: The material should accommodate all of the requirements of the application environment. For example, if the finished component part will be subjected to chemical or high heat (e.g., in sterilization operations), the material should offer adequate chemical and temperature resistance.
☼ Advantages of Injection Molding for the Medical Industry
Cost Efficiency
While creating tooling requires a significant amount of time and money upfront, injection molding is extremely cost-effective at high volumes. Bulk injection molding will spread the tooling cost across thousands of parts, lowering the overall cost-per-part.
A Wide Range of Compatible Materials
Compared to all other manufacturing processes, injection molding has one of the widest material selections. While some materials aren’t suitable for use in the medical industry, there are still many materials capable of meeting the industry’s various requirements and regulations.
High Levels of Accuracy
Injection molding is known for its accuracy and repeatability, making it perfect for the medical industry, where the slightest mistake can cause a part or device to fail. Injection molding allows companies to quickly create hundreds or thousands of identical parts while providing exceptional accuracy and adhering to tight tolerances.
Superior Strength, Durability and Mechanical Properties
Injection molded parts are quite strong and durable. They may also be resistant to vibrations, impacts, and harsh environments. Some are resistant to heat, meaning they can be easily and repeatedly sterilized via an autoclave without suffering any damage.
☼ Types of Injection Molding Processes for Medical Devices
Design assistance: Our team of engineers can help you create the perfect design for your parts.
Plastic (Regular) Injection Molding
Plastic injection molding involves melting plastic polymers at high temperatures to create sterile and contaminant-free medical equipment. By reshaping the plastics in aluminum or steel molds, manufacturers can produce precise and customized medical devices that meet the highest standards of hygiene.
Insert Molding
Similar to overmolding, the insert molding technique involves molding a secondary component over an existing part, or the insert. What sets insert molding apart is that it is a single process and can be used with various materials, such as plastics, metals, or alloys.
Overmolding
Overmolding is an advanced technique that involves molding one or two components over an existing structure, resulting in a strong and durable grip. This two-step process, also known as two-shot molding, may have a longer production cycle, but the benefits are well worth it. With overmolding, manufacturers can create ergonomic handles to improve the comfort of everyday devices, which adds value and functionality to a wide range of items.
Liquid Silicone Injection Molding
Liquid silicone injection molding involves heating silicone to a liquid state and then molding it into various shapes, making it a versatile solution for developing medical products. Silicone, a plastic polymer, is specifically designed to meet the needs of the medical industry. However, it’s important to note that silicone molds may not be as durable as aluminum or steel molds, making this technique more suitable for small quantities and initial prototyping stages.
