Medical Industry Application of Plastic Injection Molding

Plastic Injection Molding is a modern manufacturing process that offers a wide range of advantages when applied in the medical industry. A wide range of medical devices, components, laboratory equipment, and facilities are made by using the medical-grade plastic injection molding process. Its untold manufacturing advantages have made it a tailormade manufacturing process to meet certain requirements and specifications of the medical industry. This article is about the key benefits of applying plastic injection molding in the medical industry.

Key Benefits of Medical-Grade Plastic Injection Molding

The manufacturing of medical devices, parts, and laboratory equipment has paved the way for medical contractors to utilize efficient and economical methods to meet the specific needs of the medical industry. The applications of medical-grade plastic injection molding in the medical industry are as follows:

Implantable Medical Parts

● Beakers
● Test Tubes
● Containers
● Housing and Casing of Laboratory Equipment
● Surgical parts
● Surgical Equipment
● Drug Delivery Equipment

Orthopedics

Currently, the usage of plastic injection molding in the medical industry is limited and only applied to a small number of areas. However, it can be expanded and extended to almost all significant areas of the medical industry, especially where durable and sterilization-friendly medical parts are required. Plastic Injection Molding is undoubtedly the best manufacturing process for the bulk production of medical components.

Medical Equipment

Plastic Injection Molding is utilized in the production of a variety of medical equipment because it provides various production advantages, including:

Cost-Effectiveness

Plastic Injection Molding is the most economical method that serves as a blueprint for the bulk production of medical equipment.

Flawless Accuracy

The manufacturing and designing of medical devices, components, and equipment require high accuracy because of the low margin of error. The variation of even a single micron or millimeter can impact the normal process of production. Therefore, a manufacturing process with flawless accuracy is required for the production of medical equipment. Luckily, Plastic Injection Molding is that highly accurate method that can ensure the bulk production of medical equipment with a minimal part-to-part deviation.

Choice of Materials

Plastic Injection Molding is second to none when it comes to the choice of materials. There's a wide variety of plastic material options to choose from for the production of medical equipment. Of course, not all plastic materials are useful for manufacturing medical equipment, but there's still enough flexibility and versatility.

Durability

Most Plastic Materials show a high level of mechanical strength and durability. They are not only weather-resistant but also take minimal effect of environmental factors. Due to the high tensile strength, they can absorb a high amount of pressure without changing their shape or showing any breaking or cracking signs.

Low Susceptibility to contamination

Plastic materials are not very easily contaminable. They are so resistant to contamination that they don't show a change in composition even after multiple sterilizations.

Materials Characteristics

Plastic materials have all the required physical and chemical properties for the high-level production of medical equipment and devices.

High Sterilization Capacity

Plastic materials have a high sterilization capacity, thanks to which they're best to use for the production of medical devices and components.

Extreme Environment Resistant

The plastic materials utilized in the manufacturing processes for the medical industry are suitable for use in extreme environmental and climatic conditions. They can also be used in the production of medical devices that are going to be used as Bio-implants in the human body.

Choice of Materials for Medical-Grade Plastic Injection Molding

As we have described the applications of plastic injection molding in the medical industry in detail, it's to move on to the selection of the materials for the manufacturing of medical equipment and parts. Let us introduce you to some of the most popular plastic materials that are utilized in the medical industry.

Silicone –

The medical parts and devices that require a high level of flexibility and mechanical strength are commonly manufactured from silicone plastic materials. It's long-lasting, bio-implantable, and cost-effective for bulk production in the medical industry.

Polycarbonate –

When the visibility of the medical equipment and components is the priority, polycarbonate is a plastic material of choice because of its high mechanical strength with transparent nature. It's resistant to heat and UV light thus serves as the best plastic precursor for the production of laboratory equipment.

Polyethylene –

With a high molecular weight, polyethylene is the best choice to be used as a surface finish on wearable equipment and prosthetics. Medical components and devices made with polyethylene show high durability, great appearance, and sublime surface.

Polypropylene –

The medical parts, devices, and equipment that need multiple sterilizations are manufactured with polypropylene because of its high resistance to heat and radiation.
