Medical Injection Molding – Everything You Must Know

Injection molding is a manufacturing process for creating parts by injecting molten material into a mold. It can be performed with various materials, including metals, glasses, elastomers, and thermoplastic and thermosetting polymers. 

Medical injection molding is a specialized form of this process used to create components for medical devices. Go4mould is a trustable name in the field of medical injection molding. We have a rich experience in this domain and have a team of experts who can cater to your needs in the best possible way.

This blog will give a brief overview of medical injection molding, including the benefits and importance of this process.

Medical injection molding: The basics

Manufacturing medical devices require precision and accuracy. Injection molding is a process that can provide these features while still being relatively quick and cost-effective. Medical plastic injection molding is a process that creates 3D parts by injecting molten material into a mould. The material is then cooled and ejected from the mold.

Significant benefits of medical device injection molding

Since its inception, injection molding has seen many improvements, and today it is one of the most commonly used manufacturing processes. There are several reasons for this, but some of the most significant benefits include:

  • Improved Ergonomics

Surgical plastic moulding can be used to create ergonomically designed medical devices. This is important as it can lead to improved patient outcomes. When devices are easy to use and comfortable, there is less chance of user error.

  • Improved Quality

Medical plastic injection molding can produce parts with very tight tolerances. This means there is less chance of human error during production. In addition, injection molding can create a very intricate surgical plastic mould.

  • Faster Production Times

One of the most significant benefits of medical device injection molding is the speed of the process. Injection molding is a speedy manufacturing process, which means that products can be brought to market quickly. With a quick turnaround time, medical device manufacturers can respond quickly to changes in the market.

In addition to the benefits above, medical injection molding is very versatile. It can be used to create various products, from simple syringes to complex implantable devices.

Why medical plastic injection moulding is the future

The medical industry is constantly evolving and changing. New technologies are being developed all the time, which means that the demand for new medical devices is always high. Since its inception, medical injection molding has been used to create various devices, from simple disposable syringes to more complex consumable implants. This technology offers several advantages over other manufacturing methods, and it will likely become even more popular in the future.

Applications of plastic injection molding in the medical industry

The medical industry has always been at the forefront of technology, and this is especially true when it comes to manufacturing. To meet the demands of the ever-changing medical landscape, manufacturers must always be on the lookout for new and better ways to produce their products. The applications of plastic injection molding in the medical industry vary.

Some of the most commonly used medical products that are created using plastic injection molding include:

  • Disposable syringes
  • Needles
  • IV Bags
  • Blood collection tubes
  • Catheters
  • Respirators
  • Hearing aids
  • Dental Inlays
  • Implants
  • Orthopedic devices
  • And many more

Consideration for choosing the right material for medical injection molding

One of the most critical aspects of medical plastic injection molding is choosing the suitable material for the job. The material must be biocompatible, which means that it will not cause any adverse reaction in the body. Other important aspects include:

  • Type of Mould

When choosing the suitable material for medical injection molding, the type of mould is essential. The mould must be designed in such a way that it can produce products that meet the highest standards of quality and safety. Multi-cavity moulds are often used to increase productivity and reduce costs.

  • Runner System

The runner system is another critical consideration. The material must flow easily through the runner system to avoid defects in the finished product. Full hot runner systems are often used to minimize the amount of material that is wasted. Semi-hot runner systems can also be used, but they tend to be more expensive.

  • FDA Requirements

Since the FDA regulates the medical industry, choosing a material that meets all of its requirements is essential. The material must be sterile and non-toxic. It should also be able to withstand the sterilization process without being damaged.

PEEK, PC, PS, ABS, PMMA, and PE are some of the most commonly used materials in medical injection molding. Mirror polishing, texturing, hot runner system, and gas-assisted injection molding are some of the unique processes we use to produce high-quality custom products with medical device injection moulding.
