The strict requirements of this process require a hygienic environment for production. This environment ensures that no ambient air, dust, or moisture settles on the mold or mixture while it sets. The rubber-like substance produced through this process is highly chemical resistant.

The way the medical plastic injection process is set up helps cut unnecessary injection molding costs — massive production deliveries and high-volume manufacturing help to maximize the process. Hence, whenever there is an extraordinary volume of medical injection parts being produced, the injection molding process can reduce the cost per part.

If you want to produce high-quality machined parts with a sleek appearance, it’s essential to consider some critical factors related to CNC machining.

The injection molding procedure offers the widest range of options for choosing materials. Although medical injection molding narrows the scope of injection molding materials, there are still many materials that are suitable for manufacturing medical-grade components. We’ll touch on that more in the later parts of this guide.

Plastics have a wide range of use in the medical field. They are almost indispensable in creating plastic injection molding medical parts and tools like Syringes, surgical gloves, IV tubes, catheters, etc. These products are for one-time use only, erasing the need for sterilization and reducing the spread of highly contagious or virulent diseases.

Equipment made in this manner has a high requirement for its material. While the walls are thin, the device or tool maintains its integrity and durability to an extent. As a result of these requirements, its base materials tend to be plastic (especially LCP or Polypropylene, or even nylon).

The process of plastic injection molding for medical devices is critical, with a high probability of failure. Thus, there are some factors one needs to consider before and during the design, planning, and operational procedure. They include:

There should be no breakable plastics in manufacturing devices to avoid or minimize biohazards in the medical field. Hence, each selected material should have a satisfactory durability index before being put to use.  More so, they should be able to exhibit a high level of tensile strength.

Medical-grade plastic materials are simply plastics designed to create medical products.  It is also suitable for manufacturing Vitro diagnostics and primary packaging products. These products help preserve and contain medicines to avoid contamination in pharmaceuticals.

Manufactures providing injection molding services use different plastic molding techniques to produce medical-grade parts. But here, we will be looking at the 4 common types, which include:

Silicone doesn’t react with biological tissue, making it even more suitable to implant it safely. However, this injection molding process requires many steps. This is also dependent on the properties expected of the resultant silicone product.

The ability to withstand adverse conditions is a crucial consideration for plastic molding materials. They must be reliable and durable when subjected to heat, corrosives, liquid, vibrations, and other human body movements. Most of the plastics used in this process come out tops in this requirement.

Medical injection molding is a cheaper and more efficient method of making medical and pharmaceutical parts, including medical devices, laboratory tools, equipment, and testing instruments. Medical parts made from this method reach a high level of precision, quality, and accuracy.

The application of plastic molding injection in the medical device industry is diverse. Medical suppliers go for this process as the products easily attain the stipulated standards of quality and safety. Besides, medical device plastic injection molding comes in handy in areas like:

As a result, the resin ends up looking misshapen, ugly, and weaker structurally than it should due to the sink marks. Gas-assisted injection molding is the solution to this problem of making plastic injection molding medical parts.

The extremely high level of precision needed within the aerospace industry makes CNC machining a suitable manufacturing process for the sector.

The process of medical injection molding edges out similar production procedures in the industry. With its smooth and seamless operation, there are numerous advantages the process offers, and they include but are not limited to:

The medical injection molding process uses a vast range of material options to manufacture medical and pharmaceutical parts. There are various plastic injection molding materials used that give the process high efficiency. Some of them are:

For medical component manufacturing, FDA requirements are the standards to aim at in all processes. The regulations for sterility and cleanliness are stringent and require strict observance. In all the stages of productions, ensure all inputs meet or surpass the laid down standards. For medical-grade approval, the factory must pass the standards in the components and production process.

The materials used in production are greatly dependent on the object being made. These molds (prototypes) go through extensive rounds of testing to ensure their usability.

The process involves running gas through the channels built into the mold.  The gas (Nitrogen gas) passes through the middle of these thicker sections. Also, this creates the pressure necessary to press the resin tightly against the mold, making a smooth, structurally sound part with zero sink marks.

A minimal need for medical products but is important. All housing equipment or facility, or device parts that come in contact with the human body must be contaminant-resistant. They should also go through sterilization processes without damage.

The use of metal in medical device manufacturing is a technique that we cannot overlook. The reason is that metal equipment plays a significant role when it needs equipment with high density, small size, and maneuverability. This doesn’t detract from the numerous uses and advantages of traditional 3D printing, medical plastic molding, or gas-assisted molding.

In plastic injection molding for the medical device industry, thin-wall molding is one of the most common processes. It is for producing tools or effects that involve both function and patient comfort. The walls of the injection parts of the medical device are much thinner relative to the complete pieces. The walls are usually thinner than 1mm.

Always consider the material’s area of use before selection. For instance, single-use materials like syringes, needles, tubing, and connectors should be transparent, flexible, and easy to sterilize. Likewise, surgical injection parts should be lightweight and ergonomic.

The gas-assisted injection molding method is not suitable for creating tools with sharp corners in their design, because gas pressure will reduce if it doesn’t flow in a straight line. However, this type is more suitable for producing complex parts.

The innovative medical injection molding process is a ground-breaking invention that has swept through the industry. The manufacturing of medical injection parts not only satisfies laid down industry standards but makes the usage process smooth. This article explained some of the rudiments of the process and other important details.

In the process of plastic injection for the medical device industry, exceptional accuracy is a must. Due to the tight tolerance margin, every inch, millimeter, or centimeter count can influence the whole molding development. Besides, it is essential to use skilled injection molding facilities to achieve this high-level accuracy.

Devices produced with this injection molding type include wearable devices, surgical tools, and catheter ablation tools.

A known fact about plastics used in injection molding is that it is ruggedly durable. These materials provide dogged strength and resistance to adverse environments and usage. Therefore, the products of this process can comfortably withstand heat, blunt force, and vibration without any incidence of cracks or breakages. Also, when they undergo sterilization in autoclaves, they don’t cave to the heat.

Some medical devices like tubes and respiratory masks are quite difficult to keep hygienic. So, liquid silicone injection molding is generally the most suitable in producing equipment like these.

Think of the best laboratory facility and medical devices, made with top quality finish, and it’s undoubtedly through the medical plastic molding process. One good thing about the procedure is that it is both cost-efficient and delivers with exceptional accuracy and consistency. Besides, it comes in handy when the volume of productions is high and requires a masterpiece level of construction.

This is a more complicated molding type. When carrying out regular molding, the thicker parts tend to dry or solidify slower than the thinner walls. The reason is that there isn’t enough pressure to pack the resin properly and make it even.

Generally, atomization technology creates a powder mix from the desired metals. This powder is made into a pellet (feedstock), which includes a binding agent that makes it easier to mold.

With the level of results of this process, it’s no surprise that it serves as the medical prototype development approval process for the FDA. Here, we explain what this medical injection molding process entails and its role in the medical industry.

After injection comes the removal of the binding agent through various means, including solvent, a catalytic process, thermal furnaces, or even a combination of these methods. This leaves behind injection parts with a 100% density at the end.

The materials utilized in this production process easily withstand the invasion of contaminates. Also, they don’t need much sterilization to stay germ-free. Because of this factor, the material easily meets the FDA standards and other stipulated requirements.

One way of producing durable and reliable medical-grade components that meet FDA standards is through medical injection molding. The process is now the go-to procedure for manufacturing state-of-the-art medical equipment because it offers countless advantages.
