What’s Medical Injection Molding?

Medical injection molding is a process in which various kinds of plastic material are used to manufacture medical equipment of different kinds. These tools serve numerous medical purposes and are made out of various forms of medical grade plastic materials.

The process of carrying out plastic injection molding consists of using an extensive process of medical injection molding.

The Advantages of Injection Molding in Medical Devices

Countless benefits may be attained by choosing injection molding techniques for manufacturing medical tools and equipment. A few of these important benefits have been discussed below.

Low scrap generation

We all know very well that plastics create a lot of scraps, landfills are dumped with a lot of plastic that is not recycled, and it causes harm to our environment. Choosing to opt for plastic injection molding will minimize that plastic scrap.

The plastic parts will be recycled and used to make other plastic products, and hence a positive addition will be featured to the environment as a whole.

Cost-Efficiency

The plastic injection molding process offers a lot of savings on the part of the cost. This is because there is no loss or wastage of the cost of raw materials. Moreover, using plastic injection molding machines also reduces using labor, and hence labor costs are cut down.

All these aspects allow the creation of medicinal tools at a very low cost which is always the best thing to go for and save on these products.

Exceptional accuracy

Material selection

There is a need for different medical tools, and each device has its requirement of plastic. So, when it comes to plastic injection molding, you can rest assured that you can get a lot of options to make your selection from versatile material choices.

Some materials need to be hard, some require flexibility, some should be resistant to scratches, and some must support lubricant use. a variation of the material may easily be sourced out of this process.

Durability

Durability is something so important that everyone looks forward to it in everything they invest into. The same goes for the parts of medical equipment and tools. Plastic injection molding delivers a long-lasting product.

The injection molding itself is so beneficial that it allows the plastic to gain more and more strength. This adds to the durability of the plastic when used for manufacturing different medical tools.

Contaminant resistance

Plastics used in the manufacture of medical devices are chosen after ensuring that they are based on the property of being contamination resistant. It is one of the crucial concerns for the medical equipment so that no negligence can be applied here.

The process of plastic injection molding itself ensures that proper focus is being laid on sterilization and contamination resistance of the materials.

Application of Plastic Injection Molding in the Medical Device Industry

The medical device industry needs medical-grade plastics to be used to manufacture required tools and laboratory equipment. Hence, when choosing the plastics to carry out the injection molding process, it is made sure that medical-grade plastic is only used.

This process of plastic injection molding is applied to numerous aspects of medicine. Ranging from manufacturing medical components, devices, and laboratory requirements, the process covers almost all areas to cater to the plastic needs of the medical field.

Material Selection for Medical Device Injection Molding

There could be ample material choices made to carry out the process of medical injection molding to create medical devices. A few of the most common medical-grade plastics commonly used comprise the following.

Polypropylene (PP):

Polypropylene is a very strength-oriented plastic choice used to manufacture several medical devices. The main reason for choosing this material is its ability to be highly resistant to heat and radioactivity.

The medical devices used in radioactive medical procedures or are subjected to constant sterilization in the autoclave may be made out of this plastic.

Polyethylene (PE):

Polythene is also one of the considered plastic injection molding materials used to manufacture medical devices that are required to be light in weight and smooth to touch and wear.

It won't be able to handle the process of sterilization through autoclave, but it is a very good and suitable choice to manufacture wearable medical devices.

Polystyrene (PS):

Petri dishes play a vital role in medicinal procedures, and these are mostly made out of polystyrene. Polystyrene is a kind of plastic that may not be suitable for sterilization through autoclaving but is used in numerous procedures which consist of surgical and lab products.

Catheter trays, trays used in lab research work, and tissue culture procedures are usually made out of this form of plastic, and hence it is subjected to plastic injection molding.

Polyetheretherketone (PEEK):

PEEK is a widely used form of plastic in several medical applications. Hip and spine implants consist of using PEEK due to their ability to be bone-friendly. It helps in repairing broken bones.

Silicone:

Silicon is a plastic injection molding material used in medical instances where a high level of flexibility is required. It may be used in drips, injections, and several other forms of medical devices and can be very cost-effective if produced in high volumes.

Medical Device Plastic Injection Molding Considerations

The process of plastic injection molding may require a lot of critical analysis beforehand, and there could be instances where the process may fail, and proper planning is required. These considerations are very important to be taken into account beforehand.

FDA Requirements

According to the FDA regulations, one of the most important things is to ensure that the level of cleanliness and sterilization is properly maintained. It is very important to ensure that the material used during the process is suitable for medical equipment and that the machine provides clean and sterilized parts.

Withstand Sterilization Processes

The plastics used in injection molding must have the capability to withstand the process of sterilization. It is very important to sterilize the plastics before being subjected to the injection process to meet medical standards.

Suitability to Extreme Environment

Medical grade plastic must have sufficient strength and resistance that it is capable of handling the extreme environment. Sometimes, it is radiation, sometimes heat, and when inserted into the human body, associated pressures are also laid down. So, the strength of plastic matters a lot.

Durability and Strength

Plastics that are brittle and easy to break won't have a place in medicine and hence must be avoided. They always create a risky situation. Therefore it is very important to pass such plastics through injection molding processes capable of being strong, flexible, and durable.

Common Forms of Injection Molding Techniques for Medical Devices Manufacture

There are commonly used types of injection molding techniques used to manufacture medical devices may comprise the following:

Thin wall molding

This process ensures a high level of comfort to the patient and is commonly used for manufacturing wearable medical devices like catheters and endoscopes. In this technique, the wall of the medical device is kept very thin, about less than 1mm.

Injection molding with gas

This kind of injection molding is carried out to ensure that no uneven surfaces and rough patches are left while modeling the medical devices. When the resin is passed through the molding process, the thicker areas take time to set compared to thinner ones.

In the gas application technique, the injection molding is subjected to the nitrogen gas that moves about all the cavities of the molding process, ensuring a smooth path is created for the medical device manufacturer.

3D printing

3D printing itself is not an injection molding process, but somehow it gives a base for creating medical devices. This process helps create a design before the actual medical device is passed through the molding process for creation.

This process gives a plastic base molding base for allowing a medical device to be created.

Liquid silicone molding

Silicon is one of the most commonly considered plastic materials in medicine; its flexible nature and ability to be sterilized and hygienically maintained make silicon popular.

Liquid silicon is used for injection molding, and medical devices like respiratory masks, cannula tubes, and many other medical devices are manufactured.

Conclusion

The plastic injection molding process in the medical field requires a lot of consideration. It is used to deal with medical procedures of different nature and hence needs to meet several regulatory requirements and ethical stances.

Hence, everything needs to be analyzed properly, ranging from the material process.

How Much Do You Really Know About Injection Molding?

Injection molding is a process in which similar products are made out of plastic in large volumes. These products are manufactured to cater to numerous industries, including the automobile industry, medicine, aviation, computing devices, electronic appliances, and many more.

What is Injection Molding?

The process in which molten plastic is subjected to molds left to settle is called injection molding. After some time, the final product is ready. In this process, numerous plastic components may be manufactured at a time and transported to required industries.

This process is one of the most eminent forms of production, which offers to produce plastic components used in various industries.

Types of Injection Molding

There are several kinds of injection molding, and each type has its considerations and production means; every single kind of injection molding is used to manufacture different components.

Thin wall molding

Thin wall molding is a kind of injection molding that is suitable for such plastic components that require thin sided walls.

In this type of injection molding, the process is so detailed and considerable that it ensures there lies no room for any cracks or quality issues with components.

Gas-assisted injection molding

Injection molding is a process that starts with using molten plastic that solidifies on cooling. In several cases, these plastic components may have some loopholes upon cooling. There might be specific spaces, cracks, and deformation present.

Gas-assisted injection molding passes gas through the molds filled with molten plastic. This helps eliminate any deformity on cooling and finishes the components' surface.

The gas, usually nitrogen gas, is considered in that aspect, and it passes through the hollow cavities of the molds that eliminate all the chances of damage.

Metal injection molding

The process of injection molding is limited to the extent of just plastic. Metal may also pass through this process. Several industries like the cellular industry may need such components made with metal rather than plastic.

Hence, here the role of metal injection molding is sufficiently essential and helps produce numerous parts commonly used. However, this industry is a very innovative one.

Liquid silicone injection molding

In the case of the usual injection molding process, the plastic is introduced through the injection molds, and it has a stiff and robust component that is not flexible in any way.

However, many such industrial requirements also exist where a component that may tolerate high temperature and is flexible is needed. In this case, liquid silicon is molded, and the desired output is achieved.

Reaction injection molding

The demand for foam plastic is also very significant worldwide in different industries, derived from the reaction injection molding process. In this procedure, the highly reactive forms of plastics are mixed. They polymerize and turn out to be in the foam state, which is then used.

Advantages and disadvantages of injection molding

A prevalent method of developing several plastic components is called injection molding. It is popular with metal components and has certain advantages and disadvantages that comprise the following.

Advantages:

Produces high volumes

One of the most important reasons for choosing injection molding is that it produces bulk components at once. This helps save time and costs and hence proves to be a very suitable approach for several businesses.

Most industries considering having components made out of injection molding usually need their parts manufactured in bulk. This bulk production helps them save costs, and they have stock at their end to cater to their production runs.

Handles complex layouts

No matter how complex the design of a component is, injection molding allows producing it with uniformity. The proper detailing and cuts are the same in every element as a finished product.

Several businesses have very complex needs for every part because of the nature of that component, and this aspect is very well catered to through injection molding.

Strength of components

The process of injection molding comprises a considerable level of strength. These components are solid that comes out as a result of injection molding. The main reason is that one single layer is considered for the process, and hence it ensures that there are no loopholes.

Due to its ability to produce strengthened parts, injection molding also allows other businesses to rely on it in the context of having accurate and quality-oriented details.

Controlled flexibility and rigidity

There is a different requirement for each component to be either flexible or rigid. The process of injection molding is versatile enough to cater to both forms. Hence, soft and flexible plastic parts are formed, and hard ones are also manufactured.

If you consider the example of the medical field, you will notice that the thickness and strength of test tubes, beakers, and other laboratory equipment are very rigid. However, considering the flexibility of oxygen masks and drips are very soft.

These two forms of components are used in one field, but this aspect is vital to consider to offer the right final products.

Less wastage

The wastage of plastic is a significant concern that harms the environment. However, injection molding is one such procedure where there is very little or no wastage of plastic.

The molten form is poured into molds, and hence nothing is lost during the process.

Businesses that are dependent on injection molding for their components may also be at peace that they won't end up buying such parts that damage the environment.

This procedure reduces plastic waste and does not emit any pollution.

Savings on labor cost

Injection molding is mainly carried out with high-tech machinery that is highly automated, and hence the need to employ much labor is reduced. Therefore this helps in saving labor costs.

When the labor costs are low for the injection molding manufacturers, the affordability for the end businesses will also be a suitable one that helps them draft realistic budgets for their final products.

Versatile material choice

Choosing to opt for injection molding has a massive advantage that there are so many materials choices available for the production of components. No matter what kind of product and what kind of hardness, flexibility, or thickness is needed, it caters to this aspect well.

Some industries require flexible and soft components, some products are such that they need complex and rigid structures, and some need the foamy touch. All these requirements are catered to through injection molding due to the availability of numerous material choices.

Disadvantages:

As much attention is given to the advantages, there should be an eye on the disadvantages of injection molding, which matters in several ways.

High initial investment

The costs involved in the initial setup of injection molding are very high. The tools and machinery amount to be costly, and hence the setup requires a lot of capital invested.

Not suitable for small batches

Injection molding is a process that is suitable only if you want to get massive volumes produced. It does make small batches as well but is not as cost-effective for them as it is for the larger volumes.

Design restrictions exist

One commonly faced problem with injection molding is that specific complex designs might not be created in terms of components. It may require a highly technical design team, and if you don't have it, you might struggle in the designing process.

Testing time is longer

After the machinery is set up, businesses carrying out injection molding need to spend a lot of time on the testing process. Unless the testing process is completed and correct parts are ready to be manufactured, the business may not start earning.

Common Materials Used for Injection Molding

The injection molding process may be carried out to produce several components and parts, and the most popular materials used for this process may include the following.

Acrylonitrile butadiene styrene

This material is used in injection molding and produces numerous components based on thermoplastics like keyboards, pipes, and automobile parts.

Nylon

Nylon is also one of the prevalent forms of materials used in injection molding, and through this, it produced fishnets, car tires, and insulators for electrical appliances.

High-density polythene

High-density polythene is considered a strength-oriented and hard form of plastic used in injection molding. Through the process, it produces bottles for different purposes and is used to make toys and plastic flower pots.

Low-density polythene

Low-density polythene is also used in food-grade materials. Cling wraps and food-grade crockery and cutlery based on disposable making are manufactured through injection molding using these materials.

Polycarbonate

Injection molding uses polycarbonate to manufacture plastic products that need to be hard and transparent at the same time. It is commonly used in making bullet proof glass, helmets, and particular hardware used in telecommunication.

Polypropylene

Polypropylene is a highly suitable material in the packing industry and is mainly used in packaging food and medicine. The chemicals of this material do not mix with the food and medicine packed, and hence it proves to be a very suitable choice in this case.

Polyoxymethylene

Polyoxymethylene is a material with a crystalline structure and is a harder one to choose. All such products that require a finish of crystalline structure followed by a hard structure are made using this choice.

Eyeglass frames, lock systems, bearings, and certain knife parts may be made using this material.

How does Injection Molding work?

The injection molding process is relatively straightforward. The injection molding machine is filled with the desirable plastic, which melts by heating. This melted plastic is then transferred to the desired molds through the machine's nozzle.

As soon as the liquid plastic in the molds is cooled down, it solidifies and is ready to use. However, the final product has to be molded out of the mold after taking solid form.

Applications of Injection Molding

Injection molding is used in various industries. Several things around us have been composed of several such components of plastic formed by passing through the process of injection molding. Some of its common applications are discussed below:

Automotive Components

What determines the accuracy of CNC machining parts

In CNC machining Parts programming, the correct use of methods and skills can effectively ensure and improve the accuracy of CNC machine processing. So, what determines the accuracy of CNC machining? Let's learn more about it!

CNC machine tool processing accuracy is determined by the position detection element, position detection element by the detection element (sensor), and signal processing device, which is an integral part of the CNC machine tool closed-loop servo system.

Its role is to detect the actual value of the table position and speed and the feedback signal back to the CNC device or servo device, thus forming a closed-loop control. The detection element is generally the use of light or magnetic principles to complete the position or speed detection.

According to the detection method, position detection elements are divided into direct measurement elements and indirect measurement elements. When measuring the linear motion of the machine tool, the linear detection element is generally used, called direct measurement, and the position closed-loop control is called complete closed-loop control. The measurement accuracy mainly depends on the accuracy of the measuring element and is not affected by the accuracy of the machine tool drive.

Since the linear displacement of the machine table is proportional to the rotation angle of the drive motor, it can measure the distance of the table movement indirectly by driving the rotation angle of the detection motor or screw. This method is called indirect measurement, and the position closed-loop control is called semi-closed-loop control.

The measurement accuracy of CNC machining depends on the accuracy of the detection element and the machine feed drive chain. The machining accuracy of the closed-loop CNC machine tool depends mainly on the accuracy of the position detection device. CNC machine tools have very stringent requirements for position detection elements, typically with 0.001-0.01 mm or less resolution.

The probability of damage to the detection element is higher than damage to the cable assembly. If the detection element fails, the first step is to check the wireless cable for broken wires, soiling, deformation, etc. The detection element can be judged by measuring its output. However, it is required to master the operating principle and the output signal of the detection element. For example: What to do when detecting equipment failure and mechanical oscillation (acceleration/deceleration)?

1) Pulse encoder failure. Then is the time to check if the voltage of the feedback line terminal on the speed unit drops to a certain point. If the voltage drops, the pulse encoder is defective and should replace the encoder.

2) The pulse encoder cross-coupling may be damaged, causing the shaft speed to be out of sync with the detected speed, and should replace the coupling.
