What to consider when designing Medical device injection molded parts?

One of the main aspects that must consider when developing the Medical device injection molded parts design is the alignment of expectations of all involved parties which results in a constant negotiation process that starts even before the project starts to be built.

The maximum simplification of the mold is the principle that guides all the work, as this measure reduces costs, generates gains in productivity, and can increase the mold’s useful life. Each project, however, is unique, so that there is no ready-made or definitive solution when it comes to mold design.

Focus on maximum simplification and cost

For example, a project developer with a focus on maximum simplification and cost reduction may not meet the customer’s expectations of what he expects from his part or product, so when essential for the product, simplification must be put into perspective.

Thus, good communication, including with the toolmaker, is an essential aspect that needs to consider to achieve good results in Medical device injection molded parts design in thermoplastic injection. Without active and clear communication, the chances that the result will not meet anyone’s expectations are high.

About the technical aspects, it is necessary to consider some factors during the elaboration of the project. Check it out below:

The 6 technical aspects that observe:

1- Wall thickness:

The mold design allows the injected plastic resin to flow fluidly between the thicker and thinner-wall areas, thus preventing deformations in the product.

2- Cavities and drawers:

The presence of cavities and cores makes thermoplastic injection in the mold difficult. Thus, these solutions must be limited in use, to achieve more effective Medical device injection molded parts.

3- Medical device injection molded parts Angles and curves:

Sharp angles make it more difficult for the plastic resin to pass through during molding. Curves with open angles should be prioritized, as they facilitate the fluidity of the resin inside the mold.

4- Level of Detail:

One of the reasons that thermoplastic injection is widely common in industry worldwide is its great versatility. With the correct mold design, great levels of detail and precision are easy to achieve. It is necessary, however, that the level of detail does not make production unfeasible.

5- Material common in mold manufacturing:

Plastic injection molds also differ in the materials they manufacture from. This is because different types of resins adapt and work better with certain materials. So, you have to choose the mold material with utmost care.

6- Mold Ejection:

When designing Medical device injection molded parts, it is essential to consider the ejection process after the end of the molding. Ejection must be quick and occur in a way that does not present any risk of damage to the final product.

How to calculate the clamping force in plastic injection?

Do you have problems with mold closure in thermoplastic injection? So you need to find out the “clamping force”!

In thermoplastic injection, the clamping force refers to that necessary to keep the mold close during its filling. Knowing how to calculate this force correctly is essential for the success of the production process.

It is common, however, that operators do not pay attention to this detail. To avoid leaks, many bet on a force greater than necessary. This is a “security” measure that results in losses and increases costs.

Which cause wear and tear in the Medical device injection molded parts

The clamping force must be able to prevent the counterforce exerted by the injection process from opening the Medical device injection molded parts and causing the resin to leak, but it must also not be so extreme as to cause wear and tear in the mold and injection machines.

Our specialists in thermoplastic injection, operating in the market, show you how the clamping force calculates and its importance for the success of the thermoplastic injection process.

The importance of correctly calculating the clamping force

In the injection of thermoplastics, the resin in the form of granules is added to the injection machine, where it is heated and later, already molten, injected into a mold under high pressure. 

The mold common in the plastic injection is in two parts. This solution makes it possible to open the mold to extract the product after cooling the polymers. 

Without exerting a clamping force, the mold opens during the injection of polymers, causing the leakage of resins.

Deformations and dimensional of Medical device injection molded parts

Even the slightest error in the calculation of the clamping force can affect the Medical device injection molded parts, with deformations and dimensional changes, as well as lead to resin waste, through the formation of burrs.

But if when the clamping force is less than necessary the final product harm, when this force exceeds what is necessary, the losses even greater. 

Negative effects of working with a Medical device injection molded parts

Among the negative effects of working with a clamping force above the necessary, we can highlight:

• Premature wear on the mold;
• Deformation in cavities;
• Breaking puller pins;
• Breakage or cracking of toupees;
• Stretch the columns, facilitating breakage;
• Deformation of the plates, facilitating breakage.

How to correctly calculate the clamping force

Thus, as you can see, knowing how to correctly calculate the clamping force in the thermoplastic injection is essential for the success of the production process, conservation of the Medical device injection molded parts, and the injection machine.

Next, you will learn how to calculate it!

To calculate the mold clamping force correctly, you need to consider the following information:

• Projected area;
• Flow Ratio;
• Average pressure exerted by the injection material;
• Constant relative to material type.

How to find each of this information below, and then the clamping force formula. 

Projected area:

The projected area must consider all the parts projected on the movable Medical device injection molded parts plate (part, injection, and distribution channels). 

For those with multiple cavities, it suggests considering only one of them, since, in the clamping force formula, the number of existing cavities inform. 

Flow Ratio (LF/S):

Conclusion

Flow relationship, one must consider the flow path (LF), the distance between the gate and the point of the part farthest from the axis, and the average thickness of the part (S).

Liquid silicone Injection-molded Lawnmower parts:

Injection-molded Lawnmower parts with liquid silicone differ mainly by applying the cold polymer in a hot mold, that is, the opposite of other types. Also, once the material is molded, it cannot return to a liquid form.

Silicone is a material with excellent stability, resistance to temperature, and chemical variations, in addition to being an electrical and biocompatible insulator. Thus, this type of injection is widely common in the production of electrical connectors, medical equipment, and automotive components, among others.

Injection-molded Lawnmower parts Thin-wall molding:

This type of molding is common to manufacture thin-walled parts that need to be strong and durable. It is a process widely common in the production of parts for the most diverse purposes and segments.

In thin wall Injection-molded Lawnmower parts, quality control is a key step, with each part undergoing a careful inspection to identify possible defects, cracks, etc.

Ideal Injection-molded Lawnmower parts

In other words, there is a type of injection molding that meets your needs and is ideal for your product.

It is also worth mentioning that today the technology and development of thermoplastic and polymer injection allows you to create customized materials so that your products or parts have the characteristics you desire.

Benefits of Injection molded Lawnmower parts

So we can highlight the benefits of adopting injection molding in your production processes:

• Great versatility adapting to what you want;
• Possibility of producing on a large or small scale;
• Efficiency and productivity;
• Final product quality.

Remember that today there are a wide variety of resin options, each with specific characteristics. You will hardly find an Injection-molded Lawnmower parts company that works with all of them continuously.

Must have technical knowledge about Injection-molded Lawnmower parts

If you don’t have technical knowledge about polymers, you may not know which resin you want to use, but you certainly know what you want for your product. From there your potential partner’s experts can indicate the best material to achieve.

Knowledge of the sector you intend to serve:

It is very important that your thermoplastic component supplier knows the sectors to which your product, ensuring compliance with all requirements and regulations thereof.

You can request samples of products targeted at the same industry you plan to serve, and ask how long they’ve been working with that focus and what challenges and constraints they’ve faced since then.

Conclusion

The harsh reality is that possibly your first product design will not be perfect. Therefore, being able to count on prototypes allow us to identify flaws and weaknesses and thus improve the design.

Your new thermoplastic injection partner should be able to produce prototypes quickly to ensure agility in your product development.

What are injection molded handles and what are the benefits?

Today, the injection of plastics is present in the production processes of companies from the most diverse sectors, enabling the creation of high-quality solutions capable of meeting the needs of companies and producers.

Choose the best injection molded handles

In addition to taking every precaution to choose the best plastics manufacturing company, it is also important to know a little more about this production process. Knowledge and information are the tools to make better decisions.

Understand, from now on, what plastics injection is and discover the benefits that this technique can generate for your products or components!

What are injection molded handles? 

It is the application of two different polymers in the same mold to achieve specific objectives. This is changing the physical properties of the polymers or even reducing production costs.

Over the years, the thermoplastic injection has shown continuous development in injection-molded handles. Moreover, it delivers better results, whether in terms of productivity, quality, or the diversity of needs it can meet. 

Injection of plastics is a technique that meets these requirements. 

Types of the injection-molded handles

The plastics industry currently works with two types of injection:

• The machine base and the mold base
• Each of which has specific advantages and applications
• Choosing one of them is always related to the intended objective.

1 – Injection by machine requires two or more processing units. 

The molten plastic in each processing unit goes through a collector where it is combined. It applies to the mold by a single injection nozzle. The result is a product covered by a polymer film.

2 – On the other hand, mold injection

It is a hot chamber process. Here the two molten polymers are kept separate until the last production phase. 

The injection-molded handles bond when they reach the mold, which creates a double layer effect. This type of injection is very present in everyday products, such as toothbrushes, for example.

Why choose injection molded handles?

In addition to allowing you to achieve aesthetic effects, mold injection also allows you to achieve a variety of properties to meet the needs of the solution. 

It is essential for this, however, that those responsible for them know in depth the polymers and their behavior when joining together.

Now that you understand what plastic injection is, it’s time to understand the benefits of using this technique for your company.

The Benefits of Using Plastic Injection

In a business environment marked by high competitiveness, companies must always be looking for improvements. This allows them to stand out from the competition, whether with innovation, quality, or cost reduction.

Those who use plastic parts in their products, either as the main material or as a component, have the advantage of having a versatile industry. Injection molded handles have a wide variety of solutions, including injection.

In addition, it also guarantees that it will work with excellent raw materials and a wide range of applications.

Advantages of using a plastic injection in your production process

• Unique properties;
• Aesthetic improvements;
• Better cost-benefit ratio.

A practical example of the benefits of plastic injection

An example of how plastic injection can benefit your business is the use of recycled plastic inside the parts, while the surface maintains a fine finish with a virgin plastic house. 

Another example is that injection allows you to have plastic parts with greater thermal resistance, using polymers that are more resistant to this factor in the interior. 

Quality result of the injection-molded handles

Injection molding of thermoplastics is a productive process that stands out for its great versatility, productivity, and quality of the result, in addition to being an option without waste, allowing the reuse of leftovers and burrs.

It’s hard to think what the world would be like today without plastic. To see this, we just have to look around us. Polymers are present in almost everything we use in our daily lives, from food preservation to smartphones.

Variety of applications injection molded handles

The wide variety of Injection molded handles applications that plastic supports comes from its characteristics, its moldability. This allows the material to assume virtually any shape.

Come with us, we will tell you everything you need to know about thermoplastic injection and understand why it is a great advantage to have the process for manufacturing components for your products.

Injection molding: the production process of thermoplastics

The principle behind thermoplastic injection is simple: polymer particles are heated and then injected into molds, taking the desired shape after cooling. Thus, thermoplastics may be common to produce parts and products of all sizes and shapes. It all depends on the mold.

One of the advantages of this production process is the high productivity, allowing the manufacture of parts in a standardized way with maximum speed and minimum errors and waste, making it ideal for those who produce on large scales.

Reuse the material of injection-molded handles

But not only that! Injection molding is also one of the best options for those who need to manufacture prototypes. If the expecting result is not achieved, it is possible to reuse the material common in new modeling.

Conclusion

When it is necessary to mold parts with thick walls for structure and durability. This is always a measure with the risk of distortion and warping of the part during its cooling. This is because the part will not cool evenly in its thickness.
