Quick Guide on Injection-molded Cellular Parts

December 24, 2021

What is the Injection molded Cellular parts?

The harsh reality is that possibly your first product design will not be perfect. Therefore, being able to count on Injection-molded Cellular parts 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.

Cleanliness, organization, and safety of the workplace:

It is very important to know the facilities of your potential partners to check aspects such as cleanliness, organization, and good occupational health and safety practices, fundamental aspects of any serious company.

If the visit is not authorized or if you find conditions that do not meet expectations, it may be better to look for another partner, even if the prices offered were attractive. After all, those who can’t even organize the workplace will hardly have an organization in customer service.

Qualification of the Injection molded Cellular parts:

The thermoplastic Injection-molded Cellular parts process requires skilled labor on different fronts. For example, you need a material engineer for resin development, designers for mold production, qualified machine operators, etc.

If the potential partner does not have qualified specialists or technicians or does not invest in the training and specialization of your team, the chances that you will have an amateur, outdated and problematic service are high.

Plastic Injection Quick Guide: 4 Top Questions Answered

Plastic injection molding is part of different products common in our daily lives in objects such as remote controls, appliances, children’s toys, among others! But have you ever wondered how the plastic injection molding process is carried out? We take your doubts out now!

Injection-molded Cellular parts are performed using a molten material, which is to be glass, metal, rubber, plastic, etc.

Injection-molded Cellular parts under pressure and then cooled

A mold is filled with this material under pressure and then cooled, causing plastic molding to take place.


In this article, we’ll talk about plastic injection molding, so the common material is plastic resin.

The first plastic injection moldings carry out in the early 1870s, producing billiard balls. Later, these technologically advanced and new products could develop.

This process involves different elements of our daily lives; Injection molded Cellular parts produce everything from cups and children’s toys to military and automotive products, among others. To know everything about this subject, follow our article!

1 – How do Injection-molded Cellular parts work?

 As stated earlier, this process uses a molten material to create the molds. In the case of plastic injection molding, a plastic resin is common, which is initially melted until it reaches a molten state.

The raw material is pulled into the machine through a funnel, using gravity to feed the material. Afterward, the material passes into a cylinder until it reaches the heater, where it turns to the melt state from the solid state.

Injection-molded Cellular parts inject by a nozzle under pressure

Soon after, the material is injected by a nozzle under pressure, which directs it to the Injection molded Cellular parts, which are subjected to high pressure, and from that, there is the cooling of the material to be hardened.

This process takes about a minute or less.

2 – What are the usage of the main plastic?

Thermoplastics are the main ones common in this process, as they melt easily at high temperatures and are easy to reheat more often.

In addition, they have properties that allow the use of chemical additives that change color and it is easy to color with glitter, for example. Discover the main common thermoplastics:

Nylon: It is one of the main resins in the manufacture of

  • Fabrics,
  • Food packaging,
  • Automotive parts.

Injection-molded Cellular parts Polypropylene (PP):

It is one of the main ones common all over the world, it has outstanding characteristics such as chemical resistance, flexibility, and insulation.

Acrylonitrile Butadiene Styrene (ABS): It is commonly used for applications that need a tough exterior and thermal stability.

HIPS (High Impact Polystyrene): Thermoplastic that has high impact resistance and stability, generally common for signs.

Polycarbonate Injection-molded Cellular parts:

It is an alternative that has strength and lower cost. It is naturally transparent, which allows its use in bulletproof glass and medical use, such as test tubes, beakers, and pipettes.

 3 – What problems can you face with Injection molded Cellular parts?

We know that in any process there are certain disadvantages to not choosing the ideal partner, who has a well-structured process. Let’s check them out below!

(1) The initial cost is easy to raise, which is why it is important to look for partners who can advise you on ways to reduce the costs of your molds.

(2) To have precision and quality in the result, you must find the best specialists, as it is essential for the final appearance to be as expected in prototyping.

(3) Injection mold can take longer lead times than other processes.

(4) Revisions may not be easy to carry out, since some details of the finished part are easy to modular. It is bringing about the impossibility of alterations. An overhaul may require the creation of a new mold, which can harm the project, bringing additional costs.

4 – What are the main advantages?

Now that you know some disadvantages of this process, learn about the main advantages of Injection molded Cellular parts:

(1) High quantity production with an excellent cost-benefit ratio. The implementation is a big investment, but the manufacture of parts carries out with greater optimization and quality. It is easy to rescale according to the needs of each client.

(2) Plastic injection molding produces a low amount of waste, which significantly contributes to the environment.

(3) It has the possibility of using thousands of different resins, which have strength, quality, and durability.

(4) Product consistency, if you need to produce the same part for a long time, Injection molded Cellular parts allows for consistent repeatability, as well as offering an automated and streamlined process.
