Injection molding
A precise and efficient manufacturing process for producing plastic packaging solutions with complex shapes in a repeatable way.
Injection molded packaging solutions
What is injection molding?
Injection molding is a manufacturing process used to produce plastic parts. It's known for its efficiency and ability to produce complex shapes with high precision in a repeatable way.
The injection molding process involves heating raw material, injecting it into a mold, cooling it, and ejecting the finished part.

Applications of injection molded packaging
When should you choose injection molding?
Choosing the right manufacturing process is crucial for ensuring efficiency, cost-effectiveness, and quality in plastic packaging solutions. Injection molding is a preferred choice for companies in any sector, in particular OEM’s and Tier’s in the LiB and automotive industries, that want packaging...
...that is reusable:
Injection molded packaging solutions can be reused throughout the life of the program, fitting well into any logistics flow.
...that is suitable for automation:
Injection molded plastic packaging can be manufactured with greater dimensional tolerance control than thermoforming. This is crucial for lasers, sensors, and grippers during automatic handling.
...in high volumes:
For businesses looking to produce medium to large quantities, injection molding is a cost-effective solution due to its ability to handle high-volume production efficiently.
...in complex shapes:
Injection molded plastic packaging can be designed in more complex shapes compared to thermoformed solutions, ensuring optimal protection tailored to specific product needs.
With advanced material properties:
Injection molding allows for a diverse selection of engineered resins, offering enhanced properties for specialized applications.
...that is modular:
Nefab’s library of abrasion resistant TPU inserts makes it easy to reuse trays and containers in new programs.
…that is made from recycled content:
Injection molded packaging can be made from up to 100% recycled content, including post-consumer recycled material.
…that is recyclable:
Nefab's thermoformed packaging is made from recyclable materials creating a closed loop.
Nefab's injection molding capabilities
1. Design and engineering
Based on customer requirements, our experienced engineers develop custom concepts. They design specifically for the injection molding manufacturing process with the whole packaging flow in mind.
2. Samples / Prototypes and Testing
Utilizing dedicated in-house 3D printers, Nefab can quickly and cost-effectively manufacture samples. In our certified ISTA labs, these samples undergo rigorous testing.
3. Molds
Nefab has its own in-house mold workshops across the world as well as a network of partners and to create tooling efficiently.
4. Manufacturing
We manufacture custom packaging solutions in-house with a large range of injection molding machines and, when necessary, leverage a network of partners.
The most common plastic raw materials used in injection molding are high density polyethylene (HDPE) and polypropylene (PP). Additives can be added to improve some properties like stiffness, impact resistance, UV protection, etc. Alternatively, for specific applications there are engineered resins such as:
- Electrostatic dissipative (ESD) additives for electronics
- Fire retardant (FR)
- PC/ABS for stiffness and dimensions accuracy
- TPU for scratch sensitive parts
- Additional engineered materials such as (PC/PBT, glass filled plastics, and more) for the most demanding applications
At Nefab, we follow standardized quality routines to ensure we consistently deliver high quality parts according to customer specifications.
The injection molding process
1. Plastification
Raw material (granules) and the color masterbatch are fed into the injection unit and heated.
2. Injection
The heated material is pushed into the cavity of the mold under high pressure.
3. Packing / cooling
Once the mold cavity is full the material is packed and cooled down.
4. De-molding / ejection
When the material is solidified, the mold opens, and ejector pins push the part away from the mold.
5. Logistics services
As part of complete packaging and logistics solutions, Nefab offers added logistics services. This includes assembly work such as adding labels, label holders, loose inserts, tracking devices etc. Pooling services cover all operations required to provide returnable packaging when and where it is needed, e.g. repairing and cleaning.
6. Recycling programs
Nefab offers take-back programs for used or discarded plastic packing, where possible. Once the packaging has fulfilled its lifecycle, we collect it for recycling, and reuse it as raw material to produce new plastic packaging.
