Encapsulating inserts

The combination of plastics with metals to produce hybrid parts leads to new solutions and product ideas that can be reliably implemented using our modular injection molding technology. Whether you wish to encapsulate your inserts with thermoplastics, thermosets or liquid silicone.


Our versatile machine concepts can always be individually configured to meet your requirements. A good example of this are turnkey reel-to-reel systems built around a vertical ALLROUNDER V for automated inline production. This enables you to encapsulate leadframes in short cycles, producing top-quality parts.


  • All injection moldable materials can be processed to produce hybrid parts
  • Variety: wide range of different machines and robotic technologies
  • Precisely tailored vertical ALLROUNDERs for manual to fully-automatic production
  • Turnkey reel-to-reel systems
  • Maximum process control through integration of all peripheral equipment into a central machine controller

Application examples

Rotary encoder
The complex electronic component is produced in a single process: a robotic system positions a sensor on the nozzle side of the mold and a magnetic disc on the ejector side. In order to combine the insert with the magnet, the sensor is encapsulated with a carrier plate.

Internal conductors
ARBURG has designed a production cell for the fully automatic volume production of internal conductors for Fakra connectors, encapsulating up to 72,000 pins per day. The associated robotic systems and peripherals are characterized by extremely fast and precise handling of the delicate inserts.

Leadframes can be encapsulated with plastic using the reel-to-reel process. For the production of clips, a vertical ALLROUNDER 275 V injection molding machine is equipped with a combination mold, which separates the finished parts from the carrier strip. The process impresses with short cycle times and high part quality.

Fuel tank strainer
A vertical ALLROUNDER 375 V shows how fuel tank strainers can be produced in small batch volumes cost-effectively and to high quality standards by integrating manual operations and using innovative working methods. A total of seven production steps take place within a total cycle time of 50 seconds.
