Solutions and applications for the plastics industry
Stäubli’s Plastics range of robots is the first line of 6 axis robots designed specifically for use in the plastics industry. They have been developed following detailed consultation and evaluation by both injection molding companies and system integrators.

|
Speed | Stäubli plastics robots are the fastest 6-axis robots on the market in terms of speed and acceleration (i.e. 0,8 second demold time inside a 4 second cycle) |
Cleanliness | Class 100 comes as standard |
Fulfilling the requirements of the plastics industry | Plastics robots are available ready to use with pre-wired Euromap (Europe) / SPI (USA) hardware and safety interlock, along with industry dedicated interface |
They are suitable for a very wide range of automation requirements in the plastics sector:
High speed demolding
- High speed demoulding
Their accuracy and inherent rigidity brings benefits in demolding speed.
The slim forearm minimizes mold opening time and the high positional accuracy means that the robot arm can be moved precisely to the demolding position. Stäubli has the fastest industrial robot available; interrupt intervals of just 0.59 seconds have been consistently achieved on specific demolding applications.
Secondary operations can also be readily included in the robots cycle.
Two-shot molding
- Two-shot moulding
6-axis robots can easily transfer and manipulate partly finished components between molds or IMMs for secondary molding and over-molding tasks.
In mold decoration & labeling
- In mould decoration & labeling
Labels for in mold decoration can be positioned accurately into the molds by the robot with a repeatability of ± 0.02 mm by using specifically designed double-sided gripping mechanisms on the robot arm. Molds featuring 4 or even 8 cavities can be filled, each with a different decorative label if required.
Insert loading
- Insert loading
Any shape, size and quantity of insert can readily be loaded into the mold by Plastics range robots. The full, 6-axis of movement, ensures precision placement and minimum mold opening time.
Controlled environment molding
- Controlled environment moulding
Plastics range robots, approved to Class 100, are suitable for operation in cleanrooms and low contamination environments in the medical, pharmaceutical, optical and electronics industries.
Product assembly
- Product assembly
Stäubli robots are ideally suited to perform a whole range of assembly tasks either alongside the IMM or downstream.
Glueing/sealing
- Glueing/sealing
The high dexterity of Plastics range robots can accommodate the most demanding glue laying and sealing tasks.
Testing
- Testing
Testing of the molded component is increasingly becoming a pre-requisite.
Stäubli robots can often perform the testing required within the cycle time of the IMM.
Packaging
- Packaging
The molded part can be trimmed, desprued, re-oriented, loaded and stacked directly into the output container by the robot, all sequences completed within the operating cycle of the IMM.
Plastic injection molders are increasingly adding value to their activities by incorporating additional operations into the basic demolding cycle.
Stäubli’s Plastics range of robots offers the ideal automation solution, providing high speed demolding combined with the flexibility and accuracy to perform many additional tasks.
