Hot insertion of metal threaded bushes / inserts in plastic parts
HENKEL + ROTH's hot insertion/hot embedding of metal threaded bushes (inserts) in plastic parts is more adaptable than ever before and thus fulfills your process and component requirements with high efficiency.
The separation, heating and controlled countersinking of different types of bushes is available as a custom-fit
- interchangeable device in semi-automatic assembly cells
- fast and precise 5-sided machining in automatic assembly machines
- integrated tool on 6-axis robots for automated production line
5-axis hot insertion machine
- automatic machine for flexible hot insertion of threaded bushes in plastic parts (e.g. intake manifolds, cylinder head covers, cladding parts, housings, etc.)
- 5-sided machining of plastic parts with 5 servo axes requires fewer reclamping operations and increases productivity
- insertion of different bushes is possible (e.g. with different thread diameters)
- Database query of type-dependent process parameters
- Manual or fully automatic insertion and removal of workpieces by gantry robot or mobile robot
Process knowledge in hot insertion for your application
- Separation system with variable heating for each individual bushing using high-frequency technology
- Reheating during the insertion process for challenging material pairings
- Regulated insertion of the bushings with an accuracy of ± 0, 05 mm in relation to the circumferential bore edge on the plastic part
- insertion head with floating bearing of the bushings to compensate for position tolerances of the bore holes
- Improvement of accuracy and cycle time by optimizing the holding and by air-assisted cooling of the bushings after insertion
- insertion processes with cycle times of up to 4s with suitable material pairings and optimized bushing geometry
Wide range of automation options
Decisive rationalization advantages can also be achieved with the five-axis hot insetion machine from HENKEL + ROTH GmbH thanks to a wide range of additional automation options.
The clamping system works with self-identifying interchangeable plates for the different plastic parts. This means that the machine can be converted to a new workpiece type very quickly. Depending on which type of part the system has identified, the position data for the insertion head and the bushing handling are loaded from a database in which the type-specific process parameters are stored.
The conveyor system for the bushing can be refilled without stopping the automatic system. The workpieces can be inserted and removed either manually or fully automatically in conjunction with a stationary or mobile robot.
Another plus point is the convenient operation thanks to user-friendly menu navigation via touch screen.
The robust design of the system, which is built on a sturdy steel frame, safely absorbs static and dynamic loads. Thanks to its compact architecture with integrated control cabinet, the HENKEL+ROTH automatic assembly machine can be easily integrated into the process chain of any plastics processor who wants to benefit from the time and precision advantages of flexible bushing hot insertion in five processing dimensions in times of constantly increasing cost and deadline pressure.
