SpeedStar Compact electric jetting head
The fastest electric jetting head for intermittent hot melt adhesive application. Adhesive savings of up to 50 %. Ideal for the packaging industry.
SpeedStar Compact is a top-class electric jetting head for the dot application of hot melt adhesive with the option of intermittent application. It is characterised by extreme precision and a high switching speed. Thanks to a frequency of up to 800 Hz, it can precisely apply even very small quantities of adhesive – ideal for applications with high speed and demands on cleanliness and savings.
The intermittent application technology makes it possible to reduce adhesive consumption by up to 50 %, without compromising on joint strength. SpeedStar thus delivers not only high-quality performance but also significant cost savings.

Applications for the SpeedStar Compact
SpeedStar Compact is the ideal jetting head for intermittent dot application, which is increasingly preferred in the packaging industry today thanks to significant adhesive savings. It is suitable for closing boxes, attaching labels, attaching product inserts or spot gluing in assembly processes.
The combination of extreme speed, precision and operational reliability makes this head an ideal solution for modern and efficient production lines.
The SpeedStar Compact jetting head is fully compatible with Robatech melters, hoses and control modules. Kaletech will supply you with a complete system, designed to match your requirements – including installation, training and service.
Precise gluing at high production speeds
Reliable gluing of small products is demanding. A single dot of adhesive must be placed precisely. Short beads with the exact length must be applied to the correct spot.
SpeedStar Compact achieves this high precision of the hot melt adhesive application through its fast opening and closing speed. The electric jetting head can precisely position tiny dots and short beads even at very high production speeds thanks to its switching frequency of up to 800 Hz.
Consistent precision over the entire service life (500 million cycles)
Two conditions must be met to repeatably apply small dots and beads of adhesive precisely at high production speeds: consistent adhesive temperature and consistent viscosity.
However, even a few seconds of production stoppage or refilling with new hot melt adhesive causes fluctuations: the precision of the adhesive application decreases temporarily. Beads can be too short, dots too small. This can cause production rejects.
SpeedStar Compact does not have this problem. Automatic displacement control makes the adhesive application independent of changing operating conditions such as adhesive temperature, viscosity and mechanical wear. The application quality remains consistently precise – automatically and over the entire service life of the application head.
Automatic displacement control – a gain in time and quality
The intelligent control electronics of SpeedStar Compact enable automatic displacement control. They regulate the precise adhesive application and compensate for fluctuations that could otherwise lead to production stoppages or rejects.
If the precision of the adhesive application decreases and the number of production rejects increases, you usually have two options to increase the application quality again: readjust the stroke manually or replace the application head before the end of its service life. Both solutions are time-consuming and expensive. With SpeedStar Compact, the precision of adhesive application remains consistent over the entire service life.
The stroke of the SpeedStar Compact is factory-calibrated. Therefore, an application head can be replaced quickly with a new one – without manual readjustment and lengthy start-up procedures. Automatic displacement control takes care of any fine-tuning independently.
If several application heads are arranged next to each other, the stroke of each individual head must normally be adjusted manually due to mutual heating, to ensure precise adhesive application. With SpeedStar Compact, this is handled by automatic displacement control.
Fast defect detection: the intelligent control electronics monitor the stroke electronically. If glue pressure is present, the control detects whether or not adhesive has been applied.
Straightforward system integration via a 24-VDC connection
SpeedStar Compact features a detached electronics module with a 24-VDC standard interface. Complete system suppliers can use this interface to actuate the application head directly via PLC. The connection is quick and straightforward via direct wiring, without additional devices such as a booster.
The slim design also simplifies the mechanical installation of the application head in a system.
Save up to 50 % adhesive with hot-melt stitching
Thanks to its fast closing times and 500 million operating cycles, the SpeedStar Compact can be used for hot-melt stitching – intermittent dot application that replaces bead application. Compared to bead application, stitching can save up to 50 % of adhesive.
Safe, sustainable and reliable in operation
The SpeedStar Compact heating block and jetting element are covered with CoolTouch insulation. It reduces heat radiation, protects heat-sensitive products, such as chocolate, from heat during the adhesive application, protects operators from burns in the event of unintentional contact, and reduces energy consumption.
At 62 dB(A), SpeedStar Compact is one of the quiet application heads. Thanks to its protection class IP55, it can be washed down with water jets and is suitable for use in the food, beverage and pharmaceutical industries. The heating block's integrated filter keeps the application nozzle free from adhesive contamination and ensures problem-free adhesive discharge.
Feedback from the field
"With SpeedStar Compact, we were able to replace bead application with small dots. We were able to increase the production speed of our KKM 1 tray former by 20 % and save 50 % adhesive in the hot melt adhesive application," says Erhan Çubuk, General Manager, DMS Osman Çubuk Makine Ltd.
