The new era of injection molding
With the DH-System, hotset focuses on surface quality optimization and cost-efficient process optimization in plastic injection molding. Produce high-quality, defect-free and aesthetically sophisticated design surfaces based on a heating speed of 60 K/s without longer cycle times. And save energy thanks to low heating power in the injection molding process.
High quality surfaces
DH-System: Spot on, the right temperature at the right time, exactly in the right place in the cavity. The result: no visible weld line notches, flow lines or dull halos. In addition, you realize low wall thicknesses, filigree geometries or microstructures in top quality.
Design surfaces without visible weld lines
With the DH-system, you can precisely control the temperature in the injection mold where the weld line would occur. The plastic flow is optimized at the problematic point. As a result, the plastic flows into each other and joins without any visually visible weld line notch. We customize the DH-System to your injection molding application and mold.
Very thin wall thicknesses
No matt points
Partial optimization of the molding
Functionally designed surfaces with fine microstructures require a high level of molding precision. This is conventionally achieved via high mold temperatures with longer cycle times – or via the DH-System with partial mold tempering and constant cycle times.
The shortest top quality cycles
The DH-System works in an extremely dynamic way. With a heating rate of 60 K/s (at the cavity surface), the injection molding tool is quickly heated up at the right point and above all, cooled down very quickly. Remove from the mold in the shortest possible time and manufacture top quality plastic designed surfaces in short cycles.
Partial, dynamic mold tempering
Same or shorter cycle times
If you want to achieve high-quality, defect-free plastic design surfaces without extended cycle times, turn to the DH-System. It combines quality and speed. We have also already managed to even shorten the cycle time.
Minimal energy demand
Save energy, reduce costs. The DH-system is highly energy-efficient due to dynamic mold temperature control in combination with thermal insulation in the mold. In practice, low heating powers averaging around 100 W are sufficient. The DH-System thus stands for efficiency and sustainability in plastic injection molding.
Minimized energy consumption
The DH-system brings the amount of heat into the mold that is actually needed. No unnecessary, excessive mold temperature control! You can get by with an average of around 100 W of heating power per hour. With optimized part quality and high-quality design surfaces.
Range of services
The basic concept of the new DH-system is that it is always designed by hotset engineering as an individually configured complete solution with control technology adapted to the specific application. It is composed of various hardware and software components and — similar to a hot runner system — is provided ready for integration into the mold.
A new thermal sensor with an extremely short response time gives the hotset DH-system for partial and cyclic cavity temperature control even greater process accuracy.
Thanks to its fast response behavior, the new cavity sensor detects even the smallest temperature changes and deviations in near real time. In a fraction of a second, the measured values are then forwarded to the DH-system controller and graphically processed.
Especially for plastics with a small thermal processing window or for 3D contours, the design of the DH-system by means of thermal simulation is essential. For this purpose, hotset uses specially adapted simulation software. This allows the effects of dynamic temperature control to be predicted very accurately. Already in the design phase, an insufficient temperature distribution is detected by the simulation. It can be compensated by constructive measures and adaptation of the DH-system.
