Energy BLOCKER®
3D printed Energy BLOCKERs® made of hardened steel reduce the energy consumption of your hot runner manifold up to 52% compared to commercially available pressure pieces made of titanium, depending on the application.
ENERGY EFFICIENCY
Highest energy efficiency is the demand on the Energy BLOCKER®, due to your patent-pending geometry, you reduce the Heat dissipation of the distribution system by 30 to 52%
STIFFNESS
The Energy BLOCKERs® are made of hardened steel and are therefore significantly more pressure-resistant than conventional titanium pressure pieces. The contact surface towards your tool remains unchanged in size and thus the tool stiffness is increased.
GRANDABILITY
Titanium for grinding is difficult on the process side and therefore a disadvantage with the usual printed pieces on the market. Energy BLOCKER® made of hardened steel are easy to grind if necessary, in principle the components are already delivered ground to target dimensions.
ISOLATION
The thermal insulation of the Energy BLOCKER® against your tool not only saves energy costs when operating the hot runner system, but also reduces the necessary cooling capacity for your mold. This saves additional energy.
ADDITIVE MANUFACTURED
The special geometry of the Energy BLOCKER® with its ribs of variable wall thickness can only be produced by means of 3D printing. The entire component is therefore additively manufactured and then ground to the finished height for you.
HEXAGONSTRUCTURE
The hexagon structure gives the Energy BLOCKERS® their high stiffness with low material consumption and thus perfect insulation. As with MONOLITH® nozzles, this structure is decisive for performance.
Continuous development and the passion to innovate is our incentive.

Additively manufactured Energy BLOCKER® for hot runner systems
The project was funded by the European Union to develop energy-saving pressure pieces for hot runner manifolds. Titanium is commonly used on the market as a material for pressure pieces. However, due to the low compressive strength of titanium, large contact surfaces and cross-sections are required, resulting in high energy consumption despite low thermal conductivity values.
The project therefore developed the now patented and additively manufactured pressure pieces under the name Energy BLOCKER®.
Thanks to a new design using a hexagonal structure, it was possible to dispense with titanium. Energy BLOCKER® cannot be machined due to the complicated hexagonal channels. They can only be manufactured using 3D printing.
The corresponding 3D printing technology, including peripheral equipment for powder handling and post-processing, was purchased and put into operation.
The project was funded by the PIUS-Invest programme (co-financed by the European Union).
Amortization
Energy BLOCKER® pays for itself in a very short time due to the excellent insulation and associated energy savings.
With an 8-fold hot runner system as shown, the saving is in operation compared to commercially available titanium thrust pieces ~600 watts.
This means you save 90% of the time you use your injection mold Calendar year 4730kWh. This corresponds to the consumption of an average average 4-person household.
The Energy BLOCKER® brings you clearly to the goal of climate neutrality closer, since in the example shown 700kg of CO² are saved per year.
Energy BLOCKER®, our product for a successful energy transition!
