Injection Systems

Nozzles and hot runner systems  |  Hot Half  Control Systems

The new European benchmark in Injection Systems

Born to unite long experience of its founders in the different sectors of the plastic processing, the passion for creating new and better solutions, transparency in dealing with customs and consistency that must exist among all the factors to achieve optimal results.




iSystem – The screwed injection systems

IHR Solution screwed systems can be used for a wide range of applications, from standard systems to special systems, designed for your every need.

Our technology includes a wide range of tips, including the patented Topless T version, which ensures rapid color changes, excellent mechanical performance of the molded polymer and low operating pressures.

Among the other advantages of our systems, which allow a modern and reactive management of your production, there are the reduced energy consumption, the simplicity of installation, the reduced dimensions of the clogging units and the savings in maintenance costs.

The screwed single nozzles

IHR nozzles differ in 4 categories:
- Single standards
- Individual Eco-Line
- Individual mini-molds
- Multi-tip

Thanks to the different solutions, iHR Solution is able to satisfy every type of request, from the most economical solutions for the molding of amorphous polymers in common use to high performance technical polymers, guaranteeing an excellent finish at the injection point and eliminating possible losses of material.

We propose the Hot-Half systems as an advanced interface with the mold, with the possibility of integrating with a specific design, the multiple needs that emerge increasingly pressing from the world of plastic molding.

iHR Solution Hot Halves have already been wired, assembled and tested, maximizing system performances. In this way, the assembly time on the mold and subsequent maintenance are shortened.

Based on customer needs, iHR Solution designs the best Hot Half solution that can be adapted to any type of mold holder, eliminating any possible installation errors.

The temperature control units, the pneumatic and hydraulic control units for the management of systems with obturation injection

iHR Solution also provides the components related to the obturation systems for the sequential management of pin closure, with the use of pneumatic or hydraulic solenoid valves and pressure multipliers, to bring the correct operating pressure to the system.

The wide range of control units differs according to the production sector of the printed parts, thus allowing to carefully monitor the parameters of the application and the system used.

Fast colour change

Our hot runner systems stand out for several very clear strengths that are reflected in numerous operational process benefits.

One of de main ones is that colour changes can be car- ried out in half of the time compared to the traditional solutions available on the market. This made possible by technology developed and patented by iHR, such as the Topless Tip.

Low operating pressures

We have the optimized performance of our systems by managing to convey plastic material inside of mould cavity reducing pressure drops to a minimum towards the gate.

The front gate area uses an innovative and patented system that, thanks a low-pressure drop, keeps material stress to a minimum.

Thermal uniformity of the material

The shape of our channels, the geometry of our components, the position and the type of our heaters are aimed at reducing the stress of the material and at maintaining its thermal uniformity from the entrance to the hot runner until the point when it reaches the cavity.

Simplified installation and maintenance

We pay particular attention to productivity and efficiency.

Each of our hot runner injection systems is designed and built as a single piece that, as far as the components subject to wear are concerned, can by very easily maintained.

And it is this simplicity that keeps the global perfor- mance of the system constant over time.

Versatility and interchangeability

Our hot runners are characterised by a high level of technological flexibility, which means that they can easi- ly be adapted to operational requirements. The system can be rapidly upgraded to match any change in re- quirement.

For example, a customer might start of using the system in an open flow version, and subsequently switch to the more performing valve gate version.

Obviously, the system needs to be correctly prepared and set up beforehand, but the time frame and costs of the work are advantageous for the customer.

Energy saving

Careful attention is paid to the development and design of screwed nozzles.

Moreover, the geometries and masses are optimally sized and proportioned in order to minimize energy dissipation and provide greater thermal insulation.

These characteristics allow our systems to work on average , at 15 - 20% of the machines power.
