Multi-Cavity Molds: Hot Runner Technology for Optimal Part-to-Part Consistency 

At this year's Moulding Expo in Stuttgart, Germany, Italian hot runner specialist HRSflow, San Polo di Piave, presented a new family of hot runner solutions for multi-cavity molds. The multicavity series is suitable for the large-scale production of injection molded products wherever short cycle times and high surface quality are specified, for example in medical applications, cosmetic articles, caps and closures, and packaging.

Reinforced Hot Runner Nozzle Range 

The fully assembled and wired hot runner systems H4016 complete the range of ready-to-install systems and hot halves from Hasco Hasenclever GmbH + Co KG, Lüdenscheid, Germany. They constitute an attractive solution, specially tailored to the market, with all the system components screwed together already.

New Hot Runner Systems Complete the Program 

In cooperation with two new subsidiaries, the Haidlmair Group, Nussbach, Austria, is showing several innovations in the field of hot-runner technology, mold monitoring and lifetime management. FDU Hotrunner GmbH, Frankenthal, Germany, markets the FDU (flat die unit) launched by Haidlmair in 2016, which, according to the manufacturer, is particularly characterized by the fact that, in comparison to circular nozzles, it introduces less shear-induced heat into the melt, shortens the cycle time and reduces the required injection pressure and energy consumption.

For the further development of the Streamrunner and also for customer demonstration purposes, Hasco hot runner has developed an innovative 32 cavity injection mold tool.

New Design Possibilities in Moldmaking

Products intended for use in building services must meet very high quality requirements in terms of both their constituent materials and functionality. A single-cavity mold for a floor grate made by Barku, which appears to be a simple part at first glance, called for a certain level of technical sophistication. This was provided by a moldmaker with the necessary technical understanding and hot-runner manufacturer Witosa who, between them, devised the right solution for what proved nevertheless to be a complex mold.

Nowhere are the demands imposed on materials higher than in the area of medical technology. That is understandable because, after all, what is ultimately at stake here is the patient’s health. But any materials manufacturers seeking to use hot runner technology to process polymers in compliance with strict directives and differentiated legal regulations also need the expertise possessed by the hot runner manufacturer’s application engineers.

Günther has recently installed two new injection-molding machines for customer trials in its technical center.

It is a hot runner nozzle such as had never been seen before Fakuma 2021: with a honeycomb structure on the outside and, in the nozzle interior, integrated insulation gaps manufactured in one part by the additive SLM process, in which even the fastening nut is captively printed on the nozzle body. The pride of the concept is the special algorithmic modification of the nozzles for any application case.

A mold-making job with up to 30 nozzles is processed in the SLM machine in about 24 hours.

Additively Manufactured Hot Runner Manifolds with Needle Valve

With the Streamrunner from Hasco, the first additively manufactured hot runner, now completely new and space-saving options are also available for valve gate systems.

Multiple hot runner applications with very narrow nozzle pitch dimensions are, especially when using valve gate technology, a major challenge for designers.

A needle drive needs space, which means that the distribution of the melt in the manifold is usually associated with restrictions when using a valve gating system. This basically leads to a greater space requirement and consequently also to larger mold sizes and injection molding machines.

With the Streamrunner from Hasco hot runner, the first additively manufactured hot runner on the market, now completely new and space-saving options are also available for valve gate systems, according to the company. 

Since the market launch in 2019, several customer projects have been carried out, demonstrating the advantages of the system. With the addition of a subsequent version with needle valve technology, Hasco has gone one step further. At Fakuma 2021 the company’s hot runner division presented a fully balanced 20-cavity system with needle valve technology in which the outside dimensions of the hot runner are just 124 x 124  mm.

Thanks to the additive manufacturing technology, the flow channels can be optimally designed rheologically by completely avoiding sharp edges and areas with poor flow characteristics. This gentle passage of the melt results in considerably lower shear stress in the melt and consequently better quality of the injection-molded parts.

As absolutely no plugs are needed, this compact design of the hot runner enables in some cases a pitch of only 18 mm. The system is equipped with individually controlled, screw-in nozzles, which can also be used for engineering plastics. The stroke motion of the needle takes place via a circular plate package that is driven by four pneumatic cylinders.

As with all other hot runner systems from Hasco, the Streamrunner with needle valve technology is individually designed and adjusted exactly to the respective application.
