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.

A Simple Cascade

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.

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.

Family molds belong to the state-of-the-art in injection molding – at least when wall thicknesses and volumes of individual components vary considerably. Using a trial mold soon ready for series production, Synventive demonstrates that – though demanding – optimal process control can be achieved using the right technology. The filling of each mold cavity is controlled individually and in real time. The Kunststoffe editorial team were among the first guests at the new Tech Center.

Husky introduces the UltraShot Injection System

According to the company, the UltraShot Injection System provides part design freedom, while improving part quality and speed of mold qualification.

Husky Injection Molding Systems, Ltd., Bolton, ON/Canada, presents its new injection system. As stated in a press release, the UltraShot Injection System’s injection control technology enables risk-free scalability with flawless part capability. Identical system behavior for each injection circuit provides process condition consistency with cavitation scaling. A predictable process from pilot to high cavitation – scalable to 128 cavities, enables producers to maximize cavitation without negative performance on balance or shot-to-shot variation.

The new injection system enables users to produce unconstrained, highly functional and validated parts, economically, where conventional injection molding processes cannot. This innovative cavity filling control and process optimization overcomes traditional constraints of pressure, L/T and difficult-to-mold resins. This enables part lightweighting for resin and process time savings and provides resin selection flexibility.

Compared to conventional hot runners, melt in the UltraShot Injection System experiences fewer high-pressure injection cycles, thus preserving the original resin properties. This leads to lower mold-in stress and better mechanical and optical properties in the molded part.

Powered by the Altanium Mold Controller, the new system reportedly provides highly advanced process monitoring and control for injection molding. The Altanium process control provides repeatability and traceability for part dimension consistency, good balance and a more stable process. Providing digital analysis creates a measurable discipline around the molding process and gives users full control and trend analysis of various processes resulting in improved, lower risk operations.
