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.

Pipette tips feature a challenging wall thickness/length ratio, an inner geometry that is key for analysis results, and a tip opening just a few tenths of a millimeter wide. They have been in extremely high demand during the coronavirus pandemic, which is why the mold construction and hot runner specialist Männer has developed a mold with an innovative cluster concept.

At the Männer test center in Bahlingen, Germany: an injection mold for manufacturing pipette tips, shown here in operation. Automation of the system is currently being set up

The new injection-molding machine Engel duo speed combines productivity and efficiency with short cycle times in a high clamping force range. The two-platen machine is thus making inroads into a range of packaging applications that were formerly the domain of toggle machines.

The area of application of cube molds has expanded to take in the production of technical parts. The new Allrounder Cube 1800 from Arburg with a clamping force of 1800 kN is providing the response to this trend. With its compact cube, this machine completes the portfolio of products at the lower end of the range.

At the heart of the cube machine is a compact cube designed by our partner Foboha which can be easily accessed from above. The rotation of the cube is powered servo-electrically and the horizontal movement relies on rack and pinion mechanisms

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.
