Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.

The amount of part cooling achieved by Kool Gas depends on how the gas is handled throughout the cooling stage. Magalhaes says that if the gas is simply injected and held in place until the mold opens, cooling can be accelerated by 10% to 40%. On the other hand, if the gas is vented while the mold is still closed, cooling reportedly can be accelerated by up to 60%. However, the latter approach is harder to implement due to the need for more precise gas-nozzle positioning, venting while the mold is closed, and special controls to monitor internal mold pressure during the procedure.

WMT markets a new approach whereby the gas is cryogenically cooled to from -4 to -292 F. The normal gas stream is passed through a chamber where it is cooled by liquid nitrogen. This “Kool Gas” method creates a cold leading edge of gas that results in a plug-flow effect in the mold as the gas cores out the molten polymer. The plug flow can lead to a greater reduction in residual wall thickness than is achieved with conventional gas assist. Kool Gas also prevents foaming and produces smoother interior channels, Magalhaes claims. That is an advantage in parts designed for fluid transfer.

The next generation of BlueHalo’s (Arlington, Va.) Intense Eye Unmanned Aerial System (UAS) aircraft features an injection molded chassis using HX5, a multi-scale reinforced polymer from Alpine Advanced Materials (Dallas). In this application, the HX5 material is replacing machined aerospace-grade aluminum, helping make the craft stronger and lighter with increased efficiency and payload capacity. HX5 was originally developed by Lockheed Martin for use in the F-35 fighter jet to provide a nanocomposite material that offered the strength of aluminum but at half the weight. While Alpine declines to reveal the base resin for HX5, it does say that the nanocomposite exceeds the performance of PEEK and Ultem (PEI) and is comparable to Torlon (PAI).

In this three-part collection, veteran molder and moldmaker Jim Fattori brings to bear his 40+ years of on-the-job experience and provides molders his “from the trenches” perspective on on the why, where and how of venting injection molds. Take the trial-and-error out of the molding venting process.

Pearson says the PEP process differs from a patented Melea process (marketed here by Gain Technologies, Sterling Heights, Mich.), which apparently does not use a valve and thereby relies on timing of gas injection to control the amount of melt overflow into the secondary cavity. With PEP, timing of the gas is not critical and does not control the amount of melt displaced. Pearson notes that PEP draws upon Japanese developments dating back to the 1970s but not patented. The Japanese technique was apparently based on injecting the gas after the valves were opened, whereas PEP introduces gas before opening the valves.

Magalhaes says if the plastic is not cooled sufficiently before demolding, the residual internal heat can cause surface recrystallization and loss of grain texture, as well as stress relaxation and distortion. In extreme cases, internal foaming can occur. Longer mold-cooling time or use of a secondary cooling fixture are possible solutions, but they add cost to the process.

Conventional gas-assist methods, such as the short-shot and overflow techniques, may be difficult to apply to a multi-cavity mold, especially if the cavity sizes are dissimilar, says Terry Pearson, chairman of Cinpres Gas Injection (CGI) Ltd. in the U.K. The reason is the difficulty in controlling the amount of melt delivered to each cavity. Gas channels or hollowed-out areas in the part may vary in cross-section and be difficult to control. It may also be difficult to obtain the desired surface quality due to the inability to pressurize the melt at an early stage of the molding process.

In terms of processing, an Alpine spokesperson told Plastics Technology that any molder with experience running high-temperature materials should easily be able to mold with HX5. From a temperature standpoint, mold temps are typically above 300°F, with barrel temperatures near 750°F. Alpine says that HX5 is, on average, about four times less viscous than a filled PEEK material, allowing molders to reduce cycle time and fill pressures, resulting in parts with less warpage out of the tool. Compared to some instances with carbon-filled PEEK, where sprues were required to be much larger, Alpine says HX5 allows for smaller sprues that still achieve completely filled parts.

Kool Gas reportedly can be used with any gas-injection equipment and does not infringe on any current gas patents. It requires a compact liquid-nitrogen heat exchanger to be installed in-line with the gas-injection system on the moving platen, downstream of the gas-pressure regulation module but as close as possible to the gas-injection nozzle. Gas from the standard delivery system travels to the cryogenic system, where its temperature is instantly reduced to a user-selected temperature, then the gas continues to the gas nozzle and into the cavity. Cooling does not change the gas pressure, says Magalhaes.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

Each mold cavity has a secondary overflow cavity and a connecting runner channel. A PEP shut-off valve is installed in the runner channel between the primary and secondary cavities. The PEP valve is closed at the beginning of the injection cycle. When a cavity is filled, the machine nozzle valve is closed and gas is injected into the mold through a separate port. The PEP valve opens at a user-selected time, allowing melt in the cavity to be expelled by the gas into the secondary well. The introduction of gas applies the initial packing pressure to achieve good surface quality. To prevent the gas from forcing melt back into the hot-runner system, Pearson recommends using a shut-off nozzle or hot-runner valve gates, or else just holding the screw forward.

Although gas-assist molding reduces part wall thickness, cooling remains the largest portion of the molding cycle. Nitrogen gas provides very little cooling effect while it is coring out the part, says Ruis Magalhaes, research fellow at the Advanced Technology Center of the Warwick Manufacturing Group in Coventry, England. Warwick Manufacturing Technology (WMT), another part of the Group, markets technologies developed at the University of Warwick.

Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.

To address these concerns, CGI developed its new Plastic Expulsion Process (PEP), which uses the pressure generated in the mold by the gas, as well as special shut-off valves, to accurately and repeatably control material displacement in each cavity. With this approach, plastic gate location becomes less critical, Pearson says. Also, there is no need for exact control of short-shot volumes, no hesitation marks, and better mold surface replication. A greater degree of core-out is also said to be possible, permitting reduced wall thickness and cooling times.

While the major correction in PP prices was finally underway, generally stable pricing was anticipated for the other four commodity resins.
