Automated, flexible, and efficient, this hybrid-AM strategy could become the default means for making injection mold tooling in the future. “There’s no question, in my mind, that it will be either Mantle’s technology or a similar technology that incorporates additive and subtractive processes,” says Sorom.

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

The years of development work have allowed Mantle’s process to achieve tolerances as tight as 0.001 in and smoothness of 2-3 microns Ra, meaning that the required finishing is relatively minor compared with what is needed for other methods. According to Mantle, the process has saved its customers up to 70% of production time when compared with more conventional subtractive machining.

While the melting process does not provide perfect mixing, this study shows that mixing is indeed initiated during melting.

A competing process, binder jetting, forms the desired shape by selectively depositing a layer of adhesive binder onto a bed of powdered metal. After each layer, the platform is lowered and an additional layer of powder is applied, followed by another layer of binder. When printing is complete, the part is transferred to a furnace for sintering, thus eliminating the need for a laser or electron beam. However, the part shrinks significantly during the densification process, as media and binding materials are vaporized. Controlling dimensions is complicated by changes that can be as large as 20% to 25%. Shrinkage can be especially problematic at transitions between thick and thin regions, where residual stress can be imparted to the tool and may even cause breakage.

Processors with sustainability goals or mandates have a number of ways to reach their goals. Biopolymers are among them.

The Plastics Industry Association (PLASTICS) has released final figures for NPE2024: The Plastics Show (May 6-10; Orlando) that officially make it the largest ever NPE in several key metrics.

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

While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

High Density Polyethylene (HDPE) Market Analysis: Plant Capacity, Production, Process, Technology, Operating Efficiency, Demand & Supply, End-Use, Grade, Foreign Trade, Sales Channel, Regional Demand, Company Share, Manufacturing Process, 2015-2035

Additive technology creates air pockets in film during orientation, cutting down on the amount of resin needed while boosting opacity, mechanical properties and recyclability.

Most of the workflow is hands-off. The printer builds the part up gradually, laying down paste layer by layer, drying it, and periodically removing material with an integrated CNC machine.  Placing this step before sintering boosts efficiency by enabling the system to cut this material away while it is still soft. The machine can run for hours or days without operator intervention, guided by software and the digital model of the geometry.

Meanwhile, the Asian HDPE market generally maintained stability, with the notable exception of China, which experienced a decline amid a bearish sentiment driven by falling international crude oil prices. This decline in oil prices, largely due to reduced Chinese demand, exerted downward pressure on HDPE costs, aligning with the return of some polyethylene (PE) maintenance units that are anticipated to increase supply. Despite this, the market remains deeply concerned about future demand prospects, even as crude oil prices continue to fall steadily, with geopolitical tensions in the Middle East showing no signs of escalation. In China, although HDPE supplies have resumed with the restart of production facilities, the overall market sentiment remains subdued. Traders are suggesting discounts to stimulate trade, but these measures are not yet seen as sufficient to boost demand significantly. Additionally, the impact of Typhoon Gaemi on the Fujian province in southern China has introduced further uncertainty, as heavy rains and strong downpours threaten to disrupt the supply chain, exacerbating existing challenges in the market including HDPE.

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 additive manufacturing (AM) approach in widest use is powder bed fusion, in which an energy source, either a laser or electron beam, forms the geometry by selectively heating a layer of metal powder to its melting temperature. Layer by layer, the tool is built by fusing the powder only where necessary. Powder bed fusion has found a niche in complex applications in the aerospace, healthcare, and automotive sectors, where gains in efficiency and quality justify the expense and complexity of the laser or electron beam system.

Mantle’s strategy to counter the effects of densification has been twofold: prevention and prediction. The process is designed to reduce the dimensional effects of densification, from 20-25% to less than 9%.

The global High-Density Polyethylene (HDPE) market exhibited divergent trends, with prices in the USA experiencing a decline while in Asia, the HDPE market remained consistent, except for China, which faced a bearish trend. A significant factor contributing to the easing of prices was the declining cost of crude oil, which had a broad impact on the global market. Despite these price adjustments, demand from key downstream sectors such as construction, packaging, and automotive remained moderately low by the end of the month. Supply constraints and seasonal factors further influenced regional market dynamics. Consequently, the price of HDPE Injection Molding grade FOB Texas in the USA dropped by 2%, and Chinese HDPE Injection Molding EXW Jiangsu also decreased by 2%, while other Asian countries and Europe maintained price consistency during the week ending on July 26, 2024. The HDPE market in the USA experienced depreciation, continuing the trend from the previous week as trading activities eased towards the end of the month. Export business softened due to competitive offers from China, prompting North American producers to consider agile export pricing strategies to remain competitive in incremental sales to avoid excessive inventory buildup. Major energy markets also saw a downturn, with Crude Oil recording its third consecutive weekly decline amid ongoing demand concerns from China. Despite an increase in feedstock Ethylene prices, HDPE prices remained low due to sufficient supply and diminished demand.  Further, the potential for a series of storms or even a single significant storm could disrupt petrochemical and plastics production, creating supply challenges that might impact HDPE prices in the near term within the region.  Meanwhile, the Asian HDPE market generally maintained stability, with the notable exception of China, which experienced a decline amid a bearish sentiment driven by falling international crude oil prices.

According to ChemAnalyst, HDPE prices in the Asian market may be affected by ongoing discussions for August shipment cargoes while buyers are exercising caution as they seek greater clarity regarding settlement prices in the coming weeks. In the US market, moderate demand is anticipated, with prices potentially influenced by freight rates amid peak season demand.  Additionally, the interplay between global supply chain conditions and regional economic factors will likely play a critical role in shaping HDPE market trends in the near term.

Sustainability continues to dominate new additives technology, but upping performance is also evident. Most of the new additives have been targeted to commodity resins and particularly polyolefins.

Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.

Additive techniques for making molds and inserts require post-processing to remove witness lines and give the tool its final shape and finish necessary for molding plastic. Hybrid systems reduce this work by incorporating subtractive machining steps into the build process. By reducing the amount of post-processing work, this approach frees skilled tool makers to work on a greater number of projects by reducing the time spent per tool. This could be especially important given reported shortages of workers with highly specialized skills.

Development of additive toolmaking processes (aka 3D printing) have opened new possibilities for geometries that cannot be achieved with traditional machining of steel blanks. These geometries include tools with conformal cooling channels, which can make injection molding operations more efficient and prevent defects due to uneven cooling. Approaches differ both in their method of forming the shape of the tooling and the method of solidifying the material.

Introduced by Zeiger and Spark Industries at the PTXPO, the nozzle is designed for maximum heat transfer and uniformity with a continuous taper for self cleaning.

In February, Mantle released case studies describing additional success stories from injection molding customers. Westec Plastics Corporation used Mantle technology to produce a prototype tool for validating a medical diagnostic part. Grinding and EDM work to finish the 3D printed inserts required only 10 hr, compared with 35 to 40 hr for traditional techniques.

The resulting tool is suitable for production and performance is comparable to a traditionally made steel tool from the same material. In the case of H13, the material is the same chemically. The lifespan of printed tools in production is estimated to be within 10% of that for traditionally built tools. Mantle-printed tool inserts in use at injection molder Tessy Plastics, have reportedly run 1.65 million cycles and counting.

According to ChemAnalyst, HDPE prices in the Asian market may be affected by ongoing discussions for August shipment cargoes while buyers are exercising caution as they seek greater clarity regarding settlement prices in the coming weeks.
