In recent months that does look to be stabilising a little bit, but we went through a period last year where we were getting price increases from suppliers every two weeks. And, and quite often they were they were sending materials in under order and those prices had gone up compared to the day we've placed the order, and they refuse to deliver unless you paid the additional price. So there have been some real headaches there.

PET prices in October were on the way up by 3¢/lb to 4¢/lb based on an upward blip in feedstock costs, but were expected to drop again on the order of 1-2¢/lb in November-December. This would follow a decline of about 23¢/lb between July and September, according to RTi’s Kallman.

Both PCW’s Barry and RTi’s Chesshier ventured that this relative stability might well be shaken up within the first quarter, due to the substantial new capacity being brought on stream by Shell and Baystar, the new 50/50 joint venture between Borealis and Total Energies. Combined production will represent a 10% increase in annual domestic capacity. Noting that early 2023 will remain a buyer’s market, Chesshier said that suppliers will face further challenges from lower global demand. As Barry put it, “The export packaging pipeline was viewed as a likely bottleneck for producer export sales in the coming months. Prices in Asia were softening as well-stocked Chinese producers lowered offers to stimulate demand and Southeast Asian markets followed the softer trend.”

Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

Major contributing factors to the improved PE market balance were that after several years of high production rates, PE suppliers throttled back plant utilization rates to the low 70s percentile, in addition to offering lower-priced exports and spot material to bring down their high inventories.

Which is great, because we like the more specialist plastic mouldings where a complicated tool is required. So while we’re seeing a trend again towards part sourcing the tool from China, we’re also seeing more interest in using British engineering to solve problems and improve quality.

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

NP: At WSM, we specialise in high-end materials and applications with more requirements than a straightforward plastic molding. So for example, our customers might need some additional additives for strength, particular colours, something a bit more complex. As a result of our capabilities in that area, we do quite a bit of work in the aerospace industry on things like seating and you know, and the peripherals around the aircraft: things like USBs, monitor surrounds, etcetera. Naturally the aerospace market is starting to pick back up again after COVID. During the pandemic, as you can imagine, the aerospace market was very downtrodden, and limited for us. Last year, it started to show signs of coming back, and this year it's starting to increase quite considerably. So demand for aerospace materials and applications is growing right now. That said, it's been hard work, keeping up with material price increases, and trying to manage the customer through the impact of that.

Exhibitors and presenters at the plastics show emphasized 3D printing as a complement and aid to more traditional production processes.

Polypropylene prices in October were on the way down by double-digits, as propylene monomer contracts were expected to settle 9¢/lb to 11¢/lb lower, along with an expected margin contraction of 4¢/lb to 5¢/lb, according to PCW’s Barry, Spartan Polymers’ Newell, and The Plastic Exchange’s Greenberg. The market was characterized as very well supplied, amid continued lackluster demand, despite suppliers throttling back plant operating rates to a low of 70%

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

Across the show, sustainability ruled in new materials technology, from polyolefins and engineering resins to biobased materials.

NP: That’s a good question. A lot of what we do, because the use more complex materials, they can sometimes be less recyclable than perhaps off-the-shelf, standard materials. But at the same time, those components don’t tend to be the things that end up in landfills and waste streams. They’re specialist plastics with an extremely long lifespan, destined to be used over many years. I have to say, in the most part, the majority of plastic is now recyclable. And for me, it feels like it's an education thing as much as anything else. Let's stop talking about how bad plastics are for the environment, because in actual fact, most plastics are highly recyclable and highly productive in the functions they’re used for.

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

After successfully introducing a combined conference for moldmakers and injection molders in 2022, Plastics Technology and MoldMaking Technology are once again joining forces for a tooling/molding two-for-one.

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.

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.

NP: Well we have a facility in China that makes tools and as you say, we have a UK facility that makes a lot of tooling. During the pandemic of course we saw more people trying to source British-made tools. So that was good news for us, because it meant our tool room was busy. But as we're coming out of the pandemic, more people are saying they want a hybrid approach. So they would like tools made in China, but production in the UK – and the maintenance of those tools dealt with here. So there is some drift, but we’re also retaining some of that business here in the UK. And at WSM, we are lucky that we have some extremely talented toolmakers, some of the best in the country, and they can make some really quite exquisite tooling.

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

Polyethylene prices for October appeared to hold even and were expected to be generally flat for the last two months of the year, according to David Barry, PCW’s associate director for PE, PP, and PS; Robin Chesshier, RTi’s v.p. of PE, PS, and nylon 6 markets; and The Plastic Exchange’s Michael Greenberg.  Reporting on one longtime market watcher’s projections, Barry noted, “Don’t expect any big price swings for several months.” Meanwhile, suppliers notified customers they were postponing their increases of 5-7¢/lb from October to November, though these sources saw this move as mainly an effort to halt any further decline.

We find that new start-up businesses are very keen on incorporating those things. Top of their list is always “let's use recycled and recyclable materials in the products were proposing to make in order to safeguard the future generations”. We're on board with that fully. And we're very, very keen to recommend those things wherever we can and work with businesses to try and help reduce those carbon footprints.

While an uptick in benzene contract prices of about 40¢/gal was expected in November, these sources predicted that PS suppliers might opt to give up some margin due to high volumes of imported PS. According to PCW’s Barry, one resin distributor described the price gap between imported and domestic resin as “unsustainably large.”

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.

Gifted with extraordinary technical know how and an authoritative yet plain English writing style, in this collection of articles Fattori offers his insights on a variety of molding-related topics that are bound to make your days on the production floor go a little bit better.

How the development of new catalysts—notably metallocenes—paved the way for the development of material grades never before possible.

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.

These are the views of purchasing consultants from Resin Technology, Inc. (RTi), senior analysts from Houston-based PetroChemWire (PCW), CEO Michael Greenberg of The Plastics Exchange, and Scott Newell, executive v.p. of polyolefins at distributor/compounder Spartan Polymers.

The latter reported that PVC prices are forecasted to be flat in January, followed by a 2¢/lb drop in February and flat again in March, for a total decrease of 32¢/lb over nine months.

DG: Let’s talk about Interplas now. What are you hoping to talk to customers about during the three days in Birmingham, and why is it important for UK moulders to exhibit?

Both sources noted that falling PVC export prices have continued the downward pressure on domestic prices, along with increasing supplier inventories. However, Kallman reported that suppliers have exported a substantial volume of PVC and that Formosa had planned a shutdown of its Louisiana plant through November, which would perhaps result in a more balanced market. He noted that with the exception of wire and cable—the “most resilient market sector”—PVC demand is off in nearly all categories.

RTi’s Chesshier ventured that PS tabs could remain flat this month but may rise if benzene prices move up again. Meanwhile, the implied styrene cost based on a 30/70 formula of spot ethylene/benzene fell by nearly 2¢/lb to 36.2¢/lb going into November. Implied styrene costs have been hovering in the mid-30s since late August, according to Barry.

Polystyrene prices in October looked to be heading down by 4¢/lb, bringing the total three-month drop in prices to 40-43¢/lb, and they could bottom out for the last two months of the year, according to both PCW’s Barry and RTi’s Chesshier. Both noted that demand was down but that suppliers had stayed on top of things by lowering production rates.

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.

Core Technology Molding turned to Mold-Masters E-Multi auxiliary injection unit to help it win a job and dramatically change its process.

DG: We’ve talked about supply chain challenges. Now we’re facing a new obstacle, with energy prices being what they are. Has it given you an opportunity to look at your processes in house? A lot moulders are making changes, whether that be through capital investment, or through process changes, or even behaviour changes in house. Have you been able to do anything like that?

Kallman characterized domestic demand as slower and the market as well supplied, with attractively priced exports continuing to arrive at a steady pace.

NP: It's a platform for all the plastic manufacturers, so you get to see what your competition are up to, and understand what trends they’re seeing. The primary thing, however, is an exercise in sourcing new business. We do want to become a more global company, which would give us a competitive edge in the UK, so we want to meet other global businesses. And we also want to meet aspiring start-ups who have secured funding for new products. We’re very keen to be there at the beginning of their journey and lend our support and technical knowledge in both plastics and toolings.

For the November-December timeframe, these sources noted signs that prices were bottoming out, with flat to slightly lower pricing expected. “I think we haves some visibility of a bottom forming with a little bit of further drop,” said Newell. Barry saw potential for further price reduction in the fourth quarter, noting that demand in the global PP market was down and China was becoming a regular exporter of PP, the latest competitor for U.S. suppliers.

And perhaps, this focus on plastics being terrible is more down to our need to just throw something away rather than think about what we can do with it afterwards. We're very conscious of as a business that we recommend recycled and recyclable materials wherever we can.

Contract prices fell a total of about 11¢/lb in the third quarter, with more dramatic price drops in the spot market. As October approached, spot prices began to stabilize. Going into November, Greenberg put it this way: “Spot PE price were holding firm for three weeks in a row. Even as PE spot levels have seemingly found a floor, buyers continue to enjoy good availability for most grades near these yearly lows.” He did note that some more niche grades, such as injection molding LDPE, EVA, POE and rotomolding resins had been in tighter supply, and have good underlying demand if better supplies surface.

PVC prices in October were expected to drop another 5¢/lb following a cumulative drop of 15¢/lb in the previous three months. Moreover, similar decreases were expected for the last two months of 2022, which would bring the total decline in the second half of this year to 30¢/lb, according to Mark Kallman, RTi’s v.p. of PVC and engineering resins and PCW senior editor Donna Todd.

DG: It sounds challenging, but you’ve weathered that particular storm, which is great. You have a toolroom too right? Tell me what you’re seeing coming through the doors there?

While suppliers have throttled back production, these sources say there is a lot of material to be had and that heavily discounted spot deals were on the table. There was also substantial new capacity coming on stream, with ExxonMobil starting up its new plant and Heartland Polymers readying its PDH and PP units. Greenberg confirmed that some PP suppliers were offering deeply discounted railcars for higher volume orders as they aimed for better positioning in first-quarter 2023. He reported that there was good ongoing demand for packaged truckloads from processors that had drawn down their stocks and now required more material, and from others waiting for late railcars to arrive.

A halt in the pricing plunge for PE, PP, and PS appeared to be shaping up going into November, owing primarily to suppliers reducing their swollen inventories by throttling back production rates and, in the case of PE, multiplying attractive offers for exports and the domestic spot market. Still, first-quarter 2023 looks to be a buyer’s market for all five major commodity resins.

DG: Finally, what about incorporating recycled materials? Is that something that you're seeing more demand for? And is it something that you can cater to?

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.
