Moldmaking Metrics and Proxies

The latest GBI Moldmaking, which was 42.8 in September/October, is another indication of weaker-than-expected moldmaking activity. Other than the GBI there are moldmaking proxies that provide key information.

In the hierarchy of the North American Industry Classification System (NAICS), the six-digit national industry classification for industrial molds (NAICS 333511) falls under the four-digit industry group (NAICS 3335) for metalworking machinery. In the PLASTICS Quarterly forecast from the Plastics Industry Association, estimates for industrial molds are derived from the broader measurement of metalworking machinery (see Table 1).

Manufacturers’ new orders for and shipments of metalworking machinery have been decreasing. The result is a predictable rise in inventory. As shown in Figure 2, new orders for metalworking machinery peaked in October 2021, reaching $3,149 million, and since August 2022 have oscillated around $2,701 million monthly.

Shipments, on the other hand, peaked in November 2022 valued at $2.923 million and thereafter also downtrended to a monthly average of $2,738 million. Total inventories of metalworking machinery have continued to increase since bottoming at $5,814 million in December 2020. Since then, inventories have been on the rise.

As the end of the year approaches, businesses that began strategizing for 2025 midway through the year are hoping for sustained economic growth. Broad-based economic expansion is essential for manufacturing to regain momentum, which would, in turn, benefit other sectors like the plastics industry supply chain.

Price Stability Is Key

Economic growth anchored in stable prices is essential for the plastics industry. According to the 2024 Size and Impact Report on the plastics industry, material costs are a significant expense. In 2023, they accounted for 46.0% of the value of shipments in plastics conversion and 38.0% in molds for plastics manufacturing. While stable prices support economic health, price volatility challenges businesses, including manufacturing.

The Producer Price Index for industrial mold manufacturing, specifically for metal injection molds used in plastics, rose 1.4% year-over-year in May, down from a peak 3.7% increase in October 2022. Although price increases have moderated this year, potential shocks from rising energy and steel costs could add upward pressure.

“A sustained path toward stable prices, increased productivity and a skilled labor force is essential for realizing sustained growth across the plastics and manufacturing industries.”

Skilled Labor Crisis Continues

Broad-based economic growth also requires flexible markets, enabling businesses to adjust labor inputs in response to changing conditions. However, finding skilled labor in manufacturing has been an ongoing challenge for the U.S. economy, affecting competitiveness both domestically and internationally.

According to PLASTICS estimates, labor costs in moldmaking for plastics accounted for 28.1% of revenue in 2023. Since June, the average hourly wage in manufacturing has risen faster than headline inflation. The latest Bureau of Labor Statistics data indicates that wages increased by 5.0% in September, while inflation was 2.4%. For most Americans, employment is the primary source of income, supporting consumption. Real wage growth, when accompanied by productivity gains, fuels sustained economic growth.

Higher Capital Costs Impede Growth

The higher cost of capital has created headwinds for the U.S. plastics industry, as its primary market — the manufacturing sector — faces an interest-rate-driven slump. Higher interest rates push up the required rate of return on capital, which in turn raises risk aversion, potentially stalling new product introductions and projects requiring new tooling.

In 2023, capital expenditures (CapEx) in moldmaking for plastics fell to $238.1 million, a 34% drop from 2022, reflecting the strain of elevated interest rates. The Federal Reserve’s 50-basis-point rate cut in December may be followed by additional cuts in the coming year, potentially rebalancing CapEx across the economy. However, achieving the Fed's longer-term target rate of 2.9% will depend on where the economy stands in the business cycle.

New Strategies For U.S. Competitiveness

It is no secret that Asian economies have aggressively pursued industrial policies in pursuit of global competitiveness. While the U.S. has not done so in the previous years, think tanks are critiquing the recent American-style industrial policy, as reported by the Center for American Progress: “How Biden’s American-Style Industrial Policy Will Create Quality Jobs,” October 27, 2022. The Inflation Reduction Act, the CHIPS and Science Act and the Infrastructure Investment and Jobs Act, reflect the Biden Administration’s bid to boost economic growth.

Clean energy and climate change are at the core of the Inflation Reduction Act, with a goal of achieving a net-zero economy by 2050. This includes incentives for renewables and alternative sources of energy — wind, solar, hydroelectric, etc. Alternative sources of energy come with both challenges and opportunities. The CHIPS and Science Act is aimed at bringing the semiconductor industry back to the U.S. Its spillover effects are hoped to revitalize domestic manufacturing. Whether the CHIPS and Science Act will accomplish its goal remains to be seen — too soon to tell.

“U.S. plastics sector awaits post-election Fed policy while navigating growth challenges amid mixed economic conditions.”

Limitations of Increased Construction Spending

In August, the U.S. Census Bureau estimated the nominal value of construction spending in manufacturing at $238.3 billion, up from $201.5 billion in August of the previous year and nearly double the $129.7 billion recorded in August 2022. While analysts in financial markets may view this increase in construction spending as an indicator of rising manufacturing activity in the U.S. economy, such conclusions seem speculative. The Inflation Reduction Act provides for tax incentives encouraging the adoption of energy-efficient upgrades in new and existing buildings.

An increase in manufacturing structures does not necessarily equate to greater manufacturing output. A more reliable benchmark for assessing the impact of the CHIPS and Science Act is the share of manufacturing as a percentage of GDP, which can only be meaningfully evaluated over time.

Looking Ahead

The U.S. plastics industry remains an essential contributor to the broader manufacturing sector. This applies to all components of the plastics industry supply chain, such as moldmaking, reflecting both the opportunities and challenges within the current economic cycle. If there is one thing the business community is eagerly waiting for after the Presidential election, it is how the Federal Reserve navigates interest rate setting and the broader macroeconomic policy of the U.S., affecting materials costs, labor constraints and capital investment shortfalls that continue to impact growth.

Despite robust GDP projections in 2024, the economy faces uneven microeconomic conditions, particularly in housing and manufacturing. A sustained path toward stable prices, increased productivity and a skilled labor force is essential for realizing sustained growth across the plastics and manufacturing industries, supporting their roles as pillars of the U.S. economy.
