Why it matters now: The global mechanical equipment forgings market is entering a sustained growth cycle, with a new IndexBox forecast projecting a 5.2% compound annual growth rate (CAGR) through 2035. This expansion is not occurring in isolation — it mirrors the accelerating pace of industrial automation deployment worldwide, where PLC-based control systems form the operational backbone of modern factories. As manufacturers pour capital into smart production lines, the demand for high-integrity forged components — used in everything from robotic actuators to conveyor drive assemblies — rises in lockstep.
Published on July 23, 2026, the IndexBox report anchors its baseline scenario in three converging forces: steady global industrial production growth, surging automation capital expenditure, and relentless investment in semiconductor fabrication capacity. By 2035, the market is expected to reach an index value of 165 relative to the 2025 baseline, signaling a structural shift rather than a cyclical uptick.
Analyst Insight: The 5.2% CAGR represents a conservative baseline. Upside scenarios tied to accelerated Industry 4.0 adoption — particularly in Southeast Asia and India — could push the index beyond 175 by 2035. PLC-intensive sectors such as automotive assembly, packaging machinery, and material handling are expected to account for over 40% of incremental forging demand.
Why PLC-Driven Automation Is Reshaping Forgings Demand
The link between mechanical equipment forgings and PLC automation is structural and direct. Every automated production cell relies on precision-machined, forged structural parts — housings, brackets, shafts, and gear blanks — that must withstand continuous duty cycles. As factories retrofit legacy lines with PLC-controlled servo systems and IoT-enabled actuators, the specification requirements for forgings tighten, driving value growth even in mature volume segments.
Forgings are preferred over castings in high-stress automation applications because their grain structure delivers superior fatigue resistance. A robotic welding arm running 24/7 under PLC sequencing demands components that will not fail under repetitive loading — and that engineering reality translates into steady replacement and upgrade demand across the installed base of automated equipment.
The IndexBox analysis identifies automation capex as the fastest-growing demand driver within the forgings market. Manufacturing enterprises in developed economies are allocating between 15% and 25% of their annual capital budgets to automation retrofits, much of it centered on PLC hardware upgrades, HMI modernization, and SCADA integration — all of which require physical mounting, enclosure, and actuation components sourced from forging supply chains.
Semiconductor Manufacturing: A Dual Catalyst for the Forgings Sector
Semiconductor fabrication is forging-intensive in ways the broader market often overlooks. Wafer-handling robots, chemical-mechanical planarization (CMP) systems, and vacuum chamber assemblies all depend on high-purity forged components that can operate in chemically aggressive, thermally extreme environments. The global semiconductor capex cycle — now running at over $180 billion annually — is a distinct and growing addressable market for specialty forging suppliers.
Furthermore, semiconductor growth feeds the PLC ecosystem directly. Every new fab requires thousands of PLC nodes for process control, environmental monitoring, and material handling. This cascading demand pulls forgings through multiple tiers of the industrial supply chain — from the structural frames of CNC machines that produce PLC enclosures to the forged tooling used in connector and terminal block manufacturing.
Market Trend: The semiconductor-forgings nexus is geographically concentrated. Taiwan, South Korea, and the United States collectively represent over 60% of semiconductor-related forging demand. Supply chain diversification efforts — including new fab projects in Japan, Germany, and Arizona — will redistribute this demand across multiple forging hubs through 2035.

Demand Structure by End-Use Sector
The IndexBox analysis segments mechanical equipment forgings demand across five principal end-use verticals. Industrial machinery — the category most directly tied to PLC automation — commands the largest share, followed by automotive powertrain and chassis applications. Semiconductor equipment, though smaller in absolute volume, carries the highest value-per-ton metrics due to stringent material and tolerance requirements.
Construction and mining equipment, energy infrastructure, and aerospace round out the demand base, each contributing distinct cyclical patterns that collectively smooth the market's long-term growth trajectory.
Supply Chain & Trade Flow Dynamics
China remains the single largest producer and consumer of mechanical equipment forgings, accounting for approximately 38% of global output. India has emerged as the fastest-growing production hub, with forging capacity expanding at roughly 7% annually to serve both domestic automation demand and export markets. European forging specialists continue to dominate the high-precision, certification-intensive segments that supply PLC and semiconductor equipment manufacturers.
Trade flows reveal a persistent deficit in North America, where domestic forging capacity has contracted over the past decade even as automation-related demand has risen — a gap increasingly filled by imports from India and Southeast Asian suppliers.
What This Means for the PLC and Industrial Automation Sector
For procurement professionals and system integrators in the PLC space, the forgings forecast carries tangible implications. Lead times for custom-forged automation components — already stretching in 2025–2026 — are unlikely to normalize before 2030 given the demand trajectory. Second-sourcing strategies and long-term supply agreements will become increasingly critical for OEMs building PLC-controlled machinery.
Pricing pressure is expected to remain moderate but persistent. The IndexBox analysis suggests that forging costs will rise at roughly 3–4% annually in nominal terms, driven by energy input costs and skilled labor scarcity in key production geographies. For PLC panel builders and machine OEMs, this cost gradient should be factored into multi-year project quotations to avoid margin erosion.
Strategic Takeaway: The convergence of automation capex cycles, semiconductor expansion, and constrained forging capacity creates a compelling case for vertical integration. PLC equipment manufacturers that secure dedicated forging supply — either through long-term contracts or captive capacity — will gain a structural cost advantage through 2035. Companies that remain spot-buyers face escalating lead-time risk.
Regional Outlook: Where the Growth Will Concentrate
Asia-Pacific will capture the largest share of incremental forgings demand through 2035, driven by greenfield factory construction in India, Vietnam, and Indonesia. These markets are simultaneously building out their PLC automation ecosystems, creating a self-reinforcing demand loop for forged components. North America and Europe will see growth concentrated in replacement and upgrade cycles rather than new-build volumes, though reshoring trends in both regions could alter this trajectory.
The IndexBox report underscores that the mechanical equipment forgings market is not merely a commodity indicator — it is a leading bellwether for industrial automation intensity. As PLCs proliferate across manufacturing sectors, the physical infrastructure that supports them will continue to drive sustained, measurable demand for the forging industry worldwide.
