From “people finding materials” to “materials finding people” — a warehousing transformation already underway.
8On August 26, the 10th EeIE Smart Expo officially opened at the Shenzhen International Convention & Exhibition Center. Inside the halls, “SMT + Semiconductors + Laser Processing + Smart Warehousing” was presented as one complete manufacturing logic.
On the same day, the National Development and Reform Commission and the Ministry of Transport issued the Implementation Plan for Building the Logistics Network, stating clearly: accelerate the informatization of material reserve facilities, deploy intelligent equipment, and achieve digital-and-intelligent management of the entire inbound, storage, and outbound process.
Signals from the policy side and the industry side are converging — warehousing management in electronics manufacturing has reached a moment when it simply must “switch the algorithm”.
In 2026, policy documents around smart manufacturing have been landing one after another.

Nearly 2,000 exemplary scenarios in areas such as smart warehousing; R&D cycles shortened by 28.4%, production efficiency up by 22.3%, defect rates down by 50.2%.
— Smart warehousing has moved from a “nice-to-have” to a “must-have”.
At the same time, industry data reveals another side: in 2025, global sales of SMT material towers reached about USD 4.5 billion, and are projected to reach USD 4.77 billion. The market is growing, but the driving force is precisely the unsustainability of the traditional model.
Hard to Hire
Hiring and retaining warehouse staff is listed among the toughest operational problems to solve.
Hard to Manage
Material types easily number in the thousands; inventory accuracy generally hovers around 95%; two or three wrong-material incidents per month are the norm.
High Costs
A single wrong-material incident costs RMB 40,000–60,000 — over a year, that adds up to a million-level cost black hole.
What matters even more: electronics products are moving toward high variety, small batches, and fast iteration, and SMT line changeovers are happening ever more frequently. The traditional warehouse’s “people finding materials” model — people memorize where the materials are, go find them, verify them, and take them away — sees its error rate climb exponentially during changeover peaks.
What smart material racks set out to solve is exactly this underlying logic problem.
The SMD smart electronic material rack is an intelligent reel-storage and management device built for SMT electronics manufacturing. Through electronic labels, light guidance, and barcode recognition, it manages reel position, quantity, batch, and status in real time with error-proof control. It has upgraded from a mere “storage tool” into “a line-side materials operations node”.
Global SMD Smart Material Racks
$548M
About $341M in 2025, projected to reach $548M by 2032 — a 7.1% CAGR.
China’s Smart Warehousing Equipment
RMB 86B+
The market has already surpassed RMB 86 billion, growing at an 18.7% CAGR — the fastest pace in the world.
The growth logic is clear: when changeover frequency rises from a few times a day to dozens, when material types grow from a few hundred to a few thousand, and when hiring costs shift from “an expense” to “a structural constraint” — the marginal cost of the manual model is soaring, while the marginal cost of smart racks is falling.
What SUNNTOL’s induction smart material rack does is carry the “materials finding people” logic down to every single storage slot.

Serving Industry-Leading Customers
Largest single-customer deployment exceeds 100 units · A mature solution proven by mass production
In 2026, the direction of policy is set and the signals of the market are clear. With 35,000 smart factories already built nationwide, with smart warehousing named among nearly 2,000 exemplary scenarios, and with eight ministries jointly calling to “accelerate the digital and intelligent transformation of logistics facilities and equipment” — the electronics factory’s “materials ledger” truly does need a new algorithm.
From “people finding materials” to “materials finding people”,
what changes is not just the efficiency numbers,
but the way an entire industry operates.
What SUNNTOL’s induction smart material rack does
is to turn this transformation from“something that should be done”
into“something that simply gets done”.
