From Component Processing to Complete Machine Delivery — A Deep Transformation of the OEM Sheet Metal Industry’s Business Model

Three Major Transformation Trends: OEMs are accelerating their upgrade to ODMs: customers no longer merely provide drawings; instead, they require suppliers to participate in structural design, process optimization, and material selection, thereby achieving integrated “design–manufacturing–verification” capabilities. Companies with collaborative CAD/CAM/CAE design capabilities see a significant boost in customer loyalty and pricing power. Surging demand for complete-machine delivery: brands continue to streamline their internal manufacturing processes, with an increasing number of clients requiring sheet-metal firms to handle the entire end-to-end workflow—from component machining and assembly to system integration, commissioning, packaging, and shipment. “Complete-machine suppliers” are thus capturing more high-end orders and market share. Moldless and low-mold processes are becoming mainstream: as product life cycles shorten and design changes become more frequent, customers are generally reluctant to bear the costs and risks associated with mold development. As a result, “moldless or low-mold” technologies such as laser cutting, CNC bending, and flexible stamping have become standard, substantially reducing development cycles and lowering upfront investment. Industry Impact: The traditional “low-price order-taking, extensive processing” model is gradually being phased out; technology, service, and delivery capabilities are emerging as core competitive advantages; and the industry is shifting from “labor-intensive” to “technology-intensive plus management-intensive.”

Green manufacturing has become standard, as the sheet-metal industry accelerates its low-carbon and sustainable transformation.

Under the “dual carbon” goals and global environmental protection requirements, green manufacturing, low-carbon production, and sustainable development have become mandatory priorities for OEM custom sheet-metal enterprises. Key focus areas for industry greening: Energy-efficient equipment and processes: high-power fiber laser cutting (reducing energy consumption by more than 30%), servo press brakes, and intelligent production-scheduling systems that minimize idle runs and waste. Eco-friendly materials and surface treatments: promoting recycled steel, low-VOC powder coatings, and chromium-free passivation as substitutes for traditional oil-based paints and acid pickling–phosphating. High-rate recycling of scrap: closed-loop recovery and categorized utilization of metal trimmings and swarf, boosting material utilization from the conventional 65% to over 90%. Digitalization for carbon reduction: digital twins, AI-driven energy optimization, and paperless production, enabling end-to-end traceability of the carbon footprint. Dual drivers—policy and market: increasingly stringent environmental regulations and the implementation of the EU’s CBAM carbon border adjustment mechanism have made low-carbon capabilities a critical entry threshold for accessing international supply chains. An increasing number of leading customers are incorporating environmental management systems and carbon-reduction commitments into their supplier audit criteria. Trend summary: The overlapping waves of greening, digitalization, and premiumization are propelling high-quality development in the sheet-metal industry. Companies that proactively deploy low-carbon technologies and build green-manufacturing systems will gain a long-term competitive edge in both the domestic and international dual-circulation frameworks.

Powder Coating Process

Powder coating is a surface treatment method in which plastic powder is sprayed onto parts. Commonly referred to as electrostatic powder coating, this process has been widely adopted internationally since the 1980s as an effective decorative technique for metal surface finishing. Compared with conventional spray painting, powder coating offers numerous advantages, including advanced processing technology, energy efficiency, safety and reliability, and vibrant coloration. As a result, it is frequently used in light industry and residential decoration applications. The underlying principle involves charging plastic powder through high-voltage electrostatic equipment; under the influence of the electric field, the coating is sprayed onto the workpiece surface, where the powder adheres uniformly to form a powdery coating. Subsequently, after high-temperature baking, the powder melts and flows to achieve leveling and curing, transforming into a dense, durable final protective layer with varying surface finishes that firmly bonds to the workpiece. Advantages No thinning agents are required, making the process environmentally friendly and non-toxic to humans; the coating exhibits excellent appearance quality, strong adhesion, and high mechanical strength; the curing time during spraying is short; the coating demonstrates significantly superior corrosion and wear resistance; no primer is needed; application is simple and places low demands on operator skill; the overall cost is lower than that of traditional spray painting; in certain applications, electrostatic powder coating is explicitly mandated; moreover, the electrostatic powder-spraying process does not suffer from the common issue of paint running or sagging seen in conventional spray painting. Process Principle The process leverages corona discharge to enable the powder coating to adhere to the workpiece. Specifically, the powder coating is conveyed by a compressed-air system from the powder supply unit to the spray gun, where a high voltage generated by a high-voltage electrostatic generator is applied at the nozzle. Due to corona discharge, a dense cloud of charges forms in the vicinity of the nozzle. As the powder is ejected from the nozzle, it becomes charged particles that are attracted by electrostatic forces to the workpiece, which carries an opposite charge. As more powder is sprayed, the accumulated charge increases until, upon reaching a certain thickness, electrostatic repulsion prevents further deposition, thereby forming a uniform powder coating of consistent thickness across the entire workpiece. The coated part is then heated, causing the powder to melt, flow, and cure, ultimately forming a hard, durable coating film on the surface.

What is a sheet metal part?

Sheet Metal Parts: Sheet metal is a comprehensive cold-working process applied to thin metal sheets—typically less than 6 mm thick—and encompasses operations such as shearing, punching/cutting/combined punching and cutting, bending, welding, riveting, splicing, and forming (e.g., for automobile bodies). A defining characteristic is the uniform thickness of each part. Products manufactured through sheet-metal processes are referred to as sheet-metal parts. The specific meaning of “sheet-metal part” can vary across industries, often serving as a term used during assembly or component integration. Sheet-Metal Materials: A wide variety of sheet-metal materials are suitable for stamping and other forming processes. In the electronics and electrical appliance industry, common sheet-metal materials include: 1. Ordinary Cold-Rolled Steel Sheet SPCC SPCC refers to steel ingots that are continuously rolled by a cold-rolling mill into steel coils or sheets of the desired thickness. SPCC has no surface protection, making it highly susceptible to oxidation when exposed to air—especially in humid environments, where oxidation accelerates, leading to the formation of dark-red iron rust. Therefore, SPCC surfaces typically require painting, electroplating, or other protective coatings before use. 2. Electro-Galvanized Steel Sheet SECC SECC is made from standard cold-rolled steel coils, which undergo degreasing, pickling, electro-galvanizing, and various post-treatment processes on an automated continuous galvanizing line to produce electro-galvanized products. SECC not only retains the mechanical properties and similar formability of ordinary cold-rolled steel sheets but also offers superior corrosion resistance and an aesthetically pleasing finish. As a result, it is highly competitive and increasingly replacing traditional materials in the electronics, home-appliance, and furniture markets. For example, SECC is widely used in computer cases. 3. Hot-Dip Galvanized Steel Sheet SGCC Hot-dip galvanized steel coils are produced by first cleaning and annealing semi-finished hot-rolled or cold-rolled steel, then immersing the material in a molten zinc bath at approximately 460°C to coat the steel surface with a layer of zinc. The material is subsequently tempered, leveled, and subjected to chemical treatments. Compared with SECC, SGCC is harder, less ductile (making it unsuitable for deep-drawing applications), has a thicker zinc coating, and exhibits poorer weldability. 4. Stainless Steel SUS301 SUS301 contains a lower chromium content than SUS304, resulting in slightly poorer corrosion resistance. However, after cold working, it achieves excellent tensile strength and hardness, along with good elasticity, making it ideal for applications such as spring clips and EMI shielding. 5. Stainless Steel SUS304 One of the most widely used stainless steels, SUS304 owes its superior corrosion and heat resistance to its nickel content. It also boasts outstanding mechanical properties, does not harden through heat treatment, and lacks significant elasticity.
