I. Common Price Ranges
Price ranges for common types. According to industry quotes, the price of non-standard assembly lines varies significantly by type: double-speed chain conveyors are priced at 1,000–2,000 RMB per meter; a basic single-layer line (under 16 meters, excluding motors and controls) costs approximately 30,000–80,000 RMB;
a workbench-style belt assembly line for electronics workshops costs about 10,000–13,500 RMB; a custom TV or mobile phone assembly line starts at around 130,000 RMB; and a minimum viable SMT (Surface Mount Technology) production line starts at 500,000–800,000 RMB. Although all are classified as “assembly lines,” costs can range from 10,000 RMB to tens of millions.

Six Cost Modules
Six modules of cost composition.
Industry analysis breaks down the cost of non-standard equipment into six parts: direct material costs account for 40%–60% (including mechanical structural components—aluminum profiles, stainless steel, carbon steel, fasteners—and electrical components like PLCs, HMIs, and sensors); processing fees (CNC machining, bending, welding, coating) account for 20%–30%; design fees account for 15%–20% (covering requirements analysis, mechanical and electrical drawings, and software programming—though many manufacturers do not charge for this separately, embedding it in the total price instead); inspection and packaging fees are about 2%–5%; installation and commissioning fees are about 5%–10%;
plus taxes and reasonable profit margins. Materials and processing represent the largest shares.
III. Complexity Tiers
Price tiers based on complexity levels.
Based on industry experience, systems are categorized by complexity: simple belt conveyor lines range from 30,000 to 80,000 RMB; medium-complexity assembly lines (featuring accumulating chain conveyors, electrical controls, and standard workstations) range from 150,000 to 300,000 RMB; complex integrated lines incorporating robots, visual inspection, and MES connectivity exceed 500,000 RMB; and high-end precision machining centers or automated warehousing systems can reach the tens of millions. The total price rises in tiers with the addition of each functional module (e.g., 80,000–150,000 RMB per robot; tens to hundreds of thousands per vision workstation).
IV.
Major Hidden Costs
Labor and design constitute the major hidden costs.
Industry experience shows that price discrepancies often stem from these hidden expenses: for a project in the 1-million-RMB range, material costs account for approximately 30% (300,000 RMB); labor costs—covering initial consultation, detailed planning, assembly, electrical wiring, and commissioning—amount to at least 100,000 RMB for a three-person team working from start to finish (a minimum of three months); R&D and design fees can exceed 50% of the total in development-heavy projects (involving schematics, source code, and hundreds of hours of iterative debugging); and a risk contingency fund of about 20% is required to handle design changes and system integration/debugging.
Low-ball quotes often cut corners in these specific areas.
V.
Budgeting Recommendations
When preparing a budget, industry best practice dictates starting with a detailed requirements list: conveying method (belt, accumulating chain, roller, or overhead), number of workstations, load weight, cycle time requirements, inclusion of robotics and vision systems, tier/brand of electrical controls, and safety protection levels. Next, work backward based on cost composition: materials (40%–60%), machining/fabrication (20%–30%), design (15%–20%), plus commissioning, testing, and taxes. Require suppliers to provide itemized quotes for line-by-line verification to avoid vague, lump-sum pricing. For specialized production lines such as SMT, refer to starting prices of 500,000 to 800,000 RMB for a complete line solution.
Conclusion
How much does custom assembly line equipment cost? The answer is “anywhere from 30,000 to tens of millions, depending on complexity”: a simple accumulating chain conveyor line costs 30,000–80,000; an electronic belt conveyor line, 10,000–13,000; a mid-range assembly line, 150,000–300,000; a complex integrated line featuring robotics and machine vision, over 500,000; an SMT production line starts at 500,000–800,000; and large-scale automation systems can reach the tens of millions. The cost structure typically breaks down as follows: materials (40%–60%), machining/processing (20%–30%), design (15%–20%), commissioning (5%–10%), and inspection/packaging (2%–5%).
Industry-wide, price variations stem primarily from “hidden” costs—specifically labor and design fees (e.g., a three-person, three-month project costs around 100,000, with development-heavy design fees potentially exceeding 50% of the total).
To secure a fair price free of “fluff,” one should first list functional requirements, work backward based on the cost structure, and request itemized quotes for detailed verification.
