Speed Chain Production Line: The Pioneer of Intelligent Upgrading of Manufacturing Industry

In the final assembly workshop of an electronics factory in Dongguan, a silver-grey conveyor line is being used to1.5 metres per secondTransferring mobile phone motherboards. Surprisingly, when the motherboard arrives at the inspection station, the precise blocker makes it instantly stationary, while the pallets in other stations are still flowing at high speed - this "dynamic freezing" technology is the revolutionary breakthrough brought by the multiplier chain production line for modern manufacturing. As the demand for flexible manufacturing has surged, these lines have been upgraded from an "optional configuration" to an "optional" system.Essential Facilities for Survival.

First, why the multiplier chain production line becomes the urgent need of manufacturing industry?

Industry data for 2025 shows that the average order lead time for electronics assembly companies has been reduced to15 daysThe time to complete the process was 45 days three years ago. Behind this time compression is the underlying support provided by the Pexchain technology. Its core value lies in solving the traditional production line'sThe Three Pain Points::

• ​efficiency bottleneck: Ordinary conveyor lines have a capacity of no more than 200 pieces per hour, while the speed multiplier chain passes through theDifferential sprocket structureAchieve workpiece movement at 2.5-3 times the speed of the chain, throughput jumps to 800-1000 pieces/hour.
• ​Lack of flexibilityWhen product iteration occurs, traditional production lines need to be shut down for 2-3 weeks for modification.Modular designThe production model can be switched over within 48 hours by simply adjusting the layout of the workstations.
• ​Spatial constraints: A Shenzhen SMT factory adopts a three-layer speed multiplier chain system inequivalent areaLower capacity increased by 2,10% and vertical space utilisation soared from 35% to 82%.

More critically, the new energy battery industry, due to upgraded safety standards, requires assembly lines withDual capability of anti-explosion and anti-static-This is the area of expertise of the aluminium guide and conductive wheel system of the Speed Chain.

Second, the core advantages of the speed chain analysis

In a comparison test at an automotive electronics factory in Suzhou, the Speed Chain production line demonstrated amazing performance:

Its technological superiority stems from a triple innovative design:

​Differential transmission mechanism: throughDifference between roller and roller radiusAchievement of a speed increase that allows the work plate to reach up to 3 times the speed of the chain while maintaining smoothness
​cumulative operation: Pneumatic stopper with photoelectric sensor forPrecision pause in the flowA home appliance company used this to increase the efficiency of the AOI inspection station by 40%.
​Composite material structure: The combination of extruded aluminium alloy rails + chrome molybdenum steel chain maintains strength while60% weight reduction over all-steel architectureThe power load is lowered.


III. Key technical points in the design of the doubling chain
1. Precise matching of powertrains
A common misunderstanding is the direct selection of high-power motors. In fact, it should be based onTension formulaScientific Computing:

T = [ (m × a) + (m × g × μ) ] × 1.2 
(T is the demand tension, m is the total load, and μ is taken as 0.15-0.25). A robotics company lost $370,000 in average daily capacity due to motor overheating shutdown caused by ignoring the margin factor.
2. Implementation logic of the accumulation function

Photoelectric sensors capture pallet position
PLC (Siemens S7-1200 series recommended) issues a blocking command
​Cylinder response time ≤ 0.3 secondsEnsure precise stopping

In Huizhou TCL LCD production line, the technology makes the defective product interception accuracy rate of 99.8%.

3. Design for environmental suitability

Dusty environments: chooseEnclosed chain cover, Clearance ≤0.5mm
High-temperature workshop (>80°C): ConfigurationHeat-resistant LL6 chainSilicone oil lubrication instead of grease-based lubrication
Static sensitive area: grounded copper row + carbon fibre conductive wheel ofdual protection​


Fourth, the application scenarios of the multiplier chain in various industries
Electronics manufacturing: the game of speed and precision
Mobile phone motherboard mounting line.3x ChainWith 22 metres/minute high-speed transmission, with machine vision positioning, the patch error is controlled within 0.1mm. A company in Shenzhen used this to increase the daily output of iPhone motherboards from 40,000 to 120,000 pieces.
New energy batteries: a revolution in safety
In power cell assembly.Explosion-proof Z4 series chainPassed non-sparking certification with aluminium-magnesium alloy tray to eliminate the risk of ignition and explosion caused by friction. Battery short-circuit accidents dropped by 91% after application by Ningde Times.
Food packaging: a breakthrough in hygiene standards
Chocolate coated line with food grade kraft sheet base tape withStainless steel self-lubricating bearingscombination for grease-free delivery and FDA approval. A European brand used this to reduce the microbiological exceedance rate of its products to 0.03ppm.

V. The Future of the Speed Chain: A New Stage of Intelligent Integration
At the Hannover Messe 2025, a German company demonstrated theEmbedded fibre optic sensing chain--Distributed optical fibres are embedded in the chain links to monitor tension fluctuations in real time. When the local stress exceeds the limit, the system automatically adjusts the inverter output to prevent chain breakage accidents. This kind ofPredictive maintenanceTechnology reduces downtime by 701 TP3T.
What's more, it's worth paying attention toDigital twin access. By collecting 12-dimensional parameters such as motor current, chain temperature, etc., the virtual mapping of the physical production line is constructed. In the trial production stage can simulate the operating state under different loads, the mass production ramp-up period from 3 weeks to 5 days. I found in the research: the first to apply the technology of the enterprise, the failure rate of new product introduction decreased by 58%.

Self-questioning: six key questions for the speed chain production line
​Q1：Why is Speed Chain more space-saving than traditional conveyor line?​

Its multi-layer three-dimensional design (e.g., 3-layer Z-shaped layout) saves 60% of floor space compared to single-layer lines, andvertical handlerAchieve seamless layer transfers.

​Q2: Is the higher initial investment worth it?​

Zhuhai, an electronics factory data: times the chain production line costs about 2.4 million, but 18 months that is back to the capital - due to yield increase of 2.1% + manpower reduction of 65%.

​Q3: How is the maximum load determined?​

Calculate the breaking strength (e.g. 75kgf/m for WCHE5) and take 10 times the safety factor, and check the flexural rigidity of the pallet.

​Q4: Special requirements for maintenance?​

Chain elongation is tested every three months for the first year (>2% requires tensioning), using theStroboscope Calibration SynchronisationThe use of high-pressure water jets directly into the bearing housing is prohibited.

​Q5: Is it compatible with shaped workpieces?​

Automotive sensors with a radius of curvature of 3 mm were successfully transported by means of customised magnetic trays (suction force ≥ 160 N/cm²) or vacuum fixtures.

​Q6: Future technological breakthroughs?​

Self-healing links (microencapsulation technology) and graphene conductive layers will solve wear and tear and static electricity challenges, with commercialisation expected by 2026.



In the digital war room of a sanitary ware factory in Zhejiang Province, the real-time data of the production line of the speed chain jumps on the big screen: 98.7% equipment utilisation rate, 0.23% failure rate, the output rhythm of 17 pieces per minute... Behind these figures, it is a high-speed channel that creates 120,000 yuan output value per hour. When the manufacturing industry enters the era of "second-level competition", Speed Chain is not only an efficiency tool, but also a Noah's Ark for enterprises to cross the cycle.
