简体中文 "Why is a multiplier chain bought from the factory next door at $3,000 a metre quoted at 8,000 when it's my turn?"This problem is like a newbie how to quickly increase the powder like a big head - the surface look are chain, inside the water is deep enough to open the boat! Today we will break open the rubbing said clearly, 2025 latest market + pit avoidance formula is here, after reading you can also be half a connoisseur.
First, the truth of the price chaos: four types of configuration set the price of life and death
I just helped customers to purchase was also pitched, and later figured out the door: industrial-grade speed chain is divided into four grades.Differences of up to 10 times::
-
Basic Economy ($1500-2500/m)
- for what purpose?: Assembly of small home appliances, courier sorting (light load scenarios)
- Unboxing: Carbon steel track + ordinary motor, speed ≤5m/minute
- hidden pitChangzhou, a factory price 2800 yuan / metre, but the installation fee charged 30%! The actual cost soared to 3640 yuan!
-
Factory Dog Main Model ($2500-5000/m)
- carry a job on one's shoulder: Automotive parts, mobile phone assembly (covering 80% requirements)
- Conscientious Configuration: Aluminium alloy track + inverter motor + base tensioning
- market price: 1688 wholesale mid-range goods concentrated in 2000-3500 yuan / metre, 3500 yuan grade the most stable
-
Tudor Premium ($5,000-10,000/m)
- playful scenario: New energy batteries, heavy machinery (same model as Tesla production line)
- What's so expensive?Stainless steel rail expensive 30%! Servo motors add 2000+ per metre!
- case (law): A triple speed chain with electric conveyor function, the base price of 5,000 yuan / metre, plus function and then up 15%
-
Burning customised models (10,000+/m)
- for showing off: Medical aseptic workshop, chip production line
- An inside look at the sky-high prices: Integrated robot arm + AI QC module, commissioning fees alone account for 40% cost
II. Anatomy of a cost: six major money-burning items, item by item
Spend 3,000 or 8,000? Read this table to save 30% budget:
| cost item | Price impact | Don't get caught in the trap. |
|---|---|---|
| Rail Material | Carbon steel < aluminium alloy < stainless steel (difference 30%) | Don't touch stainless steel for non-food plants! Aluminium is good enough. |
| drive system | Normal motor → servo drive (+2000/m) | Speed ≤10m/min Selection of inverter motor |
| octave ratio | 2x speed → 3x speed (+15% cost) | Don't chase 3x speed for non-precision assembly |
| functional module | Automatic tensioning/electrical transport (+10%/item) | Delete useless features before signing the contract! |
| Brand premiums | Imported vs Domestic (Difference 50%) | Domestic first tier (e.g. Changzhou manufacturers) are more cost-effective |
| the length trap | <30 metres unit price skyrocketed | Single line over 40 metres at a direct price reduction of 15% |
A case of blood and tears: Shandong factory greedy cheap to buy "4500 yuan / metre" equipment, the results ofThe contract doesn't specify the load parameters.The chain on the production line was slipping wildly, and we lost $50,000 in one day of downtime!It must be written in black and white: maximum load capacity, speed error ± a few millimetres!
Third, the connoisseur price formula: three steps to uncover hidden costs
Don't be fooled by sales again! 2025 True Cost =Base price x (1 + material factor + function factor)
- basic price: Selection by length (15% off base price for 40 metres of line body)
- Material Coefficient: Carbon steel 0 | Aluminium alloy 0.1 | Stainless steel 0.3
- Functional coefficient: Servo drive +0.2 | Automatic tensioning +0.1 | Charged transport +0.15
practical calculation::
You need to buy 30m aluminium doubler chain with servo drive
Market base price 2500 RMB/m (40m price x 1.15)
Material factor selection aluminium alloy +0.1
Function factor servo drive +0.2
True cost = 2500 x (1+0.1+0.2) = 3250 RMB/m
Offer over 4000?
IV. Soul Strike: does this money have to be spent?
"Speed less than 8m/min? Get it done for $800/m for a regular roller line!"The core of the speed chain is to make the workpiece plate run faster than the chain (2 times the speed of the workpiece plate = 2.5 times the speed of the chain), if the production line does not need the characteristics of the "chain walks slowly, the workpiece runs fast", change the ordinary conveyor line to save 60%!
A final shot of conscience.Those quoted 8000 + / m of "high-end goods", the cost of at least 35% is a brand premium. Remember the three principles.The length is not enough to put together a single, non-high-precision do not touch the servo, the contract parameters to the millimetre key--After all, our money has to be turned into a machine, not into a year-end bonus for sales!
