Food plant purchasing execs test themselves: nylon doubler chain saves $30,000, but stainless steel gets the FDA nod!

"Just been approved by the boss budget overruns, suppliers and urged to set the chain material - choose nylon for fear of carrying steam, choose stainless steel meat price!" Last week, the old Zhang's groan, out of how many factories people's tangled. Today we will useReal production line scene, the battle of breaking and kneading nylon and stainless steel doubler chains for value for money!

Scenario 1: Electronics factory on a tight budget, nylon chain true fragrance warning!

​contexts: A mobile phone case assembly line in Shenzhen, dry environment at room temperature, transfer weight <5kg/board
​price competition(factory direct price):

  • ​nylon chainZhejiang Zhodun reported 29 yuan / piece (including rollers), Wuxi Mancheng 210 yuan / piece (custom models)
  • ​Stainless steel chain: Shenzhen Foster 247 yuan/m, Yancheng Shengcheng 115 yuan/m

​Old Zhang is counting on his fingers.::
A 20-metre production line with nylon chains.580Stainless steel chain2,300.! Saved enough money to buy a used tester!
​labour market: Nylon temperature-resistant upper limit of 85 ℃, hot air welding area should not be used! A factory to save the wrong place, chain deformation shutdown day loss of 20,000 yuan.

Scene 2: meat processing plant, stainless steel is expensive for a reason

​contexts: A ham sausage factory in Hunan, high temperature rinsing + weak acid environment, FDA flight inspection frequent visitor
​the choice between life and death::

  • Nylon chain: easy to deteriorate in the presence of oil and grease, roller jamming after corrosion by acid mist (replacement time 2 hours/time)
  • 304 stainless steel chain: Hunan local factory offer lower than Guangdong 30%, resistant to 120 ℃ high temperature rinsing, passivation treatment resistant to weak acids

​experience acquired through blood and tears::
A factory used low-priced "stainless steel chain", resulting in insufficient nickel content and rust!Recognise SGS reports::

  • Chromium-nickel ratio ≥18/8
  • Salt spray test＞48 hours
    It's an extra $80 per metre, butPassed with zero defects during FDA raid-That's money that's really saved!

Scenario 3: Heavy-duty line for automotive parts, mix and match is the king of explosives

​contexts: A bearing conveying line in Jiangsu, with high impact forces at local workstations
​miraculous operation::

plaintextmake a copy of
Dry light load section → nylon chain (29 yuan / piece)
Oil heavy-duty section → 304 stainless steel chain (thickened 1.5mm chain plate)
Cleaning section → 316L stainless steel chain (strong alkali resistance)  


​effect: The overall cost is ↓45% compared to the all-stainless steel solution, and the failure rate is instead reduced by 70%!




​Engineer Whisperer::

Don't be fooled by the name "304 stainless steel"!


    

  • ​Wuxi system manufacturers(e.g. Golden Shield) do 1.0mm standard board enough, 115 yuan / metre
    • 

  • ​Yancheng ManufacturerAdd passivation layer to prevent acid mist, only $5 per metre but life expectancy ↑3 years
    • 







The Ultimate Decision Tree: Pick and Choose without Stepping in the Pit


plaintextmake a copy of
1. Ask the environment: oil/acid/high temperature? → Yes, decisively 304 stainless steel (choose Hunan, Yancheng plant)
                ↓ No
2. Look at the load: > 20kg / m? → Yes, choose stainless steel thickened chain plate (1.5mm)
                ↓ No
3. Check the budget: <100 yuan / metre? → Yes, nylon chain to go (recognised PA66 material)
                ↓ No
4. Special requirements: to anti-static? → Carbon black nylon chain; precision? → Shenzhen steel chain  




​personal decision-making moment::

Dry equipment procurement for ten years, have seen too many "save money into burning money" tragedy ---The optimal solution is to make every cent count.!


    

  • Transferring boxes? Doesn't it smell good to add chicken legs to your workers with the money you save on nylon chains?
    • 

  • A sterile pharmacy? The expensive bit of stainless steel isn't enough to cover a fraction of a recall loss!
    
Remember.Hunan stainless steel chain to carry corrosion, Zhejiang nylon chain to fight cost-effective, mix and match used well, the boss chasing you to give you a bonus!
