Q1: Are you trading company or manufacturer?
A: We are factory.
Q2: How do I choose the right protective cover/drag chain model?
A: The selection mainly depends on the following parameters:
Stroke length (protective cover expansion ratio/drag chain bending radius)
Load type (number of cables, oil pipe pressure)
Environmental requirements (temperature resistance, water proof, corrosion resistance level)
We provide a free selection tool and one - on - one guidance from our engineers.
Q3: Which is better, a nylon bellows cover or a stainless steel bellows cover?
A: It depends on the application:
Nylon covers: Lightweight, corrosion - resistant, and cost - effective, suitable for general industrial environments.
Stainless steel covers: High - temperature and impact - resistant, suitable for heavy - load, highly corrosive environments (such as electroplating and chemical processing).
Q4: How do I calculate the bend radius of a drag chain?
A: The formula is cable diameter × 10 (for example: a cable diameter of 20mm → a minimum bend radius of 200mm). We can provide CAD simulation verification services.
Q5: Do you support non - standard customization? How long is the turnaround time?
A: We support full customization, including:
Dimensions (extra - long/special - shaped cross - sections)
Material (anti - static, food - grade, etc.)
Mounting method (magnetic, quick - release, etc.)
Standard customization timeframe is 7 - 15 days, and expedited orders can be shortened to 3 - 5 days.
