Custom Made Powder Coated Sheet Metal Fabrication Bending Part for Truck/Trailer

Product Description

                 Custom Made Powder Coated Sheet Metal Fabrication Bending Part for Truck/Trailer


Under the pressure of the upper or lower die of the bending machine, the metal sheet first undergoes elastic deformation and then enters plastic deformation. At the beginning of plastic bending, the sheet is free to bend. As the upper or lower die presses the sheet, the sheet and the inner surface of the V-groove of the lower die gradually come close to each other, and the radius of curvature and the bending arm gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies and the sheet are in full contact at three points, and a V-shaped bend is completed.

The products are mainly used in construction machinery, agricultural machinery, forestry machinery, vehicle 
and motorcycle, high-speed railway etc. 
We could also develop new products according to customer's specific requirements.

FAQ

Q1: What information do you need to provide an accurate quote?

A: We need the following for an accurate quote:

Detailed Engineering Drawings: Preferably in DXF, DWG, STEP, or IGES format. 2D drawings must clearly show flat pattern dimensions with all bend lines, angles, directions, and radii.

Complete Material Specifications: Type (e.g., 304 Stainless Steel), grade, thickness, and temper/condition.

Quantity Required.

Surface Finish Requirements: (e.g., powder coat RAL 9010, brushed finish, passivated).

Any Critical Tolerances beyond our standard (±0.5° on bends, ±0.1mm on linear dimensions).

Q2: What is your standard bending tolerance?
A: Our standard bending tolerances are:

Bend Angle: ±0.5 degrees (for angles 90° and others).

Linear Dimensions (between bends): ±0.1mm to ±0.25mm, depending on part size and complexity.

Bend-to-Hole/Feature Position: ±0.13mm.

Flatness (after bending): 0.2mm per 100mm.
Tighter tolerances (e.g., ±0.1° on angles) are achievable with our high-precision machines and specialized tooling, but will affect cost and lead time.

Q3: Can you bend pre-painted, powder-coated, or anodized material without damaging the finish?
A: Yes, but special care and tooling are required. We can bend pre-finished materials by:

Using protective film on the sheet.

Utilizing specialized tooling with polished, radiused surfaces or protective urethane inserts.

Adjusting bending parameters to minimize stretching and abrasion.
Some micro-cracking or minor finish distortion on the outside of the bend radius is often unavoidable, especially with harder coatings. We recommend post-bending painting/powder coating for the highest cosmetic quality.

Q4: What is your Minimum Order Quantity (MOQ)?
A: For custom bending, our MOQ is typically 50 pieces. For simple, small brackets, we can go as low as 10-25 pieces. For prototype or development projects, we accept single-piece orders. Larger volumes (500+) receive significant per-piece cost reductions.

Q5: What is your typical lead time?
A: Lead times vary:

Prototypes (1-10 pcs): 5-10 working days after drawing approval.

Small Batch (10-100 pcs): 10-15 working days.

Production Run (100-1000 pcs): 15-25 working days.
Lead time begins after we receive approved drawings and deposit.

Q6: What quality control measures do you have?
A: Our QC includes:

First Article Inspection (FAI): Full dimensional check with CMM or precision tools.

In-Process Checks: Spot-checking bend angles and key dimensions.

Material Certs: Verification of material grade.

Final Audit: Visual and functional check before packing.
We provide FAI reports and welcome customer or third-party inspection.

Q7: How do you package bent parts to prevent damage?
A: We use protective packaging:

Individual wrapping in bubble wrap or foam.

Cardboard separators between parts.

Sturdy export cartons or wooden crates for heavy/large items.

Edge protectors for sharp bends.
