Enhance the durability, corrosion resistance, and cosmetic appearance of your sheet metal parts with our professional post-processing treatments.
Parts are left with their natural metal finish. All sharp edges and burrs are mechanically removed for safe handling.
A dry powder is electrostatically applied and cured under heat. Delivers a thick, highly durable, and scratch-resistant protective layer.
An electrochemical process that converts the aluminum surface into a decorative, highly durable, and corrosion-resistant anodic oxide finish.
Coating the metal with a thin layer of another metal (such as Zinc or Nickel) to dramatically improve rust resistance and electrical conductivity.
Optimize your sheet metal CAD designs to ensure high manufacturability, minimize tooling wear, and reduce your production costs.
Design all bends on a single part with the same radius. This avoids machine tooling changes during production, drastically lowering your unit cost.
Keep holes and slots at a minimum distance of 3x the sheet thickness away from the bend line to prevent the hole from stretching or warping during forming.
Ensure the diameter of any pierced holes is at least equal to or greater than the sheet thickness to prevent tooling damage and material deformation.
Our standard lead time for rapid prototyping (1–10 parts) is typically 3 to 5 business days. For medium to high-volume production orders, delivery ranges from 10 to 15 business days, depending on the complexity of assembly and surface finishing requirements.
We follow standard ISO 2768-m specifications for sheet metal fabrication. Generally, we achieve a precision tolerance of $\pm$0.1 mm for fiber laser cutting and $\pm$0.3 mm for CNC press brake bending. Tighter tolerances can be accommodated upon engineering review of your CAD files.
Yes. We offer fully scalable on-demand manufacturing with no strict Minimum Order Quantity (MOQ). Whether you need a single functional chassis prototype or thousands of progressive die stamping parts for mass production, we provide cost-effective solutions for both.
Absolutely. We provide one-stop, turn-key fabrication. Our capabilities integrate laser cutting, bending, and high-strength TIG/MIG welding with in-house hardware insertion (PEM studs and nuts), followed by standard finishes like powder coating, anodizing, or plating to deliver a complete, ready-to-use assembly.
To minimize your unit cost, we highly recommend keeping all bend radii uniform throughout the part to eliminate machine tooling changes. Additionally, ensure that all pierced hole diameters and the distance from holes to any bend lines are at least equal to or greater than the sheet thickness to prevent tool wear and material warping.
Once we receive your design files, our senior manufacturing engineers will manually perform a comprehensive DFM review and deliver an accurate, optimized quote within 24 hours.
