Frequently Asked Questions by Global Engineering Teams
Clear engineering and procurement insights addressing custom sheet metal enclosure manufacturing, lead times, tolerances, and quality guarantees.
What tolerances can your sheet metal fabrication process maintain?
Our high-precision fiber laser cutters achieve dimensional cut tolerances of ±0.05 mm (0.002 in). For multi-axis CNC press brake bending, we hold standard angle tolerances to ±0.5° and linear hole-to-hole dimensions to ±0.1 mm. Critical machined interface features can be held down to ±0.005 mm using post-fabrication CNC milling.
Which surface treatments do you offer for weatherproofing and EMI shielding?
We provide a comprehensive array of finishing options including electrostatic architectural powder coating (60-100 microns thick), anodizing (Type II clear/black and Type III hardcoat), chromate conversion coating (MIL-DTL-5541), electroplating (zinc, nickel, tin), wet painting, and electropolishing for stainless steel. Conductive gaskets and plating are available for specialized EMI/RFI shielding protection.
How do you guarantee IP65, IP66, or NEMA 4X ingress protection levels?
Ingress protection is achieved through continuous automated robotic welding (TIG/MIG/Laser), precision corner seam sealing, continuous polyurethane foam-in-place (FIP) gasketing, and stringent water immersion and dust chamber testing. Every IP-rated enclosure design undergoes rigorous prototype validation before mass manufacture.
What is the standard lead time for prototype samples versus mass production?
Rapid sheet metal enclosure prototypes are typically completed and inspected within 3 to 7 business days following DFM approval. Mass production runs generally ship within 2 to 4 weeks, depending on tooling requirements, surface finish complexity, and order volume scale.
What CAD drawing file formats do you accept for DFM review?
We accept 3D solid model file formats including STEP (.stp), IGES (.igs), SolidWorks (.sldprt), Parasolid (.x_t), and Autodesk Inventor (.ipt). 2D vector files such as DXF, DWG, and vector PDFs are required for specifying thread callouts, bend radii tolerances, hardware insert types (PEM), and finish callouts.
How do you protect client IP during the engineering quote process?
We strictly protect client data under mutual Non-Disclosure Agreements (NDAs). Your 2D/3D CAD files are stored on secure internal servers and are exclusively accessed by authorized project engineering staff. Data is never shared with third-party vendors or external entities.
