Custom Sheet Metal Fabrication for Smart Equipment Housings, Multimedia Device Enclosures, Cold Rolled Steel & Galvanized Steel Shell Custom Machining

We are a full-process precision sheet metal manufacturer specializing in customized housings for intelligent automation equipment, multimedia interactive devices, adopting cold rolled steel and galvanized steel as mainstream raw materials. We have solved typical industry processing challenges: thin plate bending springback & deformation, accumulated assembly tolerance mismatch, welding thermal distortion, poor anti-rust performance of ordinary coating, and inconsistent dimensional consistency for multi-batch mass production. With self-owned laser cutting, CNC bending, precision welding and standardized surface treatment workshops, we strictly control assembly precision and exterior cosmetic quality. We deliver one-stop OEM & ODM customization service for intelligent equipment manufacturers, multimedia terminal brands and system integrators worldwide, with stable mass production capacity, optimized structural cost and controllable delivery cycle.

Product Overview

Our customized sheet metal service focuses on three major enclosure product lines:
  1. Smart Equipment Metal Housings: Outer casings for industrial controllers, automated detection equipment, access control terminals, intelligent monitoring hosts, touch all-in-one machines, IoT gateway devices and automated cabinet bodies
  2. Multimedia Device Enclosures: Shells for advertising players, query kiosks, interactive touch terminals, conference all-in-one machines, audio & video control hosts, digital signage and multimedia distribution equipment
  3. Cold Rolled Steel & Galvanized Steel Custom Shells: Custom blanking, bending, welding and coating structural housings made from SPCC cold rolled steel, SGCC galvanized steel, customized according to customer drawings or samples, widely used for electrical protection, equipment support and internal structural brackets
We provide full-process fabrication including raw material cutting, precision punching, CNC bending, argon arc / laser welding, tapping, riveting, deburring, electrostatic powder coating, silk printing and pre-assembly. Our finished shells feature stable structural rigidity, precise assembly fit, excellent anti-corrosion and anti-rust performance, neat appearance, fully meeting strict dimensional, aesthetic and long-term service requirements of intelligent and multimedia equipment industries.

Core Competitive Advantages & Technical Difficulties We Have Overcome (Differentiated Selling Points)

  1. Resolve Thin Plate Bending Springback & Housing Deformation Defect

    Thin-gauge cold rolled and galvanized steel sheets are prone to obvious springback after bending, causing irregular outline, uneven panel gaps and assembly jamming. We adopt customized springback compensation mold design + segmented positioning bending process, control bending angle tolerance within ±0.15°, ensure flatness consistency of smart and multimedia equipment shells, eliminate warpage and uneven gap defects during mass production, greatly improving assembly yield.

  2. Eliminate Welding Thermal Deformation, Welding Pits & Visible Seams for High-Appearance Equipment Shells

    Multimedia and intelligent equipment exposed housings have ultra-high requirements for exterior finish; conventional welding easily causes thermal deformation, pits and rough welding traces. We adopt pulse precision TIG laser welding + subsequent fine grinding & deburring process to minimize heat affected zone deformation, realize nearly invisible welding seams, reduce post-coating rework rate, and satisfy high-grade appearance standards for commercial terminal housings.

  3. Control Cumulative Dimensional Tolerance for Multi-Part Matching Assembly

    Equipment shells consist of front panels, middle frames, rear housings and mounting brackets; cumulative machining deviation often leads to poor fitting between screen, circuit board and casing. We implement first article 3D full coordinate inspection, unified fixture positioning for all working procedures to lock tolerance chain, guarantee interchangeability of spare parts, simplify your final assembly work and lower product rejection rate.

  4. Upgrade Galvanized Steel Surface Treatment to Solve Coating Peeling & Edge Rust Problems

    Galvanized steel surface has passive film that easily causes poor paint adhesion, bubbling and peeling, and cutting edges are prone to rust after long-term use. We deploy targeted pre-treatment process for galvanized substrates: special degreasing + surface activation + phosphating passivation before powder coating, effectively enhance coating adhesion; finished products pass 500-hour salt spray test, effectively extending service life for indoor and semi-outdoor equipment scenarios.

  5. Stabilize Batch Consistency for Large-Volume Repetitive Orders

    Long-term bulk orders often suffer dimensional fluctuation between batches due to manual positioning errors. We adopt fixture standardized positioning + program locked machining parameters, implement sampling inspection for each batch of raw materials, semi-finished products and finished products, keep dimensional deviation stable in long-term repeated orders, suitable for large-scale mass production cooperation for intelligent and multimedia equipment brands.

Full In-House Production Strength

  1. Complete self-operated production line: Fiber laser cutting, CNC precision bending, laser welding / argon arc welding, CNC punching, tapping, riveting, deburring, electrostatic powder coating, screen printing and pre-assembly; no outsourced processes, complete production traceability and reliable delivery schedule control.
  2. Rich enclosure development experience for smart & multimedia industry: We provide early-stage DFM structural optimization suggestions to reduce material cost, lower processing difficulty, improve production yield and rationalize internal wiring layout for your equipment shells.
  3. Multi-stage strict quality control system: Raw material incoming inspection → in-process dimensional sampling inspection → finished dimension & appearance full inspection → packaging reliability test for bulk orders, capable of long-term framework order cooperation.
  4. Flexible customization options: Material options: SPCC cold rolled steel, SGCC galvanized steel, stainless steel, aluminum alloy; customizable overall dimension, screen opening layout, mounting hole position, lock structure, ventilation structure, surface color & finish, laser engraved brand logo, export neutral packaging.
