Custom Precision Sheet Metal Fabrication | Monitor Enclosure, Display Screen Housing & Medical Equipment Enclosure Custom Machining

We are a full-process precision sheet metal manufacturer specialized in customized housings for monitors, display screens, liquid crystal panel frames and medical instruments. We have conquered pervasive sheet metal manufacturing challenges: thin-plate bending springback & deformation, uneven welding seam flatness, accumulated assembly tolerance mismatches, and defective coating finishes on exposed casings. With automated laser cutting, CNC precision bending, controlled thermal welding and standardized surface coating workshops, we maintain ultra-stable dimensional accuracy and premium cosmetic quality. We provide one-stop OEM & ODM customization for global medical device enterprises, industrial display manufacturers and LCD module suppliers, supporting consistent mass production, shorter lead times and optimized structural cost control.

Product Overview

Our precision sheet metal customization service covers three core product lines:

Monitor Enclosure / Monitor Casing: Complete outer housings for industrial all-in-one monitors, industrial touch control hosts, embedded surveillance displays

Display Screen Housing / Display Panel Enclosure: Screen frame, bezel, protective outer shell and back cover for LCD screens, touch panels, advertising display screens, screen splicing modules

Medical Equipment Enclosure: Structural casings for patient monitors, diagnostic analyzers, portable testing instruments and medical operation control terminals

We customize complete metal structures per your technical drawings or physical samples, covering raw material cutting, precision bending, seam welding, tapping, riveting, deburring, surface finishing and pre-assembly processing. Our finished housings feature rigid structural stability, precise mating tolerances, optional dustproof & electromagnetic shielding performance, and uniform high-grade coating appearance, fully meeting strict dimensional, assembly and aesthetic requirements of display panel industry and medical electronic industry.

Core Competitive Advantages & Technical Problems We Have Overcome

  1. Solve Thin Plate Bending Springback & Housing Warpage (Critical for Display Shells)

    Thin aluminum & cold-steel sheets used for display screen bezels easily produce springback after CNC bending, resulting in irregular outline, inconsistent gap between screen frame and panel, and assembly failure. We adopt customized springback compensation mold design + segmented positioning bending technology, controlling bending angle tolerance within ±0.15°, ensuring flatness consistency for display screen housings and monitor shells, eliminating warpage & uneven gap defects in mass production.

  2. Eliminate Welding Deformation, Pits & Uneven Seams for High-Appearance Display & Medical Casings

    Display front bezels and medical equipment shells require flawless exterior appearance; conventional welding easily triggers thermal deformation, welding pits and rough seams. We apply pulse precision TIG welding plus subsequent precision grinding & polishing to minimize thermal distortion, realize nearly invisible welding joints, meet high cosmetic standards for exposed display & medical housings, and greatly reduce rework rate after surface treatment.

  3. Control Cumulative Tolerance for Multi-Part Assembly Matching

    Display screen assemblies consist of front bezel, middle frame, rear housing and mounting brackets; cumulative machining deviation often causes poor fitting between screen panel and shell. We implement first-article 3D coordinate full inspection, unified fixture positioning for all working procedures to lock tolerance chains, guarantee interchangeability of spare parts, simplify your final screen & equipment assembly work and lower product rejection rate.

  4. Optimize Surface Treatment to Prevent Coating Bubbling, Peeling & Color Difference

    Display shells and medical housings demand scratch resistance, corrosion resistance and uniform coating color. We adopt complete pre-treatment workflow: Degreasing → Pickling → Phosphating → Passivation before electrostatic powder coating, effectively solving paint bubbling, peeling and color inconsistency on welding seams & sharp edges; finished products pass 500-hour salt spray test, suitable for long-term indoor medical and industrial display application scenarios.

  5. Customized EMI Shielding Structure for Electronic Display Products

    For industrial monitors and LCD display modules, we can customize shielding grooves, conductive contact frames and sealing structures in sheet metal design to boost electromagnetic shielding performance, helping your finished products meet EMC certification standards for industrial and medical electronics.

Full In-House Production Strength

  1. Complete self-operated production line: Fiber laser cutting, CNC precision bending, laser welding / precision argon arc welding, tapping, riveting, deburring, grinding, electrostatic powder coating, screen printing and pre-assembly; no outsourced procedures, full quality traceability and reliable delivery schedule control.
  2. Rich enclosure development experience for display & medical industry: We provide early-stage DFM structural optimization suggestions to reduce your material cost, lower processing difficulty and improve production yield for monitor shells and display screen frames.
  3. Multi-stage strict quality control: Raw material incoming inspection → in-process dimensional sampling inspection → finished dimension & appearance full inspection → packaging reliability test for bulk orders, capable of long-term large-quantity framework order cooperation.
  4. Flexible customization options: Available materials: cold rolled steel, galvanized steel, stainless steel, aluminum alloy; customizable overall size, screen opening layout, mounting hole positions, lock structure, shielding design, IP protection rating, surface color & finish, laser engraved brand logo, export neutral packaging.
