Custom Industrial Sheet Metal Chassis Housing Processing Service
HPS provides Custom Industrial Sheet Metal Chassis Housing Processing Services for global OEMs. We specialize in fabricating complex internal structural components, such as the hard drive cage sub-assembly shown, as well as full external enclosures.
Utilizing Trumpf CNC punching and bending technology, we transform raw SECC/SGCC steel into high-precision chassis parts with tolerances as tight as ±0.1mm.
Our Xiamen-based facility operates under IATF 16949 quality standards, ensuring that every bracket, cage, and housing meets the rigorous demands of industrial computing and server applications.

Our Custom Industrial Sheet Metal Chassis Housing Processing Service provides high-precision, application-specific metal enclosures for industrial equipment, electronic systems, and automation solutions.
This service focuses on OEM & ODM sheet metal manufacturing, delivering non-finished, custom-fabricated chassis housings designed strictly according to customer drawings, samples, or technical requirements.
With advanced fabrication capabilities and experienced engineering support, we help B2B clients reduce development risk, improve structural reliability, and achieve consistent production quality.
What Is an Industrial Sheet Metal Chassis Housing?
An industrial sheet metal chassis housing is a structural metal framework or enclosure used to:
Unlike finished products, these chassis housings are custom-fabricated components, widely used in industrial, commercial, and infrastructure-level equipment.

Key Features & Advantages
Fully Custom Sheet Metal Fabrication
Manufactured strictly to customer drawings, 3D files, or samples to ensure accurate dimensions and functional compatibility for OEM projects.
Engineering-Oriented DFM Support
Professional DFM optimization improves structural strength, assembly efficiency, and cost control at the design stage.
Complex Structural Forming Capability
Capable of forming guide rails, locking tabs, and EMI grounding features in a single continuous process using precision CNC tooling.
Industrial Material Expertise (SECC / SGCC)
Electro-galvanized steel provides corrosion resistance and conductive cut edges for reliable EMI / EMC performance.
Precision Assembly Services
Riveted sub-assemblies using TOX or PEM fasteners reduce final assembly time on customer production lines.
Stable Quality & Scalable Production
Consistent quality for OEM programs, supporting prototypes to 10,000+ unit mass production.
Confidentiality & IP Protection
Strict procedures protect customer designs and proprietary structures.

FAQ
Q: What material is best for internal chassis parts?
A: We recommend SECC (Electro-Galvanized Steel). It requires no painting, resists rust, and maintains surface conductivity—essential for EMI shielding in industrial electronics.
Q: Do you assemble the brackets before shipping?
A: Yes. We provide riveted assembly (using TOX/PEM fasteners) and spot welding. We deliver ready-to-install sub-assemblies to your factory, reducing your final assembly time.
Q: What tolerances can you achieve?
A: We follow ISO 2768-m standards. For critical features like slide rails or connector cutouts, we achieve ±0.1mm precision using Trumpf CNC equipment.
Q: Can you handle both prototypes and mass production?
A: Yes. We use laser cutting for quick prototypes (1-50 units) and transition to hard tooling (stamping) for cost-effective mass production (10,000+ units).
