Electronic Equipment Cover High Pressure Die Casting For Indoor Electronic Device Enclosures
This Electronic Equipment Cover is a core protective and shielding component designed for indoor electronic device enclosures, industrial control cabinets, communication equipment housings, and precision instrument chassis. It is manufactured by our in-house High Pressure Die Casting + CNC precision machining process to achieve high strength, precise mating geometry, and reliable EMI shielding continuity. The use of ADC12 aluminum alloy provides an excellent balance of high strength, superior electromagnetic shielding performance, and lightweight construction. The high-pressure casting process ensures excellent surface finish, tight dimensional consistency, and the ability to form thin-walled, complex geometries with integrated ribs, bosses, and snap-fit features.
Matech's one-stop approach, covering mold design, high pressure die casting, CNC machining (mating surfaces, mounting holes, connector cutouts), shot blasting surface treatment, dimensional inspection, and engineered packing, ensures this equipment cover offers excellent dimensional accuracy on mating interfaces, tight flatness tolerances on sealing surfaces, and a ready-to-assemble finish — performing reliably in demanding indoor electronic enclosure applications.

Our Advantages
Technical Advantages
Mold design and fabrication, high pressure die casting workshop, CNC machining, surface treatment, and inspection lab — all centralized under one roof. No outsourcing. From molten aluminum to finished and surface-treated part, we maintain full control over lead time, quality consistency, and batch traceability.
Before tooling production begins, we provide a detailed DFM report covering mold filling analysis, solidification behavior, draft angle optimization, thin-wall feasibility, and machining allowance recommendations. For electronic covers like this ADC12 component, we focus on flatness control across large mating surfaces, rib layout to prevent warpage after ejection, and gate placement to minimize porosity in sealing and mounting areas.
We specialize in thin-walled, complex-geometry aluminum die castings — such as electronic covers, enclosures, heat sink housings, and connector shells. Our HPDC process delivers excellent surface finish, precise dimensional consistency, and the ability to form integrated ribs, bosses, and snap-fit features in a single operation. We work with ADC12, A380, A360, and other standard or custom aluminum alloys to match your strength, shielding, and thermal requirements.
Service Advantages-总部接待区 1 拷贝
Material Advantages
We charge only certified primary aluminum ingots into our electric melting furnaces. Chemical composition is spectrometer-verified and adjusted in real time before casting. Degassing and fluxing practices ensure clean molten metal with low inclusion content — critical for maintaining consistent ADC12 mechanical properties and surface quality across high-volume die casting production.
Every production batch is identified by a unique heat number. Chemical composition reports, mechanical test records (tensile strength, hardness, elongation), and dimensional inspection data are compiled into a traceable dossier — from ingot lot to finished cover.
We work with a comprehensive range of die casting aluminum alloys — ADC12, A380, A360 — and can tailor alloy selection to your specific requirements. Whether your application demands electromagnetic shielding, thermal conductivity, corrosion resistance, or thin-wall strength, we match the alloy and process parameters to your needs.
Service Advantages
A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage and a single point of contact for all technical and commercial matters.
Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project. For die-cast covers, first-article inspection reports including dimensional layout and flatness measurement are provided before batch production begins.
Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support. Flexible MOQ with pilot order options available for new die-casting projects.
