Rectangular Deep Cavity Electronic Housing Stepped Pocket Mirror Bored CNC Precision Machined 0.01mm

This rectangular deep cavity electronic housing is machined from a solid 6061-T6 aluminum billet as a single piece, with a two-level stepped inner pocket, a machined gasket sealing groove around the pocket rim, two threaded M12 connector ports on the side wall and four countersunk cover mounting holes. The design is aimed at enclosures where a square or rectangular deep pocket, a repeatable sealing face and long-term dimensional stability matter more than sheet metal or die-cast construction can deliver. Every cavity and port is generated in one clamping setup on a 4-axis or 5-axis CNC machining center, so the pocket, the groove, the ports and the mounting holes share one datum instead of accumulating tolerance from several operations.

Process discipline, not just machine capability, is what keeps this housing repeatable from the first sample to the thousandth piece. The production route below is standard and can be tailored to your drawing and volume.

Critical features are verified on a coordinate measuring machine against the CAD model, and key dimensions are charted so a trend can be spotted before it becomes a scrap part. Where a drawing calls for a tighter callout on a specific face, we confirm feasibility in the DFM review before quoting the tolerance.

Everything except the machining approach is open to your specification. Non-standard geometry is the normal case for us, not the exception.

• Body size and proportion from your 3D model, 2D drawing or sketch; we can also build the model from your component and interface requirements.
• Pocket type: rectangular, circular, square, stepped or multi-level, with pockets from 5mm shallow to 200mm deep.
• Ports and cutouts: M8 to M25 threaded ports, D-sub, USB, RJ45, HDMI, power jack, antenna, SIM and SD slots, ventilation slots.
• Sealing: gasket grooves, O-ring seats, stepped sealing faces, sealing land flatness specified to 0.02mm.
• Mounting and assembly features: counterbored, countersunk or threaded holes, bosses, ribs, wire routing channels, mating steps.
• Finish and appearance: mirror, brushed, bead blast, clear or colour anodizing, powder coating, laser marking of part numbers.
• Low minimum order: 1 piece for prototyping, then batch or serialized production from the same program.

Send a drawing or model and our engineering team returns DFM feedback, a realistic tolerance callout and a quote, usually within one to two working days. If a feature cannot be held economically, we propose an alternative that keeps function and lowers cost.

Dongguan Changxinda Precision Technology Co., Ltd has been a custom CNC machining supplier since 2008, based in Dongguan, Guangdong, China. We run 4-axis and 5-axis CNC machining centers, turn-mill combined lathes, CNC lathes and milling machines, with about 100 staff including a dedicated programming and quality team. More than 200 customers are served in medical equipment, robotics, automotive, aerospace, automation, laser, LED, lithium battery and precision testing instruments, and 50-60 percent of output is exported. We are ISO 9001:2015 certified, with annual sales in the USD 10-20 million range and in-house inspection using CMM and optical measurement equipment. Deep pocket housings, mirror finished cavities and sealing faces are one of our long-standing specialities because the same capability is used for vacuum, optical and fluid handling parts.

• Monthly capacity above 10,000 pieces on this housing family, with capacity reserved for repeat customers.
• Typical lead time: 3-7 days for prototypes, 7-14 days for small batches of 10-100 pieces, 14-30 days for mass production.
• Programs, fixtures and tooling are kept on file after the first order, so repeat lots start without setup delay.
• SPC charts and a first-article inspection report travel with every lot, so incoming inspection at your end stays short.
• Rush service and scheduled release shipments can be arranged for projects with a fixed line-side date.
• Export packaging: each housing in a foam-lined pocket, master carton with desiccant, palletized for LCL and FCL shipment.

Instrument and controller enclosures, sensor and detector housings, RF and microwave cavity housings, optical and laser module housings, medical device housings, automation controller boxes, robotic joint housings, test fixture bodies and other custom non-standard electronic enclosures that combine a deep pocket, a sealed interface and a machined finish.
