Waterproof and dustproof aluminum alloy cases with customizable liner colors available!
This #161 small aluminum alloy portable protective case supports full-process OEM & ODM customization. It features a thickened aluminum alloy frame paired with diamond-pattern ABS panels, thickened anti-collision corner protectors on all four corners, and a lightweight, portable structure fitted with an integrated central non-slip handle, double latches, and rear metal hinges. Its compact inner cavity is ideal for carrying precision testing accessories, small measuring instruments, hardware tools, digital accessories, jewelry samples, and small medical supplies. A fabric storage mesh bag is built into the case lid, and the smooth empty inner compartment allows optional custom shock-absorbing foam inserts as needed.
External Dimensions: 400×235×120mm (15.75”*9.25”*4.72”)
Usable Internal Dimensions: 380×215×98mm (14.96”*8.46”*3.86”)
Net weight of the case: 1.75KG. Boasting a lightweight yet sturdy construction, it provides reliable portable protection for small precision items during field work, business trips, outdoor sampling, and trade show attendance.
Constructed with rigid aluminum alloy edging and high-density diamond-pattern ABS panels, the case comes with reinforced anti-collision corner guards, dual safety latches, and thickened rear metal hinges. It delivers dustproof, scratch-resistant, and mild shockproof performance, maintaining stable durability under normal room-temperature environments while blocking dust and moisture. An elastic fabric storage mesh inside the lid conveniently holds tiny accessories, and the smooth empty inner chamber is easy to wipe clean with compatible shock-absorbing liners available for installation. Designed primarily for portable storage of small precision goods, the compact inner cavity suits small testing instruments, hardware repair tools, digital photography accessories, sample displays, miniature medical supplies, and jewelry storage. It addresses common pain points including the lack of dedicated storage boxes for small precision components, damage or scattering during transport, and disorganized tiny parts hard to locate. This universal portable aluminum protective case is suitable for inspectors, maintenance technicians, photographers, and business sales representatives.
Box Reinforced with Aluminum Alloy Edging, Lightweight, Drop and Wear Resistant: Equipped with thickened aluminum alloy frames and diamond-pattern anti-slip ABS panels, the case features integrally molded hard anti-collision corner guards at four corners to prevent deformation and scratches from drops and bumps. Adopting an overall lightweight design with a net weight of only 1.75KG, it brings no burden when carried by hand, making it easy to take along for daily commutes and field work.
Dual Latches for Secure Item Storage: Two sets of latches are mounted on the front of the case to safeguard internal instruments and valuable samples, providing reliable protection during exhibitions and business trips. The latches slide smoothly for long-term use without jamming or breaking easily.
Ergonomic Integrated Anti-slip Handle for Comfortable Short-distance Carrying: An integrated curved plastic anti-slip handle sits on the top of the case with reinforced bracket support. Even when fully loaded with small tools and accessories, it distributes pressure evenly to avoid digging into hands, enabling effortless short-distance transport.
Elastic Fabric Mesh Pocket Built into Lid for Classified Storage of Small Accessories: The upper lid comes with an elastic fabric storage pouch for separate placement of screws, data cables, probes and tiny components. These small parts are separated from large instruments inside the cavity to avoid messy scattering, allowing quick and clear access.
Thickened Rear Metal Hinges for Stable Opening and Closing Without Loosening: Double rows of thickened metal hinges are fitted on the rear of the case and firmly fixed with multi-point rivets. The lid opens at a moderate angle, staying tight without loosening or falling off after tens of thousands of opening-closing cycles, extending the service life of the case.
Smooth Empty Cavity for Easy Cleaning, Compatible with Shock-absorbing Liners: The interior features an integrally molded flat black empty cavity with a smooth surface that can be directly wiped clean with a damp cloth when stained with dust or oil. It can be paired with wave-shaped foam, one-piece molded EVA or layered pearl cotton to meet two demands: simple storage and shock absorption protection for precision instruments.
Full-range Customization Services for Enterprises, Suitable for Small-batch Bulk Purchases: The blank flat area on the case panel supports laser engraving and screen printing of corporate LOGOs, product models and brand names. Custom case color options are available for small orders. ODM size adjustment of length, width and height is supported, alongside custom CNC grooved EVA liners. It caters to small-item storage needs across multiple industries including inspection, maintenance, photography and commerce.

Q1: Will the internal instruments get damaged if this aluminum alloy carrying case drops?
A: It is equipped with anti-collision corner protectors on four corners to cushion and protect against minor daily drops. If you store precision instruments, it is recommended to choose an optional EVA or foam liner for better shock resistance. This case is not suitable for heavy falls from high altitudes.
Q2: Can the case be washed with water?
A: The aluminum alloy frame and ABS panel can be wiped with a damp cloth. Long-term soaking is not recommended. Prevent a large amount of water from entering the interior, and make sure the case is fully dried before storing items after wiping.
Q3: Can a complete set of small testing instruments and tool accessories fit entirely inside?
A: Items whose overall length, width and height are smaller than the internal dimensions of 380×215×98mm can be fully contained. For larger-sized accessories, you may consult our factory about the larger aluminum alloy cases of the same series.
Q4: Can individual replacement parts be purchased if the latches, handle or hinges are broken?
A: Latches, handles, hinges and anti-collision corner protectors are all standardized universal parts. Contact customer service and provide your case model, then separate replacement parts will be delivered to you for self-installation.
