The case is framed entirely with thickened aerospace-grade aluminium-magnesium alloy profiles and fitted with wear-resistant aluminium panels with diamond patterns. The four corners are equipped with integrally stamped arc-shaped metal anti-collision guards. An integrated 3-digit combination lock is mounted on the front for keyless anti-theft locking. A full-circle embedded rubber sealing strip delivers protection against dust, splashes, drops and compression. The single-side metal support hinge keeps the lid open steadily without bouncing back. The basic interior is lined with fine black flocking fabric, and two types of standard inner linings are available. The well-proportioned medium-sized cavity is perfect for keeping financial seals, storing field testing equipment, holding small precision parts carried by maintenance workers, carrying outdoor photography accessories, and storing curios and jewellery at home. It addresses common problems including lack of anti-theft storage for valuables, bumps to precision instruments during transit, component corrosion caused by dust and moisture, and lost seals due to improper storage. This password-protected anti-theft aluminium storage case is widely used by administrative and finance staff, testing technicians, electronics repairmen and digital enthusiasts.
Thickened aluminum-magnesium alloy frame with diamond texture plus rounded metal corner guards, wear-resistant, drop-proof and deformation-resistant: The whole case is enclosed with complete aerospace-grade aluminum-magnesium alloy edges with anti-slip diamond embossing on the surface, which is fingerprint-proof, scratch-resistant and highly durable. Fully covered stamped rounded metal anti-collision corner protectors are installed on four corners of the case to disperse impact force during dropping, stacking and collision, preventing the case from denting or bending. Featuring an all-silver brushed industrial appearance, it is suitable for business office work and field construction operations.
Integrated 3-digit combination lock for keyless anti-theft and greater convenience: A 3-wheel combination lock is embedded on the front panel. No keys are required; you can set your own password to seal official seals, high-value testing equipment and cultural relic collections. When the latch is locked, it presses tightly against the full-circle rubber sealing strip to block rainwater, dust and humid indoor moisture, so the internal tools and seals stay free from rust and dust accumulation.
Single-side metal support hinge ensures stable opening without damaging the interior: The high-strength rust-proof metal support rod automatically locks the lid once opened, so you do not need to hold it open. You can use both hands freely while sorting seals, calibrating instruments and organizing accessories. The bracket is firmly riveted and will not loosen or fall off even after tens of thousands of opening and closing cycles.
Moderate capacity with lightweight design for portable storage across scenarios: The case balances storage capacity and portability, weighing only 1.4 kilograms. It can hold a full set of official seals, multiple testing probes and all kinds of tiny precision maintenance parts. The flat shape saves space, making it ideal for home desks, outdoor trips and exhibition displays. The rigid aluminum shell offers far better protection than cloth bags and plastic boxes.
Multiple optional liners to meet storage demands across all industries: The basic empty case comes with soft flocking lining that protects instrument screens and metal paint surfaces. The upgraded wave sponge version is fitted with full-coverage high-density slow-rebound wave foam on the lid to clamp small precision parts from top and bottom for anti-shock protection. We also provide customized one-piece molded EVA liners with milled individual slots tailored to the shapes of seals, instruments and accessories, keeping items neatly arranged and preventing shifting during transportation.
Weather-resistant aluminum panel with full customization services: The brushed diamond aluminum panel together with thickened aluminum-magnesium frame resists whitening, embrittlement and cracking under extreme high and low temperatures, and withstands corrosion from alcohol, mild detergents and engine oil. A flat blank area on the front is reserved for logo processing; we can carry out laser engraving and screen printing for corporate logos, store names and equipment serial numbers. For bulk orders, customized case colors, aluminum frame thicknesses and lock styles are available.

Q1: What items are suitable to be stored in this password aluminium case, and what are the daily maintenance precautions?
A: It is ideal for financial official seals, mini testing instruments, precision small repair parts, cultural curios and jewelry, as well as photographic accessories. When carrying the fully loaded case, hold the bottom with both hands to prevent slight deformation of the aluminium frame caused by heavy pressure on one corner. Regularly wipe dust out of the gaps in the password lock to keep it operating smoothly.
Q2: What is the waterproof performance of the case? Can the case be washed with water?
A: The case is only splash-proof and dust-proof for daily use. Do not immerse it in water for a long time or rinse it directly with a high-pressure water gun. Wipe the aluminium surface with a damp cloth when it gets dirty, and dry it thoroughly before storing items.
Q3: How to confirm whether seals and instruments can fit inside the case?
A: Measure the overall length, width and height of the items. They can be fully stored if the dimensions are smaller than the inner compartment size of 330×255×135mm. If the items are oversized, contact customer service for larger-size aluminium protective cases.
Q4: Will the aluminium frame and metal handle be easily damaged when used outdoors in low winter temperatures?
A: Aluminium-magnesium alloy maintains stable toughness under low temperatures, so metal hardware is not prone to brittle cracking. Operate the password lock gently in cold weather to reduce lock wear.
Q5: What is the minimum order quantity for custom integrated EVA lining? Can separate grooving be made for different types of items in different zones?
A: The minimum order quantity for custom moulded lining is 300 pieces. Independent grooves can be made for official seals, testing probes and repair tools respectively, so the whole set of items can be neatly stored in different layers and zones.
Q6: How to clean and maintain the case when it is stained with ink paste or engine oil?
A: Wipe the aluminium panel and the gaps of the aluminium frame with a soft cloth and neutral detergent. Dry all water stains on metal hardware to avoid oxidation. Do not place items into the case until it is completely dry, so as to prevent long-term corrosion of the aluminium-magnesium frame by stains.
