The case is constructed with lightweight thickened aluminum alloy frames and a flat matte brushed silver panel, fully wrapped metal anti-collision corner guards on four corners, double-side metal safety locks and double rows of rust-proof rear hinges. It delivers good performance in dust resistance, light water resistance, scratch resistance and mild shock resistance. Three types of inner liners can be freely switched. The square medium inner cavity holds complete sets of small items, solving common problems such as uncategorized messy tools and accessories, bumps of precision instruments during outdoor carrying, lack of dedicated storage for business samples, and difficulty in sorting multi-specification parts. It is a universal multi-functional aluminum alloy storage case for maintenance technicians, inspectors, photographers, beauty practitioners and business clerks.
Lightweight brushed silver aluminum alloy case weighing only 1.5KG for easy portability: It is edged with thickened aerospace aluminum profiles. The matte brushed silver panel is fingerprint-resistant, scratch-resistant and wear-resistant, and the rounded metal corner protectors at four corners cushion the impact from drops. It is lightweight and will not strain your shoulder even if you carry it with one hand for a long trip. It can be directly put into a backpack or briefcase.
Dual-side metal spring snap latches ensure tight closure without loosening: Two symmetrical metal spring latches are fitted on both sides of the case, allowing one-touch opening and closing. The case will not pop open automatically during bumpy transportation or vehicle carrying. The lock body undergoes anti-rust passivation treatment, ensuring smooth opening and closing tens of thousands of times without jamming, and the case can be locked without a key.
Integrated polished curved metal handle resistant to bending under full load: The centrally positioned polished metal handle on the front is reinforced with riveted double-layer metal brackets. When fully loaded with complete sets of tools and samples, stress is evenly distributed. The metal features high toughness so the handle resists deformation and breakage even under heavy loads, and the smooth grip will not dig into your hand.
Three types of inner liners are available to meet storage needs for all scenarios: ① Basic flannel empty compartment: The case lid and inner cavity are fully lined with short black flannel, which is soft and scratch-proof. It is ideal for loose documents, seals and general tools, and stains can be wiped off directly with a damp cloth. ② Double-layer shock-absorbing sponge version: The top lid is fitted with egg-crate wave sponge and the bottom with solid foam. You can manually cut grooves to secure lenses, sensor probes and precision components, providing excellent shock absorption during long-distance transportation. ③ Adjustable compartment with magic tape dividers: Multiple magic tape strips inside allow free combination and partitioning. You can adjust the size of each compartment as needed to classify and store parts and consumables of various sizes.
Double rows of thickened metal rear hinges keep the case lid supported without sagging: Two rows of anti-rust metal hinges are fixed with multiple rivets on the rear side. They boast strong bearing capacity and hold the wide case lid at a stable opening angle. The hinges remain tight without falling off after frequent opening and closing at exhibitions or field work, extending the service life of the case.
Spacious square empty cavity compatible with all custom shock-absorbing liners: The square and flat inner space has no protruding obstacles, making it easy to place complete sets of equipment. It can be fitted with numerically controlled grooved EVA sheets and layered pearl cotton, satisfying both general bulk storage and partitioned protection for precision equipment.
Flexible small-batch customization suitable for multiple industries: The large flat brushed silver panel on the front supports laser engraving and screen printing of logos, equipment models and company names. Custom case colors are available (silver / full black / champagne gold). We can also custom-make exclusive grooved EVA liners according to the dimensions of instruments and parts.

Q1: Will internal precision instruments be damaged if this lightweight aluminum case is dropped?
A: The metal corner protectors on four corners can absorb impacts from minor everyday drops. If you store high-precision items such as lenses and sensors, we recommend choosing the double-layer shock-absorbing sponge liner for better anti-shock protection. The case is not suitable for heavy drops from high altitudes.
Q2: Can the case be cleaned with water?
A: Wipe the aluminum alloy frame and brushed silver panel with a damp cloth; do not soak them in water for an extended period. Keep flannel fabric, sponge and compartment dividers away from water. Air-dry the case thoroughly before storing items after cleaning.
Q3: Can a complete set of small tools and instruments fit fully inside?
A: Items with overall length, width and height smaller than the internal dimension of 365×265×125mm can be fully stored. For larger equipment, please inquire about the enlarged aluminum protective case of the same series.
Q4: Can damaged accessories including latches, handles, hinges and corner protectors be replaced separately?
A: Latches, metal handles, anti-collision corner protectors and hinges are all standard universal parts. We can send individual replacements for self-installation once you provide the case model number.
