Medium Low-profile Precision Instrument Protection Case

Product Introduction

This low-profile rigid plastic safety protective case is specially designed for precision testing instruments, electronic equipment, photographic gear and small experimental devices. Its external dimensions are 425×355×105mm, internal dimensions 410×320×96mm, and the net weight of the case body is 1.8KG. Manufactured via one-piece injection molding with modified high-strength PP engineering plastic, it is equipped with an integrated IP67 sealing rubber ring, double-safety latches and an air pressure balance valve structure to deliver multi-layer protection against water, dust, shock and compression. Users may optionally equip the case with tearable foam or CNC one-piece molded EVA liners, which can be grooved to fit the shape of equipment and secure it firmly to eliminate shaking and collision risks during transportation. Featuring a slim, low-profile design, the case fits various scenarios including office use, business trips, field inspection and vehicle storage. It addresses pain points such as moisture exposure, collision damage and breakage of precision equipment, making it an essential safety storage solution for laboratories, testing institutions and photography studios.

Core Selling Points

IP67 grade sealed protection to block erosion from moisture and dust.An integrated high-elastic rubber sealing ring is embedded at the box opening for a tight and seamless closure. It can resist splashing water, dust and mist intrusion, enabling reliable use in high-humidity and high-dust environments such as outdoor areas in rainy weather, construction sites and coastal regions. The equipment is less prone to dampness-induced short circuits, and the lens is protected against dust ingress and scratches.

Integrally injection-molded reinforced rib structure, low-profile body with drop and pressure resistanceThe entire enclosure features integrally formed surrounding protruding reinforcing ribs. While adopting a slim and low-profile design, it delivers outstanding impact resistance. It resists cracking and denting when dropped from heights or squeezed under stacked heavy loads, and protects internal equipment from damage during rough courier sorting and bumpy vehicle transportation.

Comes with a built-in pressure balance valve for smooth case opening at all altitudes.The integrated waterproof pressure relief valve automatically equalizes the air pressure inside and outside the case. It eliminates the issue of negative pressure locking the lid shut under air transport or high-altitude temperature differences, enabling hassle-free unpacking during cross-regional transportation.

Low-profile and slim design, suitable for multiple scenarios including office work, business trips and field operation.Its slim body saves space and can be easily put into briefcases, equipment cabinets and car trunks. With a net weight of 1.8KG and an embedded ergonomic handle, it can be carried effortlessly with one hand, making it convenient for business trips and field work.

Double buckles with lock holes for safer storage and transportation.The bilateral self-locking spring buckles fasten tightly and will not pop open accidentally during transit. Lock holes are reserved on the buckles, allowing padlocks to be fitted for outdoor storage and logistics delivery to secure precision equipment.

Self-locking Double Spring Buckle

The thickened engineering plastic buckle delivers strong and even fastening force for a secure fit, so it won’t loosen during bumpy transportation. A reserved lock hole allows installation of anti-theft padlocks for safer equipment storage.

Independent Waterproof Pressure Relief Valve

The valve comes with an integrated waterproof structure that will not compromise the sealing performance of the cabinet. It automatically balances internal and external air pressure, enabling effortless cabinet opening during air transportation or in high-altitude areas.

Reinforced Integrated Handle
Multi-point rivet fastening ensures even force distribution, preventing breakage or deformation even under full load. The ergonomic grip curve fits the palm comfortably, reducing fatigue during prolonged carrying.

Organize the interior space of the general warehouse

Smooth inner compartment without partitions delivers high space utilization. Multiple small instruments, supporting cables and probe accessories can be neatly stored side by side, compatible with equipment storage of various sizes.

Material and Process Description

Main material of the cabinet body: High-toughness modified PP engineering plastic, added with impact-resistant, cold-resistant and anti-aging additives. It features excellent toughness and resistance to cracking, and can withstand mild acid and alkali corrosion.

Sealing rubber ring: Made of highly elastic natural rubber, it maintains lasting resilience without hardening, and will not crack or fail after years of service to consistently guarantee sealing performance.

Metal connecting parts: Metal fittings including hinges and lock holes are electroplated for rust prevention, so they are not prone to rust or jamming in seaside and high-humidity working environments.

Forming process: Integral high-pressure injection molding without splicing gaps. The cabinet boasts strong structural integrity with no risk of water seepage or cracking at splicing joints.

Assembly process: Mechanical fastening assembly with buckles, pressure relief valves and hinges. All fixing points are reinforced with riveting to avoid loosening or shifting during long-term use, and the rubber ring is precisely embedded to prevent falling off.

Liner processing: EVA foam is integrally cut by numerical control for accurate clamping that fits the equipment contour perfectly. Tearable foam layers are independent, allowing repeated adjustment of groove layouts to fit various types of instruments.

FAQ

Q1: Can this case be submerged in water for a long time?

A: This product has an IP67 protection rating. It will not let water in when exposed to splashes for a short time or shallow immersion, making it suitable for outdoor use on rainy days. However, it cannot withstand prolonged continuous deep-water submersion.

Q2: Can a padlock be fitted onto the latch?

A: The latch is pre-drilled with a standard lock hole. You may install a small padlock on it as needed, offering better anti-theft security for outdoor storage and logistics delivery.

Q3: Can the pressure relief valve be removed and left unused?

A: Removal is not recommended. The pressure relief valve balances the air pressure inside and outside the case. It prevents negative pressure from suction-locking the lid shut during air transportation or high-altitude use, and comes fully installed from the factory.

Q4: Can the foam insert be replaced separately after wear and tear over time?

A: Empty cases and inserts are sold separately. A replacement foam insert can be shipped individually once the original one ages or wears out, with no need to replace the entire case.

Q5: Will the case harden and become brittle under low temperatures in northern winters?

A: The case is made of cold-resistant modified PP material. It maintains toughness even at temperatures as low as -30°C, and can function normally for outdoor winter operations without cracking upon impact.

Q6: Will instruments shift and rattle around when placed inside an empty case?

A: An empty case only holds loose accessories and cannot secure equipment. We recommend pairing it with custom milled EVA foam, which features cutouts shaped to match your instruments to eliminate shifting and abrasive scratches entirely.
