Q3: How waterproof is the case, and can it be washed directly with water?

A: The case only provides daily splash-proof and dust-proof performance. It must not be soaked for a long time or rinsed directly with a high-pressure water gun. If the surface gets dirty, wipe it with a damp cloth and neutral detergent, and dry it thoroughly before storing equipment inside.

Q4: How to tell if instruments and tools can fit inside the case?

A: Measure the overall length, width and height of the equipment. It can be fully placed inside if its dimensions are smaller than the internal compartment size of 485×210×215mm. If your equipment is oversized, consult customer service for larger-sized aluminum protective cases.

Q5: Will the aluminum frame and plastic handgrip be easily damaged when used outdoors at low temperatures in winter?

A: The aluminum-magnesium alloy maintains stable toughness at low temperatures, and the ABS panels are blended with cold-resistant modifiers, so they are not prone to brittle cracking under ordinary sub-zero outdoor conditions. Operate the latches gently when opening and closing in cold weather to reduce wear on the hardware.

Q6: What is the minimum order quantity for custom integrated EVA liners, and can separate grooves be cut for different tools in divided zones?

A: The minimum order quantity for liner mold opening is 300 pieces. Independent grooves can be cut simultaneously for testing instruments, sleeves and lenses, enabling neat storage of complete sets of equipment in layered and divided zones.

Q7: How to clean and maintain the case when it is stained with engine oil or cosmetic pigments?

A: Wipe the gaps of the aluminum frame and panels with a soft cloth and neutral detergent, and dry all metal hardware to prevent oxidation from water stains. Store the case only after it is completely dry to avoid long-term residual stains corroding the aluminum-magnesium frame.
