The Professional Choice for Vibration Protection WEISHUO's Built in shockproof sponge hard boxes are designed specifically for precision equipment requiring extreme vibration protection. During instrument transportation, field operations, and daily storage, vibration is one of the main causes of equipment damage and decreased accuracy. Traditional protective cases only provide basic impact protection and are insufficient to effectively isolate high-frequency vibrations and continuous impacts. Our products, by integrating professional-grade shock-absorbing foam liner, add active shock absorption on top of IP67 sealing protection, providing comprehensive protection for your precision instruments, electronic equipment, optical instruments, and other sensitive equipment.

Correct Usage: Place the equipment in the customized foam box according to its shape; ensure the equipment and foam are completely fitted together, with no gaps. Place heavier equipment on the lower foam layer; check that no objects are pressing on the sealing strip before closing.
Sponge Maintenance
Daily Cleaning: Wipe with a soft cloth; avoid using organic solvents.
Regular Inspection: Check the sponge's elasticity recovery monthly.
Deep Cleaning: Disassemble and clean quarterly; allow to air dry.
Lifespan Assessment: Replace if the recovery time after compression is >5 seconds.
Sponge Replacement Service: Standard sponges have a lifespan of 3-5 years (depending on usage intensity); original factory sponge replacement service is provided.
Old sponge recycling is supported; replacement cycle recommendation: evaluation every 3 years.
Q1: Will shock-absorbing sponges age and harden? What is their lifespan?
A1: Under normal use conditions, the performance degradation of high-quality polyurethane sponges is <15% within 3-5 years. It is recommended to check every 3 years and decide whether to replace them based on usage intensity.
Q2: What should I do if the sponge gets damp?
A2: Our sponges are hydrophobic; slightly damp sponges can be air-dried naturally. If severely soaked, it is recommended to disassemble and thoroughly dry them, and replace them if necessary. An antibacterial version is available to prevent mold growth.
Q3: How to customize sponges for irregularly shaped equipment?
A3: Please provide the actual equipment or precise 3D drawings. Our engineers will design the optimal cutting plan to ensure that every protruding part of the equipment is protected.
Q4: How to verify the shock absorption effect of the sponge?
A4: We offer three verification methods: 1) Simple test: Drop test with a raw egg placed inside the box; 2) Professional test: Measuring the transmission rate using a vibration tester; 3) Actual verification: Testing the accuracy after actual transportation of the equipment.
Q5: Minimum order quantity and customization period?
A5: Minimum order quantity for standard liner models is 20 pieces, and minimum order quantity for customized sponge liners is 50 pieces. Customization period: Delivery within 15-20 working days after sample confirmation.
