Ningbo Weishuo Molding and Plastic Products Co., Ltd. is a China manufacturer and supplier focusing on industrial protective cases. The company has a modern factory covering more than 7,600 square meters and integrates design, R&D, mold manufacturing, injection molding production, and sales. The impact-Resistant and Shockproof Cases series is used in scenarios where accidental drops, heavy object impacts, and rough handling are common, such as transport, storage, field operations, and emergency rescue.
The product uses 100% virgin high-strength engineering PP plastic without recycled material and offers impact resistance and fatigue endurance. When impacted, the case disperses impact force and reduces the shock experienced by internal equipment. The shock-resistant buffer hard box has multi-layer cushioning and stacking structures, which reduce the risk of equipment damage during transport and handling and lower equipment damage. The case also provides IP67 dust and moisture protection, suitable for equipment with dust and moisture protection requirements.
Impact-Resistant and Shockproof Cases are mainly divided into two series: Fall Resistant and Pressure Resistant Hard Boxes, and Shock-Resistant Buffer Hard Boxes, corresponding to different protection priorities and application needs.
1. This series uses an internal skeleton reinforcement rib structure. When the box falls from height or suffers external impact, localized impact forces are rapidly dispersed throughout the entire structure, preventing stress concentration that could cause rupture.
2. The lid and base feature interlocking stacking structures, maintaining stability and preventing slippage during multi-layer stacking.
1. This series combines load-bearing stacking stability and a multi-layer cushioning system, suitable for equipment transport that must handle vibration, impact, and stacking pressure at the same time.
2. The shock-resistant buffer hard box uses a layered cushioning strategy. The inner layer uses low-density, high-resilience memory foam. The middle layer uses medium-density EVA foam for transitional support, while the outer layer uses high-density foam to form a sturdy frame that resists significant shaking. Overall shock absorption performance more than 40% higher than single-layer foam.
This Impact-Resistant and Shockproof Cases are used in professional fields where equipment must remain intact during transport and handling:
Military: Transporting sensitive communication equipment, targeting systems, and precision measuring instruments.
Broadcasting: Protecting expensive cameras, lenses, and monitors.
Industrial inspection: Carrying precision non-destructive testing equipment and spectrometers.
Emergency rescue: Carrying life detectors and communication equipment.
Physical drop test: Simulates a 2-meter free fall.
Transport slip test: Simulates slipping off a transport vehicle.
Heavy object impact test: Simulates being struck by a heavy object.
Stacking load test: A 20-inch top-load-bearing box is stacked five layers high, with total load exceeding 100 kg. After testing, it maintains its geometric dimensions and normal opening/closing function.
Focus on the Export of Products in the Industrial Protection Field
Since its establishment in 2017, the company has focused on the R&D and manufacturing of industrial protective cases. Products are mainly for export, with stable applications in European and American markets.

Supply Capability from Samples to Bulk Orders
As an integrated manufacturer, the company supports orders from single samples to bulk orders. Our supply chain system and production capacity can handle both small-batch customization and large-scale procurement, suitable for trial production, project procurement, and long-term supply.
Reliable Products Quality
All products use virgin high-strength engineering PP plastic without recycled material. It is impact-resistant and fatigue-resistant and provides IP67 dust and moisture protection. Each impact-resistant hard box undergoes simulation and strict physical testing before finalization.
Customized solutions can be provided based on equipment dimensions, operating environment, and protection requirements, including size, internal cushioning, appearance marking, and functional options, supporting OEM projects.
The case uses precision structural engineering to actively deform and absorb energy upon external impact. Reinforcement ribs, internal skeleton, and multi-layer cushioning system help disperse stress and reduce the impact energy transferred to internal equipment.
The Fall Resistant and Pressure Resistant series uses an internal skeleton reinforcement rib structure to disperse localized impact forces during drops and impacts. The Shock-Resistant Buffer series adds a layered cushioning system and interlocking stacking structures for load bearing and vibration attenuation.
Field testing confirms that a 20-inch top-load-bearing box maintains its geometric dimensions after stacking five layers bearing total load exceeding 100 kg, with normal opening/closing function.
Yes. A stepped flange structure between the lid and body, combined with elastic sealing strips, provides IP67-rated dust and moisture protection.
The case uses 100% virgin high-strength engineering PP plastic and operates from -40°C to 80°C. For higher requirements, reinforced composite options with fiberglass or impact modifiers are available.
