Protective box for testing equipment

Testing Equipment Needs More Than Protection Against Drops

Many testing instruments are expensive and highly precise. However, during actual transportation, risks often come from very common situations:
Instruments and accessories colliding with each other inside the box;
Cables, probes, and the main unit being stored in a disorganized way;
Exposure to dust or rain during outdoor testing;
Continuous vibration during vehicle transportation;
Impacts during handling;
Accessories being difficult to return quickly to their proper positions after use.
Therefore, for testing equipment, a suitable protective box should do more than simply provide enough space to hold the equipment.
More importantly, the equipment should remain securely fixed, accessories should be properly organized, tools should be easy to access on site, and the equipment should remain stable after transportation.

Start with the Equipment, Not Just the External Dimensions of the Box

For testing equipment projects, we recommend that customers provide information about their equipment first before selecting a suitable box.
A typical field testing equipment set may include:
Main testing unit
Probes
Power adapter
Test cables
Spare batteries
Calibration accessories
Small tools or documents
If the box is selected only according to the dimensions of the main unit, it is easy to overlook the space required for accessories.
Therefore, when selecting a box, we usually consider the following factors:

For OEM projects, customers can provide equipment photos, dimensions, CAD drawings, or physical samples so that we can further match the internal solution.

Equipment Fixation Matters More Than Simply Using Thick Foam

For testing instruments, effective internal protection is not simply about using thicker foam.
What really matters is:
Whether the equipment can remain securely fixed during transportation.
If the cutout is too large, the equipment may repeatedly move and collide inside the box.
If the cutout is too tight, it may become difficult to remove the equipment.
If the accessories are not arranged in a logical order, users may still need to search for them during field operation.
Therefore, the internal structure should be designed according to the actual equipment.

Available Internal Solutions

1. Pick-and-Pluck Foam.

Suitable for projects where equipment sizes may vary, for small-volume orders, or for customers who want to adjust the internal space themselves.

2. Custom PE Foam

Designed according to the shape of the equipment, making it suitable for fixed models of testing equipment.

3. EVA Insert

Provides a cleaner and more organized appearance, making it suitable for branded equipment sets, instrument kits, and projects with higher presentation requirements.

4. Multi-Layer Foam

Suitable for equipment with a main unit, multiple probes, and many accessories, allowing them to be stored in separate layers.

For Outdoor Testing, Box Sealing Is More Important Than Appearance

Many testing devices are not always used inside laboratories.
Power maintenance, environmental monitoring, telecommunications maintenance, building inspection, outdoor surveying, and equipment commissioning may all require instruments to be taken outdoors.
This means the protective box may need to deal with:
Dust
Sand
Rain
Water splashes
Humidity
Complex ground conditions
WEISHUO protective boxes have SGS IP67 test documentation.
For applicable products and under specified test conditions, IP67 can provide reference protection against dust ingress and temporary water immersion.
It is important to note that:
IP67 does not mean that the box can remain underwater for an unlimited period under all conditions.
If a project involves long-term underwater use, special pressure conditions, or extreme environments, the actual operating conditions need to be evaluated separately.

What Types of Testing Equipment Is It Suitable For?

This type of protective box is not limited to one kind of instrument.
Typical applications include:

If the equipment has a special size or configuration, we recommend confirming the actual dimensions and number of accessories before selecting the box, rather than directly applying a standard solution.

OEM Customization

For equipment manufacturers, instrument brands, and system integrators, WEISHUO can provide different levels of customization according to the actual equipment.
Exterior
Box colour
Logo
Labels
Product identification
Interior
Foam material
Foam thickness
Main equipment slot
Probe slots
Battery and cable areas
Document or instruction manual area

Product Development

Matching existing box models
Internal structure adjustment
Evaluation of new specifications
New mould development
For many projects, it is not always necessary to develop a completely new mould.
If an existing box size is suitable, adapting the equipment through foam and internal layout design is usually a more economical solution.
WEISHUO has customized products for multiple customers, including special colours, logos, labels, and foam solutions. We have our own silk-screen printing tools, which allow us to print customers' logos efficiently in batches. Customers can also select box colours according to colour cards.

WEISHUO's Manufacturing Foundation

WEISHUO did not enter this industry as a "box trading company".
We started with mould design and injection moulding and have accumulated manufacturing experience in the field of precision automotive moulds.
Today, our factory is equipped with various injection moulding machines and mould-processing equipment, supporting the entire process from mould development to mass production.
Our injection moulding machine capacity ranges approximately from:
90T–380T
We are also equipped with Coordinate Measuring Machines (CMMs) and 2D vision measuring equipment for dimensional inspection of moulds and finished products.

The value of these manufacturing capabilities is especially important when customers require more than simply "buying a box".When a project involves structure, dimensions, foam, mould development, or mass production, we can continue the discussion from a manufacturing and engineering perspective.

FAQ

Q1: Can the internal foam be customized according to the dimensions of our testing equipment?
Yes. We recommend providing equipment photos, length, width and height dimensions, an accessory list, or CAD drawings. Based on the equipment layout, we can discuss a suitable internal foam solution.

Q2: We have many equipment accessories. Can they be stored separately?
Yes. The main unit, probes, cables, batteries, adapters, and tools can be designed with separate slots according to the available internal space. Multi-layer foam can also be used when required.

Q3: Can you provide EVA inserts?
Yes. EVA inserts are more suitable for fixed equipment models, complete instrument sets, and projects that require a cleaner and more organized presentation.

Q4: Has the protective box undergone high- and low-temperature testing?
Yes. WEISHUO has SGS high- and low-temperature test documentation, with a test range from -40°C to 80°C.

Q5: What if none of the existing box sizes are suitable?
WEISHUO has mould design and injection moulding capabilities. Based on the equipment dimensions, structural requirements, and expected purchase quantity, we can evaluate the development of a new product or new mould.

Q6: Can we order a sample first?
Yes. For projects with higher equipment-fit requirements, we recommend confirming a sample first before proceeding with mass production.
