Laboratory & Testing Capability

At WJM, we believe that reliable products are verified by data, not by assumptions. To ensure the performance, durability, safety, and consistency of our silicone and plastic products, we have established a well-equipped in-house laboratory and testing center.

Our laboratory is capable of conducting dimensional inspection, mechanical performance testing, environmental reliability testing, wear resistance testing, aging tests, and appearance evaluation, covering the entire lifecycle of product development — from R&D verification, engineering validation, to mass production quality control.

With these testing capabilities, we help our customers:

• Verify product design reliability

• Reduce project risks before mass production

• Ensure long-term product stability and durability

• Meet different market and application requirements

1. Dimensional & Structural Measurement

Optical Measuring Machine (2D Measuring System)

We use high-precision optical measuring machines (2D measurement system) to:

• Measure critical dimensions of silicone and plastic parts

• Check profile, hole position, thickness, and tolerance

• Verify consistency between drawings, samples, and mass production parts

This ensures that all key functional dimensions meet design specifications, especially for precision parts and assembly-related components.

2. Mechanical & Functional Performance Testing

Curve Tester

The curve testing machine is used to:

• Test force-displacement curves

• Measure compression force, rebound force, insertion force, and pull-out force

• Verify the mechanical behavior of silicone and plastic parts during actual use

This is especially important for:

• Buttons, seals, flexible parts, elastic components, and structural parts

Life Cycle & Continuity Tester

The life and continuity testing machine is used to:

• Simulate repeated use conditions

• Test product durability, electrical continuity (if applicable), and mechanical life

• Verify whether products maintain stable performance after tens of thousands or even millions of cycles

This ensures that products meet long-term reliability requirements in real applications.

Multi-Function Friction & Abrasion Tester

This equipment is used to:

• Test surface wear resistance

• Evaluate coating durability, printing durability, and surface treatment quality

• Simulate repeated friction during daily use

It helps us ensure that:

• Logos do not fade easily

• Coatings do not peel off

• Surface appearance remains acceptable after long-term use

Tape Adhesion Tester

The tape test machine is mainly used to:

• Evaluate adhesion of coatings, printing, and surface treatments

• Check bonding strength between coating and substrate

• Verify whether surface treatments meet adhesion standards

This is critical for painted parts, printed logos, UV coatings, and sprayed surfaces.

3. Impact & Drop Testing

Drop & Impact Testing Machine

This equipment is used to:

• Simulate product drops during transportation and daily use

• Test impact resistance and structural integrity

• Evaluate whether products crack, break, deform, or lose function after impact

It is especially important for:

• Consumer electronics accessories

• Protective cases

• Structural and housing parts

4. Environmental Reliability Testing

Programmable Temperature & Humidity Chamber

This chamber is used to:

• Perform high-temperature, low-temperature, and high-humidity tests

• Simulate extreme environmental conditions

• Verify material stability, deformation, aging, and performance changes

This ensures that products can work reliably in different climates and application environments.

Precision Salt Spray Testing Chamber

The salt spray test machine is used to:

• Test corrosion resistance of metal parts and coated components

• Evaluate surface treatment durability

• Verify resistance to oxidation and corrosion in harsh environments

This is especially useful for:

• Products used in coastal, humid, or industrial environments

• Parts with metal inserts, coatings, or surface treatments

UV Accelerated Weathering Tester

This equipment is used to:

• Simulate long-term exposure to sunlight and UV radiation

• Test material aging, discoloration, brittleness, and performance degradation

• Evaluate long-term outdoor durability

It is critical for:

• Outdoor products

• Automotive-related parts

• Products exposed to sunlight for long periods

5. Color & Appearance Control

Colorimeter

The colorimeter is used to:

• Measure color values accurately

• Control color consistency between samples, batches, and mass production

• Avoid visible color deviation issues

This is extremely important for:

• Brand products

• Appearance parts

• Multi-batch long-term supply projects

6. Prototyping & R&D Support

3D Printer

Our in-house 3D printing capability is used to:

• Rapidly produce prototypes for structure verification

• Support R&D and engineering evaluation

• Speed up project development and reduce early-stage risks

This allows us to verify product structure and assembly before tooling investment.

7. Why Our Laboratory Matters

With this complete testing capability, WJM can:

• Detect potential risks before mass production

• Verify product reliability through data and testing

• Reduce customer quality concerns and project risks

• Provide more stable, predictable, and controllable quality output

Our laboratory is not only a testing center, but also a core part of our engineering and quality assurance system.
