For design and engineering verification

Transform the product development process from engineering prototypes to engineering verification, design verification and production verification.

What is engineering verification

It is a series of components created by combining engineering and design to represent the final product. This powerful and high-precision trial production prototype usually uses rapid prototyping and undergoes rigorous testing and evaluation to verify product design, engineering, and manufacturability.

Choosing the right prototype partner

  • An engineering team with expertise in different manufacturing processes.
  • Use CNC precision machining, rapid machining and injection molding technology to provide test parts similar to end-use products
  • Assist in CAD design review to ensure compliance with predetermined production requirements before prototyping or manufacturing.

Prototype process verification

As product development enters the subsequent stages of the encounter between design and engineering, engineering prototypes and testing can help identify problems.

Identify improvements and iterations before investing in expensive tools and putting them into production to make future production processes as smooth and reliable as possible.

Quality verification

Pass a series of verification test procedures, including basic function test, manufacturing process, performance parameter measurement and certification standard verification.

Can verify whether the design meets the expected product specifications and performance, the goal is to verify whether the design has been correctly implemented into production.

Test in 3 phases of project verification

Verification is a gradual and rigorous process that combines design and engineering development with prototyping and manufacturing. It aims to provide objective and comprehensive testing to meet the expected design requirements, performance, specifications and standards of the product, and to ensure that it can continue to be large-scale Production.



  • The quantity range is 20-50 pieces
  • The material and mechanical properties of the parts must meet the testing requirements
  • Tighter tolerances are needed to verify function in assembly and use.
  • Basic performance testing, including power, thermal and EMI
  • Identify design or process flaws
  • Identify design or process improvement options
  • Perform a second verification after the change

Engineering verification test

Verification function


Verify whether the product meets the functional requirements of the design specification. The EVT version is derived from CNC machining, vacuum casting or rapid machining.



Design verification test

Verify design processability


Design verification is a series of intensive testing procedures used to verify whether a product meets specifications, industry standards and certifications. It also improves tools and processes to achieve consistent production runs, while using pre-production components to meet ideal testing requirements

  • The quantity is usually between 50-200 pieces.
  • All parts should come from the mold or pre-production process.
  • Ensure that the production process meets chemical and environmental requirements.
  • Extensive reliability and compliance testing, including flame retardant, drop, waterproof, battery safety, etc.
  • Verify product certifications and standards in different countries or regions, such as RoHS, CE, FCC, UL, etc.
  • Quick failure analysis and corrective actions are required.
  • Optimize the production plan.

  • The quantity of products often exceeds 500 pieces, which is very suitable for sale.
  • The tool can be started without changes.
  • Mass production verification (yield, time, target cost, rework time, etc.)
  • Design for Assembly (DFA) verification to optimize the assembly process and reduce time and cost.
  • Quality assurance (QA) and quality control (QC) program development and testing.
  • Standard operating procedures (SOP) development and staff training procedures.

Production verification test

Process verification


This is the first trial production, used to identify defects and evaluate optimization at each stage of the production line. The entire production line has been tested to ensure quality.
