  • VOC Test
  • Mechanical Property Test
  • Dimension Test
  • Water Taste Test
  • VOC Test

    VOC test will be conducted for food-grade product in EU market or other required markets. The purpose of this test is to ensure that the materials used in the production are free of harmful or toxic substances.

    Including tensile strength, tearing strength, compression set, hardness and other aspects of testing. Through these tests, we can effectively prevent unqualified raw materials from flowing into the production.

    • Control of physical properties in raw materials
    • Determining the service life of the product
    • Checking the product functionality
  • Dimension Test

    We use a precision optical projector and a depth gauge in the laboratory to measure the size of our products, the accuracy is less than 2 microns. For some dimensional demanding projects, DX will have IPQC for dimension.

    • High accuracy
    • Lab testing
  • Water Taste Test

    Products like the silicone parts that are used in household appliances such as water dispensers, coffee machines, etc., need to pass this test. This test ensures that water or fluid pass through silicone parts would be free of odor.
