Testing Equipment

The quality of finished leather relies much on quality control in its manufacturing process. That is why we set various quality check points along the production line to keep close track of quality. We also set out high standards against which all our leather materials are checked to ensure the finished leather will be accepted by customers from around the world. A specialized quality inspection team continuously inspects our leather against internal and customer requirements.

For us, quality is a critical part of the supply chain, whether it is quality checks before raw materials enter the production line, quality inspections during the manufacturing process, or checking quality before finished leather arrive at the customer.

Prior to Manufacturing
Each batch of raw material is closely checked before entering into the production line. At this stage, our inspection team takes the responsibility for running tests on all the chemicals, polymer resin, plasticizers, colors, and cloth that will be used in the manufacture of leather according to our internal regulations. Test reports would be stored. Advanced equipment is used to perform these tests, which can be seen in the following pictures.

  • Single-strand yarn strength tester --- used to test the strength of a single strand of yarn

  • Differential scanning calorimetry and thermo-mechanical analysis instrument--- used to test the degree of fiber crimp
  • High-power microscope---used to observe the cross-sectional shape of the fiber

  • Moisture analyzer--- that relies on the pressure difference to measure the water content in the raw material.

During Manufacturing
In the manufacture of leather, care is taken to produce qualified products that not only meet customer specific requirements but also achieve our internal standards. During the filament weaving and drying process, the material’s viscosity is an important factor to consider. After a series of checks, the knitted fabric is then laminated to the required leather and obtains desired grain patterns.

  • Reciprocating water bath shakers + Kinematic viscosity tester – that measures the viscosity of raw material
  • Melt flow rate meter - used to measure the melt flow rate

  • Pilot Production Line for Filaments –
    that mixes polyamide and polyethylene to produce filaments.
  • Dry-type Pilot Production Line – that laminates leather to the semi-finished fabric and produces desired grain patterns.

Final Inspection
Before finished leather leaves factory, its physical properties and dimensions are measured. Only qualified products are allowed to be delivered.

  • Electronic universal testing machine – used to measure the tensile strength, peel strength, and percent elongation of leather
  • Water vapor permeability tester – that measures the breathability of leather

  • High performance liquid chromatograph – that measures the environmental performance of leather, such as testing its 6P.
  • Fabric strength tester – that measures elastic modulus, tensile strength, and other physical properties
  • UV-1800 Ultraviolet–visible spectroscopy instrument
  • Gas chromatography instrument

  • Laboratory 1
  • Laboratory 2
  • Testing center
