Stretching mold

Tensile dies are mechanical devices used to conduct tensile testing, often used in materials testing and engineering applications to evaluate the mechanical properties, strength and deformation behavior of materials. Tensile testing is an important material testing method that measures the tensile properties of a material by applying tension in a vertical direction to a standardized specimen (usually a specimen with a circular or rectangular cross-section).

Here are some key features and uses of stretch dies:

Test material properties: Tensile molds are used to measure performance parameters such as tensile strength, yield strength, breaking strength, elongation and elastic modulus of materials. This data has important implications for material selection and design.

Standardized testing: Tensile testing is a standardized testing method that usually follows international standards to ensure the comparability of test results. Different types of materials (metals, plastics, rubber, etc.) often require different types of tensile dies and testing procedures.

Tensile Machine: Tensile testing often requires the use of specialized tensile machines or materials testing machines that have the ability to apply controlled force and record deformation.

Sample Preparation: Tensile dies typically include clamps and templates used to prepare and clamp standardized tensile specimens.

Material failure: Tensile testing often results in fracture of the material, providing information about the material's strength and toughness.

Engineering applications: Tensile molds are not only used in materials testing laboratories but are also widely used in engineering design and quality control to ensure that product materials perform as expected.

Materials Research: Tensile testing can be used to study the behavior of materials, such as their plastic behavior, fracture modes, and stress-strain curves.

Drawing die design and specifications depend on the specific application and material type. As needed, they may come in different shapes, sizes and fixture configurations to accommodate different testing standards and material properties.
