AMETEK STC (Sensors, Test&Calibration) is a manufacturer of testing and calibration instruments and process instruments, headquartered in the United States. AMETEK STC has three major series and 15 global brands, committed to providing accurate, reliable, and rich testing, measurement, and calibration solutions for our customers.

LLOYD Instruments is a world-renowned manufacturer of innovative material testing systems, offering customers a wide range of machine models to choose from, suitable for testing the physical and mechanical properties of any material, component, or product. Suitable for finished product testing, such as plastics, packaging materials, medical equipment, electronic components, textiles, metals, composite materials, paper, and others. Lloyd Instruments provides professional material testing solutions for all types of applications. As part of Ametec Corporation, Lloyd Instruments has business and technical branches in over 80 countries.

In order to improve the scope of our material testing system, LLOYD also provides complete solutions for polymer and plastic testing applications, completing testing from raw materials to finished products through the DAVENPORT series of products. DAVENPORT was a subsidiary of ICI, a former British company, which was successfully acquired by LLOYD in 1992. ）LLOYD provides professional material testing solutions for all types of applications.

LLOYD provides professional material testing solutions for all types of applications. The scope of the experiment includes:

Tensile strength and compression
Friction coefficient of flexural/flexural strength
Breakdown strength and tensile strength
Peel strength and shear strength
Layered strength, bonding strength
Adhesive strength, fracture load
Creep and stress relaxation compressive flatness
Deformation strength and ductility
Elastic ultimate elongation
Fracture strength Young's modulus
Resilient torsion

Our DAVENPORT polymer tester's established range has been established in many testing standards, allowing for the measurement of important polymer parameters including melt index, melt flow rate, melt volume flow rate, and melt density/viscosity, as well as the intrinsic viscosity and melt viscosity of PET, impact strength of plastic film, density measurement, thermal deformation and Vicat, and friction coefficient measurement.
