MDO longitudinal stretch testing machine is a special customized equipment to meet various experimental requirements. Generally, processing materials include PET, PP, PE, PVDF, PVC and other special materials. Testing machine can be based on customer requirements with different functions and capabilities.
Gwell stretch testing machine is divided into: sheet testing machine, thick plate testing machine, film testing machine, longitudinal stretch testing machine, coating testing machine, multi-layer composite testing machine, lamination testing machine, reaction extrusion testing machine, mixing testing machine and so on.
The equipment adopts single or multiple extruders co-extrusion technology, equipped with precision distributor, to make product be layered evenly, and each layer can be adjusted ; Horizontal, vertical or oblique plate structure can make the machine easy to operate and maintain; Roller independent power, linear speed and extruder speed can be synchronously controlled; The whole machine adopts PLC control to realize automatic control of parameter setting, data operation, feedback, alarm and other functions. Gwell wrote the control program independently.
