Elenets is committed to providing high-quality, environmental-friendly heat shrink productions, therefore all of our products are manufactured in compliance with ISO 9001 quality standard in our advanced and well-equipped production facilities.
Elenets stringently controls and monitors every stage of the manufacturing process, from the selection of raw materials through extrusion & molding, E-beam cross-linking, expansion, to adhesive coating, and color formulation.
Our manufacturing facilities utilize Advanced Process Control system to monitor and control the production lines operations in real-time.
MATERIAL SELECTION AND EXTRUSION
Elenets carefully selects the raw thermoplastics materials, such as polyolefin, PTFE, fluoropolymer, PVC, silicone elastomer or Viton. In the first stage, the raw materials and additives are analyzed for consistency of physical properties and quality, then cleaned and blended into an internal mixer to pelleting.
The prilled granules are extruded into the designed sizes. The process is fully automated and controlled by APC system to ensure the tubing dimensions and qualities.
The next stage is the cross-linking process with Electron beam (E-beam) system. The cross-linking technology could significantly improve the maximum operating temperature of the products, and keep Consistent memory characteristics. By controlling the process, Elenets aims to improve resistance to chemical, abrasion and mechanical impacts, while reducing creep effect.
The following process after cross-link is heating and expansion. The tubing is heated just above the polymer’s crystalline melting point and aid stretching (expansion) of the tubing applied. In this process, the diameter of the tubing is increased by outside vacuum at a temperature slightly above the crystalline melting point of the polymer used. Rapid cool-down follows the process. The tubing is cooled down far below its crystalline melting point and thus reaches a state in which a high amount of radial stretch is incorporated in the tubing. It is during this part of the process that the shrink ratio and shape memory characteristics are determined.
EXCELLENT LEVEL OF QUALITY
With a high level of advanced automation technologies used in all processes, the majority of personnel of each process concentrate on stringent control and monitoring of quality. This ensures that all performance aspects of the tubing are consistently maintained with the combination of Elenets expertise in the manufacturing processes.
