대화정밀공업은 최고 품질의 자재를 생산하기 위해 노력합니다.: Packer

: Description

Packer is a must have in chemical grout used for injection of epoxy and polyurethane foam in into hose penetrated at a pressure higher than 20kg/cm(max. pressure 500kg/ch) on to concrete structures. We produce the injection packers in various specifications that are required in repairing and reinforcing concrete structures.

The factory automation we have enable us not only cut back costs but also produce them in uniform quality. The specification of packers used here may be chosen depending on the thickness of the concrete structures and on site situations.

Advantages of packer

- It is possible to force a large amount of resin at a high speed, which ensures the through injection.
- Because backwater check valves are installed on bolt areas, it is possible, irrespective of the hardening of resin, to snap the severed parts of the nuts immediately after the injection work is completed.
