CRANDALL INTERNATIONAL offers manual and inline cap sealing systems for low or high speed cap sealing applications, to line speed of 50 meters (150 ft.) per minute .
Induction sealing is a non-contact process which bonds a foil disk or "seal" to the opening of a container. It can be used for most types of containers and can be used for foods, drugs, chemicals or petroleum products.
The inner seals meet the requirements of the FDA and can be used on containers of all compositions.
Induction sealing will provide the user with a tamper evident seal to assure product integrity and prevent leakage. This will increase the products shelf life, reduce pilferage, and increase customer confidence in your product.
The machines are portable and able to be used in multiple locations.
The solid state circuitry provides high control of the
sealing process.
Up to 30 caps/minute may be sealed on hand held units. Inline machines can seal containers on a conveyor at up to 45 meters/min.
Caps with diameters from 5 mm to 120 mm may be sealed.
No tools are required for adjustment or set-up. Sealers require no maintenance and are air cooled, requiring no water for cooling.
It is silent and has no discharge.
Containers are filled and capped by the normal process. The caps used are specially lined with an induction inner seal which is provided by the manufacturer of the cap.
The cap passes through an electromagnetic field generated by a hand held sealing head, or passes below a high volume sealing head on a conveyor.
The electromagnetic filed induces a strong electrical current in the foil of the seal which causes the foil in the seal to heat. When the foil is heated, it fuses to the lip of the container. When the container leaves the electromagnetic field, the foil cools.
