Ishida and Sealing System
Control weighing of packaged products
A checkweigher is a machine used to check i.a. that the package contains the right number of items and products, and that the weight is correct.
Generally, food product declarations have to state a specific amount of content, expressed as a weight, volume, or number of items. The checkweigher checks the weight of a packaged product to ensure that it holds the correct amount of content. In order for the product to pass the checkweighing step, it must be contained in a closed/sealed packaging, which prevents subsequent addition or removal of products. The solution is intended to secure that the package as a minimum contains the amount specified in the declaration.

Accurate checkweighing for high-capacity set-ups
Ishida's checkweighers are among the best products on the market. Ishida's checkweighers are designed to run accurately at high capacity.
Ishida also manufactures multihead weighers for weighing products, and a checkweigher is often installed downstream from these. The checkweigher can also be supplied as a stand-alone unit with a metal detector and/or an X-ray scanner and a common reject system.

Ishida is a Japanese family-owned company, founded in 1893, which employs a staff of some 3,600. Ishida is a world leader in production of multihead weighers, quality control (seal testers, x-ray scanners, check weighers) and snackfood bagging machines.
Sealing System has been a reseller of Ishida's sophisticated automatic equipment since 1995. The solutions are sold either as stand-alone machines or as components for integration in complete packing lines. Ishida has installed 50,000 multihead weighers globally.
Ishida is co-operating with a host of international groups and always meets the most rigorous standards. Ishida has taken out a huge number of patents related to the multihead weigher, so in actual fact it is not possible to manufacture a multihead weigher without using technology patented by Ishida.
We know of several Ishida units which are still working at full production capacity even though they are more than 30 years old.
