This time, we have started handling new materials. The product name is "KINZO". About this KINZO, we will introduce the properties and uses as a material, as well as the development of new products in combination with our heater products.


Silicon sponge, a new material that can be detected by a metal detector

A new silicone sponge called MDSR (Metal Detecting Silicone Rubber) has been launched. Metal is contained in the silicon sponge, and it has the property of detecting a metal reaction when a metal detector is brought close to it. We sell under the brand name "KINZO".

Please see the next page for product description and technical specifications.

KINZO product introduction

KIN in KINZO is from the word ‘metal (Kinzoku)’, and we named it KINZO with a sense of humanity. You might imagine the talent of Kinzo Sakura, but it has nothing to do with it. Below, we will proceed with the introduction by calling the new material silicon sponge KINZO.

Applicable to packing used in food production lines


KINZO can be used as a packing to connect processed foods to a valve that flows into a container on a production line in a food factory. The material complies with the Food Sanitation Law (Ministry of Health and Welfare Notification No. 370).

 The packing is a consumable item, and the material deteriorates over the years. Therefore, it must be replaced with a new one regularly. If you neglect to replace the packing due to improper maintenance, the silicone sponge may become debris and chip off from the attached valve. Since the debris is small, it cannot be visually confirmed if it enters the container together with the ingredients. As a result, foods containing contamination are shipped without knowing.

 Therefore, if you make the packing with KINZO, you will be able to prevent contamination from entering. Suppose the packing made with KINZO is chipped off and the debris enters the food container. At this time, if a metal detector is installed and operated in the middle of the production line, it will react and sound an alarm when a container containing KINZO debris passes through. After that, if you find the corresponding container, you can eliminatet.

When using KINZO to prevent contamination from entering, metal food containers such as canned foods cannot be used. This is because the metal detector installed on the line will always react. Please keep in mind that it can be used only for containers such as plastic and Styrofoam.

We often see news that more than 10,000 shipped foods have been voluntarily collected due to contamination. When such a situation occurs for the food company of the manufacturer, not only the manufacturing cost and the financial burden of the collection work, but also the credit loss due to food loss and inadequate manufacturing process is immeasurable. KINZO can play a useful role in preventing foreign substances from entering the food manufacturing process.


Sold as a set with a heater processed into the desired shape


So far, we have talked about the use of KINZO alone. Our main product is heaters. Therefore, we are considering product development that combines a heater and KINZO.

 For example, KINZO has the same flexibility and heat insulation as a conventional silicone sponge. Flexible materials allow you to process into complex shapes according to your desire. Therefore, taking advantage of heat resistance, we can manufacture an original heat-insulating jacket-integrated heater made by processing our silicone rubber heater and KINZO into the desired shape.

 When heating from the side using a large heat-resistant plastic container on a production line that requires strict hygiene control such as food, an insulating jacket is used to prevent burns during transport and transfer. At this time, if the insulation jacket is damaged, the small pieces may get mixed in other containers. We believe that a heater with an integrated heat insulating jacket that can solve these problems is significant in development and manufacturing.

 This time, I have described the possibilities of KINZO, focusing on its utilization in the food field. For hygiene-oriented utilization, it can be applied not only to food products but also to products used for skin care such as cosmetics. We will continue to explore the possibilities of KINZO, which we have newly started handling.
