[Case Study on Production Equipment] Gasket Replacement Work

Special gasket damaged? We can produce it urgently! We also carry out replacement work to contribute to the early restoration of the production line.

In a case at a pharmaceutical company, a filter-integrated gasket incorporated into a rubber-lined tank was damaged, causing expensive resin material to leak outside the tank, which required urgent response. Considering the dissatisfaction with the airtightness, we proposed a review of the structure and a redesign for production. As a result, we were able to complete the replacement work for the affected tower in about a month after the consultation. Not only did we shorten the delivery time, but our safety management system for the construction was also appreciated, leading to the request for the replacement work of all remaining towers. [Case Study] ■ Issues - The filter had a tear, causing expensive resin material to continue leaking outside the tank, resulting in daily losses. ■ Proposal - Considering the dissatisfaction with the airtightness, we reviewed the structure and proposed a redesign for production. *For more details, please refer to the PDF document or feel free to contact us.

Conductive silicone gasket for noise reduction: "Ultra Ban Shield"

The two-layer structure significantly improves followability and adhesion! It exhibits excellent conductivity even under low compression.

The "Ultra Band Shield" is a conductive silicone designed for noise reduction (a two-layer extruded product of conductive silicone and silicone). By integrally molding a conductive layer (jacket part) and a high-tensile silicone layer (core part) into a hollow shape, it achieves high conductivity, compliance, and adhesion. We also offer a waterproof type that integrates waterproofing and noise reduction. 【Features】 - The elastic core layer does not contain conductive materials, preserving the mechanical properties of silicone and making it resistant to aging. - The jacket part filled with conductive materials provides excellent conductivity. - Being silicone, it has very low compression set and is resistant to deformation. - Achieves waterproofing and noise reduction in a single product. *For more details, please refer to the PDF materials or feel free to contact us. *Product sample sets are currently available! Please apply through the contact form.

The enclosure equipped with waterproof and conductive gaskets has passed the waterproof test (IPX7).

The enclosure, using the two-layer silicone gasket "Ultra Band Shield," has passed the IPX7 waterproof test.

IPX7 refers to a grade of waterproof performance for electronic devices as specified by Japanese Industrial Standards, indicating "immersion-proof" that can temporarily withstand submersion under specific conditions without water ingress or adverse effects on the device. A housing using the two-layer structure gasket 'Ultra Ban Shield(R)', which has a highly conductive conductive layer and a non-conductive core layer, has passed tests under the following conditions, proving its waterproof capability. ■ Standard: IEC 60529 IPX7 ・ Test Equipment: Immersion Tank ・ Water Depth: 1m (top edge at least 0.15m above) ・ Test Duration: 30 minutes ■ Housing Dimensions: W100×H70×D4mm, Weight: 250g ■ Product Name: UV DD20-19J-03 【Result】 No water ingress under the above conditions. *If you wish to view the test report, please contact us. *Product sample sets are currently being offered! Please apply through the contact form.
