Stocking Programs

Also known as Vendor managed inventory (VMI) programs

Seal & Design is dedicated to helping customers manage inventories in the most cost-effective and efficient manner.

We’re committed to providing the shortest lead times possible, and can turn orders around very quickly when raw material is readily available. With our assistance, you can reduce your stocking costs and increase your inventory turns.

Stocking and Inventory Management Solutions

In addition to prototyping, kitting, and packaging your products, Seal & Design can also store and manage your assets. We help reduce our customers’ inventories and increase their turns with a variety of programs:

  • Dock to stock – our high quality level has allowed a number of our customers to bypass their incoming inspections on our products
  • Last minute and timely deliveries
  • Blanket purchase orders
  • Kanban arrangements
  • Inventory stocking agreements
  • On-line ordering portals customized to meet vendor needs

Kiss Cutting

kiss cutting rotary

Kiss cutting is a die cutting process in which adhesive-backed materials are cut through, but the laminated backing paper is not.

This leaves the kiss cut parts on a continuous roll, dramatically reducing the time it takes for assembly line personnel to handle them. Kiss cuts are a favorite method when production line efficiency is crucial.

Performing kiss cuts is another one of our extensive laminating machine services.

Seal & Design has over 60 years of experience in using machines that make kiss cutting possible, like the Rotary Die Cutting Machine.

EMI/RFI Shielded Rigid Frame Gasket

EMI/RFI Shielded Rigid Frame Gasket

EMI/RFI knitted wire gasketing has been the standard shielding product since its first use in 1944. Since that time, the product has been refined and new knit wire products have been introduced to the present state of the art products.

Rigid Mount Frame EMI/RFI Gaskets consist of an aluminum extrusion with a specially designed jaw. When closed, the jaw crimps the fin of the knit wire EMI gasket to form a rigid construction with the EMI gasket held firmly in place. This extrusion, when fabricated into a frame with the corners of aluminum extrusion mitered and heliarc welded, provided a gasket assembly that can be installed with flat-head screws. This design makes retrofitting int the field a relatively easy task and at the same time provides a positive stop for controlled compression of the EMI Gasket.

Rigid frame gasket is especially recommended for large cabinet doors or access panels that are frequently opened. Knit wire gasketing acts like thousands of tiny spring members which are compressed and released with each opening and closing of a cabinet door or enclosure cover. The spring-lock gaskets assure long life with consistent point-to-point contact, providing high shielding effectiveness and long life.

For applications requiring a moisture seal, an elastomer strip can be bonded to the edge of the extrusion opposite the gasket.

An added barrier to EMI/RFI interference can be achieved by utilizing a double-shielded construction. The double-shielded gasket is recommended for large doors where controlling the mating surface joint unevenness can be difficult and expensive. A further consideration for utilizing the rigid frame approach is the load bearing support of extruded aluminum which aids in applications where shock and vibration are encountered.

Standard knit wire mesh is available in either monel, tin-plated ferrous, or knit mesh with elastomer core of neoprene or silicone sponge.

The highest possible attenuation levels are achievable with EMI/RFI knitted wire gasketing. Attenuation levels beyond 110 dB int eh E-Field and 65 dB in the H-Field are common. Higher levels of attenuation are attainable with special materials and special design. Contact our sales engineers for additional information.

O-Ring Inspection Equipment

In many critical applications (including automotive, aerospace, and life support, among others), 100% dimensional inspection of o-rings is often required. Seal & Design has a host of inspection machines that are dedicated to 100% inspection of o-rings and other seals, to ensure each individual part meets all drawing dimensions and other measurable specifications.

Also called vision systems, these machines use camera stations with either infrared or white light to measure any particular dimension of an o-ring that is deemed to be critical to function. From ID and OD to concentricity and ovality, our equipment measures and sorts parts quickly and efficiently. Seal & Design is home to a variety of inspection equipment, from machines dedicated specifically to o-rings and round parts, to machines that can measure virtually any shape.

Inspection RoomTo prevent any cross-contamination of the 100% inspected parts, bagging machines are attached directly to the inspection equipment. This allows for precise automatic bagging/sealing of parts, with customer required information including part numbers, quantities, and batch information printed directly onto the bags. From start to finish, the time it takes to inspect and bag an o-ring is often less than 10 seconds.

These inspection machines are just another component of Seal & Design’s World Class production facility, which is certified to ISO/TS 16949:2009 as well is ISO 9001:2008.
