Pierced Metal Products

In addition to perforating, Diamond manufactures two types of pierced metal products, both of which are patented: PLASTICORE™, a single-sided piercing and GASKETCORE™, a double-sided piercing. Generally, these products are used in conjunction with customer-applied materials to provide strength and stability to the finished units.

GASKETCORE™ or PLASTICORE™ can be supplied in sheet, coil, or part form to best suit your manufacturing process. To discuss potential applications, request a quote, place an order, or receive a sample of either material type, contact our Customer Service Department.

PLASTICORE™

A single-sided pierced metal product that provides additional strength and heat resistance to molded plastic parts. When placed in a mold with its tangs facing upward, plastic injected into it seeps through the openings and forms around the tangs - creating plastic flanges or "buttons". A cross section of a piece is shown above.

Developed for use in heat shields, PLASTICORE™ protects and strengthens plastic and composite materials. Embedded within the material while it is in a molten state, PLASTICORE™ can enable parts to withstand greater amounts of stress. In fact, parts that have been made with PLASTICORE™ yield excellent results in gravelometer tests.

PLASTICORE™ is available in rust preventive .004" and if volume warrants .006" thick stainless steel type 304 with a maximum width of 39.4". It can also be produced in either .006" - .012" thick carbon steel or aluminum with a maximum width of 24".

GASKETCORE™

A double-sided pierced metal product that is an environmentally friendly alternative to toxic adhesives commonly found in the center of gaskets. It replaces the use of adhesives by virtue of the tangs that attach the metal to gasket material when activated under pressure.

Developed for use in gaskets, GASKETCORE™ grips to gaskets and other soft materials when pressed together. It uses specially designed tangs that penetrate the material's outer surface and fold back on the base material, thus creating a secure grip. GASKETCORE™ is available in single- or double-sided material and is typically applied under the force of calendar rolls.

GASKETCORE™ is available in rust preventive .004" thick stainless steel type 304 with a maximum width of 39.4". It can also be produced in .006" - .012" thick carbon steel with a maximum width of 24".
