Crayons and inspection markers are ideal for industrial applications in the tire, rubber, hose, automotive, and other OEM industries. The products have low VOCs and are typically used for inspection and identification purposes.
The fugitive crayons, also referred to as ply markers, are safe for internal use on uncured rubber surfaces such as calendared material, plies, bead rings, etc. When used in production, fugitive crayons do not act as contaminants and will not cause delamination. The product is available in a variety of colors.
Dot Markers are typically used in tire manufacturing to denote high point, conicity, and pass/fail marks. The dots help to ensure synchronization of the tires during the rim assembly process and when mounting a tire.
APV’s tire writers are water-based and can be removed easily with water. This product is used to mark cured tires or rubber goods for inspection and identification purposes in the manufacturing process.
The UV marking crayon (C-0303) is specifically designed to mark a rubber surface with visibility under UV identification and inspection cameras. The product is compatible with uncured rubber surfaces and is not visible after curing. This crayon fluoresces under 365 nm ultraviolet light. It is a valuable tool for identification and quality control procedures in rubber manufacturing.
The disappearing crayon (C-0300) is specifically designed to visibly mark uncured rubber surfaces to denote problem areas or identify material in a production process. The mark disappears from the surface or becomes no longer visible once the rubber part has been cured. Disappearing crayons are also a valuable tool for identification and quality control procedures in rubber manufacturing.
