  FORMEX  INSULATOR  SHEET           

What is Formex?

FORMEX is flame retardant grades of polypropylene, extruded into sheet and primarily used for their electrical insulation properties. These materials meet the insulation requirements for most applications due to their high dielectric strength (1460 V/mil @ 17 mil thick), low moisture absorption (<0.1%) and UL 94V-0 flame class rating. Polypropylene provides exceptional scoring and bending characteristics resulting in superior folded parts.

Key Features:1, UL 94V-0 Grade flamdant2, Extremely low water-absorption, nearly0.06% 3, High voltage resistant, even 24820V.4, Excellent resistance for stetching and folding5, Excellent sticking and falling resistance in prittin6, Conform to ROHS, CSA,ICE,UDE,BSR

Introduction of Die cutting

Die cutting is the transfer of pressure through hardened steel dies to softer material in order to cut, score or crease the material into desired shapes or patterns. The steel rule die is the most common due to its versatility. Steel rule dies can be used on most presses, can be hand-placed or platen-mounted and are the most economical.

A steel rule die consists of a hardwood base with sharpened steel blades, or rule inserted and connected in a pattern. Different techniques of assembling the punches, blades, ejection, and other die components may be used to accommodate the various characteristics required for each part. Designs which take into consideration the strengths and weaknesses of this die system produce failure-free parts economically.

Steel rule serves two functions; to cut material completely through or to score the material for folding. Center and side bevel rule is used for full or partial cutting. Creasing rule is used to provide a score line without cutting material. The perforating rule is used for "perf" scoring, which is preferred in certain applications. Die construction details are usually specified by the die maker and the part fabricator. Multiple cavity dies are available for higher volume production.

Die cut parts have four basic elements: blanks, scores, holes and tabs. These features can usually be formed simultaneously.
