CCSi UltraLife molds are designed, engineered, and manufactured to produce high quality specimens, over an extended service life!
CCSi manufactures these specimen molds for the determination of the abrasion resistance of vulcanized (thermoset) rubbers, thermoplastic elastomers, elastomeric and similar materials to a standardized reference system, as described in ASTM D2228 “Standard Test Method for Rubber Property-Relative Abrasion Resistance by the Pico Abrader Method.”
A standardized set of reference compounds is used to calculate the relative abrasion resistance. These reference compounds are also used to determine the relative performance, within a permissible range, of the cutting knives used in performing the test.
CCSi is also a source for new Pico cutting knives, as well as re-sharpening of worn blades. All new and re-sharpened cutting knives undergo inspection by SEM (scanning electron microscopy) prior to certification for use.
CCSi UltraLife molds are manufactured from homogenous, solid, high carbon content A2 mold steel. Each undergoes precision grinding and CNC (Computer Numerical Control) machining to exacting requirements. The mold cavities are expertly honed and hand polished, after which the mold is industrial chrome plated.
Precision grinding ensures a parallel surface profile of the platens and CNC machining provides ultra-close dimensional tolerances, while the honing and polishing processes guarantee smooth, true specimen cavities. The durable, hard chrome finish resists the corrosive and adhesive effects of most compounds, greatly improving overall durability and ease of maintenance.
The CCSi UltraLife mold platens are thicker than standard molds, providing superior heat and pressure distribution, as well as extending the mold’s useful life by resisting distortion. This also allows the overflow recesses to be deeper, reducing problems associated overfill. The platens are positively positioned with precision guide pins and receivers … assuring precise closure!
CCSi UltraLife molds feature a unique cam-action hinge design which improves the critical distribution of pressure. Typical ‘fixed-hinge’ designs cause material to flow, outwardly, from this constraining point. This uneven application of pressure may cause excessive overfill, or cavity voids. The cam-action hinge design has all of the advantages of ‘stacked plate’ molds, combined with the convenience of ‘fixed-hinge’ designs!
The handles are manufactured from 304 stainless steel (a chromium – nickel austenitic alloy) and contain integral support pins. This allows the handles to rotate, which facilitates opening the mold. The handles are ergonomically positioned to ease placement and removal from the heated laboratory press.
Large triangular pry slots are located at the corners, opposite the cam-action hinges. These further facilitate mold opening and reduce the occurrence of cavity damage from improperly positioned tools.
