CCSi UltraLife Specimen Molds: ASTM D395
ASTM D395 UltraLife Specimen Mold
D395 UltraLife Specimen Mold
UltraLife Specimen Molds by CCSi
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 compression set, under constant force or under constant deflection, as indicated in ASTM D395Standard Test Methods for Rubber Property — Compression Set’.
The Type 1 specimen is used in both ASTM D395 ‘Test Method A’ and ‘Test Method B’, while the Type 2 specimen is used solely for ‘Test Method B’.
The ASTM D395 Type 1 specimens are also specified in, or may be used for:
ASTM D575Standard Test Methods for Rubber Properties in Compression’, Test Method A — Compression Set of a Specified Deflection;
ASTM D1229Standard Test Method for Rubber Property — Compression Set at Low Temperatures’.
CCSi UltraLife Specimen Molds: Quality Manufacturing
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 Specimen Molds: Innovative Design
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.
CCSi UltraLife Specimen Molds: Unique TriPlate Configuration
ASTM D395 TriPlate Specimen Mold
D395 UltraLife TriPlate Mold
The CCSi UltraLife TriPlate is a unique 3 platen mold designed specifically for specimens which are typically difficult to extract.
The TriPlate features a tertiary, centrally positioned, side-mounted platen, which precisely mold-forms the specimen between two 90º opposed plates. It opens to expose both horizontal specimen surfaces, greatly easing specimen removal.
Thicker specimens, which are prepared in dual platen laboratory molds, are often subject to damage caused by the difficulty of extraction. Specimen damage may go unnoticed, adversely affecting the repeatability and reproducibility of test determinations.
The CCSi UltraLife TriPlate configuration virtually eliminates the potential for specimen deformation caused by extraction, reducing the need for repeat testing and improving test results!
