Injection molding and/or Machining plastic ASTM Tensile & Flex specimens, Flame bars & Discs

 

Types of molded and/or machined test specimens:

1. Tensile: ASTM D638 Type I (0.125 inch thick * 0.50 wide * 6.50 long), a.k.a. dumbbell, dog-bone 

2. Specimens of special thickness, e.g. ASTM D638 Type I,  ASTM D1822-S(L) and other test bars, discs:  FAST TURNAROUND IS POSSIBLE, upon request, we CNC mill the requested cavity rapidly into a current or new mold plate or modify our 6.7 * 6.7-inch edge gated plaque mold to accommodate your thickness requirement (e.g. 0.010+ inch to 0.40+ inch) often in two days and water-jet or laser cut, stamp or CNC machine the specimens in Flow, Cross flow direction or at any angle between.  Regarding molded thin sections, our fast, accumulator-assisted injection molding machine can be employed to attempt the achievement of the required flow length in the specimen.    

3. Tensile: ASTM D638 Type IV  (0.051 inch thick * 0.25 wide * 4.50 long)   

4. Tensile: ASTM D638 Type V   (0.062 inch thick * 0.125 wide * 2.50 long)  

5. Flex bar: 0.125 inch thick * 0.50 wide * 5.0 long

6. Disc: 0.040 inch thick * 2.50 Dia. 

For 1, 2, 4, 5 and 6 types high-volume specimen molding is offered depending upon the polymer.  

The specimens are molded under highly controlled molding and desiccant drying (if needed) conditions, which can be specified by our clients.
