ASTM D638 Type IV Tensile Test Mold

This pre-assembled aluminum mold is engineered for producing standard ASTM D638 Type IV tensile test specimens. Designed for seamless integration with the APSX-PIM machine, it includes all necessary mounting hardware for immediate operation.

Product Overview & Specifications

• Mold Dimensions: 4.8″ (W) × 6.0″ (H) × 2.0″ (D)

• Test Specimen Produced: ASTM D638 Type IV Tensile Bar

• Part Dimensions: 4.75″ (L) × 0.75″ (W) × 0.125″ (Thick)

• Included Components: Pre-installed alignment pins & bushings, four (4) shoulder bolts, one (1) set of clamping claws.

• Note: Multiple mold orders include only one set of claws to be shared between frames.

Key Features & Benefits

• Ready for Production: Arrives fully assembled with all pins, bushings, and hardware installed. Simply mount and begin molding.

• Active Thermal Management: The specifically designed longer shoulder bolts create a passive cooling gap between the mold and the nozzle plate until the machine is fully clamped. This design significantly improves thermal stability and cycle time by reducing heat transfer.

• Precision Engineering: Tight-tolerance pins and bushings guarantee perfect mold alignment for consistent, high-quality, and flash-free test specimens every time.

Installation & Alignment Procedure

1. Mounting:

   • Secure the left side of the mold to the machine’s platen using the four (4) provided shoulder bolts.

   • Secure the right side using the included set of clamping claws.

2. Orientation: Ensure the top edge of the mold is perfectly flush with the top of Block 4 on the APSX-PIM.

3. Alignment Check:

   • Use the manual control buttons to initiate the clamping cycle.

   • Carefully observe as the mold halves begin to engage.

   • HALT the machine immediately once alignment is initiated.

4. Critical Safety Note: The pins and bushings are a tight, interference fit. They must be fully seated using the controlled force of the machine’s clamp. Do not attempt to press them together by hand, as this can cause injury or damage to components.

5. Finalize Installation: Once aligned, complete the clamping cycle. The mold will make full contact with the nozzle plate only at the final clamp position, ensuring proper injection.
