What is the ASTM D638 Type IV Tensile Test Mold?

The ASTM D638 Type IV Tensile Test Mold is a pre-assembled aluminum mold designed to produce standard Type IV tensile test specimens. Additive Plus in Los Angeles provides this mold for use with APSX-PIM machines.

What materials are used in the ASTM D638 Type IV mold?

The mold is machined from standard 6061 aluminum for precision and durability, ensuring consistent tensile test specimens.

What is the price of the ASTM D638 Type IV Tensile Test Mold?

The mold is available from Additive Plus at a price range of $500 to $1,750 depending on the selected options such as ejector pins.

Can I buy the ASTM D638 mold from Additive Plus in Los Angeles?

Yes, Additive Plus offers this mold for purchase directly from their Los Angeles location with shipping available nationwide.

What test specimens does this mold produce?

It produces ASTM D638 Type IV tensile bars with dimensions 4.75" (L) × 0.75" (W) × 0.125" (Thick) for standardized tensile testing.

Is the mold ready for immediate use?

Yes, the mold arrives fully assembled with all alignment pins, bushings, shoulder bolts, and clamping claws installed for immediate operation on the APSX-PIM.

What are the dimensions of the mold?

The mold dimensions are 4.8" (W) × 6.0" (H) × 2.0" (D), optimized for consistent tensile test specimen production.

Does the mold include alignment hardware?

Yes, the mold includes pre-installed alignment pins and bushings, four shoulder bolts, and a set of clamping claws for proper installation.

Can I order multiple molds?

Yes, Additive Plus allows multiple mold orders, but note that only one set of clamping claws is included and shared between frames.

What is the key feature of the active thermal management system?

The mold uses longer shoulder bolts to create a passive cooling gap between the mold and nozzle plate until fully clamped, improving thermal stability and reducing cycle time.

Is the mold compatible with APSX-PIM machines?

Yes, the ASTM D638 Type IV mold is specifically engineered for seamless integration with APSX-PIM injection molding machines.

How precise is the mold alignment?

Tight-tolerance pins and bushings guarantee perfect mold alignment for consistent, high-quality, flash-free tensile specimens every time.

What safety precautions are required for installation?

Pins and bushings are a tight interference fit and must be fully seated using the controlled force of the APSX-PIM machine clamp. Never press them by hand to avoid injury or damage.

How do I mount the mold on the APSX-PIM?

Secure the left side of the mold with the four shoulder bolts and the right side with the included clamping claws. Ensure the top edge is flush with Block 4 on the APSX-PIM before clamping.

What is the final step in mold installation?

Once aligned, complete the clamping cycle. The mold makes full contact with the nozzle plate only at the final clamp position to ensure proper injection.

Does the mold improve production efficiency?

Yes, pre-assembled design, active thermal management, and precise alignment reduce setup time and improve overall production efficiency.

What are the included components with the mold?

The mold includes alignment pins and bushings, four shoulder bolts, and one set of clamping claws. Multiple mold orders share the single set of claws.

Can the mold be used for research and development?

Yes, Additive Plus supplies this mold for R&D purposes, allowing engineers and material scientists to produce standardized tensile specimens for testing.

Is technical support available for mold installation?

Yes, Additive Plus provides technical guidance and support for safe and proper installation of the ASTM D638 Type IV mold.

Does the mold ensure consistent part quality?

Yes, precision-machined components and tight-tolerance pins and bushings guarantee repeatable, high-quality tensile test specimens.

What is the purpose of the passive cooling gap?

The passive cooling gap created by longer shoulder bolts reduces heat transfer to the mold until full clamping, improving thermal management and reducing cycle time.

Can the mold be used with other injection molding machines?

It is specifically designed for APSX-PIM machines. Compatibility with other machines may require custom adapters or modifications.

How does the mold maintain flash-free specimen production?

Precision pins, bushings, and tight assembly tolerances ensure the mold halves align perfectly, preventing flash during injection molding.

Is this mold suitable for commercial production?

Yes, Additive Plus ASTM D638 Type IV molds are designed for both R&D and commercial tensile specimen production.

Can the mold handle multiple injection cycles?

Yes, high-quality 6061 aluminum and robust hardware ensure durability and long service life for repeated injection cycles.

How do I order the ASTM D638 Type IV mold from Additive Plus?

You can place an order directly on the Additive Plus website or contact their Los Angeles office for a quote or bulk orders.

Does the mold come with an ejector pin option?

Yes, Additive Plus offers the mold with optional ejector pins to facilitate part removal and improve workflow efficiency.

Are there installation instructions included?

Yes, the mold comes with detailed installation instructions, including alignment, mounting, and safety precautions for APSX-PIM operation.

About this product

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

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

Unedited feedback from customers who reorder ASTM D638 Type IV Tensile Test Mold.

★★★★★ 4.9 / 5 · 24 reviews

★★★★★

Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Marcus K. Process Engineer · Aerospace OEM

★★★★★

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

Priya S. R&D Lead · Medical Devices

★★★★★

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
