What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.
About this product
This is a ready-to-use, standard-size aluminum mold designed specifically for producing plastic test bars for ASTM D790 Flexural (Bend) Testing. The mold comes fully assembled with all necessary hardware, allowing you to start producing consistent, high-quality test samples immediately upon installation.
Core Specifications:
-
Mold Frame Dimensions: 4.8″ W × 6.0″ H × 2.0″ D
-
Sample Part Size: 4.28″ L × 0.50″ W × 0.125″ Thick (Standard ASTM D790 Specimen)
-
Compatibility: Designed for use with the APSX-PIM series injection molding machines.
What’s Included:
-
CNC-machined 6061 aluminum mold with pre-installed alignment pins and bushings.
-
Four (4) shoulder bolts (for left-side mounting).
-
One (1) set of clamping claws (for right-side mounting).
-
Note: Orders for multiple molds include only one set of claws.
-
Key Features & Benefits:
-
Pre-Installed Hardware: Alignment pins, bushings, shoulder bolts, and claws are installed. No assembly is required; you can mount it and begin production.
-
Integrated Thermal Management: The shoulder bolts are engineered to be intentionally longer. This creates a small insulating air gap between the mold and the machine’s nozzle plate when unclamped, helping to keep the mold cooler and improve cycle times.
-
Precision Alignment: The tight-tolerance pins and bushings ensure perfect alignment of mold halves for consistent part quality and flash-free samples.
Installation & Usage Instructions:
-
Mounting: Secure the left side of the mold using the four included shoulder bolts. Secure the right side using the provided claws.
-
Orientation: Ensure the upper side of the mold is flush with the upper side of Block 4 on the APSX-PIM machine.
-
Alignment Check:
-
Use the machine’s manual control buttons to initiate the clamping cycle.
-
HALT the machine immediately as the mold halves begin to mate.
-
Important: The pins and bushings are a tight, press-fit. They must be seated using the machine’s clamping force or a manual press. Do not attempt to press them together by hand.
-
-
Operation: Once aligned, complete the clamping cycle. The mold will make full contact with the nozzle plate only at the end of the clamp stroke, eliminating the insulating gap for the injection phase.

Unedited feedback from customers who reorder ASTM D790 Flexural Test Mold.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

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.

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.
