Tailored service plan
What your metallography lab actually checks
Edge retention to the surface
Hot compression mounting keeps AM and coated samples tight to the resin, so surface layers, edges and thin coatings survive grinding without rounding — exactly what matters when you measure layer thickness or near-surface porosity.
An applications engineer on the line
Method setup, consumable selection and troubleshooting from engineers who run sample prep and materials characterization in-house. Sub-4h reply, NDA standard.
About this product
The QATM OPAL 410 is a fully automatic hot mounting press. It embeds metallographic and additive-manufacturing specimens in thermosetting resin so edges stay flat and protected through grinding and polishing — a clean, repeatable mount is the foundation of every reliable cross-section.
Why labs choose the OPAL 410
Hands-off hot mounting with edge retention you can trust.
Fully automatic program
Set pressure, heating and cooling once, press start. Parameters can be adjusted live during the cycle.
Edge retention
Hot compression mounting holds the sample tight to the resin so surface layers and coatings don’t round off when you grind.
Water-saving cooling
Continuous or pulsed water cooling — pulsed mode cuts water consumption markedly.
Two mounts per cycle
Mould assemblies Ø 25.2–40 mm in six sizes; run two mounts at once with a spacer.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
Which mould sizes does the OPAL 410 accept?
The OPAL 410 takes mould assemblies from Ø 25.2 to 40 mm in six different sizes, and can produce two mounts at once when you fit a spacer. Assemblies change quickly and without tools thanks to the bayonet closure, so switching sample sizes between jobs is fast.
Does the OPAL 410 preserve edges on coated or additively-manufactured samples?
Yes. Hot compression mounting presses the resin tight against the specimen so surface layers, coatings and part edges stay flat and don't round off during grinding. Combined with an edge-retention resin, the OPAL 410 keeps near-surface features intact — important when you measure layer thickness, case depth or near-surface porosity on AM parts.
How is cooling handled on the OPAL 410, and can I reduce water use?
The mounting process is cooled with either continuous or pulsed water flow. Pulsed cooling achieves a considerably lower water consumption while still cooling the mount properly, so the OPAL 410 fits labs that watch utility use or run many cycles per day.
What resins can I run in the OPAL 410?
The OPAL 410 works with standard hot-mounting resins — phenolic, epoxy, acrylic, conductive and edge-retention grades — chosen for your material and downstream analysis. Six selectable pressures let you match the resin and sample diameter. Additive Plus configures the resin and mould set with the press before shipping.
What is the lead time for the OPAL 410 and what's included?
The OPAL 410 is configured to your specimens and built to order, so lead time depends on the current configuration and production queue — request a current timeline and we'll confirm it in writing. Every unit includes installation and operator training plus a tailored service plan. Additive Plus is an authorized QATM channel, so sales, setup, training and service run through one partner. Tell us your materials and sample sizes and we'll quote the right configuration.
What support does Additive Plus provide after the OPAL 410 is installed?
After the OPAL 410 is installed and your team is trained, you get method help, consumable selection and troubleshooting from engineers who run metallographic sample preparation in-house — not a remote ticket queue. Reply times are under 24 hours, typically sub-4h, NDA standard. A tailored service plan covers maintenance and spare parts so the machine stays in production, and we help dial in methods for your specific alloys.
How does the OPAL 410 fit additive-manufacturing quality control?
Reliable AM QC — porosity and density counts, grain and phase analysis, layer-bonding and weld inspection, failure analysis — all start from a correctly prepared cross-section. The OPAL 410 is one step in that chain (sectioning, mounting, grinding, polishing, etching and optical analysis), and Additive Plus can supply the whole chain so results stay consistent and defensible. Send a specimen and we'll prepare it as a service before you commit.
