Guide rails are small components with a measurable effect on tablet press stability.

Hanlin Hangyu selected AMPCO® 21 for high-stress guide rail positions where repeated sliding contact, surface pressure, and wear can affect dosing consistency and component service life.

The technical basis is measurable:
• 285–302 HBW hardness contributes to wear resistance
• A coefficient of friction of 0.21 enables stable movement
• Compressive strength up to 1,335 MPa helps withstand high surface pressure

According to Hanlin Hangyu, AMPCO® 21 supports reduced wear, longer guide rail service life, and smoother tablet press operation.

We're live at INTERPLAST 2026 in Joinville, through 28 August.

The full plastics production chain is under one roof this week, and members of our engineering team are on hand to review the tooling positions where heat extraction is limiting cycle time and dimensional consistency.

In injection molding, where a cooling channel cannot reach, the tooling material carries the heat load, and the rate at which that heat leaves the mold governs both cycle time and dimensional consistency. This is the constraint AMPCOLOY® high-conductivity copper alloys are engineered to address, offering higher thermal conductivity than the P-20, H-13, and 420 steels used in the same positions.

📍Booth 2, Aisle A. We look forward to meeting with you.

Three new areas on the AMPCO METAL website, reflecting where copper alloys are gaining ground:

▪️Hydrogen: validated alloy solutions for hydrogen infrastructure, backed by independent testing at DECHEMA.

▪️Additive Manufacturing: copper alloy components produced through advanced manufacturing methods for demanding geometries and performance requirements.

▪️Luxury: high-performance alloys for premium applications where surface quality, durability, and material character matter.

AMPCO METAL will be at INTERPLAST, Brazil's only full plastics-chain trade show, held 25–28 August at the Expoville pavilions in Joinville, Santa Catarina.

In plastic injection molding, the rate at which heat leaves the mold - through cores, inserts, and cavities - governs cycle time and dimensional consistency. Where a cooling channel can't reach, the tooling material carries the load.

This is where AMPCOLOY® high-conductivity copper alloys do their work, with thermal conductivity well above the P-20, H-13, and 420 mold steels used in the same positions.

Our engineering team will be present throughout to review your tooling and the positions where a change in material could recover capacity.

Come and find us at Booth 2, Aisle A.

When you're choosing materials for hydrogen service, the alloy name alone won't tell you whether a component is safe.

Hydrogen embrittlement depends on how hydrogen, stress, and microstructure combine. High-strength steels are a common concern because susceptibility often rises with strength and hardness, which is why hydrogen specifications frequently cap those values. But microstructure, processing history, heat treatment, welds, and geometry all shift the outcome too.

That's why material selection for hydrogen has to weigh compatibility alongside mechanical strength, corrosion behavior, thermal performance, wear, and manufacturability in the final processed condition, not just the base alloy.

AMPCO METAL supports engineers in evaluating copper-based alloy options for demanding hydrogen service environments.

When a mold is expected to run for millions of shots, small differences in heat transfer and wear resistance matter.

Mould-Tip uses AMPCOLOY® 83, 88, and 940 in nozzle, core and mold cavity applications for hot runner systems and multi-cavity packaging molds.

AMPCOLOY® 88 and 940 support heat transfer, with thermal conductivity of 230–287 W/m·K (20°C-300°C) and 208–243 W/m·K (20°C-200°C) respectively. AMPCOLOY® 83 is used where higher hardness and strength are required, with 360–380 HBW hardness and tensile strength up to 1,250 MPa.

Mould-Tip reports improved thermal control, stable performance during extended production cycles, reduced downtime, and mold lifetimes reaching tens of millions of shots.

Hydrogen infrastructure is shifting from project ambition to physical build-out and that changes what engineers have to design for.

As pipelines are repurposed, storage cycles involve repeated injection and withdrawal, ports handle hydrogen carriers, and refueling corridors operate under demanding duty cycles. In these environments, components face combined exposure to pressure variation, contact stress, friction, corrosion, and heat.
A part that performs well in conventional service still has to be assessed for hydrogen exposure in its final processed condition, geometry, and loading mode.

The takeaway: as infrastructure scales, material qualification moves closer to the center of the engineering decision and engineers need options that don't narrow the design window unnecessarily.

Clean hydrogen only works if the metals around it stay strong.

AMPCO® 18 and AMPCOLOY® 83 were tested for hydrogen embrittlement at Germany's DECHEMA Institute and showed no indication of it, though final components should still be validated in their end state.

In automotive injection molds, the most thermally critical zones are also the hardest to cool, such as speaker grille areas in door panels or dashboard visor sections, where narrow cavities and thin walls limit where cooling channels can be machined.

For Qingdao High-Tech Mold Co., Ltd., the response is to use AMPCOLOY® 83, 940, and 944 in those zones, transferring heat through the tool material itself rather than relying solely on coolant flow.

Thermal conductivity:
- AMPCOLOY® 940: 208–243 W/m·K (20–200 °C)
- AMPCOLOY® 944: 156–190 W/m·K (20–200 °C)
- AMPCOLOY® 83: 106–157 W/m·K (20–300 °C)

By comparison, common mold steels such as P-20 and H-13 typically remain below 30 W/m·K.

In the testimonial, High-Tech Mold reports cooling-phase improvements of 20–40%, depending on mold geometry and application.
