Engineered Copper Alloys for the Plastic Processing Industry
Plastic processing demands precision, efficiency, and durability. From injection molding to extrusion and blow molding, manufacturers face constant pressure to reduce cycle times, improve product quality, and extend tool life. AMPCO METAL supports this industry with its AMPCOLOY® high-copper alloys, which provide excellent thermal conductivity and high wear resistance resulting from their inherent hardness. Complementing these, the AMPCO® aluminum-bronze alloys offer superior sliding properties and high mechanical strength, ensuring long service life even in demanding environments
Challenges in the Industry
- Slow cooling cycles increase production costs and limit throughput.
- Part warpage and defects compromise product quality and increase scrap rates.
- Tool wear and maintenance lead to downtime and higher operating costs.
- Aggressive resins can cause corrosion and shorten mold lifespan.
Applications in Plastic Processing
Injection Molding
Core and cavity inserts, cooling pins, hot runner nozzles, neck rings.
Blow Molding
Pinch-offs, neck rings, mold cavities.
Extrusion
Calibrators for cooling long profiles, with up to 300,000 meters produced before tool change.
Thermoforming
Welding electrodes in AMPCO® bronze for stable HF welding performance.
