COPPER ALLOYS FOR THE GLASS-MAKING INDUSTRY
METAL INDUSTRIEL offers a range of specially developed alloys for the glass industry, including MISV, MISV-M, MISV-S, and MISB. These alloys are available in various bar shapes tailored for mold production, such as half-moon bars machined to specifications and round bars selected according to final application requirements.
These materials are ideal for the manufacturing of:
- Ring molds
- Finisher molds
- Roughing bottoms
- and for Finishings
Thanks to a large inventory of standard dimensions and short production lead times, METAL INDUSTRIEL provides mold makers with maximum flexibility and fast delivery, even for specialized geometries.
Round bars
Produced by continuous casting in diameters that can exceed 200 mm. They are used for the manufacturing of mold bottoms.
Full Half-Moon or Hollow Bars
Manufactured by continuous casting, these bars are available in dimensions specifically adapted for the production of ring molds. The full range of sizes is available upon request.
Bars of Different Shapes
Produced by continuous casting and delivered pre-machined, these bars are designed for the fabrication of roughing bottoms and finishing molds. “L”-shaped bars are also available for the manufacture of tweezers and other specialized components.
THE MISV (Metal Industrial Spécial Verrerie)
The MISV range (including MISV, MISV-M, MISV-S, and MISB) consists of copper-based alloys with a nickel content exceeding 10%, specifically engineered for the glass industry.
These alloys offer mechanical and physical properties ideally suited for the manufacture of:
- Ring molds
- Finishing molds
- Roughing bottoms
- Final finishing components
The MISV alloys are designed to withstand the demanding operating conditions of glass mold production, offering exceptional resistance to:
- Working temperatures above 900°C
- Thermal shocks and heavy mechanical stresses
- Erosion and corrosion caused by glass composition and lubricants
This combination of high-temperature stability, durability, and corrosion resistance makes MISV alloys a reliable choice for maximizing mold life and performance in continuous production environments.
Advantages OF CONTINUOUS CASTING
Producing MISV semi-finished products by continuous casting offers a highly efficient and economical solution for manufacturing molds used in the production of bottles and other glass containers.
Key Metallurgical Benefits:
- Metal free of porosity
- Finer and more homogeneous grain structure compared to sand or shell casting
- This increased alloy uniformity contributes to a higher hardness and improved thermal conductivity
The resulting operational advantages are:
- Reduced machining costs
- Extended mold service life
- Smoother, cleaner surface finish, enabling precise machining from the start
- In many cases, near-net-shape casting minimizes both material waste and machining time
- Continuous casting not only enhances performance but also offers a cost-effective pathway to high-quality mold production.
