4th Gen Automatic Vacuum Centrifugal Casting Machine Launched: Less Rubber Mould Waste, Higher Yield, Finer Zinc Alloy Badges & Medals
For badge and medal manufacturers who have long relied on manual or semi-automatic centrifugal casting machines, three persistent headaches remain: porosity, rough surface finish, and high rubber mould consumption. Our company has officially launched the 4th Generation Automatic Vacuum Centrifugal Casting Machine. Building upon three generations of mature centrifugal casting technology, this new model adds a built-in vacuum system and is specifically designed for low-melting-point alloys including zinc alloy, lead alloy, and tin alloy. Real-world production data confirms: noticeably finer surface finish, significantly less rubber mold waste, and a substantial increase in overall yield.

From Manual to Full-Automatic Vacuum: A Technological Leap
| Model | Core Features | Ideal for |
| Manual | Manual speed & timing control | Small batch |
| Semi-automatic vacuum | Constant speed motor, partial automation | Medium batch production, three-dimension |
| Full-automatic | Program-controlled, built-in furnace | High-volume production |
| Full-automatic vacuum | Vacuum degassing + reduced oxidation | High-volume production + finer surface |
The 4th generation retains full-automatic convenience, with the core upgrade being its integrated vacuum system. Air is rapidly evacuated from both the mould cavity and the molten alloy before casting, eliminating porosity at the source.
Three Key Customer Benefits of Vacuum Casting
Benefit 1: Finer, More Attractive Products
Vacuum removes gas from the molten alloy, eliminating porosity, shrinkage cavities, and flow lines. This is especially valuable for mirror-finish or high-standard electroplated badges and medals. Edge definition improves, and fine pattern details become sharper.
Benefit 2: Less Rubber Mould Waste, Lower Consumable Costs
Reduced porosity means less rework and scrap. Vacuum also lowers the frequency of rubber mould deformation under pressure. User feedback indicates rubber mold service life extends by 15-25%.
Benefit 3: Higher Yield Rate
Yield increases from the conventional 85-90% to 95-98% (depending on product geometry). The improvement is most pronounced for thin-walled, complex-shaped zinc alloy products. Less scrap equals higher profit.

Main Applications
Zinc alloy badges: party emblems, school badges, corporate logo pins, commemorative badges
Zinc alloy medals: sports medals, marathon medals, event souvenirs
Lead/tin alloy decorative items: pendants, keychains, small craft pieces, counterweights
If you produce any of the above and struggle with surface porosity or excessive rubber mould wear, this machine is worth testing.
