Addressing Three Real-World Challenges in Pendant Production

In the actual production of zinc alloy keychains and pendants, do you often encounter these problems?

• Too many styles, too much downtime: Orders are typically "high-mix, low-volume." Every mold change requires tedious manual adjustments, making it nearly impossible to maintain efficiency;

• Complex shapes, high scrap rates: Pendants often feature thin walls, hollow sections, or double-sided reliefs. Ordinary casting leads to porosity and cold shuts, and the subsequent welding and polishing eat away at your profit margins;

• Inconsistent quality between sides: Poor metal flow results in a full front but a short-fed back. The two sides of the same pendant look completely different, making quality control a nightmare.

This Semi-Automatic Centrifugal Casting Machine was designed specifically to solve all three of these problems at once.

Vacuum Assistance: Perfect Casting in a Single Shot

The built-in Vacuum Assistance System fundamentally changes the way molten metal fills the mould:

• Air Evacuation Eliminates Porosity: Once the mold is closed, the system pre-evacuates the cavity. With zero air resistance, the molten metal instantly fills even the finest lettering and openwork details—completely eliminating defects caused by trapped air;

• Consistent Quality on Both Sides: The vacuum environment significantly improves metal flow. Whether it's a raised relief on the front or engraved text on the back, both sides fill simultaneously – ensuring perfect uniformity between front and back, with no "good side/bad side" issues;

• Less Rework, Lower Costs: One casting cycle delivers a smooth, clean surface, drastically reducing the need for post-casting welding, grinding, and polishing. Overall yield rate is pushed to over 98%.

Semi-Automatic Design: Quick Changes, Stable Operation, One Operator for Multiple Machines

Addressing the "frequent style changes" reality of pendant production, we've deeply optimized for operational convenience:

• Quick-Change Mould System: No complex tools required – molds can be changed and locked within minutes. Changeover speed is 50% faster than traditional manual models, making even small-batch orders profitable and stress-free;

• Standardized Operation: Semi-automatic mold opening/closing and assisted pouring transform skilled craftsmanship into a consistent, repeatable rhythm—new operators can be productive after just half a day of training, with quality no longer dependent on individual skill;

• Effortless Multi-Machine Management: Significantly reduced physical workload allows one operator to easily manage 2-3 machines simultaneously, cutting labor costs in half while doubling production output.

Applicable Products

This machine is widely used for precision casting of zinc alloy keychain bodies, bag tags, and other small pendants. It is particularly well-suited for orders with diverse styles and tight delivery deadlines.
