Zamak Letter Lapel Pin Fashion Letter Zinc Alloy Brooch Semi-Automatic Centrifugal Casting Equipment 

Product Description

The Semi-Automatic Centrifugal Casting Equipment for Zamak Letter Lapel Pins is specially designed for producing fashion letter brooches and alphabet-style zinc alloy lapel pins. It is widely used in fashion accessories, personalized jewelry, and promotional gift manufacturing.

The machine adopts centrifugal casting technology combined with semi-automatic operation to ensure precise mold filling, sharp edge reproduction, and smooth surface quality. It is ideal for producing high-detail letter designs with stable and consistent output.

Working Principle

The machine melts Zamak alloy in a temperature-controlled crucible until fully molten. The mold is then placed into the centrifugal chamber. Once activated, the system rotates at high speed, generating strong centrifugal force that pushes the molten metal evenly into every detail of the letter mold cavity, including fine edges, curves, and complex typography structures.

This process ensures excellent mold filling capability, producing lapel pins with a dense internal structure, clear contours, high detail accuracy, reduced porosity, and smooth surface finish.
