Semi-Automatic Vacuum Centrifugal Casting Machine Zinc Tin Metal Bracelet Production Equipment

Semi-Automatic Vacuum Centrifugal Casting Machine Zinc Tin Metal Bracelet Production Equipment

Product Overview

This semi-automatic vacuum centrifugal casting machine is cost-effective dedicated production equipment for manufacturing various zinc alloy and tin alloy bracelets, fashion bangles, decorative metal wrist ornaments and custom jewelry accessories. It perfectly matches the low melting point casting characteristics of zinc and tin alloys, widely applied in small and medium jewelry factories for mass production and personalized custom processing of all kinds of metal bracelets. Equipped with stable vacuum degassing and adjustable centrifugal speed system, it balances production efficiency and operation cost, being an ideal choice for medium-scale jewelry processing workshops.

Semi-Automatic Vacuum Defect-Free Casting

The built-in vacuum system can fully exhaust air and moisture inside the mould cavity during melting and centrifugal molding, effectively solving common defects including bubbles, pinholes, oxidation spots and incomplete pattern filling on bracelet blanks. Adopting semi-automatic control mode, the equipment realizes automatic vacuuming and constant temperature melting, with manual setting of centrifugal rotating parameters. It avoids frequent manual operation errors of traditional casting machines, greatly improving the surface compactness and yield rate of zinc tin alloy bracelet products.

High Precision Molding for Alloy Bracelets

Metal bracelets have high requirements for circular radian, surface flatness, embossed patterns and edge smoothness. With stable adjustable centrifugal force, molten zinc or tin alloy can evenly fill every detail of the silicone mould. The machine highly restores bracelet curved outlines, carved textures and decorative patterns, producing blanks with smooth surface, neat edges and uniform wall thickness. It greatly reduces the workload of subsequent polishing, trimming, electroplating and surface color treatment procedures.

Stable Operation & Wide Application

The machine features reinforced body structure, stable operation and low failure rate, supporting long-term continuous batch casting production. Except for various styles of metal bracelets, it is also compatible with pendants, earrings, medals and small craft ornaments made from zinc, tin, lead and other low melting alloys. Compared with fully automatic models, it has lower purchase and maintenance costs, simple operation and easy parameter learning, very suitable for medium-volume jewelry manufacturers to expand bracelet production lines.
