Wax injection machine is a key equipment in precision casting, belonging to the mold making equipment in precision casting equipment. What is wax injection machine? What is the working principle of the wax injection machine? What are the types of wax injection machines? Next, the editor will answer each question for you one by one.
1. What is a wax injection machine?
Mainly used to inject melted wax into molds and make wax molds.

2. Working principle
(1) Melting wax material: Heating solid wax (such as paraffin, beeswax, synthetic wax, etc.) to a liquid state.

(2) Pressure injection: Injecting liquid wax into a metal mold through air pressure or plunger to fill the cavity.

(3) Cooling demolding: After the wax material solidifies, open the mold and remove the wax mold for subsequent processes such as shell making, dewaxing, and casting.

3. Main types
(1) Manual wax injection machine: easy to operate, suitable for small batch production, relying on manual control of pressure and temperature.

(2) Semi automatic/fully automatic wax injection machine: Control injection parameters (pressure, temperature, time) through PLC or CNC system, suitable for large-scale high-precision production.

(3) Vacuum wax injection machine: Inject wax in a vacuum environment to reduce bubbles and improve the surface quality of wax molds.

4. Core components
(1) Wax cylinder: a container for storing and heating wax materials, equipped with a temperature control device (usually 60-90 ℃).

(2) Injection system: pneumatic drive or mechanical pumping to ensure rapid filling of the mold with wax material.

(3) Mold clamping device: fix the mold and ensure the accuracy of mold clamping.

(4) Control system: Adjust parameters such as temperature, pressure, injection speed, etc.
