Medium temperature wax injection machine is a precision equipment specifically used for melting medium temperature wax materials (usually with a melting point range of 60-120 ℃) and injecting them into molds. It is widely used in precision casting (lost wax casting/investment casting), jewelry, medical equipment and other fields. The following is a detailed introduction to the medium temperature wax injection machine:
1、 Basic structure and working principle
1. Core components:
(1) Wax melting system:
Wax melting tank: made of stainless steel material, equipped with heating device (electric heating or oil bath heating), temperature can be accurately controlled (± 1 ℃).
Insulation system: prevents wax from solidifying and maintains constant temperature fluidity.
(2) Wax injection system:
Wax injection cylinder/syringe: Inject wax into the mold through pneumatic (compressed air) or hydraulic drive.
Wax nozzle: adjustable flow rate to adapt to different mold cavities.
(3) Control system:
PLC or microcomputer control, adjust wax injection pressure (0.1~0.6MPa), temperature, time and other parameters.
Some models are equipped with touch screens that support storage of multiple sets of process parameters.
(4) Mold clamping device:
Manual or automatic locking mechanism to ensure the sealing of the mold.
2. Workflow:
(1) Molten wax: Solid wax blocks are heated to a molten state (usually 80-100 ℃), filtered for impurities, and stored in an insulated tank.
(2) Wax injection: After preheating the mold, the wax liquid is injected into the mold cavity at high speed or low pressure through the wax injection nozzle (depending on the complexity of the product).
Cooling demolding: After the wax mold solidifies, the mold is opened and removed for subsequent trimming or tree assembly.
2、 Main features
1. High precision wax injection:
Stable pressure, clear wax mold contour, reducing defects such as bubbles and material shortages.
Suitable for complex thin-walled components such as turbine blades and dental restorations.
2. Precise temperature control:
Segmented temperature control (wax melting zone, wax injection pipeline, mold preheating) to avoid wax liquid overheating, carbonization or low-temperature blockage.
3. Multi mode wax injection:
Low pressure wax injection: reduces turbulence, suitable for precision parts.
High pressure wax injection: rapid filling to improve efficiency.
4. Energy conservation and environmental protection:
The closed wax melting design reduces volatilization, and some models are equipped with wax smoke collection devices.
