Controlling the injection pressure and speed is crucial during the wax injection process, as it directly affects the quality and production efficiency of the wax mold. Here are some key control methods and precautions: how to control the pressure and speed of wax injection in the wax injection machine

Control of injection pressure
Pressure setting:
Reasonably set the injection pressure based on the shape and size of the mold, the fluidity of the wax liquid, and the required accuracy of the wax mold. Generally speaking, the injection pressure needs to be adjustable within a certain range to meet different production needs. For example, the wax injection pressure of some fully automatic cylinder free wax injection machines can be adjusted within the range of 0-6.3MPA.
Stable pressure:
During the injection process, stable injection pressure should be maintained as much as possible to avoid pressure fluctuations that may cause uneven distribution of wax or deformation of the mold.
The injection pressure can be monitored and adjusted in real time through pressure sensors and control systems to ensure that it fluctuates within the set range. How to control the pressure and speed of wax injection in a wax injection machine
Mold support:
When the injection pressure is high, special attention should be paid to strengthening the support of the mold to prevent damage due to uneven force.
Control of injection speed
Speed setting:
Reasonably set the injection speed based on the fluidity of the wax and the complexity of the mold. A too fast injection speed may cause wax splashing or the formation of bubbles inside the mold, while a too slow speed may prolong the production cycle. How to control the pressure and speed of wax injection in a wax injection machine
Some wax injection machines are equipped with adjustable wax injection speed controllers, allowing operators to set the appropriate injection speed as needed. For example, the maximum wax injection speed of some wax injection machines can reach 0.3L/s.
Uniform injection:
During the injection process, it should be ensured that the wax is injected into the mold at a uniform speed to avoid uneven quality of the wax mold due to local injection being too fast or too slow.
Uniform injection can be achieved by adjusting the speed of the injection pump or using precision control devices such as servo motors.
Other precautions
Preheating mold:
Before injection, the mold should be preheated to increase its temperature and reduce the temperature difference between the wax and the mold. This helps improve the fluidity of the wax and reduce condensation on the surface of the mold. How to control the pressure and speed of wax injection in a wax injection machine
Wax liquid temperature control:
The temperature of the wax solution is also one of the important factors affecting the injection effect. Excessive temperature of the wax solution may lead to increased shrinkage rate or defects such as bubbles in the wax mold; However, if the temperature is too low, it may affect the fluidity of the wax liquid and cause the surface of the wax mold to become rough. Therefore, the temperature of the wax solution should be strictly controlled and kept within an appropriate range during the injection process.
Regular maintenance:
Regular maintenance and upkeep of the wax injection machine are also key to ensuring stable and controllable injection pressure and speed. This includes cleaning equipment, inspecting component wear, replacing worn parts, and calibrating control systems.
In summary, by setting and adjusting the injection pressure and speed reasonably, as well as paying attention to other related matters, it is possible to ensure the smooth progress of the wax injection process and produce high-quality wax molds.
