The equipment and tools used in the vacuum casting process have a significant impact on the quality and productivity of the final product. The following is a description of some of the major vacuum remolding equipment:
1. Vacuum Pump
Vacuum pump is the core equipment used to pump out the air in the mold cavity to ensure a vacuum environment inside the mold.
- Rotary vane vacuum pump: for low to medium vacuum requirements.
- Turbo-molecular pump: for high vacuum requirements, usually used in combination with a pre-pump.
- Dry vacuum pumps: oil-free design for applications with high cleanliness requirements.
2. Vacuum chamber
Vacuum chambers are used to hold molds and injection materials and to inject and cure the materials after evacuation.
- Single station vacuum chamber: suitable for small batch production and R&D purposes.
- Multi-station vacuum chamber: Suitable for mass production to improve production efficiency.
3. Injection Molding Machine
Injection molding machines are used to inject liquid materials into molds and ensure uniform distribution and curing of materials.
- Manual Injection Molding Machine: Easy to operate and suitable for small-scale production and prototyping.
- Semi-Automatic Injection Molding Machine: Combines manual and automatic functions to increase productivity.
- Full-automatic injection molding machine: fully automated operation, suitable for mass production.
4. Molds
Mold is the key component to form the shape of the product. Different types of molds can be selected according to the complexity and material of the product.
- Silicone mold: commonly used for making prototypes of complex shapes and small batch production.
- Resin mold: For products requiring high precision and durability.
- Metal molds: for mass production with high durability and precision.
5. Heating Equipment
Heating equipment is used to accelerate the material curing process to ensure product quality and productivity.
- Hot air circulation oven: for curing small and medium-sized products.
- Infrared heater: suitable for rapid heating and localized heating.
- High temperature oven: for materials and products that require high temperature curing.
6. Control system
The control system is used to monitor and regulate the parameters in the vacuum remolding process, such as temperature, pressure and time.
- PLC control system: programmed logic control for complex production processes.
- Touch screen control system: friendly interface, easy to operate.
7. Auxiliary tools
Auxiliary tools are used for mold preparation, material mixing and product trimming.
- Stirrer: used for uniform mixing of remolding materials.
- Scrapers and spatulas: for material application and surface treatment.
- Shears and saws: for cutting and trimming of molds and products.
Through the reasonable configuration and use of these equipments, the efficiency and product quality of vacuum remolding process can be greatly improved.
