Selection and technical scheme of sand casting equipment
Sand casting is a traditional process for forming metal castings using sand molds. Its core process can be divided into the following six key steps:
1. Molding sand preparation
2. Mold making
3. Molding and assembly (automatic molding machine)
4. Melting and pouring
5. Cooling and sand shakeout
Our company's automatic molding machine is suitable for sand casting of complex-shaped castings (such as valves and gearboxes), and is particularly suitable for small-batch, high-variety production. Typical products our equipment can be used for include:
1. Engine blocks and transmission housings: Sand casting allows for complex internal structures.
2. Gears and bearing seats: Sand cores enable high-precision dimensional control.
3. Industrial valves and pipe fittings: Gate valves and ball valve bodies: The sand casting process allows for the simultaneous formation of flow paths and sealing surfaces.
4. Construction and engineering machinery components: Crane counterweights and excavator track shoes: Suitable for low-cost production of large castings.
5. Automotive and rail transit parts: Chassis brackets and train wheels: Suitable for small and medium-volume customization.
6. Aerospace non-load-bearing components: Aircraft brackets and instrument housings: Resin-bonded sand enhances surface finish. Cleanliness.
Automated molding machines significantly increase production and double efficiency. Manual molding takes about 30 minutes per piece, while automated molding machines (such as the vibration-compression type) can achieve a mold time of 3-5 minutes, a 6-10 times increase in efficiency. Under continuous operation, daily output can increase from 20-30 molds manually to 150-200 molds.
Advantages of Jinli's fully automatic molding machines:
Cost Optimization: Reduced Labor Dependence: One automated molding machine can replace 5-8 skilled workers, reducing labor costs by 60%.
Improved Sand Utilization: Increased sand mold density and a 20%-30% reduction in waste sand.
Quality Stability: Avoids loose sand and misaligned molds often seen in manual molding, reducing porosity by over 50%.
