There are many types of gravity die casting machines. The work of each type of gravity die casting machine is different. The gravity casting machine is one of the basic processes of modern mechanical manufacturing process. The gravity die casting machine uses the casting technology to melt the metal into a liquid that meets certain requirements and pours it into the mold, and then cools and solidifies to obtain a casting machine having a predetermined shape, size and performance. Next, we will take a look at the technical summary of the gravity die casting machine.
1. Selection of resin and curing agent.
At present, the most used in the world is bisphenol-A epoxy resin. Unsaturated polyester resin is also used in Europe and America. Other resins are available, but the use occasions and process control and bisphenol-A epoxy resin have Difference
2. Additives for resins and curing systems
3. Use different gradations for different structures
4. The desiccant used to dry the filler and aggregate, or the necessary process
5. Reasonable mixing of resin and curing agent
6. Design and production of vibration table
7. Vibration scheme necessary for tamping mineral castings
8. Production points of grouting sheet metal
9. According to the performance of mineral castings, reasonable structural design ensures that the advantages of mineral castings can be maximized.
10. Mold design, including molds for steel molds, wood molds and other materials
11. Gel coat making formula, and use method to ensure smooth and beautiful surface of mineral casting demoulding
12. Internal reinforcement of mineral castings greatly increases the rigidity of mineral castings
13. Mold core production
14. Post-cure treatment of mineral castings
15. Quality control of raw materials and mineral castings
16. Bonding technology between different mineral casting parts
17. Secondary copying technology for precision surface of mineral castings
18. Formulation of filler material for weight gain or vibration absorption
