Injection molding equipment possesses several key characteristics:

1. Accurate control: Topstar injection molding machines can precisely control factors such as temperature, pressure, and speed, ensuring consistency and high quality in production.
2. Multifunctionality: These plastic molding machines can produce various plastic products, ranging from small to large components, with varying complexity and shapes.
3. Improving efficiency: Injection molding is known for its high production efficiency, as it can achieve fast production cycles and minimize material waste.
4. Injection molding automation: Many injection molding processes are highly automated, reducing the need for physical labor and improving productivity.
5. Injection unit: The machine’s injection unit can melt plastic particles and inject the melted material into the mold cavity.
6. Locking device: The locking device fixes the half mold together during the injection process and provides the force required to keep the mold closed.
7. Cooling system: After injection, the mold must be cooled to solidify the plastic. The injection molding machine has a complex cooling system that regulates the mold’s temperature.
8. Injection pressure: Carefully control the pressure of molten plastic injected into the mold to ensure correct filling and cavity pressure retention.
9. Material processing: Injection molding equipment typically includes a system for processing and feeding plastic particles into the machine to ensure a continuous supply of materials. These characteristics have led to the widespread application of injection molding in producing plastic parts and products in various industries.
The Topstar direct compression injection molding machine generates high pressure directly on the sheet metal by the locking cylinder. The force point is in the same direction as the pressure inside the mold cavity, achieving central locking of the mold.
