Plastic Injection Molding What Is It? How Does It Work?
An injection molding gate is a critical component in mold design, acting as the passage through which molten plastic travels from the runners into the mold cavity. Its design significantly impacts the final product's appearance, strength, and functionality, making it crucial for manufacturers to understand its intricacies and variations thoroughly.
Injection Molding Gate & Gate Design Plastopia
Gates in plastic injection molding refer to openings through which molten plastic passes to enter the mold cavity. As the name suggest, they serve as gateways - passage - for liquid plastic components to enter the mold cavity. Injection molding gates occur in different forms, taking distinct sizes and shapes - appearing narrow, wide, tapered, etc.
