What are the Different Types of Injection Molding Gates?
Injection molding gates come in a variety of types, each with its unique characteristics and applications. Choosing a suitable gate can significantly impact product quality, production efficiency, and cost.
Common types of injection molding gates include:
Direct Gate
Characteristics: The gate is located directly on the product surface, making it simple in structure and easy to process.
Advantages: Low cost and easy to process.
Side Gate
Characteristics: The gate is located on the side wall of the cavity, forming a certain angle with the cavity wall.
Advantages: Smaller gate mark, suitable for products with higher appearance requirements.
Submerged Gate
Characteristics: The gate is hidden inside the cavity, leaving no obvious gate mark.
Advantages: Good product appearance with no obvious gatemark.
Circular Gate
Characteristics: The gate is distributed in a circular shape around the product.
Advantages: Even filling and reducing weld lines are suitable for thin-walled long tubular products.
Disadvantages: Difficult to remove the gate.
Pin Gate
Characteristics: The gate is pin-shaped with a small diameter.
Advantages: Suitable for multi-point gating, reducing weld lines.
Fan Gate
Characteristics: The gate is fan-shaped, suitable for large-area thin-walled products.
Advantages: Even filling, reducing warpage and deformation.
