Ejector Pins: Precision Components for Injection Molding
Ejector pins are vital components in the injection molding process, designed to ensure the seamless removal of molded parts from the mold cavity. These precision-engineered pins push the solidified part out of the mold without causing damage, preserving the quality of both the molded product and the mold itself.
As a key element in mold design, ejector pins enhance production efficiency, reduce cycle times, and support high-volume manufacturing.
Core Functions

Why Fecision for Mold Components?
Precision and Accuracy
Using state-of-the-art CNC machining, EDM, and other advanced manufacturing techniques, Fecision ensures all mold components meet tight tolerances and high-quality standards.
Customization
Fecision understands the unique needs of each project. Our team works closely with customers to provide tailored solutions, ensuring that each component fits perfectly within the target mold system.
Rapid Prototyping
Fecision offers rapid prototyping for mold components, enabling customers to test and refine designs quickly before moving into full production.
End-to-End Services
From initial design and DFM (Design for Manufacturability) analysis to final mold assembly and testing, Fecision handles every aspect of the mold component manufacturing process.
Process for Manufacturing Mold Components
Manufacturability Evaluation
The initial step involves assessing the manufacturablity of the mold component. If it's deemed feasible, we proceed with production immediately. If not, we will provide a detailed DFM (Design for Manufacturability) report to the customer. If necessary, mold flow analysis is performed to simulate the flow of molten material within the mold.
Material Selection
Next, choose the right material for mold parts. Common materials for mold components include steel alloys, aluminum, stainless steel, specialty alloys, etc. If needed, a prototype may be made using rapid prototyping techniques (e.g., 3D printing, CNC machining) to test the design for fit, function, and manufacturability.
Mold Components Manufacturing
Once the design and materials are finalized, the mold component undergoes CNC machining. If required, the mold component may undergo heat treatment, depending on the material and intended application. For certain components, surface hardening methods such as nitriding or carburizing are applied to increase wear resistance.
Shipping
For molds with multiple components, such as multi-cavity molds or molds with inserts, the individual components are carefully assembled into the final mold system. Once our engineers confirm the product meets all requirements, it will be shipped. We maintain ongoing communication to ensure the customer is fully satisfied with the product they receive.
