Why HTX Step Ejector Pins?
Step Ejector Pins deliver stable, controllable, and durable ejection strokes, making them suitable for precision plastic molds that rely on the pins themselves for positioning. It is also called the shoulder ejector pin.
During mold operation, are you troubled by issues such as inconsistent ejection height, unsynchronized ejection in multi-cavity molds, and premature wear of limiters? HTX strictly controls step height and concentricity to ensure stable and reliable ejection stroke performance; meets the specific requirements of multi-cavity molds and maintains uniformity; uses precision grinding processes to reduce wear; and supports highly repeatable custom designs, thus guaranteeing the long-term stable operation of the ejection mechanism.
If you require the ejector pin itself to control the stroke, the HTX Step Ejector Pin is your best choice.
Step/Stepped Ejector Pin Types
Step ejector pin/shoulder ejector pin provides reliable stroke positioning in multi-cavity molds, precision molds, and mold structures with strict restrictions on ejector height.
Features a single-step structure, suitable for multi-cavity molds and precision molds requiring basic stroke limitation, providing a reliable stroke control solution.
The multi-stage stepped design allows for segmented ejection, making it suitable for precision machining processes that require staged or variable-stroke ejection.
Supports customization of step height and diameter based on drawings to meet non-standard structures and special functional requirements, delivering high adaptability.
The Application of The Step Ejector Pins
In these cases, controlling the ejection length through the stepped design of the ejector pins themselves enhances mold stability and simplifies the assembly process.
Multi-Cavity Injection MoldsStepped ejector pins ensure that the ejection height is consistent across all cavities, preventing product height variations caused by asynchronous ejection and improving multi-cavity yield rates.
Precision Limited EjectionThis ejector pin precisely controls ejection distance through its stepped structure, preventing inconsistent ejection lengths or incomplete demolding to ensure consistent ejection dimensions.
Height-Sensitive ComponentsThe stepped ejector pin design delivers stable, repeatable limiting action, effectively prevents product damage caused by inconsistent pushing or lifting heights.
Simplified Mold StructureStepped ejector pins can be used directly as limit stops, eliminating the need for additional limiting components. This ensures consistent product ejection while reducing mold complexity and maintenance costs.
Customization of The Step Ejector Pins
The step ejector pin can be customized according to the drawing you provide. If you are unable to create a drawing, our professional engineering team can design suitable tolerances based on the drawings you provided. Once confirmed, we will arrange the sample production. Additionally, we maintain a large inventory of standard sizes for quick shipment. Please just provide your parameter to inquire about current stock availability.
A step ejector pin controls the ejection stroke length through its stepped structure, while a straight ejector pin lacks this limiting function.
If you only have product images, we cannot provide customization. You must create corresponding 3D design drawings based on the plastic mold design of your product. Then we can process the pins according to these drawings.
If your mold has strict requirements for ejection stroke length, synchronization, and product consistency, a batch-stable step ejector pin can meet your needs.
