Product Overview

Still struggling with demoulding of deep-cavity, inverted, or easily deformable articles? High performance secondary ejection standard is your ideal choice. We offer ready-to-use, high-precision, high-reliability standard kits that simplify your mold design, dramatically increase the yield and productivity of complex products, and reduce mold maintenance costs.

Product Features

1. Clarify the working principle:
Demoulding step by step to protect products: The secondary ejection system realizes two independent ejection operations through precise mechanical sequential control mechanisms (e.g. spring delay, slider/pendulum mechanism):
-. First ejection: Usually ejecting the main part or separating the product from the core.
-. Short delay/transition: key mechanism action, ready for secondary ejection.
-. Second ejection: ejection of the remaining part (such as the inverted area) or complete release of the product.
2. Key components and characteristics:
- Precision ejector pin/ejector block: high quality die steel (e.g. SKD 61, H 13, etc.), heat treated (hardness HRC 52-56 +), high wear resistance and corrosion resistance. A variety of diameters/shapes are available.
-Ejector plate system: high rigidity design, including primary ejector plate and secondary ejector plate. Precision machining ensures parallelism and guiding accuracy.
3.Different install methods, different function. This ZZ4 series latch locks with wide applicability which can be used as two-satge ejector, latch lock

Product Application Scenario

Widely used in complex plastic products requiring stepwise demoulding:
1. Automobile parts: inner core of door handle, complex buckle, shell with inner rib and lampshade parts.
2. Electronic and electrical appliances: connector (with inverted terminal), thin-wall shell, cooling fan impeller, precision gear.
3. Medical equipment: syringe push rod, precision tube, diagnostic equipment components with internal structure.
4. Household appliances: buttons with internal buckles, complex grids, deep chamber containers (such as inner tub parts of washing machines). 

5. Packaging: thin-walled containers with incised lids or complicated opening structures.
6. Any application where there is a deep cavity, internal back-off, or the product is sensitive to ejection force.
