Plate Movement Product Sizing For Mold Tooling

The geometry of planned injection molded component defines the complexity and the amount of work involved in designing and producing the molding tool. At the design phase, one should look closely at the practicality of the molding tool and the complexity of the demolding process.

Hasco America Inc., with its comprehensive range of latch locking units and two-stage ejectors, offers a variety of solutions specifically for the field of multi-stage demolding. Compared to latch locking units, which precisely control the movements of the mold plates by opening the mold, two-stage ejectors control the sequence of the ejection by splitting up the output movement into separate stages.

To simplify selection for users and provide help with the design, to make choosing demolding easier, a brochure entitled "Multi-stage Demoulding" is now available both online and in print.

The main focus when choosing the right demolding unit is on desired movements and respective mounting positioning. Some movement examples are: forward and backward movements, single stroke and the use of stripper plates. The product selection can then be narrowed down according to the requirement of how the plates should move in relation to each other.

Next, the mounting position necessitates renewed filtering of the selection. A distinction is made between central and off center mounting and between internal and external mounting of the standard units. Then the right standard unit can be ordered, depending on the mold size and the desired length of the stroke movements.

All products can be easily and reliably mounted and adjusted. The precisely manufactured standard units for multi-stage cycles are coated on the functional surfaces with Hasco's DLC coating and thus have hard sliding surfaces and a low coefficient of friction. This creates the basis for consistent component quality, even when used in clean rooms.
