Cost Effectiveness – VDI finishing requires less tooling and processing, helping to reduce production costs.
Limitations of VDI Surface Finishes
Less refined appearance compared to SPI coatings VDI finishes are less reflective and polished and appear more textured and matte.
Limited variety of texture options available compared to SPI finishes.Injection molding involves a mass production process of manufacturing plastic parts. Their production is done by injecting a molten material into a mold cavity. This process involves many molded parts with complex structures such as undercuts and intricate designs. Demolding these parts can be very challenging, and this is where mold lifters become necessary. These are essential components that facilitate the safe ejection of molds from the cavity, thereby improving part quality and overall manufacturing efficiency. The common components of mold lifters are the lift rods, guide pins, and the lifting mechanism. Another important component involved in part ejection is the mold slider . While they both allow movement within the molds, they each have unique qualities that make them ideal for particular applications.

The main benefit of a mold lifter is that it helps improve fan database the efficiency of manufacturing processes. They automate the part removal process, which significantly reduces runtime and increases throughput without sacrificing product quality. This not only saves time, but also improves workplace safety. Accurate and consistent part ejection reduces the risk of damage and ensures that each component meets requirements. This allows engineers and producers to design innovative products with complex features, textures, and shapes that meet the highest industry standards.

The purpose of this article is to focus on specific aspects of mold lifters, such as design, selection, and drawbacks. Ultimately, this will enable our readers to make informed decisions regarding the implementation of mold lifters.

What is a mold lifter?
A mold lifter is a specialized mechanical component used in injection molding and die casting. It helps lift and eject molded parts from the mold cavity after the cooling process is complete. It helps address the challenge of removing products with complex geometries, such as wires. It is a mechanism that facilitates lateral or right-angle movement in addition to vertical movement of the mold. It typically includes a mold lift rod and a mechanism that facilitates lateral or angular movement in addition to vertical movement of the mold.

Elevator animation
A mold lifter is located in a positioning block, in an inclined position. When activated from below, it moves a short predetermined distance in the direction of its inclination. Since there is space on top in this direction to allow removal of the finished product, the product moves vertically when the ejection process begins. Simultaneously, the elevator moves in the direction away from the mold, to facilitate demolding. This action allows parts to be lifted or moved from the mold cavity without effort. Without an elevator, the ejection process would be considerably more difficult, if not impossible.
