What Are the Classifications of Injection Mould Tooling?

Introduction: 

Injection mould tooling, also known as an injection mould or die, is a          custom-engineered mold that gives plastic parts their shape in the injection molding process. The tooling is made up of two primary components - the cavity side and the core side. Injection mold tooling refers to the construction of molds used in the injection molding process. These molds can vary in complexity and design, depending on the specific requirements of the production process. As a leading Houseware Moulds Manufacturer in Ahmedabad. In this blog, we will delve into the classifications of injection mold tooling, exploring various types and their applications.

Single-face injection mold tooling:
Single-face injection mold tooling is the simplest form of mold construction. It consists of a single cavity or impression that produces one part per cycle. This type of mold is typically used for low-volume production or for parts that do not require complex features or multiple cavities.

Double-face injection mold tooling:
Double-face injection mold tooling, also known as two-cavity mold tooling, features two mirror-image cavities on the mold. This allows for the production of two identical parts per cycle, effectively doubling the output compared to single-face tooling. It is commonly used when higher production volumes are required.

Injection mold tooling with side parting and core pulling mechanism:
This type of mold tooling involves a side parting line, where the mold splits into two halves. The core pulling mechanism is employed to create undercuts or complex features on the part that would otherwise be impossible to release from the mold. It is often used for parts with intricate shapes or those requiring internal threads or other complex geometries.

Injection mold tooling with movable mold parts:
Movable mold parts refer to sections of the mold that can be shifted or rotated during the injection molding process. These parts help create features such as hinges, living hinges, or movable components within the final product. They offer increased design flexibility and are commonly used in applications such as automotive interiors, consumer electronics, and medical devices.

Automatic unscrewing injection mold tooling:
Automatic unscrewing mold tooling is designed for producing threaded parts. It incorporates a mechanism that allows the mold to rotate and unscrew the threaded portion of the part once it has solidified. This type of mold tooling is commonly used in industries such as automotive, electrical connectors, and closure systems.

Runnerless injection mold tooling:
Runnerless injection mold tooling, also known as hot runner mold tooling, eliminates the need for runners, which are the channels that deliver molten plastic to the cavities. Instead, a heated manifold system is used to directly inject the plastic into the cavities, reducing material waste and improving cycle times. This type of tooling is particularly suitable for high-volume production runs

Right-angle injection mold tooling:
Right-angle injection mold tooling is employed when the part design requires a change in the direction of the flow path within the mold. The mold is designed with internal channels or passages to guide the plastic material through the desired path. This type of mold tooling is commonly used for parts with intricate geometries or those that require specific filling patterns.

Injection mold tooling with demolding mechanism on the fixed mold:
In this type of mold tooling, the demolding mechanism is integrated into the fixed half of the mold. This allows for easier ejection of the part after it solidifies. It is often used for parts with complex shapes, high aspect ratios, or those that require precise demolding to prevent damage.

Conclusion:

Injection mold tooling can be categorized in several key ways that impact the molding process. The main classifications are by the number of cavities, the type of gate, the mold material, and whether the tool is built for prototype or production. Analyzing the advantages and tradeoffs of each tooling type and class allows mold designers and manufacturers to select the best option for their specific molding needs. 

With knowledge of the capabilities and limitations of each tooling classification, manufacturers can plan out an effective molded parts strategy. Partnering with an experienced injection molding R.D.
