Injection mould design is the process of developing a moulding tool that can reliably produce plastic components with the required geometry, dimensional accuracy, surface finish, and production efficiency. A well-designed injection mould must account for the part design, plastic material, injection process, cooling requirements, ejection, moulding machine, and expected production volume. An injection mould generally […]

Undercuts in thermoforming moulds are features that prevent a formed plastic component from being removed directly from a conventional mould along the normal direction of mould opening. They may occur as recesses, projections, hooks, grooves, or other geometrical features that lock the formed part onto the mould. Undercuts can provide useful functional features in thermoformed

Semi-positive compression moulds are a type of compression moulding tool that combines features of positive and flash-type compression moulds. They use a relatively close-fitting punch and cavity to control the flow of moulding material while still allowing a limited amount of excess material to escape through a controlled clearance or flash area. During the moulding

Interchangeable insert moulds are injection moulding tools designed with replaceable cavity, core, or other mould inserts that can be removed and exchanged without replacing the complete mould. This modular approach allows a single mould base to be used for producing different components, product variants, or design configurations. The interchangeable inserts are accurately located and secured

Parting line design is an important aspect of thermoforming mould development that determines the location where the mould separates to release the formed plastic component. The parting line is the boundary between the mating sections of a mould, typically the upper and lower mould halves. Proper parting line placement helps ensure easy demoulding, accurate component

Positive compression moulds are a type of compression moulding tool designed with a closely fitting punch and cavity to produce components with precise dimensions, controlled material thickness, and minimal flash. In this moulding process, a measured quantity of moulding material is placed into the mould cavity, and the punch applies direct compression to force the

Family injection moulds are specialized injection moulding tools designed to produce multiple different plastic components within a single mould during one injection cycle. Unlike conventional multi-cavity moulds, which produce identical components in every cavity, family moulds contain cavities of different shapes and sizes to manufacture related components simultaneously. In a family injection mould, multiple cavities

Draft angles in thermoforming moulds are the slight tapers incorporated into the vertical walls and surfaces of a mould to facilitate the easy removal of thermoformed plastic components without causing deformation, surface damage, or excessive friction. These angles are an essential part of mould design, as they help ensure smooth demoulding, maintain dimensional accuracy, and

Flash-type compression moulds are a conventional type of compression moulding tool designed to manufacture plastic, rubber, and thermoset components by applying heat and pressure to a measured quantity of material inside a mould cavity. In this moulding process, a controlled amount of excess material is allowed to flow out through the clearance between the mould

Stack moulds are advanced injection moulding systems designed to increase production capacity by incorporating two or more parting lines and sets of mould cavities within a single mould assembly. This configuration allows multiple layers of components to be produced during a single injection cycle, significantly increasing output without requiring a larger injection moulding machine. In
