Vents: the size, location, and number of vents in the mould should be designed to allow the air and gas to escape from the mould cavity and to prevent the formation of voids, bubbles, or burns. For example, a vent may be located at the end of the flow path or at the thinnest section of the product.
Cooling: the layout, size, and number of cooling channels in the mould should be designed to provide uniform and efficient cooling to the mould and the product and to reduce the cycle time, energy consumption, and defects. For example, a cooling channel may be straight, spiral, or conformal, depending on the mould shape, size, and material.
Ejection: the type, size, location, and number of ejector pins, plates, or sleeves in the mould should be designed to facilitate the removal of the product from the mould cavity and to prevent damage or deformation of the product. For example, an ejector pin may be round, square, or blade-type, depending on the product shape, size, and material.
Enhancing product features: by designing and selecting the mould according to the product specifications, such as shape, size, weight, strength, appearance, and function, you can enhance the product features and meet the customer expectations and requirements.
Reducing waste: by designing and selecting the mould to minimize the material usage, the injection pressure, the cycle time, and the rework, you can reduce material waste, energy waste, and cost waste.
