The Features of jar preform mould
Jan 29,2023
A jar preform mould is a type of mould used in the manufacturing of jars. It is typically made from steel or aluminum and is used in the injection moulding process to shape the preform, which is then heated and blown into its final shape. The preform mould can be designed to produce jars of various sizes and shapes, and can include features such as threads for lids or handles. The design and production of a jar preform mould requires precision and expertise in order to create a high-quality end product.
Some common features of a jar preform mould include:
1.Multi-cavity design: This allows for multiple jars to be produced at the same time, increasing productivity.
2.Interchangeable cores: This allows for the production of jars with different neck finishes, such as screw-on or snap-on lids, without having to change the entire mould.
3.Cooling systems: A well-designed cooling system ensures that the preforms cool quickly and evenly, reducing the risk of warping or deformation.
4.Precision alignment: The mould must be designed with precision to ensure that the preforms are formed with accurate dimensions, good surface finish and minimal flash.
5.Durability: Jar preform moulds are subjected to high temperatures and pressure during the injection moulding process, so they need to be made from durable materials that can withstand the rigors of continuous use.
6.Easy maintenance and repair: The mold need to be designed for easy maintenance, and it should be easy to replace or repair any parts that wear out over time.
