The Molding process is used to manufacture various items by shaping the liquid or pliable raw material with the use of a rigid frame which is called a mold or a matrix.
A Mold or a matrix is a hollow block which has to be filled with the liquid or pliable materials such as the Plastic, metal, Glass, or even Ceramic Raw Materials. The material i.e. the liquid hardens inside the mold, and thus creating the specified shape. The very commonly used method is the bi-valve process, which uses two molds, of which each one produces half of the object.
The molding process is used in making many plastic products such as the Cups and Bowls. We see such molds are used for various purposes, and the cups and bowls are used for serving solid as well as liquid consumable products. In the Market we are able to see many products which are available in the bowl shaped materials, which are mostly ready to cook or eat, and such kinds of packed materials are called the Point of Purchase Products.
The relatively deep parts can be formed by mechanically or pneumatically stretching the formable sheet prior of bringing it into contact with the surface of the mold and applying of vacuum pressure.
The most suitable materials for the use in vacuum thermoforming are conventionally the Thermoplastics. The High Impact Polystyrene Sheeting is the most common and the easiest to use thermoplastic. The thermoplastic is molded around an aluminum or wooden mold, which is capable of forming almost any kind of shape. It is also suitable for creating transparent molds of acrylic material, which are used widely in applications such as aerospace, like the passenger cabin windows. The vacuum thermoformed components are used in place of the complex fabricated metal sheets, fiberglass, or even plastic injection molding.
The Yiyou Thermoforming machine Manufacturers manufactures machine which are Fully-automatic and Semi-automatic, which are capable of providing the most precise and accurate work.
