Mold making is the procedure of generating molds for forming metals, plastics, rubber, glass or ceramics in to shapes.
Molds are negative spaces that serve as a model or pattern for shaping heated raw material such as plastic, metal, glass, ceramic, or other. Molten material is heated and poured. The liquid hardens and takes the shape of the hollow shape which is then removed. Thus, molding is a process of manufacturing a variety of objects in a specific shape of size. Molds are used for metal casting also. Molding can be done in a variety of methods. Here are some types of molding application that are adopted by the manufacturers
Types of molding include:
Blow Molding: Blow molding is a process through which hollow plastic parts are formed. The process starts with melting plastic pellets and forming them into a parison. The parison is a plastic having a hole in one end that is compressed so that air can pass through. There are three types: extrusion blow molding, injection blow molding, and stretch blow molding.
Compaction plus sintering: Conventionally, the process is used for molding ceramic objects and other products using compressed powder. The entire process is based on the atomic diffusion, in which, the powdered material is heated to a temperature below the melting point.
Compression Molding: It is a process of molding in which the molding material is first preheated and then kept in the open and heated like a mold cavity. The process is applied on thermostatic plastic compounds.
Extrusion Molding: Extrusion is a process through which a fixed cross-sectional profile can be created. Using this process helps in creating very intricate work. Extruded materials can be polymers, metals, ceramic, foodstuff, concrete, and more.
Injection Molding: This process is ideal for developing parts from thermosetting plastic and thermoplastic materials. The treated material can be aluminium and steel for making body panels of cars, and more.
Laminating: Unifying two or more materials is called laminating and the process adopted is known as lamination. The treated material can be wood, plastic, and more.
Reaction injection molding is a part and parcel of laminating in which the thermosetting polymers are used. Components made through this process are air spoilers, automotive bumpers, and fenders.
Matrix Molding: The process is utilized to shape complex materials such as with glass, ceramic or glass composites. The process is also known as matrix transfer molding.
Rotational Molding (or Rotomolding): This process is also known as rotocasting, rotomolding, or spin casting that is implied to create a vast range of hollow items of plastic.
Transfer Molding: This process is very similar to compression molding which is ideal for thermo set plastic.
Thermoforming: In this method, a plastic sheet is heated to a pliable developing temperature to form a mold and then trimmed to get the right shape of an object. The process is adopted to manufacture containers, disposable cups, clamshells, lids, trays, blisters, and other products for the medical, food, and general retail industries.
