Thermoforming Materials: Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. There is a wide range of thermoforming materials that provide just the right properties for your plastic formed product, and each material has physical characteristics that make it suitable

What are Plastics? Plastics are a material that is made up mainly of macromolecules, that can be made fluid by the action of heating and pressurizing, and that can be processed into end products with any useful shape you want to make. Classification of Plastics Plastics can be classified into: 1. Thermoplastics and Thermo sets 2. Amorphous Thermoplastics and Crystalline

Interpolation The method by which contouring machine tools move from one programmed point to the next is called interpolation. This ability to merge individual axis points into a predefined tool path is built into most of today’s MCUs. There are five methods of interpolation: linear circular helical parabolic cubic All contouring controls provide linear interpolation, and most controls are capable

Two types of programming modes, the incremental system and the absolute system, are used for CNC. Both systems have applications in CNC programming, and no system is either right or wrong all the time. Most controls on machine tools today are capable of handling either incremental or absolute programming.   Incremental program locations are always given as the distance and

The term numerical control is a widely accepted and commonly used term in the machine tool industry. Numerical control (NC) enables an operator to communicate with machine tools through a series of numbers and symbols. NC which quickly became Computer Numerical Control (CNC) has brought tremendous changes to the metalworking industry. New machine tools in CNC have enabled industry to

HEAT TREATMENT The strength toughness of the base material are determined by its chemical composition and the heat treatment it undergoes. Low carbon steel is easily available and cheap having all material properties that are acceptable for many applications. Low carbon steel contains carbon contain of 0.15% to 0.45%. Heat treatment on low carbon steel is to increase ductility, to

Thermo plastics These kinds of plastics have long separate and large molecules arranged side by side. The various types of thermoplastics are discussed below. Cellulose derivatives Cellulose nitrate is generally obtained by treating the cellulose with a mixture of nitric acid and sulphuric acid. It has high toughness, good resistance to moisture and it is highly inflammable. It is mostly

Thermosetting Plastics The plastic which are hardened by the heating is called as thermo setting plastic. this heating reaction is non-reversible. The molecules of this type of plastic have a very strong binding force. The raw material for these kinds of plastics is available in liquid or solid form. These types of plastics consume more time for polymerization Phenol formaldehyde
