The process of casting is a core manufacturing process whereby molten material is poured into the mold cavity to obtain complex shapes and component fabrications. The book is a thorough explanation of the ten primary types of casting most others you’ll hear or read about; all the way down to that familiar sand casting most people are used to, to the new and intriguing squeeze casting with its extensive possibilities. You will need to know them whether in the automotive industry, aerospace industry, medical device manufacturing or even machining as you will be in a position to know exactly which casting process will best suit your needs taking into consideration the issue of costs, accuracy, finish and volume of your job.

CNC machine components: Any CNC machine part is largely subjected to precision threads in mechanical connection and power transmission, such as straight, tapered, fastening, and power transmission in profiles threads are applied upon specific applications in automotive, medical, aerospace, and industrial. Knowledge in thread terminology, standards (UTS, Metric, Acme, Buttress, Square) and manufacturing processes is fundamental in the manufacture of high quality components with international tolerance specifications of +/- 0.001mm and tolerance requirements as regards to surface finishes when used in precision demanding applications such as connector molds to semiconductor packaging equipment.

Wire EDM (Electrical Discharge Machining) is a high precision manufacturing process that works using electrical sparks to cut through conductive materials with a very high degree of accuracy. This detailed guide discusses the technology, uses, benefits and factors to put into consideration when utilizing wire EDM in the contemporary manufacturing processes.

The injection molding tolerance is a very important specification applicable in achieving tolerance and accuracy of dimensions of fabricated items. This is an extensive overview of standard tolerances, factors to consider, design and best practices to apply when pursuing tight tolerance in injection moulding. These principles are vital to the manufacturers that desire to produce quality components that satisfy high quality demands in the industry.

Tolerance stack-up analysis constitutes a core engineering practice that guarantees precision mold components satisfy their functional requirements while minimizing manufacturing costs. When manufacturers grasp both worst-case and statistical analysis techniques, they can make well-informed choices regarding tolerance allocation and the associated manufacturing processes. The critical step is choosing the most suitable analysis method in accordance with the application’s demands, the manufacturer’s capabilities, and the budgetary constraints.

CNC (Computer Numerical Control) machines are the pinnacle of the modern precision manufacturing business which is made up of the highly advanced components working together to develop the highly accurate components. The small detail of the machine frame down to complex feedback systems all play a vital part in attaining the close tolerances and high end product quality that is required by the automotive, medical and semiconductor packaging industries. A compatible knowledge of these constituents is vital to the manufacturers who desire to streamline their production procedures and do not want to lose their market competencies in precision manufacturing.

CNC machining tolerances CNC machining tolerances specify acceptable variation between parts produced and are key towards proper fit, function and assembly. Normal tolerances are nominal +0.005″ or less and -0.005″ or less for general machining work, and +0.001″ or less and -0.001″ or less under scientific machining. Tighter limits are possible when such are functionally necessary. The key to success is also balancing between the functional requirements and manufacturing capabilities with the help of proper tolerancing approaches coupled with the use of effective quality control mechanisms. The use of strategic tolerance specifications, i.e. only using tight tolerances where required, offers best-in-class part performance and manufacturing cost through the best possible process design and characterization.

Knowledge of the 3D printer file formats is essential in the successful additive manufacturing project. This is a full tutorial on the most popular file formats in 3D printing, including STL, OBJ, Swiss cheese AMF, and polycos 3MF formats. With the precision mold components you would like to prototype or with the complex geometries you would like to make, it is important to select a file format that originally influences the quality of the print as well as compatibility and efficiency of the manufacturing process. Get to know how to choose the best format to use in your particular application and find out the major differences among different 3D printing file formats.

CNC milling machines and routers have distinct needs of manufacturing where milling machines have an added advantage of precision (tolerance is + / -0.001mm) in cutting metals and hard materials and routers being fast in the preparation of softer materials such as wood and plastics. Milling machines are rigid in construction with high precision spindles suited to precision mold parts and connector work rather than large work volumes and quick material removal as seen on routers to provide sheet work. The selection is material specific, involving precision or scale of production and overall milling machines are considered where strict precision is required and routers are used in large scale machining in softer materials.
