  In the age of programming, CNC machines are a boon to manufacturing units. CNC stands for computer numeric control. A CNC machine is operated and controlled entirely through software. History and Evolution of CNC machines It all began in the 1940s, right after the World War II. The earliest version of CNC machines developed during that time basically numerically controlled or NC machines. Initially the fabrication and the manufacturing process was carried on by numerically controlled machine before the invention of CNC machines. These NC machines were created by John T Parsons. In 1960s and early 1970s the idea of computer-controlled machines began to circulate. By 1989 CNC machines became the industry standard. The initial machines had punch cards with G codes. As these machines were hardwired it was difficult or rather impossible to change the pre-set parameters. The G-codes in the modern CNC machines are designed and controlled by computers. The whole set up allows you to do r...

  What is plastic? It is a type of material that contains an essential ingredient of an organic medium having a large amount of molecular weight. These organic mediums are either naturally occurring or synthetic in nature. Plastics are also defined as polymers that have long carbon chains. The word Polymer is derived from the two Greek words, poly that is many or abundance, and monomer that is a single unit. Plastic was discovered by the German chemist Christian Schonbein, in 1846. The word plastic is also derived from the Greek word, Plastikos which is to mould. Important properties of plastic are- Plastics are extremely strong and ductile and they are poor conductors of heat and electricity. They can be designed into the desired shapes and sizes according to the product. They have properties to withstand corrosion and are also resistant to many chemicals. They are also used in the construction sector as they have low maintenance and a high level of durability. It makes for one of...

Moulding is the process of shaping liquid or soft raw materials by using a fixed frame called a mould or a matrix. The mould is made of a metal container where liquid, plastic, metal, ceramic, or glass is poured. The goal is to create multiple uniform copies of the product as the final product.   The liquid cools down and takes the shape of the mould or the container. The product is removed by using release agents or ejection pins. A product can be moulded in different ways. The different types of moulding methods of:   Injection Moulding Injection moulding is a manufacturing process in which molten material is injected into a mould.   A lot of materials can be used for injecting. For example, metals, glass, elastomers, confections, thermoplastic and thermosetting polymers. The material is placed in a heated barrel, mixed using a helical screw, and injected into a mould cavity. This material is cooled and hardened to the shape of the cavity. Blow Moulding Stre...

  Far from being a process or just a trend, additive manufacturing is more of a technological revolution that comes under the fourth industrial revolution. As the name suggests, the additive manufacturing process works by adding materials. Layers upon layers of materials are deposited successively on top of each other until the desired object is produced. What is additive manufacturing? Additive manufacturing (AM) is the industrial manufacturing process that uses computer-aided-design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, to create desired geometric shapes. How does additive manufacturing work? The very first step in additive manufacturing is to create a 3D model of the object. This model can be designed using computer-aided design (CAD) software. This CAD file is now converted to a standard additive manufacturing file format, which is usually an STL file. The STL file is then digitally sliced into different layers. The third...

PET, an acronym for polyethylene terephthalate, is a synthetic resin of thermoplastic polymer, while a preform is an intermediate product that is ultimately blown up into containers or bottles. Preforms are manufactured from polyethylene terephthalate (PET), and so they are called "PET Preforms." Over centuries, PET preform moulds have been manufactured in a particular manner. However, with modern plastic moulding materials, there has been a great advancement in the way they are manufactured now. The most recent mass production PET preform moulding machinery has been developed, and the latest PET preform moulds in steel and alloys have been introduced to withstand severe processes. Accuracy is the key requirement in present manufacturing, and PET preform plastics are manufactured by steadily mounting a high standard of precision, which requires modern machine tool applications and methods. While there are several PET blow mould manufacturers and suppliers all over the globe...

Lean manufacturing is a method for eliminating or reducing waste from the manufacturing process. Introduced by Toyota in the year 1930, the term “lean’ was first coined in 1988. Lean manufacturing has since become standard practice in every industry. In recent years, many manufacturing processes have been adopting a lean method for greater efficacy, efficiency, and profitability. But what do you mean by lean manufacturing? And why is it so important? What is Lean Manufacturing? Lean manufacturing is a continual process of minimizing waste and maximizing productivity within a manufacturing operation. Waste is anything that uses resources without adding value to what the customers will pay for. Waste in industry processes, whether poor processes, idle workers, or unused supplies, is a drain on throughout, and lean manufacturing aims to remove all these. What are the Five Principles of Lean Manufacturing?  Lean manufacturing is built of five core principles for improving e...

Are you into building products that involve moulded plastic parts? Blow moulding and injection moulding are the two most common ways to produce cost-effective, high-quality plastic parts and derivatives; however, both serve different purposes and have different requirements. So, which one is right for you? To know which one better suits your purpose, first, you need to know the primary difference between them. Determining if blow moulding or injection moulding is suitable for you begins with understanding the basics. Here’s a quick guide on blow moulding and injection moulding, their differences and their applications. 1)       Different Products Perhaps the most obvious difference between parts made by blow moulding and parts made by injection moulding is that blow moulding creates hollow parts, while injection moulding produces solid parts. If you’re producing a piece that can be structural, flexible or hold fluid, blow moulding is what you need.   ...
