Injection Moulding & technology
- 2. What is Moulding process? Molding or moulding is the process of manufacturing by shaping liquid or plastic raw material using a rigid frame called a mold or matrix into desired shape.
- 3. Types of Plastic Moulding There are 5 types of plastic moulding that is considered to be the most effective and most popular. Injection moulding Extrusion moulding Compression moulding Blow moulding Rotational moulding.
- 4. What is Injection Moulding Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars
- 5. Types Of Injection Molding Technology Thin Wall Molding. Gas-assisted Injection Molding Metal Injection Molding(Insert molding) Liquid Silicone Injection Molding. 3D Printing.
- 6. Thin Wall Molding Thin wall injection molding is a specialized form of conventional injection molding that focuses on mass-producing plastic parts that are thin and light so that material cost savings can be made and cycle times can be as short as possible. Shorter cycle times means higher productivity and lower costs per part The size of a part puts a limit on how thin the wall thickness can be. For packaging containers thin wall means wall thicknesses that are less than 0.025 inch (0.62mm) with a flow length to wall thickness greater than 200For Example food packaging ( e.g. food containers and lids) ,automotive (e.g. both structural and non-structural car parts), mobile telecommunications (e.g. mobile phone housings) medical (e.g. syringes), computing equipment
- 7. Gas-assisted injection Molding It is a molding process where an inert gas is introduced at pressure, pushing the plastic melts into the mold extremities at the end of the polymer injection phase.
- 8. Metal Injection Molding Metal injection molding (MIM) is a metal working process in which finely-powdered metal is mixed with binder material to create a "feedstock" that is then shaped and solidified using injection molding. The molding process allows high volume, complex parts to be shaped in a single step.
- 9. Liquid Silicone Injection Molding Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume, Low chance of contamination, Quick cycle time
- 10. 3D printing 3D printing, also known as additive manufacturing, is a process by which physical objects are created by depositing materials in layers based on a digital model.
- 11. Materials used in injection Moulding Nylon (Polyamide) Polycarbonate. Polycarbonate compact discs are very durable, Polyoxymethylene (POM) ,Polystyrene (PS)Acrylonitrile Butadiene Styrene (ABS) , Polypropylene (PP), Polyethylene (PE)
