Injection moulding is one of the key processes for producing plastic articles. It is a quick process and is used to create huge numbers of identical items from high precision engineering components to disposable consumer goods. Injection mouldings count up a significant proportion of all plastics products from micro parts to large components. Practically all sectors of manufacturers use injection moulded parts. The flexibility in shape and size possible through use of this process has constantly extended the margins of design in plastics and enabled significant replacement of traditional materials.
The basic injection mold making process is as follows:
- Products design department provides product information to the injection mold design department, injection mold designers complete cost analysis and provide it to the manager.
Plastic injection molding is a methodology that impels liquid plastic into a specific mold to make fully customized things like name plates, plaques, different types of signs and products related to branding elements. Once the plastic gets completely cooled, it is released from the mold to create an array of plastic parts for different types of purposes and industries.
The most popular use of injection mold equipment is made in:
- Name plates of appliances
- Name plates for industrial equipments
- Branding and the license plates of the vehicles
- Emblems of the cars
- Recreational products and product identification
A recent survey projected that the global plastics industry has witnessed a continuous shift of production bases to low-cost Asian countries. With increasing foreign investment and rise in the number of new manufacturing establishments in the region, Asia has become the largest and the fastest growing market for plastics in the world.
In particular, India has turned out to be a fertile ground for the packaging sector representing almost 60.0% that is expected to reach 10.0 million tonnes by 2020. On this score, China has posed quite a tough challenge. This is the scenario for the FMCG sector whose products solely rely on plastic based packaging of PET (polyethylene terephthalate) technology.
These trends have been a boon for plastic mold manufacturer since PET bottles, jars and allied containers with higher shelf value and attractive features have literally replaced glass and other materials. In this context, the user of the packaging facilities has to rely on a reliable and reputed manufacturer of molds such as the New Delhi-based Acme Dysis for solutions on a turnkey basis.
There are many conspicuous examples of moulds in our daily life. Have you ever wondered that how various objects around us acquire their shape? The answer to this is injection Molding (IM). The idea was conceived in 1930s and gained popularity when manufacturing plastic commodities led to greater scrap wastes and extended production time while devising alternative manufacturing technique.
Difference between injection molding and conventional metal die casting
The basic difference between injection molding molds and metal die casting is that the latter requires molten material (metal) to be poured in the casting; however, the former needs the melted plastic residuals to be injected forcefully into the mold.
What kind of plastic is suitable for molding machines?
The notion of using ‘any kind’ of plastic for getting the desired shape is gravely wrong. Thermostat plastics such as nylon, polystyrene, polythene and polypropylene are ideal for IM technique. Continue reading
