Guide to plastic injection moulding

Plastic Injection Molding is a method of mass-producing parts and products. It is also one of the preferred methods for manufacturing parts because it has multiple advantages over other methods of plastic moulding. Plastic injection moulding is also extremely efficient, simpler and more reliable. You should have no doubts about using this method to manufacture parts in large quantities.

Few major advantages of using injection moulding for manufacturing plastic parts and components.

1. Detailed Features and Complex Designs

The injection moulds are subjected to extremely high mechanical pressure during the process of Injection Molding. As a result, the injected plastic material within the moulds is pressed harder against the mould compared to any other moulding process. Due to this excessively high pressure, it is possible to add a large number of details into the design of the part requiring complex and intricate shapes.

2. Highly Efficient Process

Every injection mould is specifically designed to the customer’s specifications and the Injection moulding machines are pre-programmed for production, the actual moulding process is very quick compared to other methods of moulding. Plastic injection moulding process hardly takes times and this allows more parts to be manufactured from a single mould. The high production output rate makes plastic injection moulding more cost-effective and efficient.

3. Enhanced Physical and Mechanical properties.

In the plastic injection moulding process, it is possible to use fillers along with the Thermoplastic materials. These fillers reduce the density of the plastic while it is moulded and also help in adding greater strength to the part after it has been moulded. In fields where parts need to be strong and durable, plastic injection has an option that other moulding processes do not offer.

4. Automation to Save Manufacturing Costs

Plastic injection molding is an automated process. A majority of the injection molding process is performed by machines and robotics which a sole operator can control and manage the processes. Automation helps to reduce manufacturing costs, as the overheads are significantly reduced. Furthermore, with reduced labour force the overall cost of manufacturing the parts is reduced and this cost-saving can easily be passed on to the customer.

Advantages of Plastic Injection Moulding

Using the Plastic injection molding method , it ensures the parts manufactured hardly require any work after the production. This is because the parts have more or less a finished appearance after they are ejected from the injection moulds.

The scrap plastic generated during the production process is reground and re-used. Hence, the process generates very little waste, hence this is a very environment-friendly process.
