A Beginner’s Guide to Foam Moulding: What it Is and How it Can Work for You

Injection moulding is one of the industrial methods for creating various parts be it for machinery or anything else. The process involves creating structures from a mould by injecting a stream of molten substance into it and then allowing it to settle down. It is one of the most common types of moulding and is very widely used. 

There are other types of injection moulding, foam moulding being one of them. This type of moulding is mostly used for making parts such as roofs of vehicles which have unprecedented sizes yet needs to be light and hard. The process of foam moulding is slightly different from its counterpart.

What Is the Foam Moulding Process?

While injecting the molten substance into the mould, an inert gas is injected with it. Gas because it has to create a froth. Inert gases are selected because such substances do not hamper the other chemical reactions that are to occur. Due to the injection of the gases, the material forms a sandwiched like structure with a light foamy core. The molten substance settles on the outer side giving it a tough and rigid exterior. The foamy core is responsible for the lightweight nature and low density of the material.

Benefits of Foam Moulding

Why would someone go for foam moulding? There are numerous advantages that this particular technique has. Due to these advantages, the popularity of foam moulds is growing. Many sectors have a dire need for such materials.

• The material is very sturdy and not deformed easily. The tough exterior that settles on the mould provides it with the right amount of tangible strength that it requires. 

• Due to its process of manufacturing, you get the option of customising the thickness of the walls depending on your requirements.

• Foam moulding provides greater liberty in terms of designing the parts. The sizes of the units produced are better suited for production in different sizes as compared to the other methods.

How Much Would it Cost?

This is one of the important factors to be considered when going for foam moulding. There are several parameters to be considered for that answer. Any agency that you may go to would judge your budget mostly on the following:

• Type and features of your product

• Dimensions of the product

• The amount in which they need to be produced

• The material you will be using

• Additional techniques required for production

• Assembling the parts and their logistics

Do Your Homework Before Making a Decision

It is always wise to do a quick analysis yourself before bringing it up to a firm to ensure you are in a better-informed position. Weigh out your options carefully before settling for anyone. Many sites offer consulting services for the same. Clear your uncertainties before you proceed so that you only choose the best for your firm.
