What is 2-Shot Moulding?

One of the biggest reasons plastic injection moulding is such a widely used process is its versatility.

2-shot moulding is a process that allows products to be produced using multiple materials and colours, at the same time.

In this blog, we’ll explore the 2-shot process in more detail, list its benefits and why it might be the choice for you…

2-Shot Moulding

Under the general umbrella of plastic injection moulding sit a variety of sub-processes.

Also known as multi-shot, double-shot, or dual-shot, 2-shot moulding is one of them.

2-shot moulding allows manufacturers to produce one complete product comprised of multiple materials and colours.

How does it work?

Initially, the first material is injected into a mould to create a base that has spaces for the second material to fill.

Once this base is cooled, it’s then transferred to another chamber where the second material is injected onto the base, forming a smooth and durable connection.

The two materials used need to be chemically compatible, as otherwise the bond won’t form correctly, causing structural flaws.

What are the benefits?

2-shot moulding has multiple benefits, some of which are:

  • it’s cost-effective,

  • it can save production time,

  • it’s versatile,

  • it can accommodate complex designs,

  • it provides more design options.

With 2-shot moulding, you’ll be able to produce a more aesthetically pleasing and durable product, perhaps with multiple colours.

Complex designs can be produced with ease in one cycle and with a very low margin of error, saving you time and money.
