Toolcraft Plastics - Moulding Your Ideas

Add a touch of sparkle to your products !

We admit, many of the moulding projects we're involved in are black or white. But if you want to add some colour to your next project, here's our guide to what's available.

Colour compounding

With colour compounding, the material supplier mixes the colour with the base material when it is being made and delivers the plastic granules to us ready-coloured. Materials can be matched to your company colours. This method results in the most consistent colouring run after run and is sometimes the only way to colour materials with a dense base colour such as fire retardant ABS. Compounding is most suitable for long run products as small quantities of the material are expensive and sometimes not obtainable. At Toolcraft however, we're able to obtain just one bag of colour compounded material, making this method possible for short runs too.

Masterbatch

When we use masterbatch colours, the masterbatch dye is added to the base material on-site.

It can be more difficult to get good colour consistency with masterbatch than with compounding, but at Toolcraft we ensure colour consistency by using electronic dye dosers on our injection moulding machines. We can get masterbatch mixed especially to your company colours. We can also make your mouldings from a range of 200 or so standard colours - as we can buy them in quantities as low as 250g, we can make small batches of coloured mouldings for you quickly and cost effectively.

A touch of sparkle

By adding aluminum impregnated dies to a base material, we can achieve a sparkling finish on components, like this cosmetics container.*

Other special effects available are pearlescent, fluorescent and metallic, all achievable economically by using masterbatch.

* It's not a cosmetics container, but as this is a daytime e-mail, I can't tell you what it really is.

Toolcraft tip: Factors that affect colour

If your product has a textured surface, the colour really can look significantly different from that of a smooth surface. And the thickness of the plastic can also impact on the colour. To minimise this effect, it's essential to control the tool design & manufacture carefully - at Toolcraft, we've got the design know-how.
