The plastic as well as the polymer industry has touched a new edge nowadays. Lots of industries from automotive to food, everyone is depending upon this industry in any respect. So, lots of research and innovations are operating on the polymers, and the plastic organics and new updates come in every minute. Here we will discuss some of the new directions of the plastic industry.
What color is your prototype?
Injection moulds are coming in different shape size and colors but they are same as small pellets. The color is totally depends upon the type of the resins used but all they fall somewhere on a monochromatic scale from clear through various shades of natural colors to black. So, we need to be very strict while doing the resin processing for the colors. To get more idea on this you must visit online plastics industry portal.
Color choosing process
Suppose a client requires red coloration; in that case you should add red stocked colorant to your base resins. In fact you can make new colors apart from the base color (red) like cherry red, flame red or transparent red easily if you become less careful and choosy while making the shades of the base resins. If you strictly go for the primary colors like blue and green then it becomes slightly difficult for everyone; for the manufacturer and the buyer.
How to get coloration as per your need
There are two ways to get colored injected molded parts. The first process is to mix the dye pellets into a batch of base resins. The pellets can able to give heat and compression to the injection into the mold & the base resin and dye pellets melt and mix together before being injected into the mold.
In the 2nd way, you need to order pre-compounded pellets to get your desired color. For example, a standard PMS color or match sample swatch is highly essential in this method.
Important things you need to remember
These are the list of some essential points you need to remember if you choose to have protomold with the colorant.
· The effect of base resin shade is greater on the lighter colors as compared to others. In a pre-compounded color, this can be adjusted in the compounding process, but becomes noticeable when you use Protomold stock colors.
· Protomold does not match to a specific color.
· Always check for the ‘swirling’ because dye pellets are mixed with base resin pellets in a salt pepper mix and cause swirling.
· Certain resins cannot play well with the colorants because of high temperature bearer the nylon and polycarbonate. These allow you to achieve color, but further limit your choice of hue.
