There are many places where one can purchase plastic masterbatch. One can purchase plastic masterbatch at popular on the web sources such as PNC and Plastic Color.

I don't know all of the definitions but to the molded rubber industry it means:

A molded rubber part might require a few ounces of uncured rubber compound to be put into the mold to cure and make that part. It is unrealistic and expensive to put all of the ingredients together to make a few ounces of the right mix to make a part. So, there are two possibilities: a). we purchase several hundred/thousand pounds of the correct uncured mix from a vendor who specializes in making "masterbatch" and portion off a few ounces at a time to make parts; or, b). we buy a large quantity of "masterbatch" which contains most of the ingredients of most of our parts. When we have a specific order, we take a portion of the masterbatch and mix in various special ingredients to make the masterbatch perform in ways required by the part, once it is molded and cured. Then the part is molded and cured. To make it simple, masterbatch is the big pile of raw goop from which little piles of goop are extracted for a job to make parts for the customer.

In the actual production injection molding process, we generally carry out color differences from the following aspects.

Influencing factors and influencing factors

To select an injection molding machine with similar problems as showing the main product by BOM, if the machine appears, the equipment must be replaced.

The chromatic aberration caused by mold pouring, changing grooves, etc., can be solved by the maintenance mode of the corresponding part of the injection mold. The complexity of the problem and complexity of the problem can be addressed first to test the problem.

Eliminate the influence of raw resin and color masterbatch

Controlling raw materials is the key to completely solving chromatic aberration. Therefore, especially in the production of light-colored injection molded products, the obvious influence of the thermal stability of the raw material resin on the color fluctuation of the products cannot be ignored.

Given that most injection molding manufacturers do not produce plastic masterbatches or color masterbatches themselves, the focus can therefore be placed on production management and raw material inspection.

That is to strengthen the inspection of raw materials in storage; in production, the same product should be produced by the same manufacturer, the same brand of masterbatch, and color masterbatch as much as possible; for the color masterbatch, we should conduct a random inspection and color testing before mass production.

In this comparison, if the color difference is not big, it can be considered as qualified, just like the batch of color masterbatch has a slight color difference, the color masterbatch can be re-mixed before use to reduce the color difference caused by uneven mixing of the color masterbatch itself.

At the same time, we also need to focus on testing the thermal stability of the raw resin and color masterbatch. For those with poor thermal stability, we recommend that the manufacturer replace them.
