How To Color The Pet Preform Mould

Posted by preform nicole on January 26th, 2019

Different color Pet Preform Mould are used every day, covering a wide range of applications and scenes, but few people know or consider how these colors are produced.

A wide variety of coloring systems can be used to color plastic materials, each with its own unique characteristics, advantages and disadvantages, with masterbatch, "salt and pepper" mixtures, liquid coloring and pre-colored plastics being the four most commonly used. Coloring method.

We are always looking to buy "natural" polymers such as nylon, LDPE, ABS and polypropylene pellets to color plastic injection molded products made from molds. After that, we mix the color concentrates purchased through the dosing unit so that the colorants are usually distributed anywhere from 1% to 4%. In order to color all of our natural polymers with an accurate amount of colorant, the dispensing unit needs to be calibrated and set up correctly.

The process of matching colors

In order to ensure that the different colors of the product are colored in the desired shade, we need to complete the color matching process in order to allow our team of experts to create specific color concentrations for specific applications. Typically, the chip, plaque or Pantone number (or ral number) can provide a general concept regarding the desired hue, while the particular formulation of the color concentrate can be identified by the information of the particular polymer selected.

In order to properly match the color of each polymer, we need to consider various factors, including viscosity and melt processing temperature. For example, a laboratory may require a formulation guide to determine the appropriate carrier resin, pigment system, stabilizer, and other additives for a particular product and application, as may be specified on the color matching application form. In addition, you need to remember that the gloss, appearance, and filler content affect the actual appearance of the color. For example, the colors of nylon and acrylic look different. In addition, in the color matching process, we need to consider factors such as environmental conditions, chemical resistance and FDA suitability.

Qualified colorant suppliers should be able to color match in any polymer system, including nylon, polypropylene, polyethylene, polyester, PVC, and acrylic. With the help of a computer color matching system, colors are measured, stored, and formulated using a color spectrophotometer. When preparing for color matching, the color matching system and lab-created chip files or nameplates will be used to store all of the different color and polymer systems.

In order to ensure the success of plastic coloring, we need to pay close attention to the details while adhering to the unique and specific requirements of the application. For example, the Jilian Pet Preform Manufacturers has a complete set of small window assembly molding processes that require colorants to provide resistance to fading and heat to ensure the desired function.
