How To Solve The Problem Of Color Difference In Injection Products?
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.
What is master batch?
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.
Why is the luster of some injected products not good?
There are several possibilities as follows:1. The nozzle temperature of the injection molding machine is too low.2. The mold finish of the injection molding machine is not good.3. The molding cycle of the product is too long.4. The color masterbatch contains too much titanium dioxide.5. Bad dispersion of color masterbatch.6. After some time, some plastic products will fade.7. The quality of the basic pigment used in the production plant is not good, and the drifting phenomenon occurs.
Which masterbatch manufacturer to find?
Masterbatch-Manufacturer direct sales-Doleungchoi Specifications of masterbatches Masterbatch is a granular solid composed of particle size 0.1~3mm. 0.1mm (100μm) is a powder composed of particles; 1~10μm is a fine powder; 0.1~1μm is an ultra-fine powder; particles of 》3mm are broken solid blocks. The smaller the particle size, the more dense the mixture obtained. However, the smaller the particle size of the same solid, the easier the particles are also adsorbed to each other agglomerate, this agglomeration, in mixing with another solid particles is not easy to open, in the plastic melt is also difficult to disperse. Particle size distribution: masterbatch particle size distribution wide powder filling properties than the narrow particle size distribution more dense. Because the small particle size can enter the gap between the large particles to go, but the two kinds of particle size difference between the powder mixed, it is difficult to mix uniformly.
What is masterbatches?
Masterbatch (MB) is a solid or liquid additive for plastic used for coloring plastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process. The alternatives to using masterbatches are buying a fully compounded material (which may be more expensive and less open to e.g. color variability of the product), or compounding from raw materials on site (which is prone to issues with achieving full dispersion of the colorants and additives, and prone to preparing more material than what is used for the production run). In comparison with pure pigments, masterbatches require more storage space and their lead times are longer. Another disadvantage is additional exposure of heat ("heat history") to both the carrier and the additive; this may be important e.g. for marginally thermally stable pigments.[1] As masterbatches are already premixed compositions, their use alleviates the issues with the additive or colorant clumping or insufficient dispersion. The concentration of the additive in the masterbatch is much higher than in the end-use polymer, but the additive is already properly dispersed in the host resin. In a way their use is similar to uses of ferroalloys for adding alloying elements to steels. The use of masterbatches allows the factory to keep stock of fewer grades of the polymer, and to buy cheaper natural polymer in bulk. The masterbatches can be fairly highly concentrated (in comparison with the target composition), with high "let-down ratios"; e.g. one 25 kg bag can be used for a tonne of natural polymer. The relatively dilute nature of masterbatches (in comparison with the raw additives) allows higher accuracy in dosing small amounts of expensive components. The compact nature of the grains of solid masterbatches eliminates problems with dust, otherwise inherent for fine-grained solid additives. Solid masterbatches are also solvent-free, therefore they tend to have longer shelf life as the solvent won't evaporate over time. The masterbatch usually contains 40-65% of the additive, but the range can be as wide as 15-80% in extreme cases.[1] The carrier material of the masterbatch can be based on a wax (universal carrier) or on a specific polymer, identical or compatible with the natural polymer used (polymer-specific). E.g. EVA or LDPE can be used as carriers for polyolefins and nylon, polystyrene can be used for ABS, SAN, and sometimes polycarbonates. When a carrier different than the base plastic is used, the carrier material may modify the resulting plastic's properties; where this could be important, the carrier resin has to be specified. The usual ratio of masterbatch to the base resin is 1 to 5 percent. Several masterbatches (color and various additives) can be used together.[1] The carrier can also double as a plasticizer (common for liquid masterbatches) or a processing aid. The machines are usually fed with premixed granules of the host polymer and the masterbatch. The final mixing then gets done in the screw and extrusion part of the machine. This is sometimes prone to adverse effects, e.g. separation of the masterbatch and the base material in the machine's hopper. The masterbatch can be also added directly to the machine's screw, as a free-flowing solid or in case of a liquid masterbatch by e.g. a peristaltic pump. Such use of liquid masterbatches allows highly accurate dosing and quick change of color between machine runs.[2][3] Masterbatches can be used in most processes, except rotational molding and Plastisol and other liquid resin systems.

Why used masterbatch?
The use of color masterbatch has the following advantages: 1. Pigment performs better dispersion in the end-product : The masterbatch is an aggregate made by uniformly loading supernatant pigments in the resin. Colorants in the production process to be refined on the paint to improve the pigment dispersion and color strength. Special masterbatch carrier and plastic products of the same species, with good matching, after heating and melting pigment particles can be well dispersed in the plastic products. 2. Maintain the chemical stability of the pigment: Direct use of paint, because the storage and use of the pigment in the process of direct contact with the air, the pigment will occur water absorption, oxidation and other phenomena, and made color masterbatch, the resin carrier will be pigment and air, water isolation, can make the quality of the pigment long change. 3. To ensure the stability of the product color: Color Masterbatch particles and resin particles similar to the measurement more convenient and accurate, the mixture will not adhere to the container, and the resin mixture is more uniform, so you can ensure the stability of the amount of added, so as to ensure the stability of the product color. 4. Protect the health of the operator: Pigments are usually powdery, add and mix easily when flying, the body will be inhaled after the impact of the health of the operator. 5. Keep the environment clean, do not stain the vessel: 6. Simple process, easy color change, save time and raw materials: As the pigment in the storage and use of direct contact with the air, so there will be moisture absorption, oxidation, agglomeration and other phenomena, the direct use of plastic products in the surface of the color point, hue dark, easy to fade color, and caused by mixing Dust Feiyang, affecting the health of the operator. The masterbatch in the production process by mechanical processing, the pigment was refined, the pigment and resin carrier, dispersant fully mixed, so that the pigment and air, water isolation, thereby enhancing the pigment weather resistance.
Reduce the influence of injection molding process adjustment?
When the injection molding process parameters need to be adjusted for reasons other than a chromatic aberration, the injection production temperature, back pressure, injection cycle and the amount of color masterbatch added should not be changed as much as possible. At the same time, the influence of the process parameter change on the color should be observed.

What is a masterbatch and it's comparisons to a compound or compounding?
Masterbatch is the normal way of adding colourant to bulk, uncoloured resin. It comprises highly concentrated pigment, mixed with a carrier plastic, in a granule/pellet form. The granules/pellets are the same size and shape as natural (uncoloured) resins so are easy to handle (pigments are normally powder or liquid) and mix. Compounding is where the bulk plastic is all pre-coloured, usually by adding powder/liquid colourant during the extrusion/chopping process used to make the pellets. Compounding can be more convenient but is a little more expensive and limits flexibility for colour changes in production.
