Deliver, Shipping And Serving
Before the sale, we confirm the demand for the product with the customer, and quote the customer according to the product drawings or product samples provided by the customer. After waiting for the customer to confirm the quotation, the company will open the mold order through the customer. The production of the test mode will be carried out, and the test mode can be completed in 20-30 days from the receipt of the order. After the customer confirms that the sample is OK, we will carry out mass production according to the order quantity, and the general delivery time is 3-7 days. After the sale, we will deal with the products with abnormal quality. If the products produced have quality problems, we will reply to the improvement report if the customer complains. If the products cannot be used, our company will arrange replenishment and finally meet the requirements of the customers.

Common defects of plastic masterbatch
1. In the sun exposure, the products have stripes of paint belt
This problem should be considered from two aspects of plastic physical and mechanical properties and plastic molding process:
1.1 The temperature of the injection molding equipment is not well controlled, and the color master cannot be fully mixed with the resin after entering the mixing chamber.
1.2 The injection molding machine does not add a certain back pressure, screw mixing effect is not good.
1.3 Poor dispersion of color masterbatch or poor plasticization of resin.
The process can be adjusted as follows: 1. The mixing chamber against the blanking part of the temperature slightly increased If it is still not good after the above debugging, it may be the dispersion of the masterbatch, resin or matching problem, should contact the manufacturer of the masterbatch to solve.
2. The use of a certain color mother, the product appears more easily broken
This may be due to the manufacturer's choice of dispersant or additive quality caused by poor diffusion miscibility, affecting the physical and mechanical properties of products.
3. The color is too dark (too light) after use according to the proportion of the color master instruction.
Although this problem is simple, there are many possibilities, specifically as follows:
3.1 The color master has not been carefully tested, too little or too much pigment
3.2. Measurement is not accurate when used, and there is a large number of random measurement by domestic enterprises, especially small and medium-sized enterprises
3.3. There are problems in the matching between masterbatch and resin, which may be due to improper selection of carrier of masterbatch, or the manufacturer may change resin varieties at will
3.4. The temperature of the machine is not proper, and the color master stays in the machine for too long Processing procedures: first check whether the resin variety and color master match, measurement is accurate, then adjust the machine temperature or speed, if there are still problems should contact the color master manufacturer.
4. The same master color, resin and formula, different injection molding machine injection out of the product why the color?
This is often the cause of injection molding machine. Different injection molding machine due to the different manufacturing, use time or maintenance status, resulting in the difference in mechanical state, especially the heating of the original and the difference in the degree of adhesion to the cylinder, so that the color master in the cylinder dispersion state is not the same, the above phenomenon will appear.
5. For another brand of resin, the same master color and formula, color has changed, this is why?
Different type of resin its density and melt index will have difference, so the performance of the resin will have difference, and the compatibility of color master also can have differences, so as to change color, generally speaking, as long as its density and melt index were similar, so the color difference is not too big, can be more is by adjusting the dosage of the masterbatch color.
6. Will the transfer of pigment during the storage process affect the quality of the product?
Some masterbatch pigments have a high pigment content (or dye), in which case migration is normal. In particular, the addition of dye masterbatch, will occur serious migration phenomenon. However, this does not affect the quality of the product, because the color mother injection into the product, the pigment in the product at the normal color concentration.
7. Why some injection products are not shiny?
There are several possibilities:
7.1. Nozzle temperature of injection molding machine is too low
7.2. Mold finish of injection molding machine is not good
7.3. product molding cycle is too long
7.4. Too much titanium dioxide in the color masterbatch
7.5. The dispersion of color masterbatch is not good
8. After a period of time, some plastic products will occur fading phenomenon.
The basic pigment used by the manufacturer is of poor quality and drift occurs.
9. Why ABS master color is particularly prone to color differences?
Different brands of ABS produced in different countries have larger color difference, even if the same brand of ABS, each batch number may have color difference, color difference will certainly occur after the use of color masterbatch coloring. This is caused by the characteristics of ABS, there is no complete solution in the world. But, this kind of chromatic aberration is not serious commonly.
