Has any careful friend noticed the material of the household items we use in our lives? I found out that most of these household items are made of plastic, and few of them are made of all-iron and all-steel. But have any friends thought about how these plastic products are made? Is it to shape them like plasticine? So, where can we find such trustworthy injection mold manufacturers?

1. Choose the mold manufacturer according to the quality of the mold

To find this injection mold manufacturer with good quality and low price, we have to pay attention to what the quality of this manufacturer looks like.

      (1) The mold finish is poor, there are rust marks on the surface of the cavity, and the mold is poorly vented.

(2) The gating system of the mold is defective, the cold slug well should be enlarged, the runner, polished main runner, runner and gate should be enlarged.

(3) The material temperature and mold temperature are low, and local heating of the gate can be used if necessary.

(4) The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and dark surface.

(5) Plastics must be fully plasticized, but the degradation of the materials must be prevented, the heating must be stable, and the cooling must be adequate, especially for thick-walled ones.

(6) Prevent cold material from entering the part, use self-locking spring or lower nozzle temperature when necessary.

(7) Too much recycled materials are used, plastics or colorants are of poor quality, water vapor or other impurities are mixed, and lubricants used are of poor quality. (8) The clamping force should be sufficient.

2. Consider based on some factors

Then, if we want to find a trustworthy injection mold manufacturer, we must first examine whether it is a reliable mold design manufacturer, which is measured from the injection mold factory's technology, experience, business scale, and management philosophy. In addition, it is necessary to check whether the other party has a one-stop service manufacturer from mold design and manufacturing, product injection processing, plastic shell surface treatment (oil injection, silk screen, etc.), so as to avoid multiple suppliers from participating in the final product. In manufacturing, the risk is reduced to the greatest extent. After the comparison, the product after-sales service capability of the injection mold factory should be investigated, and all factors should be measured together, and finally an excellent supplier of the injection mold factory that meets the needs of the company is selected.

Based on our above understanding, we can find that there are reasons why so many people choose injection mold manufacturers with good quality and low price. In fact, these plastic products are solidified through a series of processing methods through customized special molds. This is also determined by the characteristics of the plastic itself. The plastic has a strong moldability and a very light weight. Whether it is used as a storage box or a tableware cup, it is light and resistant to fall.
