Dongguan Anding Technology Manufacturing Co., Ltd. is a modern private enterprise integrating product development and design, Precision mold manufacturing, product injection molding, oil injection screen printing, and electronic assembly. It is located in Chuangye Road, Dongshan Village, Qishi Town, Dongguan City, with convenient transportation.

We mainly produce household appliances, digital, communication, office, computer, network and other precision plastics. Through case cooperation with different customers with different requirements, different models of Hot runner systems are used to process and manufacture molds. At the same time, various cutting-edge technologies such as ultra precision molds, IMD/IML are vigorously developed to increase the company's competitive advantage in technology. Home appliances are mainly PHILIPS, Toshiba, Hitachi, etc., remote control series are mainly Asus, Haier, Helian, Wanshiyi, etc., as well as office equipment product series.Plastic Mould  Start from part design analysis.

The matrix resin itself
The transparency of the matrix resin itself has a significant impact on the transparency of PP products. To improve the transparency of PP, a small amount of polyacrylate resin with good transparency and compatibility can be added.
2. Nucleating agent
It can significantly improve the crystallization rate, increase the crystallization rate and crystallinity ratio.
(1) Inorganic nucleating agents are mainly composed of ultrafine talc powder and SiO2, as well as calcium carbonate, mica powder, inorganic pigments and fillers. They are inexpensive and come from a variety of sources, but have a certain impact on the gloss and transparency of products.
(2) Organic nucleating agents are low relative molecular weight organic compounds with nucleation effects, represented by sorbitol and its derivatives. They have good compatibility with matrix resins and can significantly improve the transparency and surface gloss of products.
(3) In terms of the amount of nucleating agent, when the amount of nucleating agent exceeds 0.3%, the transparency improvement effect is not significant and may even decrease; But when the dosage is less than 0.2%, the nucleation quantity is insufficient and the transparency increase is insufficient. From this, it can be seen that the optimal amount of nucleating agent is between 0.2 and 0.3%. Therefore, an appropriate amount of nucleating agent can better improve the transparency of PP.
