Anqing Cify Grand New Material Co., Ltd. was established in 2010 (formerly known as Anqing City Everbright Resin Co., Ltd., established in 2004). The company is located in Anqing City, Anhui Province Daguan District Economic Development Zone, construction area of 20,000 square feet, is a professional research and development, production and sales of thermoplastic polyurethane (TPU) manufacturers. Products are divided into injection molding grade, extrusion level, ink level, hot- melt level, and other categories of dozens of products. After more than 10 years of development, the introduction of hardware and software facilities and world-class control of the Department, and the establishment of a series of standard quality management system, improve the process of production. In 2014, Anhui Science and Technology Department was identified as "hightechenterprises." "Customer first, integrity-based" is our company has always pursued the service concept, product sales to domestic and foreign. Company always concerned about customer needs - to do a good job pre -sale, sale and after-sales service.

tenQ: When products have air bubbles, how to solve this problem?
A:In the injection molding process, sometimes there are many air bubbles in the product, which will affect its strength and mechanical properties and product appearance is also greatly harmed. Usually products due to uneven thickness, or mold with protruding ribs, the material in the mold cooling rate is different, resulting in uneven contraction, easy to form bubbles, so the mold design to pay special attention.
In addition raw materials are not fully dried, still contain some water, melt in the heat decomposition into gas, easy to enter the cavity to form bubbles. Therefore, when the product bubbles, you can check the following factors, and do deal with.
The raw material is damp Thoroughly dried
Check the temperature,
injection pressure and injection time
Injection speed too fast Reduce injection speed
Raw material temperature is too high Lower melt temperature
Back pressure is low Increase back pressure to the appropriate
Finished section, rib or column too thick. Change finished product design or spout position
Sprue overflow is too small Increase the runner and entrance
Mold temperature is not equal Adjust the mold temperature to equal
Screw back too fast Reduce screw backing speed
Q: If your products Customizable?
A: Yes, we can recommend proper products to customers base on the requirements, or can improve the specification to meet their particular requires.
Q: How to solve the crystal point problem in thin-film TPU?
A: The high temperature and decomposition temperature of all additives should be considered,in the TPU processing temperature up to 200 ~ 220 under the conditions of decomposition will not be the formation of carbon impurities and the crystallization point.
Q: How to solve the warping of plastic product?
A: A:There's many reason for warping of plastic products , such as too fast to mold, mold temperature is too high, uneven molding temperature and flow system asymmetry.
2 of the greatest possibilities are:
Plastic parts thickness uneven or its corner is not smooth, and therefore can not cooling evenly, resulting in warpage.
Q: The Production of TPU Injection Black Point and Its Solution
A: 1. Workshop production environment is poor
2. TPU raw materials are not pure
3. Injection molding machine operation is not standardized
4. Machine operator's level of process debugging is not enough.
5. User's bad operating habits
6. Injection molding machines lack of cleaning and mainance
