Program 1-HDPE Products
1. All of our PE pipe production lines are purchased from Battenfeld-Cincinnati and KrassMaffei.
They are outfitted with online unit weight control and a wall thickness measurement system. The largest pipe diameter ranges up to 1200mm. PE fittings cover an extensive range of types and sizings, and electrofusion fittings with covered wire can adapt to various pipe diameters, making welding work easier. Our PE fittings cover more than 3,000 types, and the maximum size of the molded fittings is 450mm.
2. Cangzhou Mingzhu Plastic Pipe Research and Test Center obtained certification from the China National Accreditation Laboratory, as approved by CNAS.
Test devices in this center are imported from IPT Germany, Netzsch Germany, MTS, Setaram France, and Mitsubishi Japan, as well as other internationally known test device manufacturers. Among this product line, the RCP (rapid crack propagation) testing machine is the largest diameter testing equipment for PE pipes in the world, with a test diameter up to 400mm.
3. Cangzhou Mingzhu has passed ISO9001 quality management system certification, ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification.
All products have been tested and obtained related certificates from the National Test Center of Polymer and Chemical Building Materials, the State Bureau of Quality and Technical Supervision, the Ministry of Health of the People's Republic of China, Hebei Provincial Construction Department, Bureau of Environmental Protection and other relevant departments. Our PE pipes, PE fittings, ball valves, and steel/plastic transitions have obtained certificates of Manufacturing Licenses of Special Equipment in the People's Republic of China as issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China(AQSIQ). Cangzhou Mingzhu is the only company whose products have been entirely covered by this license. In January 2011, the non-metal welder test institute of Cangzhou Mingzhu Test Committee of Welder's Qualification obtained the approval the General Administration of Quality Supervision and the Inspection and Quarantine of the People's Republic of China. We also became a qualified supplier according to the standards set forth by the PE gas pipeline system quality control cooperation group G5+. We are now the largest professional PE pressure pipe and fittings manufacturer in China.
Program 2-BOPA Film/Polyamide Film
1. Our first foray into the production of BOPA film was in 2003. Using advanced technology (cast tenter frame simultaneous bi-axially orientated technology), our annual production capacity reached 5,000MTs.
2. In 2009, we acquired Shandong New DongLi, who was responsible for imported two cast tenter sequential bi-axially orientated PA film lines from Bruckner, however, the production lines did not run continuously. After 6 months, we made a technological breakthrough and have since been able to successfully run the line.
3. After years of technical reserves, we were able to design and assemble a new cast tenter frame simultaneous bi-axially orientated PA line, which was awarded independent intellectual property rights in the year 2010.
Program 3-Li-Ion Battery Separator
1. The Li-ion battery separator has been in development since 2008, and by 2009, Cangzhou Mingzhu successfully gained ownership of the dry uniaxially orientated technology with independent intellectual property rights.
The annual production capacity now reaches 100 million square meters of BOPA film, including 8 million square meters of thermostable separator. Our Li-ion battery separator is known for its higher safety performance, tensile strength, puncture strength and excellent thermostability. It has an excellent compatibility with an electrolyte solutions, allowing the batteries to have an outstanding electrochemical performance.
2. Cangzhou Mingzhu Separator Technology Co., Ltd. is a fully owned subsidiary of Cangzhou Mingzhu Plastic Co., Ltd.
As a specialized manufacturer of li-ion separators, we are certified to ISO9001, ISO1800 and ISO/TS16949 standards. As our products have become increasingly popular on the market, we have become one of China's leaders in the Li-ion separator industry.
3. Based on years of development, the multilayer lamination structure separator from Cangzhou Mingzhu is used in a wide range of fields, including EV power batteries, wind and solar energy storage batteries, communication station batteries, mobile or laptop digital batteries, and high discharge rate batteries for power tools and models.
According to customer requirements, we can adjust the production of our products and provide solutions to meet exact specifications.
