Company Profile
Regarded as one of the most versatile and indispensable materials across global industries, glass boasts boundless application potential through sophisticated processing technologies and professional additive formulas. As a professional and comprehensive glass manufacturer, Jinan Everest Glass Company Limited specializes in the R&D, production and global sales of diversified glass products covering borosilicate glass accessories, molded glassware, pharmaceutical packaging glass, lighting glass and daily-use glass products. As an important subsidiary of Shandong HonHai Industrial Group Company Limited, Jinan Everest Glass is designated to take charge of all international business sectors for the entire group.
Our glass tube and rod factory was officially put into operation in 1998. Since the foundation, we have focused on the production of 3.3 borosilicate clear and colored glass tubes, solid glass rods and a full range of hand-blown glass products. After decades of steady development, we have grown into a leading manufacturer in China's borosilicate glass industry, with an annual output of glass tubes exceeding 150, 000 metric tons and ultra-precise dimensional tolerance to meet industrial-grade standards. We provide professional redraw processing services for high-precision bore glass tubes and quartz tubes. These deep-processed products are widely applied in optoelectronic devices, optical fiber communication, medical equipment and other high-tech special fields. In addition, our product portfolio extends to laboratory scientific glassware, heat-resistant glass tea & coffee sets, baby glass bottles, lamp shells, glass water pipes and various customized hand-blown glass items.
Leveraging our self-developed electric furnace melting technology and rich manufacturing experience, we launched a specialized molded glass production base in 2001. This division focuses on high-strength tempered and heat-resistant borosilicate glass products. Our mainstream items include heat-resistant baking dishes, glass casseroles, airtight food storage jars and more daily-use molded glassware.
All our molded glass products support multi-scene use, which can be safely used in ovens, microwave ovens, refrigerators and dishwashers. Currently, the annual production capacity of our borosilicate molded glassware reaches 5, 000 metric tons, serving household goods distributors and supermarket chains globally.
We have maintained long-term dedication to the pharmaceutical glass packaging industry since the early stage of our development. This division is committed to producing medical-grade neutral borosilicate glass packaging materials that comply with international pharmaceutical standards.
Our product range covers USP Type I neutral borosilicate pharmaceutical glass tubes, tubular glass vials, ampoules, glass cartridges and prefillable syringes. With strict raw material screening and full-process quality inspection, our medical glass products meet the stringent requirements of global pharmaceutical enterprises, biotech laboratories and medical institutions. The annual turnover of the pharmaceutical glass division has reached approximately 30 million US dollars.
To cater to the booming global lighting industry, we established a dedicated lamp glass manufacturing plant in 1999. Equipped with professional melting and processing equipment, the factory can process multiple glass materials, including soda-lime glass tubes, leaded glass and lead-free glass tubes.
We supply diversified lighting accessories, such as lamp glass covers, shades, globes and chimneys. Our lamp glass products are compatible with indoor lamps, outdoor lanterns, decorative lighting and industrial lighting equipment, and we also support OEM & ODM customization according to clients' drawings and samples.
