Background
A factory in the US that manufactures flip top bottles made a call to Minghang for help in developing customized glass bottles for its product line which is rapidly growing. The flip top bottle factory wanted to present new designs featuring uniquely shaped products, secure flip-top closures, and strong glass quality but was unable to find a partner who could meet these specifications and at the same time maintain production efficiency.
Challenges
The main problems of the factory were how to make dependable molds for various bottle styles, produce the same quality glass every time, and also install the flip top closures that fit perfectly. The suppliers that the factory had didn’t have the technical ability and flexibility to solve the problems of the different design requests which resulted in a high rate of defects and the delivery time was not consistent.

Solutions
Tailored Bottle Design and Engineering
Minghang engineers worked hand in hand with the factory that produces flip top bottles to design new types of molds which were not only functional but also looked great. The designers changed the designs to assure that the product is airtight and that the hinge works smoothly. These features are very important in flip-top high-quality bottles.
Production Optimization and Quality Assurance
With very accurate temperature control and automated molding machines the entire production process was made more efficient. In addition, strict quality controls at every stage ensured that the products had the same level of clarity, strength, and sealing reliability from batch to batch.
Material and Supply Chain Support
Minghang helped by providing good quality raw glass and also by managing the transport of the materials so that the factory would not have to deal with long waits. Through this assistance, the factory was able to lower its waste, increase its output, and always meet the deadlines of its customers.
