User’s dilemma: Case
Supplying high-quality, high-viscosity glass paste in a short period
We produce glass paste that is widely used for sealing, coating, or insulation of various electronic components, and supply it to electronic device manufacturers.
As more and more devices are being widely used, there is a growing demand for a speedy supply of even higher quality samples.
Glass paste has quite high viscosity, so we have to mix it with a propeller mixer for five hours and then defoam with a vacuum defoaming machine for about 30 minutes. After that, we transfer the paste into customer-specified small-volume syringes before shipment. It is a time-consuming, complex task to transfer high-viscosity paste into small-diameter, long, and thin syringes.
It is also difficult to remove bubbles that are formed while the paste is being transferred into the syringe, so we need to take great care. Filling multiple syringes must be done quickly; otherwise, high-density glass particles will sediment, resulting in variations in material quality between syringes filled first and those filled last. Samples with variations cannot meet customers’ needs, so sometimes, we have to produce new paste again.
We recognize the need to review our manufacturing process in order to meet customers’ requirements—turnaround time reduction and high quality—at the same time.
