The digital factory: the key to unlocking the potential of a growing industry
Cathay produces polymers – an essential element for various chemical products – with bio-manufacturing, using renewable raw materials like corn instead of oil. Expanding the business meant reproducing a highly complex and sensitive laboratory process at an industrial scale. Cathay needed a technology partner who could provide the full potential of digital manufacturing. Consistency, repeatability, guaranteed quality and greater efficiency – this was the secret to Cathay’s successful expansion, and the key to a new future for the bio-manufacturing industry.
