In-House Design & Control Software
Fully integrated design, control software, and data interfaces engineered for consistent performance and long-term reliability.
In-House Design & Control Software Engineering
Curtis Assemble & Test Ltd (CAT) manage every aspect of system design and software development in-house, ensuring consistent performance, seamless integration, and long-term reliability. By unifying mechanical, electrical, hydraulic, pneumatic, and control software design delivered in-house. CAT deliver efficient and fully integrated automation solutions tailored to complex production and testing environments.
Our multidisciplinary approach removes hand-offs, accelerates iteration, and ensures that design decisions align across all engineering disciplines from concept through to final commissioning. This reduces risk, protects quality, and enables faster project execution.
Integrated Mechanical, Electrical & Software Design
CAT’s integrated design process enables close collaboration between engineering teams, eliminating delays, reducing errors, and ensuring every detail of the system is aligned to customer requirements. With direct access to system designers throughout development, modifications can be implemented quickly without disrupting project schedules.
This approach supports coherent system architecture, accurate documentation, and compatibility across all major control hardware platforms, creating robust automation systems engineered for modern manufacturing and testing environments.
Control Software, HMI & Data Interfaces
CAT design and develop all machine control software and user interfaces in-house, guaranteeing compatibility with integrated equipment, sensors, and motion platforms. Software libraries, proven function blocks, and structured development processes shorten programming time, enhance reliability, and support future feature expansion without costly rework.
Systems include intelligent HMIs for operator interaction, status feedback, secure data acquisition, and traceability. This ensures operators can monitor key parameters, review measured performance, and maintain consistent product quality across production and validation environments.
