Automotive & Vehicle, Research & Manufacturing Automation
Partners in Producing the Cars of Today and Tomorrow
The days are long gone when Quality is left to chance, your process is only as good as the measurements you take and the evaluations you make. For the last 25+ years A-Tech has been partnering with industry leading manufacturers and OEM's, helping in producing better cars with greater efficiency.
It was not so long ago when visual inspection was done with calipers and a human eye and part handing was done by a human with gloves. The demands on the modern manufacturing environment is constantly evolving and that means accuracy, precision & speed are in heavy demand. A-Tech constantly scours the globe for the best technologies, then applies them as solutions to meet the ever growing challenges.
Quality control is paramount & cycle time is key. In most cases, no two applications are exactly the same, and a low cost solution that gives you versatile, near instant evaluation & serialized data collection is a fundamental requirement.
A-Tech has been involved in the wide range of activities that supports the Automotive and Specialty Vehicle industries. This includes Passenger Vehicles, Motorcycles, Electric Bicycles, Light and Heavy Duty Trucks, Buses, Construction Equipment, Timber Harvesting Equipment, Mining and Agricultural Machinery, Recreational Vehicles and Military Vehicles.
