Maintenance, Repair & Rebuild Services

HMI offers many support services for existing HMI and AMI-Presco equipment in the field. These services include our ability to maintain, document and rebuild older equipment using our extensive inventory and our order library. We maintain a history of sales and equipment builds, parts and drawing records that currently extends back more than 30 years. Within this wealth of information is every part, diagram, layout drawing and specification for every piece of HMI and AMI-Presco equipment made in that time frame.

HMI can provide preventive maintenance, routine troubleshooting and major unscheduled repairs with the full support of historical documentation specific to the individual machine being addressed. HMI technical service personnel are available for phone support and field service, while HMI customer service personnel are available for documentation and spare part support.

Our library of previous builds allows us to minimize design errors that may cause conflicts such as mechanical interference or improper revision when modifying or retrofitting your existing equipment with updates and enhancements. HMI can provide a full factory rebuild of your equipment back to its “factory new” condition, or we can modify and update the machine to current design specifications.

Using our in-house resources, HMI can provide you complete support for your HMI or AMI-Presco equipment in the field, both domestically and internationally.

Please specify the serial number of your equipment to expedite all inquiries.

Routine troubleshooting is available via phone or e-mail. Please be specific as to the nature of the problem.

Preventive maintenance is recommended, when budgets permit. A twice annual visit helps to prevent down time, improves equipment performance and minimizes the cost of the visit. PM visits can be combined to encompass multiple pieces of equipment, or to include additional tasks, such as training.


Proper documentation for your equipment helps to expedite repairs and can improve your understanding of the machine’s abilities, making your purchase both more dependable and more productive.

HMI can provide Operator Manuals, Mechanical Layouts and Electrical Schematics for your HMI or AMI-Presco equipment.

HMI offers a rebuild service. Whether you are seeking to rebuild your own equipment or to purchase used equipment that has been rebuilt and is now available for sale, HMI can provide you the opportunity to own a precision piece of HMI or AMI-Presco equipment at a percentage of the cost of a new buy.

Factory rebuilding your own equipment is an excellent way to restore the quality and efficiency of the original product and to minimize your investment in upgrading your production capabilities. During the rebuild, it is possible for HMI to update and modernize your equipment so that it carries the latest improvements in reliability and performance back to your assembly process.

Rebuilt used equipment will have all the same benefits of rebuilding your own equipment, with the added advantage of being available to increase production capabilities by adding capacity to the line. Previously owned equipment acquired by HMI to be rebuilt is only sold as available.

Spare Parts

HMI can provide spare parts for HMI and AMI-Presco equipment in the field. Our library of previous builds allows us to call up the parts list for your exact machine. This helps to ensure that your custom-built equipment gets the correct part.

Although our inventory is quite substantial, we don’t have everything on-hand. To prevent needless down time caused by extended waiting for spare parts, HMI offers many spare part kits specially design to meet the most frequently required spare parts for your piece of equipment. The most common spare parts are wear items such as bearings and switches. Having these parts on your shelf can get your equipment back up and running with minimal time off the line.
