Overview

Hibar Systems Ltd was a Canadian industrial-automation company that designed and manufactured precision liquid-dispensing, metering, and filling equipment. The company originated in 1974, when German-born Canadian engineer Heinz Barall developed a metering pump capable of delivering extremely small and consistent quantities of liquid electrolyte into button-cell batteries. The prototype reportedly dispensed approximately two microlitres per cycle. After a major battery manufacturer evaluated the device and retained the prototype, Hibar began producing additional systems for battery manufacturing. The company's early specialization was the controlled handling of small quantities of liquids in processes where accuracy, repeatability, and production automation were important. Its systems were used in battery production, initially for button cells and later for other battery formats and applications. Hibar subsequently broadened its customer base and technical scope beyond batteries. Over roughly four decades, it developed equipment for filling printer-ink cartridges, dispensing pharmaceuticals into vials, packaging cosmetics, and performing other industrial liquid-filling operations. Battery manufacturing remained a central area of expertise. Hibar developed vacuum-filling systems for lithium-ion battery applications, a capability relevant to the production of cells used in consumer electronics, electric vehicles, and energy-storage systems. Its combination of precision pumps, automated handling, and application-specific filling machinery made the company attractive to manufacturers seeking to improve consistency and throughput in technically demanding production environments. Tesla became interested in Hibar's battery-related automation and acquired the company sometime in 2019. The transaction was not initially announced publicly by Tesla; it was subsequently identified through a Canadian government filing in October 2019. The acquisition occurred during a broader period in which Tesla purchased or brought under its control several smaller companies with expertise in manufacturing automation and battery technology. Following the acquisition, Hibar was integrated into Tesla's operations rather than continuing as an independent business. The Hibar signage was removed from the company's Richmond Hill office building in 2020, and the legal name displayed on its website was changed to Tesla Toronto Automation ULC in 2021. These changes indicate that Hibar ceased operating as a distinct standalone brand, although its engineering capabilities and personnel were incorporated into Tesla's manufacturing-automation activities.

History

Hibar Systems was established in Canada in 1974 by Heinz Barall, a German-born Canadian engineer. Its first important development was a precision metering pump designed to dispense very small quantities of electrolyte into button-cell batteries. The pump was reported to deliver approximately two microlitres with high consistency. A major battery manufacturer tested the prototype and was sufficiently impressed by its performance that it retained the device and ordered additional units. This early success established Hibar's position as a specialist supplier to battery manufacturers. The company built its business around the controlled movement and dispensing of liquids in automated production environments. Its equipment was intended for processes where a small error in volume could affect product performance, reliability, or yield. During the following decades, Hibar expanded from button-cell battery applications into a wider range of industrial markets. It supplied systems for filling printer-ink cartridges, pharmaceutical vials, and cosmetic packages, while continuing to develop machinery for battery production. Battery technology remained a major part of Hibar's technical development. As lithium-ion batteries became increasingly important, the company created vacuum-filling systems for lithium-ion battery applications. These systems were part of the manufacturing equipment used to introduce electrolyte into battery cells under controlled conditions. Hibar's experience with precision pumping, vacuum processing, and automated filling made it relevant to emerging battery-production requirements. By the late 2010s, Tesla was expanding its internal and acquired capabilities in battery technology and manufacturing automation. Tesla identified Hibar as a company whose equipment and expertise could support its battery and production ambitions. Tesla acquired Hibar sometime in 2019. The transaction was initially conducted without a prominent public announcement, but its existence became known through a Canadian government filing made public in October of that year. The purchase formed part of a wider acquisition period during which Tesla obtained several smaller businesses associated with automation or battery technology. After the acquisition, Hibar was not maintained as an independent operating brand. Tesla integrated the company into its own organization. The Hibar sign was removed from the Richmond Hill office building in 2020, and by 2021 the legal name on the Hibar website had been changed to Tesla Toronto Automation ULC. These developments marked the practical end of Hibar Systems as a standalone company, even though its technical capabilities became part of Tesla's broader manufacturing-automation activities.

Products and positioning

A specialist industrial-automation manufacturer focused on highly accurate, repeatable liquid dispensing and filling for battery, pharmaceutical, printing, cosmetics, and other manufacturing applications. Its strongest differentiation was precision at very small volumes combined with automated production integration.

Industrial pumping and dispensing · 1974
Precision metering pumps
Hibar's original technology was a precision metering pump capable of delivering very small, repeatable quantities of liquid. The initial application was dispensing electrolyte into button-cell batteries, where accurate dosing was essential to consistent cell performance. The pump concept formed the technological foundation for the company's later automated dispensing systems.
Battery manufacturing equipment
Automated battery electrolyte filling systems
These systems automated the controlled introduction of electrolyte into battery cells. Hibar supplied equipment to the battery industry from its early button-cell work onward and continued to develop filling solutions for newer battery-production requirements.
Lithium-ion battery manufacturing equipment
Vacuum filling systems for lithium-ion batteries
Hibar developed vacuum-filling equipment for lithium-ion battery applications. The systems used controlled filling processes to support the production of lithium-ion cells and represented the company's continued focus on battery manufacturing and precision automation.
