The main focus of production is on the serial production of wooden decimal scales. To make use of the resulting punching waste, the program is expanded to include Béranger table scales. Company CEO Walter Freudewald later recalls: "...instead of the open designs at that time, RHEWA table scales were delivered with an attractive sheet metal casing."

In 1912, they sell the company to the hardware wholesaler Paul Herzog. Under the name Herzog-Waagenfabrik, formerly Barmer Waagenfabrik C.A. Freudewald, it exists until 1962.

Until the entry of his younger son Walter into the company (1921), the senior boss once again manages the business alone. In 1914, Plant II is acquired. In the previously independent small-scale operation, running weight, coal, and livestock scales are manufactured.

In 1934, an expansion of the company takes place with the addition of a new warehouse and shipping building.

After the wounds of World War II began to heal, Karl-August Freudewald, the son of Walter Freudewald, joined the company in 1955 and started his career at RHEWA in purchasing. In 1957, he took over the leadership of the company.

In 1978, the first electronic RHEWA indicator was introduced.

The increasing share of electronic scales in the market was addressed in 1985 with the introduction of the first calibration-capable RHEWA indicator.

Leopold leaves the company in 2004 and pursues a career in forestry.

The original production of mechanical scales has been replaced by the development and production of state-of-the-art weighing electronics. Through consistent advancements, the use of high-tech in production, and years of experience, RHEWA ensures performance and quality. The company is market-oriented and focused on the future.
