Modern construction demands efficiency and precision, which is where innovative equipment transforms concrete block production. An Electric block machine uses automated features and energy-saving technology to streamline manufacturing whilst reducing manual labour and boosting productivity. These machines can produce thousands of blocks per shift, making them essential tools for construction projects of all sizes by offering reliable performance and cost-effective solutions for meeting tight deadlines.
What Is an Electric Block Machine?
An electric block machine uses an electric motor to automate concrete block production. These machines shape and compress concrete mixtures into blocks using powered vibration and pressure systems. Electric block machines deliver higher output rates than manual molds, producing 4,000–24,000 blocks per eight-hour shift based on model specifications.
Operators load materials like cement, sand, and aggregates into the batching unit. The machine mixes and pours the material into molds, where vibration and hydraulic compression ensure each block meets required density. After curing, blocks exit the machine ready for use in construction.
Lontto, with a sales and service office in Chicago, supplies electric block machines ranging from semi-automatic to fully automated models. Lontto machines include PLC control panels, robust steel frames, and wear-resistant molds to maintain precise sizes and shapes. Lontto offers onsite installation, training, and technical support for customers across North America.
