Since 1994
Before the upgrade, the company faced four constraints that capped its growth:
Inconsistent supply. Hollow blocks and bricks were sourced partly from traditional manual yards and partly from imports; quality, lead times and freight costs varied with each channel.
No controlled local capacity. Without its own line, the firm could not reliably meet the strength and dimensional specs that seismic-code-compliant housing and public works specify.
Language and service gaps. Imported equipment often shipped with English-only manuals and slow regional support — a real barrier for a Spanish-first crew.
Volume ceiling. Manual block-making capped daily output; the firm was turning away orders during peak building season.
The operator needed a semi-automatic line that could make multiple brick types on one machine, hold tight strength tolerances for seismic construction, run on a lean crew, and come with Spanish documentation and responsive regional support.
After a supplier review in 2020, the producer selected the QT4-15A — Dongyue's semi-automatic block machine built on table vibration plus hydraulic pressing . Note: the model is listed in our product range as "QT4-15A"; the written form "QT4A-15" used in the inquiry maps to this same semi-automatic variant. The QT4-15A produces hollow blocks, standard bricks and pavers on one line by changing molds, with a 24 kW installed power that suits a standard industrial supply. Dongyue handled pre-shipment FAT, on-site installation and commissioning in May 2020, operator training with Spanish manuals, and a spare-parts kit to keep the line running with minimal overseas dependency.
"Before the QT4-15A, we were buying from many small yards and importers, and our own output was never steady enough for the structural jobs our clients now demand. Now we make our own seismic-grade hollow blocks and standard bricks here in Ecuador on a machine with Spanish manuals and real local support. The blocks hold their strength and dimensions, our clients trust the quality for housing and public works, and the line paid for itself faster than we expected. We finally take the orders we used to turn away."
