Since 1994
Before the upgrade, the company faced four constraints that capped its growth:
Inconsistent supply. Bricks and blocks were sourced partly from traditional fired-brick kilns and partly from small yards; quality, lead times and seasonal availability varied with each channel.
Low, manual output. Hand-mold and small-yard block-making capped daily output and tied up a large crew; the firm was turning away orders during peak building season.
Quality variance. Without controlled compaction and pressure, dimensional and strength tolerances drifted — a problem for housing and infrastructure specs.
Downtime risk. Over-complex equipment would have meant skills and spare-part gaps the local team could not absorb quickly.
The operator needed a semi-automatic line that was simple to run, low on downtime, strong on concrete-brick output, and backed by responsive regional support — without the capital and technical overhead of a fully automatic plant.
After a supplier review in 2019, the producer selected the QT4-15 — Dongyue's semi-automatic block machine built on table vibration combined with hydraulic top-pressure, with 360° rotary feeding and simple manual-valve control. The QT4-15 produces concrete bricks, hollow blocks and porous bricks on one machine by changing molds. Dongyue handled pre-shipment FAT, on-site installation and commissioning in May 2019, operator training, and a spare-parts kit to keep the line running with minimal overseas dependency.
"Before the QT4-15, we were buying from many small yards and fighting quality problems on every order. Now we make our own concrete bricks and hollow blocks right here in India, with steady density and sizes our clients trust — and the machine is so simple my local crew runs it without fuss. The line paid for itself faster than we budgeted, and we finally say yes to the housing and infrastructure contracts we used to turn away."
