Challenge

Before the upgrade, the company faced four constraints that capped its growth:

• Inconsistent supply. Hollow blocks, bricks and paving stones were sourced partly from traditional small 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 dimensional and color tolerances demanded by larger housing, industrial-park and municipal projects.

• No in-house decorative product. Colored paving stones had to be resold from third parties — a thin-margin line the firm could never manufacture to its own spec.

• Volume ceiling. Manual and small-yard block-making capped daily output; the firm was turning away orders during peak building season.

The operator needed an automatic line that could make multiple brick types on one machine, add in-house colored pavers via face-mix, run on a lean crew, and come with responsive regional support for a fast-growing Southeast Asian market.

Solution

After a supplier review in 2015, the producer selected the QT10-15 — Dongyue's high-output automatic block machine built on table-mold synchronous vibration with PLC and HMI control, and equipped with a face-mix (color layer) device for colored paving bricks. The QT10-15 produces hollow blocks, porous bricks, standard bricks and colored paving stones on one line by changing molds. Dongyue handled pre-shipment FAT, on-site installation and commissioning in January 2015, operator training, and a spare-parts kit to keep the line running with minimal overseas dependency.

Why it fit — and why high-output automation mattered

• Localized, scaled supply. In-house hollow blocks, standard bricks and colored pavers replaced mixed imported and small-yard sourcing; lead times and quality variance fell sharply.

• One machine, multiple products — including decorative. The face-mix device lets the client produce its own colored paving bricks, moving from thin-margin reseller to on-spec manufacturer.

• Controlled quality at volume. Table-mold synchronous vibration and PLC + HMI control hold tight dimensional and color tolerances that larger housing and municipal projects specify.

• Lean crew. Full automation runs the line on a smaller team, reducing labor intensity versus manual block-making.

Results

• Import and small-yard substitution. Local hollow-block, standard-brick and paving output removed reliance on mixed imported and small-yard supply, with its freight, lead-time and quality variance.
• In-house decorative margin. The face-mix device turned colored pavers from a thin-margin resale line into an on-spec, higher-margin manufactured product.
• Hollow block / 8h shift +257%
• Standard brick / 8h shift +161%
• Labor / shift −44%
