QT4‑15 Automatic Concrete Brick Making Machine Overseas Production Case

1. Project Overview

Equipment Model: QT4‑15 Fully‑automatic Concrete Block Forming Machine

Project Location: Commercial brick plant in Southeast Asia

Production Products: Concrete hollow blocks, standard solid bricks, paving bricks, interlocking bricks, perforated blocks, curb stones

Process Raw Materials: Sand‑stone aggregate, crushed stone, ordinary Portland cement, fly ash, slag, stone powder, construction waste recycled aggregate, mineral color pigment

Equipment Configuration: QT4‑15B forming main unit, hydraulic power station, PLC automatic electric control system, automatic pallet feeding mechanism, brick output conveyor, compatible with batching mixing station, feeding hopper system, cement silo

2. Project Site Introduction

This is a commercial building‑material brick factory in Southeast Asia with semi‑open workshop. After installation and commissioning, QT4‑15B runs continuous mass production. Mixed raw materials are conveyed into machine hopper. By hydraulic‑high‑frequency vibration composite molding, hollow blocks and solid bricks with neat edges and precise dimensions are discharged onto pallets.

Fresh bricks on pallets are stacked for natural curing. Finished blocks supply local residential construction and urban infrastructure projects. Different brick types can be produced by quick mold replacement. Pallet feeding, material distributing, pressing and brick‑discharging work in automatic cycle. Only a small number of workers are required for material supply, pallet transfer and finished‑product stacking. Local sand, stone powder and industrial residues are fully utilized to cut raw‑material cost. Finished products are directly supplied to local construction market.

3. Core Equipment Advantages

① Hydraulic‑vibration composite molding

Hydraulic pressure cooperates with high‑frequency vibration for even material distribution. High compaction brings stable brick strength and accurate dimension. Hollow holes are well‑formed with low reject rate, meeting local construction quality standards.

② High automation & stable productivity

Automatic cycle delivers steady output for medium‑small brick‑plant mass production. Quick mold change supports hollow blocks, solid bricks, paving bricks and curb stones. Multi‑product capacity expands customer business scope.

③ Wide raw‑material adaptability

Local sand and stone powder work as basic materials. Fly ash, slag and recycled construction waste can be mixed in formula. Color pigments produce colored paving bricks. Local industrial residues are reused to reduce production expenditure.

④ PLC intelligent control system

Full‑auto cycle for pallet feeding, distributing, pressing and brick discharging. Touch‑screen adjustable parameters bring user‑friendly operation. Local workers can operate skillfully after short‑term training and labor threshold is lowered.

⑤ Rigid frame for overseas working conditions

Thickened welded frame resists vibration for long‑time continuous operation. Stable hydraulic system and easily‑replaceable wearing parts simplify maintenance, which fits overseas factory operation conditions.

4. Customer Evaluation

The customer is satisfied with stable performance of QT4‑15B. High‑automation reduces labor cost. Qualified hollow blocks and solid bricks meet large demand of local civil construction. Quick mold change handles diversified orders flexibly.

The machine works well with local sand and stone powder to keep raw‑material cost under control. Low failure rate and easy maintenance allow on‑site staff to finish daily service independently. The customer regards QT4‑15B as a cost‑effective automatic brick‑making solution for medium‑small commercial brick plants in Southeast Asia.
