Cambodia Customer Case: QT5-15 Interlocking Paver Production Line Proves Success, Leading to Second QT10-15 Purchase

Customer background

This project was invested by an Ukrainian businessman, who contacted Yixin back in 2008. He planned to launch a medium-scale concrete block manufacturing business in Sihanoukville, Cambodia, to supply local construction markets with versatile concrete building blocks. He was searching for a reliable mid-sized block machine that could produce both hollow blocks and decorative interlocking pavers, which were in steady demand for local residential, commercial and municipal paving projects. Many ordinary block machines he investigated lacked stable two-layer color feeding ability and suffered frequent material leakage from hoppers, which would ruin the appearance of colored pavers and raise waste costs. After online communication and a site visit to our running production plant, he decided to place an order for our QT5-15 block making line.

Needs and Challenges

During technical discussions with our Yixin sales and engineering team, the customer clarified his core project requirements:

Mainly produce interlocking colored pavers together with standard hollow blocks to diversify his product portfolio;

Equip with a dependable two-layer color feeding system, to make high-quality surface-colored pavers without color mixing or raw material leakage;

Medium production capacity, matching his medium investment scale and local market absorption in Sihanoukville;

Stable forming performance, consistent block dimension and good surface finish for paving projects;

Easy operation and convenient mould changeover to switch between hollow blocks and interlocking pavers quickly.

Meanwhile, the customer met several practical challenges:

Common paver machines on the market often have poorly sealed feeding hoppers, causing pigment leakage and uneven color on finished pavers;

Many block lines only support single-product production and cannot flexibly make both hollow blocks and colored interlocking pavers;

As a new investor in Cambodia, he needed mature equipment and trustworthy supplier support to reduce operational risks for his first block factory overseas.

After evaluating his product mix, target output and investment budget, our technical team recommended the Yixin QT5-15 automatic block forming machine equipped with our exclusive two-layer color feeding system. This configuration perfectly fits his business plan for interlocking pavers and hollow blocks.

Our specially optimized two-layer color feeder adopts anti-leakage sealing design for hoppers, effectively stopping color material leakage and segregation. Before shipment, we arranged trial runs in our factory, showing the customer stable colored paving effect. The anti-leakage feeding structure greatly impressed him and confirmed that QT5-15 was the ideal choice for his Cambodia factory. We completed full line installation and commissioning in August 2008.
