Frequently Asked Questions

We manufacture a full range of concrete block making equipment, including:

• ✓ Semi-automatic machines (e.g. QT4-15) -- ideal for small startups, 4,800 pcs/8h
• ✓ Full-automatic machines (e.g. QT6-15) -- PLC-controlled, 7,200 pcs/8h, reduced labor cost
• ✓ High-capacity production lines (e.g. QT10-15) -- turnkey, 12,000+ pcs/8h
• ✓ Supporting equipment: mixers, batching machines, conveyors, auto pallet loaders, stackers, cement silos, color feeders

All machines can produce hollow blocks, solid blocks, paving blocks, curbstones, and interlocking bricks.

We understand this is a major concern for buyers. Our advertised capacities are based on standard 8-hour shifts using 400×200×200 mm hollow blocks with properly mixed materials. Actual output depends on block size, material quality, and operator skill. We provide real factory test videos and welcome virtual or on-site factory inspections before purchase. Our engineers will calculate realistic capacity figures for your specific block type and site conditions.

Our machines adopt European design principles with two key advantages:

• ✓ Airbag vibration system -- absorbs shock, extends machine lifespan, reduces noise by 30%+
• ✓ 4 vibration motors -- stronger, more uniform compaction for higher block density and better compressive strength

We also use Siemens PLC + Schneider electrical components on automatic models, ensuring reliability and easy local maintenance. Our 46,000 m² factory with 6 specialized workshops and 320+ engineers provides quality control that smaller factories cannot match.

Yes. All our machines are CE certified and manufactured under ISO 9001 quality management standards. We can provide full documentation including CE certificates, test reports, and material certificates for customs clearance and project compliance requirements.

We recommend the QT4-15 semi-automatic machine ($8,500-$14,000) as the best entry point. It is easy to operate with minimal training, has low power consumption (21 kW), and delivers a typical ROI within 6-10 months in most African, Asian, and Latin American markets. As your business grows, you can expand with additional units or upgrade to the QT6-15 automatic line.

Our pricing advantage comes from factory-direct supply -- no agents, no middlemen, no markup. We manufacture everything in our own 46,000 m² facility in Linyi, Shandong. European brands like Zenith or Poyatos charge 3-5× more primarily due to higher labor costs, dealer networks, and brand premiums. Our machines incorporate European design technology at Chinese manufacturing efficiency. Quality is not compromised -- it is validated by 108+ countries of export history.

• ✓ Lifelong technical support

We will clearly specify all inclusions in the contract before you commit.

Yes, we actively partner with established international traders and distributors. Exclusive agency arrangements are available for qualified partners who meet minimum annual volume commitments. Benefits include container-load pricing (up to −12%), priority production scheduling, co-branded marketing materials, and dedicated technical support. Please contact our sales team to discuss partnership terms.

We maintain in-stock inventory of our most popular models (QT4-15, QT6-15) for immediate shipment. Delivery timelines:

• ✓ In-stock machines: Ready to load within 3-7 business days of payment confirmation
• ✓ Custom or large orders: 20-45 days production + shipping time
• ✓ Ocean freight to Africa/MENA: 15-35 days from Qingdao Port
• ✓ Ocean freight to Latin America/SEA: 20-40 days

We provide real-time production progress updates and full shipping documentation (B/L, packing list, commercial invoice, certificate of origin).

Our factory is located in Linyi, Shandong, with convenient access to Qingdao Port -- one of China's largest export ports. We support multiple trade terms including EXW, FOB, CIF, and DAP depending on your preference. We can also assist with freight forwarding, customs clearance documentation, and insurance arrangements if needed.

We use professional export-grade packaging: heavy steel frames for the main machine body, wooden crates for components, and waterproof wrapping for all electrical parts. All items are secured inside standard 20ft or 40ft containers with anti-rust treatment applied. We have shipped 38+ containers per week with an excellent damage-free delivery record. Cargo insurance is recommended and can be arranged upon request.

Yes. We have extensive experience exporting to 108+ countries and understand local import requirements. We provide a complete documentation package including: commercial invoice, packing list, bill of lading, certificate of origin (CO), CE certificate, and any additional certificates required by your country (e.g. SONCAP for Nigeria, PVOC for Kenya). Our team will guide you through the process to minimize customs delays.

Absolutely. Customization is one of our core strengths. We can adapt machines for:

• ✓ Local raw materials: volcanic ash, laterite, crushed stone, fly ash, slag, etc.
• ✓ Custom block dimensions: any size from 100mm to 400mm width
• ✓ Local voltage and frequency: 220V/380V/440V, 50Hz/60Hz
• ✓ Site layout constraints: compact configurations for limited spaces
• ✓ Special block types: interlocking, permeable, colored face-mix blocks

Share your requirements with our engineers and we will design a solution specifically for your conditions.

Yes. Our turnkey solutions cover everything from raw material handling to finished block output, including:

• ✓ PLC batching + mixing system
• ✓ Block forming machine (main unit)
• ✓ Automatic pallet loader + conveyor system
• ✓ Auto stacker + cubing machine
• ✓ Cement silo (50T-200T)
• ✓ Color feeder for face-mix blocks

We also provide factory layout drawings, foundation plans, and electrical wiring diagrams as part of the package.

We warmly welcome factory visits. You can choose between:

• ✓ Virtual factory tour: Live video walkthrough of our 6 workshops, machine testing, and production line -- arrange within 48 hours
• ✓ On-site visit: We assist with travel arrangements to Linyi, Shandong. We can pick you up from Qingdao, Jinan, or Shanghai airports

Seeing is believing -- we encourage inspection before purchase and have nothing to hide.

We provide lifelong after-sales support backed by 320+ engineers and technicians. Our support includes:

• ✓ Remote troubleshooting via video call (24/7 for urgent issues)
• ✓ On-site installation and commissioning (30-day commissioning period for full lines)
• ✓ Operator and maintenance training on-site or via video
• ✓ Technical documentation in English and other languages
• ✓ Dispatch of engineers to your site for major issues

Spare parts availability is one of the most critical concerns for overseas buyers, and we take it seriously. We maintain a dedicated spare parts warehouse with common wear parts always in stock:

• ✓ Standard spare parts dispatched within 7 business days
• ✓ Emergency DHL/FedEx express shipping available (3-5 days worldwide)
• ✓ We supply a starter spare parts kit with every machine
• ✓ We recommend stocking a 6-month supply of wear parts (molds, vibration bearings, rubber pads) to avoid downtime

We provide a 12-month warranty on all machines from the date of commissioning or 18 months from the date of shipment (whichever comes first). The warranty covers manufacturing defects in structural components and electrical systems. Normal wear parts (molds, rubber buffers, vibration bearings) are consumables and not covered under warranty but are available at factory cost. Beyond the warranty period, we continue to provide technical support and spare parts for the lifetime of the machine.

Yes. Our European-design airbag vibration system with 4 vibration motors ensures superior block density and compressive strength. We have helped customers achieve blocks meeting ASTM, BS EN, and local African/Asian national standards. Our engineers will work with you to optimize mix ratios for your local materials to consistently achieve required strength grades (e.g. C3.5, C7, C10). We can provide sample test data from similar markets upon request.

We offer flexible payment terms to accommodate different buyer needs:

• ✓ T/T (Bank Transfer): 30% deposit, 70% before shipment -- most common
• ✓ L/C (Letter of Credit): Available for orders above $50,000
• ✓ Western Union / MoneyGram: For smaller accessory orders

For long-term partners and large project orders, we are open to discussing customized payment schedules. All terms are clearly stated in our contract.

This is a legitimate concern when buying from overseas. Here is how we build trust:

• ✓ We are a registered company with verifiable business license -- we will share all credentials upfront
• ✓ We have 108+ country export records and can provide customer references in your region
• ✓ Factory inspection (virtual or on-site) is available before any payment
