Block Making Machine Quote: The Twelve Inputs That Set the Number

A block making machine quote is a function of the inputs you send, not of the supplier's mood. Two buyers can ask the same factory on the same day and receive numbers that sit in different bands entirely, because one sent a block size and a destination port, and the other sent a wish. The twelve inputs below are the whole difference. Fill them once, send them in one message, and every quotation that comes back is comparable line by line.

1. The twelve inputs, and why each one moves the number

A quotation is a calculation. Each input below changes a component size or changes what the machine must survive. An 80 mm aggregate loads the mixer differently from a 20 mm one. Leave one out and the supplier fills the gap with an assumption, usually a cheaper one than your site deserves.

• Product list and sizes. A 390 x 190 x 190 mm hollow block and a 200 x 100 x 60 mm paver need different moulds and different cycle times.
• Raw material and gradation. Maximum aggregate is 80 mm for pebble and 60 mm for crushed stone; above that the mixer and the feeding line change.
• Pallet size and material. An 850 x 560 x 20 mm steel pallet and a 1,400 x 1,400 x 30 mm pallet are different purchases and different wear items.
• Target shift output. Give a number per 8 hours in the block you actually sell, not a nameplate figure measured on another product.
• Power supply and stability. 380 V and 50 Hz, the transformer rating, and whether the line sits on the grid or on a generator.
• Automation level. Manual, semi-automatic, or fully automatic with pallet return and a palletising system. Installed power runs from 22.9 kW to 104 kW, with vibration force from 68 kN to 280 kN.
• Curing method. Natural, water spray or steam. It sets how many pallets stay in circulation and how much yard you must buy or rent.
• Site and area. The largest frame in the line measures 15,500 x 5,500 x 3,200 mm before the curing yard, the conveyor runs and the stock of blocks.
• Destination port and trade terms. FOB or CIF moves the number more than any machine option on the list.
• Voltage and frequency. A 380 V 50 Hz control panel will not run a 440 V 60 Hz plant without a change of components.
• Installation, commissioning and training. Who pays the engineer, the visa and the hotel, and how many working days are included.
• Spare parts. Moulds, wear plates, belts, sensors and filters. Ask what ships inside the container and what is ordered later.

2. What every complete quotation has to list

A number without a specification is not a quotation. Every line below should appear in writing, with a figure beside it. Main machine model, installed power from 22.9 kW up, and total weight in t. Mould sets supplied and pieces per cycle. Pallet count, pallet size and pallet material. Stacker or palletiser included or not, with its own power figure. Wear spares listed by name. Packing and reinforcement: sea-worthy crates, rust protection, container loading plan. What FOB includes and what CIF adds. Validity, normally 15 to 30 days, delivery time, and the days of installation, commissioning and operator training, including who pays the travel.

3. FOB and CIF: where the boundary falls

FOB ends at the port of loading. From the moment the container is lifted onto the ship, freight and marine insurance are yours. CIF carries the goods to your destination port, so the supplier buys the freight and the insurance and quotes one figure.

Onland costs and import duty are yours under both terms. Landed cost commonly runs 15% to 40% above the FOB figure once freight, duty and inland transport are counted, and the spread is wider on a 34 t line than on a 6,200 kg machine, because sea freight follows volume and weight. If your bank needs a CIF number, ask for FOB and CIF on the same page, from the same quotation, with one validity date.

4. Traps that hide inside a quotation

Four items go missing often enough to check on every quotation.

Moulds not included. A quotation for the machine alone leaves the mould as a separate purchase, and the mould decides which product you can sell at all. A short pallet count is the second trap: a line rated at 90,000 standard bricks per 8 hours needs pallets in circulation as well as pallets under the machine, and the curing yard sets that count.

No commissioning or training line means the first month is your problem. The fourth trap is a model name that promises a large line while the pallet size and the machine weight belong to a smaller frame. Cross-check the weight against the pallet: a 1,400 x 1,400 x 30 mm pallet belongs on a 34 t machine, not on a 6,200 kg one.

5. How to compare two quotations side by side

Put both quotations into one table, one row per line, and fill it cell by cell: model, installed power, machine weight, mould sets and pieces per cycle, pallet size and quantity, stacker included or not, spares list, packing, FOB, CIF, validity, delivery and training days.

Then compare like with like: same block type, same pallet, same shift output, same trade term. A cheaper quotation usually means fewer pallets, no stacker or a smaller mould set, so the missing lines appear as empty cells rather than as a lower price. Rebuild every offer on one output basis, at the 15 to 23 seconds cycle you were quoted, and check that the weight matches the pallet: a 1,400 x 1,400 x 30 mm pallet belongs on a 34 t frame that holds 31.5 MPa and 95 kN of vibration force, not on a 6,200 kg machine.

6. Input checklist you can copy to a supplier

Copy this list into a message, fill it in, then send it. These answers are what a quotation needs before it can be a number instead of a range.

• Products and sizes: every block, brick or paver you intend to sell, with length, width and height in mm.
• Raw material: cement, sand, fly ash, crushed stone or pebble, with the largest aggregate size available to you.
• Pallet: size and thickness in mm, steel or plastic, and how many you want to buy at the start.
• Output: pieces required per 8 hours, measured in the product that carries your volume.
• Power: voltage, frequency, transformer size, and whether a generator is present on site.
• Site: available floor area in square metres, curing method, and whether curing is indoors or outdoors.
• Automation: manual, semi-automatic or fully automatic, with or without a palletising system.
• Logistics: destination port, trade term FOB or CIF, and the delivery date you are working to.
• Scope: installation, commissioning, training days and spare parts, each on its own line.
