Inside the Machine — Core Components

Eight engineered subsystems that make this machine production-grade. Each component is sourced, built, and tested for industrial duty cycles.

1. Horizontal Block Mold (Multi-Bay Layout)

Function

High-strength horizontal mold chamber with multi-bay layout — produces blocks 1,200-1,800 mm long × 600-1,200 mm wide × 300-600 mm high depending on machine model (BM-1200 to BM-1800).

Engineering Details

Boiler-grade industrial steel main body (welded, pressure-vessel grade). Inner walls: 0.3mm 304 stainless steel wedge plates with engineered hole pattern (12% open-area ratio). External body: mineral-wool insulation + galvanized exterior plates. Single front-door opening minimizes steam + vacuum leakage. TUV / Bureau Veritas pressure-vessel certified.

2. Steam Tank (0.4-0.8 MPa Working, Pressure-Vessel Certified)

Function

Stores and supplies steam to mold chamber — buffer between boiler and machine for stable steaming cycles. Sized 0.5-1.0 m³ depending on machine model.

Engineering Details

AISI 304 stainless steel pressure vessel + Type 20G boiler-grade frame. Working steam pressure 0.4-0.8 MPa with safety relief valve at 2 bar max. Gemu-Germany or Burkert-Germany pressure-reducing valve + steam regulating valve. Insulated to minimize heat loss. TUV / Bureau Veritas certified.

3. Air Receiver Tank (Pneumatic Power for Fill + Eject)

Function

Compressed-air storage powering pneumatic actuators, fill injectors, and ejection cylinders throughout each molding cycle.

Engineering Details

Vertical pressure vessel with safety relief valve + drain + pressure gauge. Working air pressure 0.5-0.7 MPa / consumption 1.0-1.2 m³ per cycle. Capacity 0.3-1.0 m³ depending on machine size. Festo-Germany pneumatic control unit + multi-injector hydraulic fill array. Water consumption 0.4-0.5 m³/day.

4. Twin-Motor Vacuum Pump (Water-Ring, Parallel Configuration)

Function

Twin-motor parallel vacuum pump for fast cooling and ensuring block compacting — twin redundancy enables continuous operation even if one motor needs maintenance.

Engineering Details

2 × water-ring vacuum pumps in parallel (7.5-15 kW each depending on machine size, Becker / Edwards-class performance). Cylindrical vacuum buffer tank 5-7 m³ with water spraying + sieving units. Reaches 0.06 MPa absolute in 30-60 seconds. Water-spray cooling reduces residual moisture <0.5%.

5. Control Cabinet (Siemens S7-1200 PLC + 99-Recipe HMI)

Function

PLC control system supervising the full cycle (fill → steam → vacuum cool → eject) with recipe-based control for quick changeover between block sizes and densities.

Engineering Details

Siemens S7-1200 PLC + 10-12" Weintek HMI touch screen . 99-recipe storage library for SKU changeover. USB recipe export + optional Ethernet/IP for MES integration. Triple safety: computer supervision + real-time pressure feedback + hardware safety relief valve. Multi-user audit trail. Power: 380V / 50Hz / 3-phase.

O Que Esta Máquina Resolve

Três problemas de produção eliminados por esta máquina — com soluções engenheiradas e mensuráveis.

O Problema 1

Pequenos produtores de caixas de peixe e molduras decorativas precisam de moldagem de bloco mas não justificam CAPEX de BM-1400 a <1.000 blocos/mês

Como Esta Máquina Resolve

BM-1200 (tamanho de bloco 1.200 × 600 × 300 mm, ciclo 6-8 min, 20 kW) é dimensionada para 300-800 blocos/mês — CAPEX de nível básico, payback rápido.

O Problema 2

Máquinas de bloco de nível básico frequentemente omitem o PLC de controle de vapor, levando a densidade de bloco inconsistente e refugos de corte posteriores

Como Esta Máquina Resolve

BM-1200 inclui PLC Siemens S7-1200 de série — igual à BM-1400 — mantém variação de densidade abaixo de ±0,8 kg/m³ entre blocos.

Princípio de Funcionamento

BM-1200 funde pérolas EPS pré-expandidas em blocos de 1.200×600×300 mm via injeção de vapor pelas metades superior + inferior do molde. PLC controla pressão de vapor, tempo de aquecimento, resfriamento a vácuo e ejeção.

Step 1

1. Carga de Pérolas

Pérolas EPS maturadas são transportadas pneumaticamente do silo de maturação ao molde — tempo de enchimento 25-40 s.

Step 2

2. Injeção de Vapor

Vapor a 0,08-0,12 MPa injetado na câmara do molde por 60-90 s pelas metades superior + inferior (fornecido de tanque a 0,4-0,8 MPa via válvula redutora) — pérolas amolecem e se fundem.

Step 3

3. Resfriamento a Vácuo

A bomba de vácuo reduz para 80-90 kPa por 90-150 s — acelera resfriamento interno, previne deformação do bloco na ejeção.

Step 4

4. Ejeção do Bloco

O molde abre; o ejetor pneumático empurra o bloco acabado para o transportador de rolos para maturação ou corte direto.

Vantagens de Desempenho Engenheiradas

Cada vantagem respaldada por especificações mensuráveis — sem alegações de marketing sem dados.

Twin-Motor Vacuum (Parallel Redundancy)

2 × 7.5-15 kW pumps

vs Single-pump competitors: full stop if pump fails

Two water-ring vacuum pumps in parallel configuration. If one motor needs maintenance, the other continues — no production stop. Critical for 24/7 fish-box / cooler production lines where unplanned downtime = lost orders.

Horizontal Layout (Floor Flexibility)

Single-level access

vs Vertical molders: 5-7m tall, gantry required

Horizontal layout means single-level operator access — no mezzanine, no gantry crane, no overhead clearance needed. Easier maintenance, lower install cost, fits any standard industrial ceiling (4m).

Block Size Flexibility

1.2-1.8 m × 0.6-1.2 m × 0.3-0.6 m

vs Vertical: fixed tall blocks (6m only)

4 block sizes (BM-1200/1400/1600/1800) cover small fish-box molds to large insulation blocks. Pick mold size per downstream cutting line — single machine adapts to multiple SKUs without modification.

Single-Door Opening

< 5% steam/vacuum leakage

vs Multi-door competitors: 15-20% leakage

Single front-door design minimizes steam + vacuum leakage. Better pressure containment = more consistent block density ±3% across full 8-30 kg/m³ range.

Triple Safety System

TUV / Bureau Veritas certified

vs Industry typical: 1-2 safety layers

Computer supervision + real-time pressure feedback + hardware safety relief valve. Pressure-vessel certified for EU / North America / Latin America / Southeast Asia export.

Tempo de Ciclo

6-8 min

vs BM-1400 typical 5-7 min

Ciclo ligeiramente mais longo devido à menor área de transferência de calor — compromisso aceitável para aplicações de bloco pequeno.

Consumo de Vapor

30-40 kg/cycle

vs BM-1400 typical 40-55 kg/cycle

Bloco menor = menos vapor — custos menores de gerador de vapor e consumo de água.

Tamanho do Bloco

1,200 × 600 × 300 mm

vs optimised for fish-box / cooler-box / decorative-trim cutting

Ponto ideal para máquina de corte CM-2000 a jusante — refugos mínimos.

Product FAQ

The questions buyers ask most often before placing an order.

When should I choose BM-1200 over BM-1400?

BM-1200 is the right choice if you produce thinner blocks (300mm height) or smaller block sizes for specialty packaging. Below 500 blocks/month, BM-1200's lower CAPEX (Contact us for pricing vs BM-1400's 80-110k) pays back faster. Above 500 blocks/month, BM-1400 wins on throughput per machine.

What block sizes can BM-1200 produce?

Standard 1,200 × 600 × 300 mm. The quick-change cavity insert allows variations: 1,200 × 600 × 200mm thin blocks for ceiling panels, 1,200 × 600 × 400mm thicker blocks. Mold-change 4-6 hours.

What density range and bead grades does BM-1200 handle?

8-30 kg/m³ (±3% tolerance). Compatible with standard EPS and fast-cycling beads. For FR/graphite EPS at the upper end of that range, consider BM-1400 or BM-1800 for higher throughput.

Steam boiler requirement?

Minimum 0.5 ton/h at 0.2 MPa. Most small factories use 0.8 ton/h boiler.

Ships to 220V/60Hz?

Yes — factory build option. No price difference; 2-week lead time adjustment.

Cycle time and daily throughput?

Cycle 4-6 min depending on density. 8-10 blocks/hour single-shift = 60-80 blocks/day. Two-shift operation reaches 120 blocks/day.

Are you a manufacturer or a trading company?

We manufacture. Block molding machines are built in our own plant, and the BM-1200 / BM-1400 / BM-1600 / BM-1800 variants on this page are our own model series, not resold equipment. You are welcome to visit before ordering, and to ask for the machine to be run in front of you at the factory. The two videos further up this page are footage from customer lines, not renders.

Which block molding machine model should I ask you to quote?

Give us three numbers and we will quote against them rather than send a catalogue: the largest block dimension you need, your target density in kg/m³, and blocks per day. Those three eliminate most of the four variants immediately. If you do not have them yet, the specification table above is ordered smallest to largest.
