What This Machine Solves

Three production problems eliminated by this machine — with engineered, measurable solutions.

The Problem 1

Small fish-box and decorative-trim producers need block molding but cannot justify BM-1400 CAPEX at <1,000 blocks/month

How This Machine Solves It

BM-1200 (block size 1,200 × 600 × 300 mm, 6-8 min cycle, 20 kW) is sized for 300-800 blocks/month — entry-level CAPEX, fast payback.

The Problem 2

Entry-level block machines often skip steam-control PLC, leading to inconsistent block density and downstream cutting rejects

How This Machine Solves It

BM-1200 includes Siemens S7-1200 PLC standard — same as BM-1400 — keeps density variance under ±0.8 kg/m³ across blocks.

Working Principle

BM-1200 fuses pre-expanded EPS beads into 1,200×600×300 mm blocks via steam injection from top + bottom mold halves. PLC controls steam pressure, heating time, vacuum cooling, and ejection.

Step 1

1. Bead Loading

Aged EPS beads pneumatically conveyed from aging silo to mold via injector — fill time 25-40 s.

Step 2

2. Steam Injection

0.08-0.12 MPa steam injected into mold chamber for 60-90 s from top + bottom halves (supplied from a 0.4-0.8 MPa steam tank via pressure-reducing valve) — beads soften and fuse together.

Step 3

3. Vacuum Cooling

Vacuum pump pulls down 80-90 kPa for 90-150 s — accelerates internal cooling, prevents block deformation on ejection.

Step 4

4. Block Ejection

Mold opens; pneumatic ejector pushes the finished block onto roller conveyor for aging or direct cutting.

Engineered Performance Advantages

Every advantage backed by measurable specs — no marketing claims without data.

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.

Cycle Time

6-8 min

vs BM-1400 typical 5-7 min

Slightly longer cycle due to smaller heat-transfer area — acceptable trade-off for small-block applications.

Steam Consumption

30-40 kg/cycle

vs BM-1400 typical 40-55 kg/cycle

Smaller block = less steam — lower steam-generator and water consumption costs.

Block Size

1,200 × 600 × 300 mm

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

Sweet spot for downstream CM-2000 cutting machine — minimal off-cuts.

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.
