What This Machine Solves

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

The Problem

Standard SPQ-B chokes on dense graphite-EPS particles — wire sag, dust buildup, premature wire breakage cuts effective uptime to 60-70%

How This Machine Solves It

SPQ-FR uses 0.5-0.8mm thicker nichrome wires + 34 kW heating (vs 26 kW on SPQ-B) — sustains 95%+ uptime on graphite blocks up to 45 kg/m³.

The Problem

Graphite-EPS dust is combustible per ATEX zone-22 — using standard cutters creates fire risk + insurance/certification problems

How This Machine Solves It

Built-in ATEX zone-22 dust extraction with HEPA filtration + anti-static pneumatic conveying eliminates the dust ignition risk that plagues retrofitted standard cutters.

The Problem

Higher-density FR-grade EPS weighs 50-80% more than standard EPS — standard conveyor rollers wear out in 6-12 months

How This Machine Solves It

Reinforced HRC 55+ surface-hardened rollers + heavier 11 kW motor sustain 36-month service life on FR-grade material.

Working Principle

Same 6-stage continuous cutting cycle as SPQ-B but engineered for graphite/FR-EPS: heavier wires, higher heating, ATEX dust capture, slower travel speed (0.5-1.2 m/min vs 0.6-2 on SPQ-B).

Step 1

1. FR Block Storage

Aged graphite/FR-EPS blocks staged on carousel — anti-static handling to prevent ignition risk.

Step 2

2. Tilt & Align

Hydraulic tilter with grounded surface; pneumatic side-clamps square block to frame zero.

Step 3

3. Horizontal Cut

60 thicker (0.5-0.8mm) nichrome wires slice block at slower 0.5-1.2 m/min; dust extraction simultaneously active.

Step 4

4. Vertical & Cross Cut

Same as SPQ-B but each wire bank has independent dust capture hood.

Step 5

5. ATEX Dust Capture

Pneumatic conveyor (Ø150mm, anti-static, ATEX zone-22) routes all dust + scrap to HEPA filtration unit.

Step 6

6. De-stacking

Sheets discharged onto grounded conveyor; FR-additive QC sample taken every batch.

Engineered Performance Advantages

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

Wire Heating Power

34 kW

vs SPQ-B: 26 kW

30% more heating capacity handles dense FR/graphite wire friction without sag.

Wire Diameter

0.5-0.8 mm

vs SPQ-B: 0.35-0.6 mm

Thicker wires resist breakage on graphite particles. Service life 36-48 months vs 12-18 on retrofitted standard cutters.

ATEX Zone-22 Certified

Built-in

vs standard cutters not certified

Mandatory for graphite-EPS production. Retrofitting standard cutter for ATEX costs USD 15,000+ extra.

Density Range

15-45 kg/m³

vs SPQ-B: 12-35 kg/m³

Top end extended to handle premium FR-grade EPS for high-rise insulation.

Insurance Compliance

EN 60079-31 + EN 1127-1

vs standard cutters fail audit

Insurance underwriters require ATEX certification for graphite-EPS production lines.

Product FAQ

The questions buyers ask most often before placing an order.

Why can't I just use standard SPQ-B for graphite-EPS?

Three reasons. (1) ATEX compliance — graphite dust is combustible per zone-22 classification, standard cutters fail insurance audit. (2) Wire wear — graphite particles abrade standard 0.35mm wires causing breakage every 3-5 hours; SPQ-FR's 0.5-0.8mm wires last 200+ hours. (3) Dust load — standard cutters lack HEPA extraction, dust accumulates in cabinet causing fire risk.

Can SPQ-FR also cut standard (white) EPS?

Yes — backward compatible with standard EPS (12-35 kg/m³). The thicker wires and higher heating just consume slightly more power on standard EPS. Most premium factories run SPQ-FR exclusively to standardize their cutting line.

What is the ATEX certification scope?

ATEX zone-22 covers the entire cutting cell (cutting frame + dust extraction + electrical cabinet) per EN 60079-31 and EN 1127-1. Certification ships with machine. Customer's factory environment also needs to be ATEX-zoned if processing graphite — we provide site survey checklist.

What HEPA filter spec, and replacement frequency?

HEPA H13 (99.95% efficiency at 0.3 micron) — captures graphite dust safely. Filter replacement every 6-12 months depending on graphite load. Spare filter kit ships with machine.

Does the slower cutting speed (0.5-1.2 m/min vs 0.6-2 on SPQ-B) hurt throughput?

Effective throughput is comparable because graphite-EPS sells at 1.5-2× the price of standard EPS — slower cut speed is offset by higher margin per sheet. Most SPQ-FR operators run 15-20 t/day vs 25 t/day on SPQ-B but make 2-3× the revenue.
