O Que Esta Máquina Resolve

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

O Problema

Automotive EPP bumper-system production requires steam pressures (0.5-0.8 MPa) that standard EPS pre-expanders cannot deliver — using EPS machines damages EPP material

Como Esta Máquina Resolve

SPEPP-2F is purpose-built for EPP with higher-pressure barrel (0.5-0.8 MPa rated) and reinforced agitator for EPP's higher-viscosity expansion behavior.

O Problema

EPP density windows (15-90 kg/m³) are 3× wider than EPS — generic pre-expanders cannot hold the precision automotive Tier-1 customers demand

Como Esta Máquina Resolve

SPEPP-2F has EPP-specific recipe library on the HMI — pre-engineered parameter sets for automotive bumper grades (35-50 kg/m³), sporting-goods grades (50-70), and packaging grades (15-30).

O Problema

EPP cycle times (6-10 min) are longer than EPS — operators waste shift time waiting for batch completion

Como Esta Máquina Resolve

SPEPP-2F's 38 kW heating + closed-loop steam control minimizes cycle time within EPP's physical constraints — 6-7 minutes typical vs 8-12 on retrofitted EPS machines.

Princípio de Funcionamento

SPEPP-2F is a secondary foaming machine — EPP beads have already been primary-foamed by raw material supplier; SPEPP-2F performs the secondary expansion that gives EPP its final density. Higher steam pressure than EPS (0.5-0.8 MPa) is what enables EPP's elevated thermal requirements.

Step 1

1. EPP Bead Loading

Primary-foamed EPP beads loaded via electronic weighing batch loader.

Step 2

2. High-Pressure Steam Pre-heat

Barrel pre-heated by saturated steam at 0.5-0.8 MPa working pressure (vs 0.18-0.25 on EPS).

Step 3

3. Secondary Expansion

Steam injected for 4-6 minutes; beads expand to final EPP density (15-90 kg/m³ range).

Step 4

4. Cooling & Stabilization

Vacuum + water-spray cooling stabilizes bead structure before discharge.

Step 5

5. Pneumatic Discharge

Expanded EPP beads conveyed to aging silo for 24-72h moisture/pressure stabilization.

Vantagens de Desempenho Engenheiradas

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

Steam Pressure Rating
0.5-0.8 MPa
vs EPS pre-expanders 0.18-0.25

3-4× higher pressure capability for EPP's elevated requirements.

Density Range
15-90 kg/m³
vs EPS 8-30 kg/m³

3× wider density range covers automotive, sporting, and packaging EPP grades.

Recipe Library
EPP-specific
vs generic = 0

Automotive bumper, sporting goods, packaging recipes pre-stored on HMI.

Cycle Time
6-10 min
vs retrofitted EPS 8-12 min

Higher heating capacity minimizes cycle time within EPP physical constraints.

Automotive Qualification
OEM-grade
vs EPS machines don't qualify

Steam pressure + recipe precision meets automotive Tier-1 supplier requirements.

Product FAQ

The questions buyers ask most often before placing an order.

Why can't I use my existing EPS pre-expander for EPP?
Two physical reasons. (1) Steam pressure: EPP needs 0.5-0.8 MPa, EPS pre-expanders are rated for 0.18-0.25 MPa — running at higher pressure exceeds the pressure vessel certification and risks rupture. (2) Agitator: EPP has higher viscosity during expansion, EPS agitators are sized for lower torque — running EPP destroys agitator seals within months.
Does SPEPP-2F also work for EPS?
Yes — backward compatible, just run at lower steam pressure (0.18-0.25 MPa range). But it's overkill for EPS-only production — EPS pre-expanders are 30-40% cheaper.
What automotive certifications does SPEPP-2F support?
IATF 16949 compatible (automotive supplier quality system). The machine itself is CE + ISO 9001 certified; your factory needs to add IATF 16949 process certification separately. We provide documentation supporting IATF audits.
Steam boiler requirement?
Minimum 1.0 ton/h at 1.0 MPa working pressure. Higher boiler spec than EPS due to EPP's elevated steam requirements.
Ships to 220V/60Hz?
Yes — factory build option. 3-week lead time adjustment for the larger motor sourcing.
