Ce que Cette Machine Résout
Trois problèmes de production éliminés par cette machine — avec des solutions ingénieriques et mesurables.
Le Problème
Un cycle de moulage de formes de 60-90 secondes plafonne la production journalière et gonfle le coût à la pièce
Comment Cette Machine le Résout
Le serrage hydraulique du SM-1200 et la circulation fermée de vapeur permettent des cycles de 35-50 secondes pour le moulage de caisses à poisson et d'inserts d'emballage — production en hausse de 50-70 %.
Le Problème
Les condensats piégés provoquent des pièces humides et déformées qui échouent au contrôle qualité
Comment Cette Machine le Résout
Doubles ports de séchage sous vide et drainage automatique des condensats délivrent une humidité résiduelle ≤0,5 % dans la pièce finie ; le taux de rejet QC tombe sous 1,5 %.
Le Problème
Les changements fréquents de moules pour différentes références coûtent 2-4 heures à chaque fois
Comment Cette Machine le Résout
Plateau de moule à changement rapide et interface de serrage standardisée réduisent le changement de moule à moins de 45 minutes — la production en petites séries devient économique.
Inside the Machine — Core Components
Eight engineered subsystems that make this cutting line production-grade. Each component is sourced, built, and tested for industrial duty cycles.
1. Shape Mold Cavity (1,200×1,000mm Platen)
Function
The custom-shaped mold cavity that defines the finished product geometry. Unlike BM-1400 which makes one standard block shape, the SM-1200 accepts dozens of different cavity inserts for fish boxes, cooler boxes, packaging inserts, automotive parts.
Engineering Details
Mold platen 1,200×1,000mm accommodates products up to 1,150×950×350mm. Cast aluminum cavity inserts (machined from solid billet for premium products, sand-cast for cost-sensitive products). Quick-change locking system — 4-6 hour mold swap.
2. 25-Ton Hydraulic Clamping System
Function
Closes the mold under sufficient force to contain steam pressure during fusion and prevent flash on the visible product surface. Critical for visible packaging where any flash = customer reject.
Engineering Details
Single hydraulic cylinder rated 25 tons. Closing speed 80-120 mm/s with cushioned approach for delicate mold protection. Pressure-hold during steam phase with safety interlock against unauthorized opening.
3. Cast Aluminum Mold Cavity Inserts
Function
The interchangeable working surface that gives each product its final shape. Cast aluminum is preferred over steel for shape molds because it heats and cools faster (shorter cycles) and weighs less (easier changeover).
Engineering Details
Cast or CNC-machined 6061 aluminum. Engineered steam channels for uniform heating across complex shapes. Surface anodized for durability + clean release. Vent pin holes (0.5mm) prevent air-trap defects. ChinaEps engineers custom molds in 6-8 weeks lead time.
4. Pneumatic Bead Fill Gun
Function
Loads pre-expanded EPS beads into the mold cavity through multiple injection nozzles. Uniform fill is what determines uniform product density — voids and density gradients come from fill problems, not steam problems.
Engineering Details
4-8 pneumatic injection guns (count varies by mold size). Air-assist 0.3-0.5 MPa adjustable on HMI. Anti-static design prevents bead clumping. Material level sensors confirm fill completion before clamping cycle.
5. Multi-Zone Steam Injection Chamber
Function
Distributes saturated steam from the perforated steam plates surrounding the mold cavity. Multi-zone control compensates for asymmetric mold geometry — one side may need more steam than the other.
Engineering Details
316 stainless steam plates with engineered hole pattern. Independent PLC-controlled steam zones (2-4 zones depending on mold size). Working pressure 0.08-0.12 MPa closed-loop regulated. Steam condensate drain at each zone low point.
6. Vacuum Cooling System
Function
Pulls vacuum on the mold cavity to evaporate residual moisture from the product surface. Vacuum cooling is the single biggest factor in 60-90 second cycle times — air-cool would push cycles to 150-200 seconds.
Engineering Details
Built-in water-ring vacuum pump (7.5 kW Becker/Edwards equivalent). Vacuum tank acts as buffer for quick cycle pulldown. Reaches 0.06 MPa absolute pressure in 30-45 seconds. Combined with water-spray cooling, achieves 30-40% faster cycle vs air-only.
7. Dual-Stage Product Ejection
Function
Removes the finished product from the mold cavity without damaging the surface. Two-stage (hydraulic break + pneumatic eject) prevents the sudden release that tears the mold-release coating.
Engineering Details
Hydraulic mold-open breaks the cavity seal at low speed. Pneumatic ejector pins push product out at controlled speed. Adjustable ejection pressure 0.2-0.5 MPa on HMI. Product counter on HMI tracks daily output.
8. PLC Control & HMI
Function
Supervises the full cycle (fill → steam → vacuum cool → eject) with recipe-based control. Stores production recipes per product SKU for quick changeover.
Engineering Details
Siemens S7-1200 PLC + 10" Weintek HMI. Recipe library for 30+ product variants. USB recipe export; optional Ethernet/IP for MES integration. Local fault log retains 1,000 events. Multi-user accounts (operator/supervisor/maintenance) with audit trail.
Principe de Fonctionnement
Le SM-1200 est une mouleuse de formes automatique pour pièces EPS/EPP sur mesure. Les billes pré-expansées sont chargées dans une cavité de moule fermée ; la vapeur saturée fusionne les billes selon la forme finale de la pièce ; le séchage sous vide élimine l'humidité ; le serrage hydraulique libère la pièce refroidie. Les 1 200 désignent la taille du plateau en mm.
Step 1
1. Fermeture du Moule
Le serrage hydraulique ferme les demi-moules à 25 MPa de pression de service.
Step 2
2. Remplissage des Billes
Injecteurs pneumatiques remplissent uniformément la cavité par plusieurs portes.
Step 3
3. Chauffage Vapeur
Vapeur saturée 0,15-0,20 MPa fusionne les billes en 15-25 s.
Step 4
4. Vide & Refroidissement
Doubles ports de vide éliminent l'humidité ; l'eau de refroidissement abaisse la pièce à 50 °C.
Step 5
5. Éjection
Le moule s'ouvre ; les éjecteurs pneumatiques poussent la pièce finie.

Product FAQ
The questions buyers ask most often before placing an order.
How is the SM-1200 different from the BM-1400 block-molding machine?
Three categories of difference. (1) Output: SM-1200 makes finished-shape products (fish boxes, cooler boxes, packaging inserts) ready for sale; BM-1400 makes blocks that need a downstream cutting step. (2) Mold: SM-1200 uses custom cavity inserts (one per product SKU); BM-1400 uses one standard block cavity. (3) Cycle: SM-1200 60-150 seconds per part; BM-1400 5-7 minutes per block. Use SM-1200 for finished-shape packaging and consumer products; use BM-1400 for cut-to-size insulation and geofoam.
What products can be made on a single SM-1200, and how long does mold changeover take?
Any finished EPS shape that fits within the 1,200×1,000×350mm work envelope. Common: fish boxes, cooler boxes, fruit-tray inserts, helmet liners, automotive bumper inserts, refrigerator cushions. Mold changeover 4-6 hours with the quick-change locking system. Most customers run 3-8 different SKUs per machine.
How are custom molds designed and made — what is the lead time?
Customer provides 3D CAD file (STEP or IGES format) of the desired finished product, or a physical sample we can reverse-engineer. ChinaEps engineering does mold design (1-2 weeks), customer approves, then mold manufacturing (4-6 weeks). Total custom mold lead time 6-8 weeks. Cast aluminum is standard; cost varies USD 5,000-25,000 depending on product complexity.
What bead density range does the SM-1200 handle, and how does cycle time scale?
15-50 kg/m³ density range. Lower density (15-20 kg/m³ — typical for fish boxes and lightweight packaging) cycles 60-90 seconds. Mid-density (25-30 kg/m³ — automotive parts) cycles 100-130 seconds. Higher density (40-50 kg/m³ — premium FR-grade) cycles 130-150 seconds.
Can the SM-1200 work with EPP and fast-cycling EPS beads?
Yes — both. EPP requires slightly higher steam pressure (0.10-0.14 MPa) and longer cycles (15-25% more time). Fast-cycling EPS reduces cycle time 20-30% — particularly attractive for high-volume cooler-box producers. Mold material (aluminum) and clamping system are compatible with all bead types.
What is the steam boiler requirement?
Minimum 0.5 ton/h steam boiler at 0.15 MPa working pressure. Most customers run a 1.0 ton/h boiler to cover SM-1200 + upstream PE-1400 pre-expander + downstream operations. ChinaEps can quote the matching boiler + softener + condensate-return system.
Can the SM-1200 ship to 220V/60Hz markets?
Yes — factory build option. We swap hydraulic pump motor, vacuum pump motor, contactors, and VFD to 220V/60Hz equivalents. PLC and HMI are voltage-flexible. No price difference; 2-3 week lead time adjustment.
How many pieces per day, and how does that scale with product type?
At 90-second cycles (typical fish boxes): 40 cycles/hour × 8 hours = 320 cycles per shift. Multi-cavity molds (4-up or 6-up for small products) push this to 1,200-2,000 pieces/shift. Double-shift operation reaches 24,000+ pieces/day on small products like fruit-tray inserts.
What is the integration path with PE-1400 and downstream operations?
Standard line: PE-1400 → aging silo (24-72h) → SM-1200 → automated stacker (ST1200) → wrapping machine (SPLM). The SM-1200 PLC has analog/digital I/O for upstream/downstream handshaking. Most line integrations complete in 5-7 days on-site.
What is the operator training requirement?
Two options: (1) factory training in Qingdao for 2-3 days during pre-shipment testing (you cover travel); (2) on-site training for 3-5 days during commissioning (you cover travel + accommodation). Training covers PLC recipe management, mold changeover, troubleshooting common defects, and maintenance schedule. Materials in EN / ZH / ES / PT / FR / RU / AR.
Is the SM-1200 the same as a thermocol making machine?
Yes. "Thermocol" is the common name for EPS (expanded polystyrene) in India and South Asia, so a thermocol making machine and an EPS shape molding machine are the same equipment. The SM-1200 covers the full thermocol product range — disposable tableware, sheets, boxes, and decorative items. We ship to thermocol manufacturers across India, Bangladesh, Sri Lanka, and Nepal with CE certification and a 5-year warranty.
Can the SM-1200 make thermocol plates, cups, and dona?
Yes. The SM-1200 thermocol making machine produces thermocol plates, cups, dona (disposable bowls), trays, and boxes by steam-fusing EPS beads in custom aluminium molds. A single SM-1200 with a multi-cavity dona/plate mold produces 200-400 thermocol items per hour; swap molds in under 45 minutes to switch between thermocol plate making, cup making, and dona making on the same machine. We supply the complete thermocol plate making machine line — pre-expander, SM-1200 shape molder, and your choice of plate, cup, or dona molds.
