EPS Block Machine

Features and advantages of products: 

1、Energy saving: The ordinary light shape moulding machine produce 1 ton light board at the density of 4 kg/M3 needs 4.4-5.5 tons of steam. Our machine saves 30-50% of energy to produce light board, and it just needs 2-2.5 tons of steam on average. 

Pipes and steam holes: Specially designed pipes and steam holes can save energy.
Heat preservation: the heat preservation design of the outer door panel, better heat preservation, saving heat energy, balanced temperature in the board machine, and better product quality.

2、The plate has fast forming speed, good adhesion and uniform density which can reach 6-45kg/ m3. 

3、The machine can be equipped with touch screen, automatic conveying deviceautomatic electronic weighing and printing device. 

4、The machine can be matched with color steel sandwich panels to produce 850mm, 950mm and 1150mm, as so as 1000mm building plates.

Strong Machine Structure:

1. Main machine frame is welded by high-quality profile steel plate and strong rectangular tubes , ensure a strong machine structure from the base .

2. Processed by heating-treatment to release the welding stress, the machine frames is with high strength, non-deformation, and with and high resistance to the expansive force from high-density products.

3. In order to keep the rust away ,the machine will be processed by shot blast treatment or sand treatment . Then it is painted by several times anti-rust bottom painting and several times of anti-rust surface painting , which will achieve very good anti-corrosion performance and make the whole block molding machine with a longer lifetime .

4. The surface of the mould is made of special aluminum alloy panel or stainless steel sheet which can realize a high efficiency of heat conduction, favorable tensile strength and long service life.

Steam System:

The EPS Block Machine is integrated with overseas advanced and special penetrating and heating techniques for shaping, and a high pressure suction fan for material feeding, cooling with a strong penetrability, favorable adhesivity, low consumption of steam, high speed of shaping and low water content so as to ensure the uniformity of inside and outside of the product.

Pre Expander Machine

Product features:

Features of Factory direct sale high quality batch EPS pre expander

1. PID control system

Automatic PID adjusting and control system, temperature sensor automatic feedback. PID steam and compressed air automatic adjusting to achieve different steam temperature for different density requirement. Temperature tolerance is ±0.2, temperature remain stable. It achieves constant temperature and constant pressure foaming, ensure the foamed beads density evenly, foaming accuracy ±1%.

2. Weighing closed-loop feedback system

Weighing feedback system adopts famous brands dedicated weighing controllers, controlled by PLC and touch screen. The weighing system can accurately weigh the foamed beads weight, give feedback in time. By adjusting feeding material weight to control the foam density accuracy.

3. Vibration level sensor control system

It adopts Germany imported vibration level sensor to control the foaming beads level to achieve accurate volume control, then ensure foaming density accuracy.

4. Vacuum drying system

1) Vacuum drying system adopts vacuumize drying method, drying forming time short, ensure foaming more uniform & accurate and ensure clean discharging, when weighing samples will not confuse and feedback is accurate.

2) Discharging valve is fine butterfly valve, ensure the vacuum degree when come into drying system and discharging in time.

5. Weighing feeding system

The weighing feeding system adopts famous brands dedicated weighing controllers and load cell, controlled by PLC and touch screen.The weighing system can accurately control the raw material input to realize the minimum deviation.

6. Pre-foaming system

1) The barrel is made by high quality stainless steel, ensure the circular degree and strength.

2) The main stirrer of the barrel adopts frequency control, the main shaft revolving speed can be adjustable, better guarantee for raw material heating evenness.

3) Perforated bottom plate with fine stainless steel 316 special material and structure, ensure steam penetrating more smoothly and evenly during heating, then foam density more stable, each bead more evenly, and reducing steam consumption. Thus it can save more raw material cost and energy cost.

4) Foaming level control adopts Germany imported vibration level sensor, could perceive foaming beads rising situation, keep foaming density tolerance minimum.

5) Discharging door fine processed in CNC machining center and fine assembly, ensure move stable during working, avoid material crowded or discharging door deforming.

7. Crushing and screening system

1) Crushing and screening system adopts horizontal paddle structure, working more stable, crushing and screening effective better.

2) Feeding system adopts the principle of closed-air aspirator, keep away from the air from the feeding fan, make the feeding faster and in time.

8. Electric control system

1) Valves are imported from Germany.

2) Electrical element are imported from Germany and Italy.

3) Its operation is simple and easy. Feeding weight and all relevant parameters can be adjusted and self-saved according to

different material and density. The weighing feedback system can weighed every batch foamed beads weight accurately and give feedback timely to adjust next feeding weight.

4) Friendly human-computer interface, touch screen control system could automatically detect faults and alerts their location and repair method, ensure maintaining easy and fast.
