Equipment Requirements:
- Mixer should ensure uniform mixing, no dead zones, and a good drainage system.
- Temperature control must be accurate with reliable sensors.
- Dust removal and dehumidification systems are essential.
Extrusion equipment should:
- Achieve good dispersion of wood powder, resin, and additives.
- Have proper mixing without excessive shear force.
- Feature precise temperature control.
- Include an efficient exhaust system for dehydration and bubble removal.
- Use wear-resistant materials for screws and barrels.
Mold requirements:
- Special design for wood-plastic hangers.
- No dead zones with accurate control.
- Accurate temperature regulation.
4. Plant Structure and Hydropower Installation:
- Workshop height: minimum 4 meters; length: 35 meters; width: 6 meters.
- Mixing workshop and warehouse area: at least 12m x 6m.
- Total plant area: not less than 1500 square meters.
- Cooling tower (30 tons) installed outdoors in a 16 sqm area, at least 1m high, connected to indoor pipelines.
- Main pipes: 2 or 3-inch steel pipes depending on pump inlet.
- Drain pipes: 110mm PVC pressure pipes.
- Cooling water flow: 5–8 tons/hour.
- Drainage ditches must follow the layout diagram.
- Total power for one line: 300 kW.
9. Waste Formula:
- Basic materials: waste PVC, wood flour, calcium carbonate, stabilizers, and foaming agents.
2. Cost Calculation:
- Building template cost per ton: ¥5,500 (based on waste).
- Daily output: 6 tons per line (actual manufacturers may have more lines, reducing costs).
- A: Material cost = ¥5,500/ton
- B: Power cost = (mixer 1000 kWh + extruder 3800 kWh) ÷ 6 tons × 0.8 yuan/kWh = ¥548/ton
- C: Management fee = ¥600/day ÷ 6 tons = ¥100/ton
- Total cost per ton = A + B + C = ¥6,285/ton
3. Ex-factory price: ¥9,375/ton
- Based on Huangshi Hongtai Board's August 2011 pricing: 150 yuan/piece for 1830×915×15mm board, weighing 16 kg/piece → ¥9,375/ton.
4. Profit per ton: ¥3,875 (gross) = 9,375 – 5,500
- Net profit after deducting labor and electricity: ¥2,875/ton.
5. Annual profit for one line: ¥4.5 million = 6 tons/day × 300 days × ¥2,500/ton.
Note: Raw material cost per ton is ¥5,500, making up 65% of total cost. A 36 ft (1830×915×12) board weighs 16 kg, costing ¥88 in raw materials, while selling at ¥150 per piece.
