Machine Capacity:
Small (entry / semi-auto): ±1,200–1,500 pcs/hour for small electronic packaging (small home appliances).
Medium (rotary 4–6 side): 3,000–6,000 pcs/hour (industrial tray/inner-pack format). model & mould.
Large (rotary 6–8 side): 6,000–10,000+ pcs/hour for bulk output & multi-products/shift.
Alternative vendor specs by mass: some vendors state 120–150 kg/hour per forming machine specifically for “Electronic
Package Pulp Tray” (rather than pcs/hour), with a 2,400×800 mm platen & single-layer dryer. This is common for parts with varying grammage/volume.
Production Process:
Pulp Preparation:
Hydrapulper + screening + cleaner (cyclone) to remove contaminants; additive dosing system (stiffener/anti-fungal/anti-static optional).
Raw material: ONP/OCC/office waste; anti-static / moisture-resistant additives are relevant for sensitive electronics (optional).
Forming (wet):
Type: vacuum forming; reciprocating (entry) or rotary (4–8 side) for high throughput. Rotary = volume class; reciprocating = small batch class.
Platen/Mould: example 2,400×800 mm (reciprocating electronics) or other vendor formats 450×1200 mm; 3–6 moulds/side is common for industrial trays.
Product height: up to ≤160 mm (depending on tray design & air/vacuum circulation).
Dryer:
Recommendation: multi-layer zoned metal dryer (NG/LPG/diesel/steam). Stable for 24/7 and thick/ribbed products. Economical alternative: brick/natural dryer (weather dependent, slower output).
Hot-press (very important for electronics):
Function: tidying the surface, locking dimensions, increasing edge stiffness/component fit. Used specifically for premium
electronics packaging. Can be online (automatic) or a separate semi-hotpress.
Utilities, Space, and Labor:
Electrical power (small class ±1.4k pcs/hour): running ~70 kW, installed ~100 kW; workshop ±300–350 m².
Electrical power (medium class 3–6k pcs/hour): depends on dryer length & number of sides; typically increases significantly
compared to the small class (rotary + multi-layer dryer). Vendor references mention rotary machines are indeed for 6–7–10k pcs/hour.
Daily output (example 4-side): commercial documents mention ~50–57 thousand pcs/day for mass-produced trays (egg/fruit/bottle) — comparable figures for electronics if grammage & drying are similar.
Labor: 3–5 people/shift (small–medium class), increasing for large lines/multi-dryers.
Product Specifications & Quality (for electronics):
Product type: inner-pack, end-cap, corner/edge protector, cradle tray (laptop, router, printer, small appliances).
Surface & tolerance: use hot-press for a smoother surface & stable dimensions (fit to housing/carton).
Special additives: anti-static/moisture-resistant as required for ESD and distribution climate needs.
