Comprehensive Guide to Jerrycan Production Equipment
Jerrycan (Fuel Can/Storage Drum) production primarily falls into two categories: plastic and metal, with significant differences in core equipment and processes. Below is a detailed breakdown:
I. Core Production Equipment for Plastic Jerrycans
Plastic Jerrycans (mostly HDPE material) adopt the extrusion blow molding process, which is currently the mainstream in the market.
1. Core Molding Equipment
| Equipment Type | Application Range | Key Features |
|---|---|---|
| Single-station Extrusion Blow Molding Machine | Small Jerrycans (1-10L) | Simple structure, low cost, suitable for small-batch production |
| Dual-station Extrusion Blow Molding Machine | Medium Jerrycans (5-20L) | Higher efficiency, continuous production capability, output: ~130-140pcs/hr (20L model) |
| Multi-layer Co-extrusion Blow Molding Machine (2-3 layers) | Chemical/hazardous material packaging | Excellent barrier performance, anti-permeation, ideal for special protection needs |
| Accumulator Head Blow Molding Machine | Large Jerrycans (20-30L) | Suitable for producing large hollow products with uniform wall thickness, stable pressure |
Core Components:
- Plasticizing System: American S-design series screw for sufficient plasticization of HDPE and other materials
- Extrusion Head: Customizable single/multi-die head for parison thickness control
- Clamping Unit: 70-200kN clamping force to ensure tight mold closure
- Blowing System: 0.6MPa air pressure to make the parison adhere to the mold cavity
2. Auxiliary & Post-processing Equipment
| Equipment Name | Function |
|---|---|
| Automatic Deflashing Machine | Removes excess plastic flash after blow molding, improving product appearance |
| Leak Testing Machine | High-pressure/vacuum testing to ensure zero leakage (critical safety indicator) |
| Automatic Labeling Machine | Applies product labels and specification information, compatible with 5-20L sizes |
| Conveyor System | Connects processes for automated assembly line production |
| Raw Material Dryer | Removes moisture from HDPE raw materials to prevent bubbles in products |
| Crusher | Recycles production scrap to reduce costs |
3. Typical Production Line Configuration
Complete plastic Jerrycan production line:
Raw Material → Dryer → Extrusion Blow Molding Machine → Deflashing Machine → Leak Testing → Labeling → Packaging → Finished Product Storage
II. Core Production Equipment for Metal Jerrycans
Metal Jerrycans (traditional military/industrial use) adopt the stamping + welding process.
1. Core Molding Equipment
| Equipment Type | Function | Key Parameters |
|---|---|---|
| CNC Laser Cutting/Plasma Cutting Machine | Cuts metal sheets (tinplate/stainless steel) | High precision, smooth cuts, suitable for complex shapes |
| Large Stamping Machine | Stamps can body, bottom, and lid | 100-500 tons pressure, one-step molding of complex curved surfaces |
| Resistance Welding/Laser Welding Machine | Welds can body seams and handles | High weld strength, leak-proof, ideal for metal containers |
| Curling/Capping Machine | Seals can mouth and bottom | Ensures sealing performance, compatible with various threaded caps |
2. Surface Treatment & Post-processing Equipment
| Equipment Name | Function |
|---|---|
| Cleaning Machine | Removes welding oil and impurities, preparing for coating |
| Powder Coating Equipment | Applies anti-corrosion coating (e.g., epoxy powder) to enhance corrosion resistance |
| Drying Oven | Cures coatings for improved adhesion |
| Pressure Testing Machine | Tests container pressure resistance, complying with UN transport standards |
III. Universal Auxiliary & Testing Equipment
Both plastic and metal Jerrycan production require the following equipment:
| Equipment Category | Specific Equipment | Testing Items |
|---|---|---|
| Quality Testing | Wall Thickness Gauge | Ensures uniform wall thickness and meets strength requirements |
| Drop Test Machine | Simulates transportation impact to test shock resistance | |
| Stacking Test Machine | Tests stacking load capacity (typically ≥200kg) | |
| Seal Tester | High-pressure/vacuum testing to ensure zero leakage | |
| Packaging Equipment | Automatic Cartoning Machine | Packs finished products into cartons for efficient packaging |
| Stretch Film Wrapping Machine | Palletizes products for easy storage and transportation | |
| Weighing & Labeling Machine | Records weight and applies traceability labels |
IV. Key Factors for Equipment Selection
- Production Capacity Requirements:
- Small-scale production: Single-station blow molding machine (100-200pcs/hr)
- Medium-scale production: Dual-station blow molding machine (300-500pcs/hr)
- Large-scale production: Multi-layer co-extrusion blow molding machine + automated production line (800-1200pcs/hr)
- Product Specifications:
- 1-10L: Extrusion blow molding machine with 75mm screw diameter
- 10-20L: Extrusion blow molding machine with 90-100mm screw diameter
- 20-30L: Accumulator head blow molding machine
- Material Characteristics:
- HDPE/PP materials: Standard extrusion blow molding machine suffices
- Chemical packaging: Multi-layer co-extrusion equipment (barrier layer + recycling layer) is mandatory
V. Typical Equipment Recommendations & Price Reference (USD)
| Equipment Type | Model Example | Price Range | Applicable Products |
|---|---|---|---|
| Single-station Blow Molding Machine | LBH75D | $19,800-$29,800 | 5L Jerrycan |
| Dual-station Blow Molding Machine | HSII-15L/1 | $49,999-$65,999 | 20L Jerrycan |
| 3-layer Co-extrusion Blow Molding Machine | 90D-30L | $78,000-$95,000 | Chemical packaging Jerrycan |
| Metal Stamping Production Line | JORSON 20L | $150,000-$200,000 | Metal military Jerrycan |
Summary
Plastic Jerrycans rely on extrusion blow molding machines as the core, offering high production efficiency, low cost, and light weight. Metal Jerrycans use stamping + welding equipment, providing high strength and resistance to extreme environments. Equipment selection should be based on product material, specifications, capacity, and application scenarios. Additionally, comprehensive testing equipment is essential to ensure compliance with UN transport standards and industry regulations.
