The chemical and petrochemical industry places special requirements on equipment: aggressive environments, specific storage conditions, and elevated safety standards. Nevertheless, this is precisely where palletizing automation delivers the maximum economic effect — while reducing risks to personnel.
🏭 The chemical industry is the second-largest market for palletizers globally, after food and beverage. The volume of produced goods requiring palletizing exceeds 400 million tons annually worldwide.
Typical Palletizing Tasks in the Chemical Industry
| Product | Packaging | Unit Weight | Recommended Model |
|---|---|---|---|
| Fertilizers (urea, MAP/DAP) | Bags 50 kg | 50 kg | WSC-MD60 / MD80 |
| Polymers (granules) | Bags 25 kg | 25 kg | WSC-MD40 |
| Paints and coatings | Pails, canisters | 10–25 kg | WSC-MD25 / MD40 |
| Industrial fluids | Canisters, drums | 20–60 kg | WSC-MD60 |
| Construction chemicals | Bags, pails | 20–40 kg | WSC-MD40 |
Equipment Requirements in Chemical Environments
1. Protection from Aggressive Media (IP54 and above)
At fertilizer, acid, and solvent production facilities, equipment is exposed to vapors, dust, and moisture. The WSC-MD collaborative robot features IP54 protection, ensuring reliable operation in dust-protected environments and splash resistance.
2. Corrosion-Resistant Housing Materials
The WSC-MD housing and base are made from stainless steel; the manipulator uses a magnesium-aluminum alloy and carbon fiber composite. This provides a lightweight construction with high strength and resistance to aggressive media.
3. Working with Bag Packaging: Special Requirements
Soft bags with powdered or granular products are one of the most demanding tasks for a palletizer. Key requirements:
- Gripping without damaging the bag (vacuum or mechanical jaw gripper)
- Maintaining bag shape during stacking
- Stable pallet height — up to 1.8 m for high-bay warehouses
- Alternating stacking patterns for stable stacking
⚠️ Important: When working with bags exceeding 50 kg, the WSC-MD60 or MD80 model is required. Overloading reduces accuracy and equipment service life.
4. Personnel Safety — the Main Argument
Palletizing bags of chemical products is physically demanding and potentially dangerous work. The WSC collaborative robot works without a safety fence, stopping when a person enters the work area, meeting modern safety standards.
Case Study: Fertilizer Bag Palletizing
A nitrogen fertilizer production facility (output 200 bags of 50 kg/hour) deployed WSC-MD60 on the packaging line. Previously, 4 workers on two shifts handled palletizing.
| Metric | Before | After |
|---|---|---|
| Palletizing speed | 180 bags/hour | 220 bags/hour (+22%) |
| Stacking defects | 2.1% | 0.1% |
| Workplace injuries per year | 3 incidents | 0 |
| Department payroll | $3,700/month | $520/month |
| Payback period | 11 months | |
How Distributors Can Reach Chemical Facilities
The chemical industry is conservative about equipment selection, but has characteristics that make sales predictable:
- Centralized purchasing — decisions are made at the chief engineer or production director level
- Long-term contracts — facilities prefer reliable suppliers with service support
- Regulatory pressure — tightening occupational safety requirements drive automation of hazardous areas
- Fertilizer seasonality — peak palletizer sales occur in January–March (pre-season preparation)
