1 Automation Pain Points in the Large-Scale Packaging Injection Molding Industry
Large-scale packaging injection molding is generally characterized by long strokes, heavy loads, long cycles and multi-process collaboration. Traditional manual operation or simple 3-axis equipment cannot meet the requirements of stable mass production:
- Large-sized and heavy products lead to low manual picking efficiency, high safety risks, and easy scratching or deformation of products.
- Thick-walled parts require long cooling time and strict cycle control, which cannot be stably matched by manual work.
- Processes such as in-mold labeling, sprue cutting and stacking require multi-directional movements, while 3-axis robots lack sufficient degrees of freedom.
- Strong demand for fast product changeover results in high production line switching costs due to insufficient equipment flexibility.
- 24-hour continuous workshop production puts forward strict requirements on equipment stability, failure rate and maintenance costs.
These pain points directly increase production costs and reduce yield and delivery capacity, which can be solved systematically by 5-axis servo robots.
2 Core Advantages of 5-Axis Servo Robots for Large-Scale Packaging Injection Molding
Adopting full servo drive for X/Y/Z/R1/R2 five axes, 5-axis robots have irreplaceable advantages compared with traditional 3-axis solutions in large-scale packaging scenarios:
- Full-range flexible movement: Support posture adjustment with vertical, horizontal, longitudinal and dual rotating axes, suitable for picking and repositioning deep-cavity, undercut and special-shaped large packaging parts.
- Heavy load and long stroke: Single machine load ranges from 15kg to 50kg, compatible with 650T to 1800T large Injection Molding Machines, meeting the demands of pallets, chemical barrels, large food containers and other products.
- High-precision positioning: Repeated positioning accuracy reaches ±0.1mm, ensuring the consistency of precision processes such as in-mold labeling and embedding.
- High-speed cycle: The servo system features fast response, shortening the picking and transferring time by 30% to 50%, and increasing daily output per machine.
- Multi-process integration: One piece of equipment completes picking, sprue cutting, flipping, stacking and box packing, reducing labor and auxiliary equipment.
- Stable and reliable: Capable of 24-hour continuous operation with low failure rate, suitable for dark factories and mass production for export orders.
- Fast product changeover: Parameter storage and one-click calling support completing the switch of different packaging specifications within 10 minutes.
3 Typical Application Scenarios of 5-Axis Robots in Large-Scale Packaging Injection Molding
5-axis robots have been deeply applied in the whole process of large-scale packaging injection molding, covering mainstream products and processes:
- Large food container injection molding Fully integrated picking, sprue cutting, stacking and conveying for fresh-keeping boxes, lunch boxes, milk tea cups and food buckets to improve cleanliness and yield.
- In-mold Labeling (IML) for large packaging The dual rotating axes of 5-axis robots realize precise label positioning, integrating labels with plastic parts during molding without post-printing, enhancing appearance and efficiency.
- Industrial logistics packaging Stable picking and palletizing for plastic pallets, logistics boxes, chemical barrels and other heavy packaging products with heavy-load 5-axis robots to eliminate manual risks.
- Thick-walled packaging automation Support cooling delay, posture adjustment and anti-deformation grabbing for large water buckets, fuel tanks and daily chemical packaging to improve qualification rates.
- Multi-cavity and stack mold large packaging Dual-arm synchronous picking and split placement in multi-cavity and stack mold scenarios greatly boost output per unit time.
- Post-process integrated connection Connect with conveyor belts, visual inspection machines, box packers and palletizers to form a complete production solution integrating injection molding, automation and packaging.
