Sepro Robots: A Complete Guide to Injection Molding Automation
Sepro Group is a global leader in the design and manufacture of Cartesian robots specifically for the plastics industry. Founded in 1973 and headquartered in France, the company has equipped over 40,000 injection molding machines worldwide with advanced automation solutions. 🤖 Diverse Robot Portfolio
Sepro offers a wide range of robots categorized by their axes of motion and the size of the injection molding machine (IMM) they serve. 3-Axis Cartesian Robots robot sepro
These are the industrial workhorses for standard part removal and stacking.
Success Line: A universal range for machines from 20 to 900 tons, designed for simple, reliable performance.
Strong Line: Focused on large IMMs (700 to 2800 tons), providing an economical solution for straightforward unloading.
S7 Line: The "technological" range for large machines up to 5000 tons, featuring high-speed performance and modular axis design. 5-Axis Servo Robots
For complex parts requiring precise orientation, these robots add a 2-axis servo wrist to the standard 3-axis platform.
If your injection molding shop runs more than 2,000 hours per year, and you make parts that weigh between 0.05 lbs and 220 lbs, then a Robot Sepro is a strategic investment.
Sepro’s combination of molding-specific engineering, powerful yet simple Visual Control, and global service network makes it the top choice for molders who want to move from manual or pneumatic part removal to full servo automation.
Before buying, ask your Sepro distributor for a site cycle simulation and a 4-week ROI calculation. Most molders find that the robot pays for itself within 12-18 months through labor savings, reduced scrap, and improved consistency.
The industrial robotics market includes giants like Fanuc, ABB, and Yaskawa. However, Sepro holds a unique advantage: deep injection molding expertise.
Sepro recognized early that Cartesian robots have physical limits when dealing with undercuts or complex post-molding operations. Their partnership with Yaskawa and Stäubli led to the 6-Axis Robot Sepro line.
Q: Can a Sepro robot be installed on any injection molding machine? A: Yes, Sepro provides mounting brackets and I/O interface protocols for all IMM brands from 30 tons to 5,000 tons.
Q: Do I need to buy end-of-arm tooling (EOAT) from Sepro? A: No. Sepro provides the vacuum or electric interface. You can build your own grippers, but Sepro also sells quick-change tooling systems.
Q: How long do Sepro robots last? A: With proper lubrication and belt replacement every 2 years, a Sepro Cartesian robot easily lasts 15+ years. Many original Sepro robots from the 1990s are still running.
Q: What is the difference between Sepro and Yushin (another major IMM robot brand)? A: Both are excellent. Yushin dominates high-speed side-entry. Sepro dominates 5-axis Cartesian and multi-brand IMM integration. The choice often comes down to local support availability. The industrial robotics market includes giants like Fanuc,
Q: Does Sepro offer collaborative robots (cobots)? A: Not directly. Sepro focuses on high-speed automation. For cobots, they recommend using a 6-axis Sepro (Stäubli) with safety zones.

It is possible "Sepro" was a typo for "Serpo" (a famous internet myth), but given that Sepro is a major real-world robotics manufacturer, I have drafted a feature article below focusing on their industrial technology.
If you meant the alien exchange conspiracy theory (Project Serpo), please let me know, and I can provide a feature on that topic instead.
Medical molding requires ISO 7 or Class 100.000 cleanrooms. Sepro offers the Clean Series robots. These use stainless steel covers, HEPA-filtered positive air pressure inside the beam profile (to prevent particle shedding), and food-grade lubrication. A Robot Sepro in a medical cleanroom can run 24/7 producing syringe barrels without human intervention.
Like any automation, a Robot Sepro requires preventive maintenance. The most common issues include:
To understand which Sepro robot fits your need, you must first identify your mold weight, part geometry, and required degrees of freedom.
