Robot Sepro: The Complete Guide to Automation in Plastics Manufacturing

In the fast-paced world of plastics injection molding, speed, precision, and uptime are everything. As manufacturers face increasing pressure to lower costs while improving quality, one name has risen as a global benchmark: Robot Sepro.

But what exactly is a "Robot Sepro"? Is it a single machine, a brand, or a technology? For engineers and plant managers, understanding the Sepro ecosystem—from sprue pickers to high-speed Cartesian robots and 6-axis articulated units—is critical for staying competitive. robot sepro

This article dives deep into Sepro’s history, its product lineup, key technologies, and how Sepro robots are transforming injection molding floors across automotive, medical, packaging, and consumer goods industries. Robot Sepro: The Complete Guide to Automation in

Typical benefits

  • Productivity: shorter cycle times and higher throughput via continuous, repeatable operation.
  • Quality: consistent part handling and automated vision inspection reduce defects.
  • Flexibility: modular cells and configurable EOAT support multiple part families and quick changeovers.
  • Safety: enclosed or fenced cells with interlocks reduce operator exposure to hazards.
  • ROI: lower direct labor and reduced scrap often recoup investment within a few quarters to a couple of years, depending on application.

B. Drive & Motion System

  • AC Servo Motors (all-electric): Sepro pioneered all-electric Cartesian robots. No hydraulics. This provides cleanliness (ISO 7 class cleanroom), energy efficiency (up to 85% less energy than pneumatic), and high repeatability.
  • Linear Guides & Rack/Pinion: High-grade Japanese THK or German Rexroth rails for zero-backlash motion.
  • Max Speed: Typically 2–3 m/s (transverse axis) with accelerations up to 10 m/s². Extraction strokes from 300 mm to over 2500 mm.

Automotive

  • Part type: Dashboard carriers, bumpers, door panels.
  • Robot needed: Sepro Force (5-axis, 100 kg payload) for removing large parts and placing them into a trim fixture.
