A vendor explainer walks through how articulated robot arms combine jointed axes, sensors, and servo-driven actuators to automate injection molding and other industrial tasks. [S1]
For a specifying engineer, the article is a quick vocabulary check on degrees of freedom, servo actuation, teach versus offline programming, and the kind of end-of-arm tooling the vendor expects to integrate. It also names a specific product family, the High Speed Robot SFK Series, so you can ask for datasheets, repeatability figures, and cycle-time claims before quoting it on a cell. [S1]
What the source actually says
The piece is a vendor explainer that defines an articulated robot arm as a mechanical arm built from multiple rotating joints connected by links, and contrasts it with traditional linear robots. [S1]
It frames degrees of freedom as the count of independent directions a joint can move, and calls out a 6-DOF arm as the typical configuration for handling a variety of operations in three-dimensional space. [S1]
The article ties the arm to its control system, its sensor feedback loop, and its actuator set, then closes with application notes for injection molding, general manufacturing, and healthcare. [S1]
Numbers, names, and product references given
The only named product in the body is the High Speed Robot SFK Series, described as a high-speed articulated arm used for automated part removal, waste handling, and packaging in injection molding lines. [S1]
Surgical robotics is illustrated by name with the Da Vinci Surgical System, cited as an articulated robot arm used to assist surgeons in complex procedures. [S1]
Actuator options listed are electric motors, pneumatic devices, and hydraulic actuators, with servo motors called out as the common choice in most industrial robot arms for high precision and reliable motion control. [S1]
No quantitative specifications such as payload, reach, repeatability, cycle time, or axis count for the SFK Series appear in the body. [S1]
What it means for specifying an articulated robot
For a cell layout, the article reinforces the usual decision axes: joint count and DOF, choice of servo versus pneumatic or hydraulic actuation, sensor coverage for position, load, speed, and temperature, and programming style between teach pendant and offline paths. [S1]
For injection molding specifically, it positions the articulated arm as the handler that moves parts from the mold to a designated location, which is the same scope most sprue pickers and traverse robots cover, so the differentiation claim will live in rated speed and rated payload, neither of which the article supplies. [S1]
Tooling language in the body is generic, naming grippers, welding guns, and other specialized tools as the actuators that carry out the task, which is consistent with how suppliers usually scope an end-effector interface rather than committing to a specific coupling or payload class. [S1]
How to check the primary source
The article is hosted at samfacc.com under the title How Does an Articulated Robot Arm Work, and a published timestamp of 2025-09-11 is shown on the page, which is worth noting since the index date in the source record is 18 Aug 2026. [S1]
Before specifying the High Speed Robot SFK Series, request the vendor datasheet for axis count, rated payload, reach, repeatability, and cycle time on a representative molded part, and confirm the control system support for teach and offline programming against the cell PLC. [S1]
Cross-check the Da Vinci Surgical System reference through Intuitive Surgical documentation if the healthcare context is relevant to your facility, since the article uses it as an illustration rather than a product the vendor sells. [S1]
