Six Axis Industrial Robot Arm Applications and Benefits

Six axis robots are ideal for tasks requiring multi-directional flexibility, such as machine tending, assembly, gluing, welding, inspection, deburring, and palletizing. In injection molding environments, they excel at secondary operations downstream of the press — including gate trimming, insert loading, kitting, and end-of-line pack-out — where complex part orientations and confined workspaces demand articulated dexterity.

A standard 6-axis robot has six rotational joints providing full spatial reach, while Yushin's OB7 cobot adds a seventh axis for human arm-like redundant dexterity. The extra axis lets the OB7 navigate around obstacles and work in confined spaces unreachable by 6-axis designs. The OB7 is also force-limited and safety-rated for shared human-robot workspaces without fixed fencing.

Yes. Six axis robots like the OB7 cobot are well-suited for machine tending in injection molding environments. They handle tasks such as insert loading, gate trimming, part transfer, and quality inspection on secondary operations downstream of the press. Their articulated reach allows them to work within compact cell layouts and alongside human operators under appropriate risk assessment.

Yushin's robot lineup spans payloads from under 1 kg for pneumatic sprue pickers up to 80+ kg for the MKA-2000S heavy-duty traverse robot. For collaborative 6-axis and 7-axis applications, the OB7 cobot handles up to 5–7 kg. The PA Series compact palletizing robot supports up to 40 kg including the end-of-arm tool, covering most downstream packaging and palletizing needs.

Six axis robot arms are used across automotive, medical device, pharmaceutical packaging, food and beverage packaging, consumer goods, and electronics manufacturing. In plastics processing specifically, they serve injection molders producing automotive trim, medical disposables, caps and closures, appliance components, and precision optical parts requiring flexible end-of-arm automation beyond what fixed-axis take-out robots provide.

Modern six axis cobots like the OB7 are designed for operator-tier programming through teach-by-demonstration and graphical recipe builders — no robotics specialist is required. Yushin's broader lineup also supports intuitive color teach pendants, Cycle-Up functions, and PC-based Flexible Teaching software, enabling production staff to set up, adjust, and retask robots without dedicated programming expertise.
