The C Series combines tieless vertical clamping with horizontal injection for maximum mold accessibility in a compact package. No tie bars means completely unobstructed access to the mold from all sides. Inserts load freely, robots move without interference, and mold changes are fast. Horizontal injection delivers the plasticising performance and shot capacity advantages of a side-mounted screw with easy maintenance access.
Available in two clamping sizes, C55 (55T) and C85 (85T), each offered in standard, double-slide, and rotary configurations. Round rotary platens (φ880mm on C55R, φ980mm on C85R) for rotary and two-colour applications. Compact machine dimensions with low footprint. Hydraulic servo system standard on slide and rotary variants. Part of Chen Hsong’s vertical platform family, sharing common components with V, W, and H Series.
Both are tieless, but they differ in injection orientation and tonnage range. The W Series uses vertical injection with tieless two-platen clamping and covers 85 to 600 tonnes with a low work height design. The C Series uses horizontal injection with tieless vertical clamping and covers 55 to 85 tonnes in a more compact package.
Choose the C Series when you need maximum accessibility in a small footprint with horizontal injection advantages. Choose the W Series when you need higher tonnage, larger platens, or low work height ergonomics.
Tie bars create physical obstacles that robots must navigate around to reach the mold area. In tieless machines, robots have clear, straight-line paths to load inserts and remove parts from any direction.
This simplifies robot programming, reduces cycle time, and allows simpler end-of-arm tooling. For automated production cells where multiple robots or peripherals need to access the mold area, tieless clamping eliminates the biggest physical constraint.
The C Series is designed for compact, automation-friendly insert molding: small electrical connectors, precision electronic components, small automotive sensors, and any application where maximum mold accessibility in a small footprint is critical. The tieless design is especially valuable in automated production cells with robotic insert loading.
Chen Hsong provides installation, training, maintenance, and technical support through more than 120 service locations worldwide.
The vertical series shares common components across V, W, H, and C variants, ensuring reliable spare parts availability.
