Chen Hsong V-S Single-Slide vertical injection molding machine with sliding lower platen

V-S Single-Slide

V-S Single-Slide

Slide Out. Load Up. Mold.

The V-S Single-Slide adds a sliding lower platen to the V Series platform. The lower platen slides out from under the clamping unit, giving operators clear access to load inserts, position components, and remove finished parts without reaching into the mold area. This improves ergonomics, reduces cycle time, and lowers the risk of misplaced inserts compared to a fixed platen design. 

Same vertical clamping and injection performance as the V Standard, with ejector position scale control, ejector return confirmation, and ejector holding function all standard on the sliding platen variant. Slide plate positioning device available for precise and repeatable platen return. Six models from 35 to 200 tonnes. Part of Chen Hsong’s vertical platform family with a clear upgrade path to Double-Slide or Rotary configurations as production volume grows. 

Core Values

Sliding Platen for Easier Insert Loading

  • Lower platen slides out for clear, unobstructed access to the mold area
  • Operators load inserts and remove parts without reaching into the machine
  • Improved ergonomics reduces operator fatigue during repetitive insert loading
  • Lower risk of misplaced inserts compared to fixed platen designs

Enhanced Ejection for Slide Operation

  • Ejector position scale control standard for precise part release on the sliding platen
  • Ejector return confirmation and ejector holding function standard
  • Slide plate positioning device available for precise and repeatable platen return
  • Safety light curtain and acrylic safety door with interlock available

Same Platform, Same Precision

  • Same vertical clamping and injection performance as the V Standard
  • Six models from 35 to 200 tonnes: V35S, V55S, V85S, V120S, V160S, V200S
  • Standard high-riser components for thicker mold compatibility
  • Screw diameter options from φ22mm to φ65mm, shot weight 49g to 740g (PS)

Scalable Upgrade Path

  • Upgrade to V-SD Double-Slide when you need alternating load/mold stations
  • Upgrade to V-R Rotary for highest throughput and two-colour applications
  • Same operator training, mold standards, and spare parts across all V Series variants
  • Multi-station models support independent injection parameter adjustment per station

FAQ

01What Is The Difference Between The V-S Single-Slide And The V Standard?

Both share the same vertical clamping and injection platform. The V Standard has a fixed lower platen. The V-S adds a sliding lower platen that slides out for easier insert loading and part removal.

The V-S also adds ejector position scale control, ejector return confirmation, and ejector holding function as standard. Choose the V-S when operators need clear access to load inserts or when ergonomics is a priority.

Choose the V-S Single-Slide when insert loading time is short enough that one station is sufficient, or when floor space is limited.

Choose the V-SD Double-Slide when insert loading takes significant time and you want to load inserts on one side while the other side molds, effectively doubling output. The V-SD requires more floor width for the two sliding platens.

The V-S is ideal for insert molding applications where operators manually load inserts: electrical connectors, terminals, automotive components, cable assemblies, and precision plastic parts with metal inserts.

The sliding platen is especially valuable when inserts are delicate, require precise positioning, or when multiple inserts must be loaded per cycle.

Yes. The V-S includes safety light curtain and acrylic safety door with interlock as standard on the larger models. Robot interface is supported. Slide plate positioning device is available for automated workflows requiring precise and repeatable platen positioning.
