DK Series Vertical Clamping Horizontal Injection Machines

DK Series pairs a tie-bar-guided vertical clamp with a side-mounted injection unit for larger insert molding, metal-insert parts, and projects that need higher shot capacity.

The mold closes vertically so inserts stay naturally supported, while material enters from the side to match larger shot requirements and side-gate mold designs.

DK Series Platform

Vertical clamping meets horizontal injection - built for larger-tonnage insert molding

DK Series separates the injection axis from the clamp axis. The mold closes vertically - gravity holds inserts in place during mold close, exactly like DA and DC. But the injection unit enters from the side, enabling larger shot sizes, longer barrels, and higher plasticizing capacity. Covering 120T to 400T, DK is the platform for automotive, industrial, and large metal-insert applications that outgrow DA's injection capacity.

  • Horizontal injection Larger shot sizes, longer barrels, higher throughput for engineering materials
  • High-tonnage range 120T-400T across 15 models - includes the DK-4000 flagship at 400T
  • Independent injection unit Injection axis separated from clamp - easier maintenance, flexible mold gating
  • Tie-bar guided clamp Four tie-bars support platen alignment at high tonnages for stable molding conditions

Key Structure

Vertical clamp | Horizontal injection - two axes, one machine

DK Series uses a conventional tie-bar-guided vertical clamping unit paired with a horizontally mounted injection unit. The mold opens and closes vertically - gravity keeps inserts seated during mold close. Material is injected from the side through an independently positioned barrel and screw. This separation of clamp and injection axes allows DK to handle larger shot weights and higher plasticizing rates than vertically injected machines of comparable tonnage.

Clamping
Vertical clamping with four tie-bars for precise platen alignment at high tonnage
Injection
Horizontal injection enters from the side - larger shot sizes, longer barrel, independent positioning
Tonnage
120T-400T across 15 models - the highest-tonnage range in this vertical machine lineup

Why horizontal injection matters

  • - Larger shot capacity: Horizontal barrels can be longer and larger in diameter - DK-4000 delivers up to 2,316g shot weight, well beyond what a vertical injection unit of equivalent footprint can handle.
  • - Better for engineering materials: Longer residence time in the barrel, more temperature control zones, and higher plasticizing rates suit glass-filled, heat-stabilized, and high-viscosity engineering resins.
  • - Side-gate molding: Horizontal injection naturally aligns with side-gated mold designs - common in automotive and industrial parts where the gate must be positioned away from visible surfaces.
  • - Maintenance access: The injection unit sits beside the clamp, not above it. Barrel cleaning, screw changes, and nozzle maintenance can be performed without working over the mold area.

DK Series vertical clamping horizontal injection fixed platen machine

Table Configuration

Standard - Fixed Platen

6 models | DK-1200 - DK-4000

Vertical clamping keeps inserts gravity-seated while the mold closes along the vertical axis. The injection unit enters horizontally from the side - a configuration that suits larger shot sizes and allows the injection unit to be positioned independently of the clamp. Available from 120T to 400T, including the DK-4000 flagship.

DK Series vertical clamping horizontal injection double slide table machine

Table Configuration

Double Slide Table

5 models | DK-1200DS - DK-3000DS

Two alternating lower platens with the same vertical-clamp horizontal-injection architecture. While one mold is clamped and injected from the side, the operator loads inserts and removes parts at the other station. The horizontal injection unit stays fixed - slides move only the lower platens, keeping the injection axis stable.

DK Series vertical clamping horizontal injection rotary table machine

Table Configuration

Rotary Table

4 models | DK-1200R - DK-2100R

A rotating multi-station table for continuous production. Operators load inserts at the loading station while molding and horizontal injection run at the clamp station. Commonly selected for larger insert molding, metal-insert overmolding, and automotive component production where cycle time and part consistency are critical.

Frequently Asked Questions About DK Series

What makes DK Series different from DA and DC Series?
DK Series uses horizontal injection combined with vertical clamping. Unlike DA Series (vertical injection + vertical clamping), DC Series is defined by tie-bar-less vertical clamping and its injection direction depends on configuration. DK injects material from the side. This horizontal injection arrangement supports larger shot sizes and allows the injection unit to be positioned independently of the clamp - making DK the right choice for larger insert molding and higher-tonnage industrial applications from 120T to 400T.
What types of products are commonly reviewed for DK Series machines?
DK Series is built for larger insert molding applications where higher clamp forces and larger shot weights are required. Typical products include automotive interior and under-hood components, large metal-insert overmolded parts, industrial connectors and housings, and structural parts with embedded metal components. The horizontal injection unit is well-suited to processing engineering-grade materials at higher throughput.
Which table configurations does DK Series support?
DK Series supports three main table configurations: fixed platen for stable single-station molding (including the 400T DK-4000 flagship), double slide table for alternating loading-and-molding workflows, and rotary table for multi-station continuous production. All configurations share the same vertical-clamp horizontal-injection architecture.
Why choose horizontal injection over vertical injection?
Horizontal injection separates the injection unit from the clamp axis. This allows for larger, independently positioned injection units - useful when processing materials that require longer barrels, higher plasticizing capacity, or when the mold design benefits from side-gate injection. It also simplifies maintenance access to the injection unit without interfering with the mold area.
How do I determine the right DK Series model and tonnage for my application?
Model selection depends on your mold dimensions (must fit within the tie-bar spacing), required clamp force, shot weight, material type, and insert loading workflow.
