DA, DC, and DK Machine Structure Selection Guide

Compare DA, DC, and DK vertical molding machine structures by reviewing clamping structure, injection direction, mold access, gate layout, and application fit.

2026-07-11 | 10 min read | Category: Choose by Machine Structure

DA, DC, and DK are Deboge machine structure families used in different vertical molding discussions. The correct choice depends on clamping structure, injection direction, mold access, gate layout, loading workflow, and the part being molded.

This guide keeps the terminology precise. DA Series combines vertical clamping with vertical injection. DC Series is defined by tie-bar-less vertical clamping, and injection direction depends on configuration. DK Series combines vertical clamping with horizontal injection.

Quick Answer

Use DA when a standard vertical clamping and vertical injection structure fits the mold and loading workflow. Review DC when open side access or tie-bar-less clamping is important. Review DK when vertical clamping is useful but horizontal injection better matches shot, gate, or mold layout needs.

When This Guide Is Most Useful

Use this guide when a project is not just choosing a table type but comparing machine structure families. It is especially useful when the team is unsure whether the key issue is mold access, injection direction, shot capacity, table layout, or insert loading.

Selection Path

Separate clamping direction from injection direction

The word vertical often describes the clamping structure, not necessarily the injection direction. A project can need vertical clamping for loading access while the injection unit direction remains a separate technical decision.

Review DA Series for standard vertical structure needs

DA Series Standard Vertical Injection Molding Machines are a practical starting point when vertical clamping and vertical injection fit the product, mold concept, and table configuration.

Review DC Series when side access matters

DC Series Tie-bar-less Vertical Clamping Machines should be discussed when tie-bars would limit loading, cable routing, fixture movement, mold access, or automation approach. Do not describe DC as only horizontal injection; the defining feature is tie-bar-less vertical clamping.

Review DK Series when horizontal injection is part of the mold plan

DK Series Vertical Clamping Horizontal Injection Machines combine vertical clamping with horizontal injection. This structure can be reviewed when the mold, gate direction, shot requirement, or plasticizing discussion points toward a horizontal injection unit.

Decision Points to Review

Review pointWhy it mattersWhat to prepare
Clamping structureIt affects mold opening, platen support, and loading access.Mold concept, clamp access needs, and fixture movement.
Injection directionIt affects gate layout, barrel position, and mold design.Gate concept, material path, and shot requirement.
Side accessCables, large inserts, and robots may need a more open approach.Loading photos, insert size, cable routing, and robot path if planned.
Table configurationThe table still affects loading rhythm even after structure is chosen.Fixed, slide, or rotary workflow assumptions.

How to Compare Common Options

OptionWhen it may fitWhat to verify
DA SeriesStandard vertical clamping and vertical injection fit the project.Mold access, injection direction, and table configuration.
DC SeriesTie-bars limit access or side approach for loading, cables, fixtures, or automation.That tie-bar-less clamping is genuinely needed and injection direction is confirmed separately.
DK SeriesVertical clamping is useful and horizontal injection better supports the mold or shot discussion.Gate layout, barrel position, and mold access around the horizontal injection unit.

Information to Prepare Before Asking for a Recommendation

InformationWhy Deboge needs it
Part and insert drawingsThey show whether standard access is enough or open side access is needed.
Mold and gate conceptStructure review depends on how material enters the mold.
Loading workflowSide loading, cable routing, and fixture movement can change the structure discussion.
Material and shot expectationsThe injection unit discussion depends on material and project scope.

Common Mistakes to Avoid

  • Calling DC Series only a horizontal injection machine.
  • Calling DK Series simply a vertical injection machine.
  • Choosing a structure family before reviewing gate direction and mold access.
  • Treating DA, DC, and DK as price levels instead of structural options.

How This Guide Connects to Other Resources

Use this guide together with the table configuration guide. After the structure family is clearer, review the application-specific guides for insert molding, cable connector overmolding, thermoset, LSR, or automation planning.

FAQ

What is the main difference between DA, DC, and DK structures?

DA uses standard vertical clamping with vertical injection, DC is defined by tie-bar-less vertical clamping, and DK combines vertical clamping with horizontal injection.

Does DC Series always mean horizontal injection?

No. DC Series means tie-bar-less vertical clamping. Injection direction depends on the selected configuration and should be confirmed separately.

When should DK Series be reviewed?

Review DK when vertical clamping is useful but horizontal injection better matches the mold, gate layout, shot requirement, or plasticizing discussion.

Can table configuration still matter after choosing DA, DC, or DK?

Yes. Table configuration affects loading, unloading, station separation, and production rhythm, so it should be reviewed together with the structure family.
